Matic Network's Great Reddit Scaling Bake-Off submission

The Matic team has put together a Proof-of-Concept for the Reddit Scaling Bake-Off. We think Matic is the most apt solution for the scaling requirements of Reddit, keeping in mind it’s current and future needs.
We believe that the Matic Layer 2 platform is the most complete solution out there in terms of the features and fits right in with what Reddit requires:
TL;DR: The Matic sidechain processed 3mn transactions over 12 hours with total gas fees of USD 3.52 as part of the Great Reddit Scaling Bake-Off PoC.
The PoC used a few addresses only for the purpose of the demo, and the total throughput with millions of user addresses can go up to 7200 TPS per sidechain and these 3mn transactions could've been completed in a matter of 10-11mins.
The PoC touches upon various aspects of the solution required – scalability that will need to meet Reddit’s requirements over time (more subreddits using Community Points), faster transaction times, inexpensive minting of Community Points, decentralization, accessible developer tooling, use of meta-transactions to pay for gas on behalf of users, open-source code, extensibility, ability to exit back to Ethereum, if needed and more.
What is Matic?
Matic Network is a Layer 2 scaling solution for Ethereum that provides hybrid Proof-of-Stake and Plasma-enabled sidechains. We just released version 1 of our mainnet in May 2020 – https://blog.matic.network/the-matic-network-mainnet-is-now-live/.
Matic implements an account-based variant of MoreVP (More Viable Plasma), with support for custom Plasma predicates. The Plasma framework with predicates is used to guarantee the security of assets and specific smart contracts using Plasma predicates, while arbitrary smart contracts are secured by a Proof-of-Stake network, with validators staking Matic tokens on Ethereum. Matic sidechains are essentially EVM-enabled chains and are conducive to ready deployment of Solidity smart contracts, essentially making it an easy tool for Ethereum developers to use it for scaling their DApps/Protocols.
We are submitting the following:
More details on the submission can be found on our blog post on this: https://blog.matic.network/matic-goes-to-the-great-reddit-scaling-bakeoff/.
Looking forward to what's in store!

Polkadot (DOT) coin Price Prediction 2021

Polkadot (DOT) coin Price Prediction 2021
What is Polkadot?
Polkadot is a scalable, multi-chain technology that was developed by Gavin Wood, one of the co-founders of the Ethereum project. Basically Polkadot is a network that connects blockchains. The platform allows various blockchains to transfer messages, including value, and to share unique features.
The project main goal is to transform the existing structure of the Internet to Web3 – an absolutely innovative and decentralized network.
by StealthEX
The internal token of the Polkadot network is called DOT. This token allows owners to vote on possible changes to the protocol, which are automatically rolled out across the network if the consensus is reached. The DOT crypto also serves for staking and bonding purposes.
Today Polkadot is one of the TOP-5 cryptocurrencies by market capitalization.

Polkadot Statistics

Polkadot achievements and future plans

Recently the Polkadot project developers have the following main updates and news:
• The Polkadot Ecosystem Fund and the Polkadot Incubator were released.
• The Kusama network – an unaudited version of Polkadot was launched.
• The team introduced a new testnet for Polkadot and Kusama called Westend.
• On 26 May 2020 Web3 Foundation launched the initial version of Polkadot.
• The Polkadot team started the first vote on the fledgling Polkadot network.
• Polkadot’s parachain testnet called Rococo was introduced.
• A huge number of workshops, both online and in-person were given around the world on a variety of topics — validation, Polkadot basics, Kusama, addresses, security, and Substrate.

What to expect in the future?

Currently, the Polkadot project is on the phase of “Enabling Balance Transfers and Denomination Day”. Once governance enables parachain auctions and XCMP, Polkadot will have a fully functional Relay Chain. After that, the token holders will decide how the project will develop further.

Bold move from Acala: EVM support coming!

The Acala team recently announced support for EVM-based smart contracts in their parachain. In short, this means that smart contracts that run on Ethereum can be run on their parachain. As they are targetting DeFi use case, I think that’s a great way to garner adoption. It’s also a bold strategy as I will outline below.
 
Some background on the Acala team
The team is actually composed to two teams who were already building for the Polkadot ecosystem. Those teams are PolkaWallet and Laminar. The latter focus on runtime engineering (“building chains”), while PolkaWallet is a mobile-first wallet for Polkadot (and Kusama).
These teams, both as separate entities and together as Acala, applied for grants in the Web3 Foundation grant program Each application was successful too. I know this since I prepared their contracts. 😉
In my dealings with them they were always professional and honest, plus their enthusiasm and dedication to Polkadot is unsurpassed.
 
What is Acala?
In their own words:  
“A decentralized stablecoin platform powering cross-blockchain open finance applications.” (Source)
The team are aiming to be the “decentralized financial hub of Polkadot” with “a suite of financial primitives: a multi-collateralized stablecoin backed by cross-chain assets like Bitcoin, a trustless staking derivative, and a decentralized exchange.” (Source)
Add in wallet support and you have a very compelling package that should entice both builders and users to the project. Merely building a blockchain doesn’t guarantee wallet support from day one, nor does it guarantee developers will want to build for it, but this is where Acala is making great headway to overcome those challenges.
For users, having access to a stablecoin is a big must and is something that I was personally wrong about. I didn’t think they would be so useful (+1 XP for me). Moreover, I suspect there could be a governance token coming too, one which is also the fuel for the contracts. I can see these features intertwining into some interesting token economics.
 
A bold strategy
A strong team announcing support for EVM-flavoured smart contracts is great for Polkadot, but I think it may ruffle a few feathers with other teams who are also planning to offer EVM compatibility. This is a bold move, but one that makes sense. Being able to attract DeFi developers to Polkadot is easier if there is a nice migration path from Ethereum to Polkadot.
It feels like a competitive move as EVM-compatible parachains will have an overlap in target audience. This is one of the interesting aspects of the blockchain space: you have open-source software and a general design principle of interconnectivity such that collaboration is highly encouraged, yet there is a limited number of developers. Acala is collaboratively in the sense that it should offer a stablecoin.
That said, there is some natural differentiation between the projects too. Should DeFi projects naturally adopt Acala, then I see this as an opportunity for non-DeFi projects to migrate to the other parachains (e.g. Plasm and Moonbeam). Ultimately, that may not be such a bad thing. Less projects on the same chain (“shard”) means less congestion.
The launching of the new parachains is something to watch closely over the next year or so; however, that is the subject of a future blog!
 
Acala Tokens
At the moment Acala are not selling any tokens to the public. If you see anything listed on Uniswap or elsewhere in the Ethereum ecosystem (e.g. as an ERC-20) then be very skeptical.
There has been some private sales to professional investors, but nothing public. There is no published date for a token sale, so currently there is no known way for small investors to get involved. Although I believe it could happen before launch. The team have a roadmap on their website which suggests a potential parachain launch of Q3 2020, but I do fear that timeline might slip.
Personally, I’d really like to buy some but as a non-professional investor of only modest means I will be waiting like everyone else in the community. While I believe Acala is a strong team I think everyone should do their own research and make up their own mind.

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014
The demonstration was executed using this tool. The results can be seen in the following blocks:

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Tools, Infrastructure & Documentation

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20

  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

If you’ve been an Ankr user long enough (or have taken a look around our new website), you’ll know that we’ve positioned ourselves as the “Gateway to Web3”. So, what exactly is Web3? And by extension, what is Web1 and Web2? And lastly, what role does Ankr play in the grand scheme of things?
Let’s start with a brief look at what Web1 and Web2 were and how they paved the road for where we are today.

Web1 & Web2 — A brief stroll down the information highway

The Internet’s origin was military — at that time, it was called Arpanet. It was designed as a network that could even survive a nuclear attack! Due to its military roots, Web1 was mostly information based in one direction. Superiors would broadcast information to subordinates and easily coordinate.
This is how we saw our first iteration of the Internet — lots of directories, resources, and otherwise static information.
Web 2.0 made the information stream both ways. And with that simple change, the possibilities of the Internet exploded. User-generated content went to create online communities, social networks. Also, it allowed users to quickly develop websites on their own.

Web3 — The current and future internet

While Web2 is focused on empowering users the ability to upload content (think YouTube, social media platforms, blogs, etc.), Web3 builds on this as websites have become smarter. Instead of just passively receiving data from users, algorithms, and machine learning allow the websites to make predictions based on your data for higher engagement and immersion.
Think of anytime Amazon suggested something, and it happened to be perfect for your needs (or wants — we don’t blame you!).
  • Netflix suggesting a new show
  • Spotify delivering weekly playlists based on the music you listen to
  • YouTube autoplaying the next video
and much more — these are all examples of Web 3 in our everyday life.
The thing these services, and all the dozens of other websites you interact with daily, have in common is their need for data. In today’s age, whichever company can process data faster, more accurately, and make better forecasts because of it are the winners in the end.
Blockchain technology looks to be the next frontier in this information race as it offers new applications that were either impossible or impractical to execute earlier.

Ankr’s role in the new internet

Information is the digital oil for this era. So anything that revolutionizes information itself is a big deal (aka blockchain technology).
Regardless of the use case, infrastructure will always be something that’s needed. Whether that’s small, passionate teams like Deecrypt.io or large renown exchanges transacting millions of dollars in digital assets daily like Binance, we proudly power those on the onward march forward.

While a blockchain is where the information resides, immutable once confirmed by the network, connecting to them in an easy way is key for adoption of the technology and applications built on it.
In our global economy, having access to applications and the protocols they are built on from anywhere all the time is a necessity. This is particularly true in our industry, where decentralization is the unspoken requirement.
But it can be time and money consuming to handle all the technical details, whether you want to deploy a node and earn staking rewards, analyze on-chain data or build decentralized applications yourself.

Ankr is for everyone

We offer solutions for all mentioned participants in blockchain ecosystems: one-click deployment of staking nodes to earn rewards, easy access to on-chain data via a wide array of full nodes and APIs connecting you to the most popular blockchains to build on, such as Ethereum, Binance (Smart) Chain and Polkadot.
Web3 is here — and it is powered by blockchains. Don’t miss out on the future of the Internet. Stake, integrate, analyze and build without studying tons of complex documentation. Head over to app.ankr.com and become a part of Web3 today!

Ethereum JavaScript Libraries: web3.js vs. ethers.js

Web3.js and ethers.js are JavaScript libraries that allow developers to interact with the Ethereum blockchain. They are both great libraries - either library will likely meet the needs of most Ethereum developers. This tutorial is a comparison of web3.js and ethers.js, focusing on their similarities and differences, so that you can better understand the nuances of the libraries. It is written with the intent of educating developers to understand the tradeoffs between the two libraries to be able to make a decision of which library to use for their particular use case. This article includes resources that may be useful for those who are new to blockchain development or programming in general.
TL;DR: Both libraries work. For your use case, one library may be better for you.

dxDAO aims to power DeFi protocols through decentralized governance

I found this article on internet. It's repost of it to help educate people about all DXDao advantages:
These are positive and necessary steps for DeFi. The new governance structures are intended to help coordinate across community stakeholders and make better decisions. These dynamics are influenced by the issues covered in Dose of DeFi, but I believe they deserve their own focused analysis.
Govern This aims to educate token holders and make them better voters. Emphasis will be placed on specific governance proposals and relaying community governance discussions on forums and weekly calls.
Governance is a coordination technology that has helped countries and companies build more than the sum of their parts. Blockchains are also a coordination technology, but for computers, not humans***.*** Govern This will track the development of the melding of these two over the coming years.
Like governance, Govern This is a work in progress. I would appreciate any feedback on format, topics covered or any other suggestions to make the newsletter better. Just hit reply.
The first issue of Govern This is below. Please click here to subscribe.

dxDAO aims to power DeFi protocols through decentralized governance
Gnosis launched a long-awaited DEX last week with batched auctions for low-liquidity trade pairs. The front-end, Mesa.Eth.Link is owned and operated by dxDAO, a decentralized collective that hopes to power other DeFi protocols.
While dYdX does not have any specific governance plans (yet), this tweet from dYdX founder Antonio Juliano is a common approach to governance.
📷Antonio Juliano @AntonioMJuliano3) 0x should focus less on governance in the short term. It’s way more important to first build something with a large amount of adoption that’s worth governing
December 6th 2018
3 Retweets62 Likes
The tweet at the end of 2018 was in response to 0x and its native token, ZRX. The project was popular but the token had no use case outside of governance.
This governance strategy – build now, decentralize later – is widely accepted in the space and is perhaps best exemplified by the A16Z’s Jesse Walden’s post, “Progressive Decentralization: A Playbook for Building Crypto Applications”, which the A16Z-backed Compound has essentially implemented (more in the section below).
dxDAO, on the other hand, maintains that decentralization must come at the beginning or else the core team and investors will have an outsized influence on the project in formal (token voting) or informal ways (dictators for life).
Background
dxDAO was launched in May 2019, spun out of a collaboration between Gnosis and DAOstack over managing the DutchX platform. dxDAO’s key governance design is separating financial rights to the DAO (DXD) from voting power over the DAO (Reputation). It used an Edgeware-style lock drop to distribute reputation to stakeholders in May of last year. Any user could lock up ETH or an accepted ERC-20 for a month and receive Reputation, which are voting rights in dxDAO, even though it is not a token and cannot be transferred.
Over 400 unique Ethereum addresses participated in the distribution scheme. Gnosis went through a pretty extensive process in July 2019 to “step back” from its involvement in the DAO, and since then, the community and dxDAO have aligned behind a mission of “putting the ‘De’ in Decentralized Finance”.
Following on last week’s launch of Mesa.ETH.Link, dxDAO is conducting a fundraiser or (“DAICO”?) to help fund its new slate of DeFi products, including a prediction market platform (Omen) and a privacy-centric DeFi dashboard (Mix).
Project launch is typically when a project is most centralized. Execution is hard and direction and accountability are important. dxDAO’s approach will be an interesting counterexample to the “decentralize later” trend and may provide insight into new governance strategies.
Click here for more information about the dxDAO fundraiser.
Here’s what is on the dxDAO docket this week:
Compound governance goes live, has it found Market-Protocol-Fit?
Since its founding in 2017, Compound has executed with an almost flawless record: no bugs/hacks, a major protocol upgrade and a big name fundraise (twice).
But all of that has been because Compound, the company, has executed well, but can protocol development and the growth of the platform be sustained with community management? We shall see.
Compound’s governance system could not be simpler. Anyone with at least 1% of COMP can submit a proposal of executable code. COMP holders have a 3 day voting period; the proposal passes with a majority of token votes AND a 4% quorum of all COMP tokens.
The 1% minimum for proposal submission is a good anti-Sybil mechanism but it greatly limits participation by small users. There is delegation, so you could imagine a “proposal petition” where you would delegate your COMP to a proposal instead of signing your name.
Compound is clearly taking the “less governance is the best governance” approach. This has worked surprisingly well with Bitcoin and Ethereum, which of course, do not have any formal governance, but those communities clearly have informal governance systems that make decisions.
The biggest governance question for Compound: who is the community?
Market-Protocol-Fit
Other Internet has an intriguing essay on the emergent order from new blockchain tokens and their communities. It is worth a read. It discusses the emergent iteration that blockchains – as a technology and a community – go through to find a niche, both in culture and product.
While it focuses on base-layer blockchains that launch with a token, the essay underscores the most underrated governance element: token distribution. It quotes an insightful tweet from Eric Wall
📷Eric Wall @ercwlA question that keeps me up at night: Is it possible to create a rubbish coin based on advanced bullshit, build a community of misguided fans nevertheless, run it centralized for 5 yrs, hardfork-copy the design of a real working project, keep the community and become a success?
keysheet @keysheet
@ErcWll was one of the first vocal critics of IOTA back in 2017, shortly before the project hit a market cap of $15B. https://t.co/2267e8LEpl Today, the project is down 99% and appears to be brutally falling apart. A thread:
February 13th 2020
17 Retweets163 Likes
Before Bitcoin could harden its code and find ‘Digital Gold’ and before Ethereum found ‘DeFi’ and ships ETH2.0, both needed to find a “a strong community of believers” in order to create a “virtuous cycle between headless brands and infrastructural build-out to progressively realize [their] initial promise.”
Communities are connected through a wide spread token distribution, Bitcoin through cypherpunks and online drugs and Ethereum through a global ICO (what Teo Leibowitz called “The Immaculate ICO”).
$COMP distribution
The biggest “news” has been details about $COMP distribution:
There are no explicit plans yet, but the widely held assumption is that the COMP distribution will be determined by the interest earned and paid by users on the protocol since its inception. This is a clever way that only incentivizes more use of the protocol and is hard to game because interests accrues over time.
But the question still remains, what will the COMP community look like and what values will it espouse? Can emergent cultures arise out of Silicon Valley too?
Here’s what is on the Compound docket this week:
Maker and wBTC, a test case for the MIP process
While Maker had planned to spend Q2 moving forward with their upgraded governance process, most of its focus has been on restoring the Dai peg.
For more on how the Maker governance process has expanded outside the core community, check out the previous edition of Govern This.
Here’s what is on the Maker docket this week:
Governance and Risk meeting (April 23)
Single Collateral Dai shutdown – the process has begun. A poll passed with May 12 as the official SCD shutdown. Just yesterday, an executive just passed yesterday to make the MKR oracle fee-less, which will help with migration. Many in the community think the migration of debt from SCD will do more than enough to restore the peg.
13 MIPs and 2 sub proposals – Core to the new Maker governance process is the “Maker Improvement Proposals (MIPs), which are modeled off of BIPs (for Bitcoin) and EIPs (for Ethereum). The two sub-proposals are to appoint the Smart Contracts Team and assign Charles St. Louis as the MIP editor.
The 13 MIPs are listed below:
- MIP1 (Maker Governance Paradigms)- MIP2 (Launch Period)- MIP3 (Governance Cycle)- MIP4 (MIP Amendment and Removal Process)- MIP5 (Emergency Voting System)- MIP6 (Collateral Onboarding Form/Forum Template)- MIP7 (Onboarding and Offboarding Domain Teams for Collateral Onboarding)- MIP8 (Domain Greenlight)- MIP9 (Community Greenlight)- MIP10 (Oracle Management)- MIP11 (Collateral Onboarding General Risk Model Management)- MIP12 (Collateral and Risk Parameter Management)
By and large, the MIPs codify many of the informal Maker governance processes. There is currently a request for comments period (MIP forum) and there will be an informal poll on Monday, April 27 on whether to proceed with the 13 MIPs and 2 sub proposals. If it’s a “Yes”, than an executive for an official ratification vote would start on May 1 and lasts for 4 days. If it passes, the official governance cycle will begin and the rest of the MIPs will likely be approved from May 4 – 6.
Other Governing Things
That’s it! Feedback definitely appreciated. Just hit reply. Written in Brooklyn where it rained all day. No euchre today, but yesterday was epic.

Alternate funding sources?

So, Stripe ended its support for Bitcoin (back in 2018, and doesn't seem to have any indications of restarting), so this post of mine is pretty moot now, but I did want to raise the question of the possibility of other funding sources for getting monetary credit sent into Cardsphere. I know there is a development cost for every additional way to add funds in, but could we have some means to cast votes for a few more to be added? Digital payment services like Venmo, PayPal, and Square are pretty popular, and there are some payment bridges to cryptocurrencies like CoinGate that would enable multiple cryptocurrencies at once, or using the Javascript "web3" interfaces for browser-extension-based wallets for Ethereum or Tron. Are there other funding sources people would love to use that I'm not thinking of here?

Decentralized Crypto Debit Card and Banking Alternative *Monolith* $TKN

What Is Monolith?
Monolith is a decentralized banking alternative, powered by Ethereum. There are four components of the platform: wallet, card, TKN token and security. Users can, for example, exchange their ETH-based tokens to fiat and load it to Monolith Visa debit card. Spending is available wherever Visa is accepted. TKN token could be used to top-up Monolith card thus waiving community contribution. It’s also the most cost-effective way to top-up one’s card. Every top-up pays 1% community contribution that is sent to the Community Chest. Thanks to the Cash and Burn function TKN holders can redeem their pro-rata share of the Community Chest at any time.
TKN is the community token. It is an ERC-20 token that gives TKN holders the opportunity to share in the success of the Monolith card.
TKN coin is listed on HitBTC, IDEX, Bancor and some other exchanges.
Current market capitalization: $7.2 mil 32 million coins circulating out of 39 million total supply
The chart is looking great, had a slight run up this past week and since corrected 30% lower. This seems like it could be a good contender for a coinbase listing eventually.

RiB Newsletter #14 – Are We Smart (Contract) Yet?

We’re seeing a bunch of interesting Rust blockchain and crypto projects, so this month the “Interesting Things” section is loaded up with news, papers, and project links.
This month, Elrond, appeared on our radar with the launch of their mainnet. Although not written in Rust, it runs Rust smart contracts on its Arwen WASM VM, which itself is based on the Rust Wasmer VM. Along with NEAR, Nervos, and Enigma (and probably others), this continues an encouraging trend of blockchains enabling smart contracts in Rust. See the “Interesting Things” section for examples of Elrond’s Rust contracts.
Rust continues to be popular for research into zero-knowledge proofs, with Microsoft releasing Spartan, a zk-SNARK system without trusted setup.
In RiB news, we published a late one-year anniversary blog post. It has some reflection on the changes to, and growth of, RiB over the last year.
The Awesome Blockchain Rust project, which is maintained by Sun under the rust-in-blockchain GitHub org, has received a stream of updates recently, and is now published as the Awesome-RiB page on rustinblockchain.org.
It’s a pretty good resource for finding blockchain-related Rust projects, with links to many of the more prominent and mature projects noted in the RiB newsletter. It could use more eyes on it though.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
ethers.rs
ethers.rs is an Ethereum & Celo library and wallet implementation, implemented as a port of the ethers.js library to Rust.
Ethereum client programming is usually done in JavaScript with either web3.js or ethers.js, with ethers.js being the newer of the two. These clients communicate to an Ethereum node, typically via JSON-RPC (or, when in the browser, via an “injected” client provider that follows EIP-1193, like MetaMask).
ethers.rs then provides a strongly-typed alternative for writing software that interacts with the Ethereum network.
As of now it is only suited for non-browser use cases, but if you prefer hacking in Rust to JavaScript, as some of us surely do, it is worth looking into for your next Ethereum project.
The author of ethers.rs, Georgios Konstantopoulos, accepts donations to sponsor their work.
Note that there is also a Rust alternative to web3.js, rust-web3.

Verified by Visa is sometimes referred as 3D-SECURE.

Is it expensive? What are the fees?

The fees are kept to a minimum. There is no setup fee, no activation fee, nor domestic point of sale fees. To be explicit here: ordering your card is free and there is no ongoing fee if you don't use it.
The only usage fee users have to cover is a 1% top-up fee and potentially another 1% licensing fee, depending on the token used. Here is an overview of our fee structure.
ℹ Spending TKN & stablecoins (DAI, USDC, USDT, GUSD) in your local currency costs only 1%.
Item Fee
Monthly Fee 0
Card Activation & Shipping 0
Transaction Fee (incurred when topping up non-stable tokens) 1%
Transaction Fee for stablecoins (DAI, USDC, USDT) 0%
Community Contribution (-> Chest) 1%
Domestic Fee Europe Fee International Fee
Payment at Merchant 0% 1.75 % 1.75 %
ATM Withdrawal Free up to 2/month, then £0.75 / €0.85 per withdrawal £1.20 / €1.50 (e.g. if in a UK ATM with € card) £1.75 / €2.00
The licensing fees collected populate the community chest, which is where it gets really exciting!

Where are my funds stored with Monolith?

Your Monolith Account is secured by a non-custodial Ethereum Contract Wallet. Don't panic; let's unpack this:
  1. Your wallet is non-custodial: you and only you have access to the private key, required to sign off transactions. Yay! Freedom, autonomy and sovereignty. However, it also means that you have the responsibility of securing your private key.
  2. It's a contract wallet - your funds are not stored in a "regular" (EOA) Ethereum account. Instead, you own the private key of an EAO that governs a smart contract, where your funds are stored. It allows for the implementation of another layer of security: a logic as to how your funds can move. Learn more
  3. It's an Ethereum wallet - able to store ETH, ERC-20 tokens, and soon NFTs!
The source code of the wallet is not only open-source (GPL3); it's also thoroughly documented to make sure each of our users can understand the functions they interact with daily.
Worried about smart contract failures? The code of our contract wallet has been audited several times by companies including Trail of Bits & New Alchemy) & has an ongoing bug bounty.

What is TKN and Community Chest?

The Community Chest is a smart contract that grows through the proliferation and usage of the card. Every time one of our users top-up his card with any token other than TKN, a 1% licensing fee is charged and sent to the community chest. TKN holders can claim their share of the community chest at any time using Cash & Burn.
Since the TKN community chest is made of the different ERC-20s used in our service, ponderated by their usage, it will eventually become a kind of index backed by the most popular ERC-20 tokens.
As a TKN holder, you are directly incentivised to use and recommend Monolith to your friends. In that sense, TKN is one of the few tokens directly linked to the success of its associated service.
Learn more about TKN with our introduction article

How can I claim my share of the fees collected in the Community Chest?

TKN holders can redeem their fair share of the community chest through the Cash&Burn function. At any time, a TKN holder can use TKN's Cash & Burn function to collect a current pro-rata share of the licensing fees accumulated in the community chest. Their share corresponds to the percentage of TKN burned (relative to the total supply).
Since burning your TKN reduces the total amount of TKN in circulation, it proportionally increases the stake of the community chest which can be claimed by further burning in the future.

The best DApps, which will likely lead the next phase.

The best DApps, which will likely lead the next phase.
Author: Gamals Ahmed, Business Ambassador

https://images.app.goo.gl/2c9rF5ZqfbjBzb2x6
One of the key themes in 2020 is the rise of decentralized financing (DeFi), a new type of financing that works on decentralized protocols and without the need for financial intermediaries. Lately, the number of DeFi apps has increased significantly, but many have not been seen or heard by many of us.
In this Article I will be building a list of the best DApps, which will likely lead the next phase. DeFi apps can be categorized into different subcategories such as:
  • Finance
  • Exchange
  • Insurance
  • Gambling
  • Social
And much more…
Note: Some of the projects in the report categorized into more than one section in the types of dApps.
The rise of DeFi Bitcoin (BTC) was the first implementation of decentralized financing. It enabled individuals to conduct financial transactions with other individuals without the need for a financial intermediary in the digital age. Bitcoin and similar cryptocurrencies were the first wave of DeFi. The second wave of DeFi was enabled by Ethereum blockchain which added another layer of programmability to the blockchain. Now, at the beginning of 2020, individuals and companies can borrow, lend, trade, invest, exchange and store crypto assets in an unreliable way. In 2020, we can expect the amount of money held in lending protocols to increase as long-term investors diversify into interest-bearing offers, especially if the market fails to rise towards the 2017/18 highs. On the other hand, active crypto traders are becoming increasingly interested in decentralized trading offers. The increasing level of money security offered by decentralized trading platforms should not only see an increase in trading of DApp users, but also in the number of non-custodial trading and exchange platforms available.
Lending: DeFi allows anyone to obtain or provide a loan without third party approval. The vast majority of lending products use common cryptocurrencies such as Ether ($ ETH) to secure outstanding loans through over-collateral. Thanks to the emergence of smart contracts, maintenance margins and interest rates can be programmed directly into a borrowing agreement with liquidations occurring automatically if the account balance falls below the specified collateral. The relative benefit gained from supplying different cryptocurrencies is different for the asset and the underlying platform used.

Compound

Source: https://images.app.goo.gl/SGttwo4JWadHTxYe7
Compound is a money market protocol on the Ethereum blockchain — allowing individuals, institutions, and applications to frictionlessly earn interest on or borrow cryptographic assets without having to negotiate with a counterparty or peer. Each market has a dynamic borrowing interest rate, which floats in real-time as market conditions adjust. Compound focuses on allowing borrowers to take out loans and lenders to provide loans by locking their crypto assets into the protocol. The interest rates paid and received by borrowers and lenders are determined by the supply and demand of each crypto asset. Interest rates are generated with every block mined. Loans can be paid back and locked assets can be withdrawn at any time. While DeFi may seem overwhelming complex to the average individual, Compound prides itself on building a product that is digestible for users of all backgrounds. Compound is a protocol on the Ethereum blockchain that establishes money markets, which are pools of assets with algorithmically derived interest rates, based on the supply and demand for the asset. Suppliers (and borrowers) of an asset interact directly with the protocol, earning (and paying) a floating interest rate, without having to negotiate terms such as maturity, interest rate, or collateral with a peer or counterparty. Built on top of that principle is cTokens, Compound’s native token that allows users to earn interest on their money while also being able to transfer, trade, and use that money in other applications. OVERVIEW ABOUT COMPOUND PROTOCOL Compound Finance is a San Francisco based company, which raised an $8.2 M seed round in May of 2018, and a $25M Series A round in November of 2019. Financing rounds were lead by industry giants including but not limited to Andressen Horowitz, Polychain Capital, Coinbase Ventures and Bain Capital Ventures, Compound Finance is a sector-leading lending protocol enabling users to lend and borrow popular cryptocurrencies like Ether, Dai and Tether. Compound leverages audited smart contracts responsible for the storage, management, and facilitation of all pooled capital. Users connect to Compound through web3 wallets like MetaMask with all positions being tracked using interest-earning tokens called cTokens.
Compound recently introduced a governance token — COMP. It holds no economic benefits and is solely used to vote on protocol proposals. The distribution of COMP has absolutely exceeded expectations on all fronts. Compound is now the leading DeFi protocol both in terms of Total Value Locked and in terms of COMP’s marketcap relative to other DeFi tokens. COMP was recently listed on Coinbase — the leading US cryptocurrency exchange and has seen strong interest from dozens of other exchanges including futures platforms like FTX. Compound’s new governance system is well underway, with close to close to 10 proposals being passed since it’s launch. What’s unique about COMP’s governance model is that tokenholders can delegate their tokens to an address of their choice. Only those who hold more than 1% of the supply can make new proposals. Besides earning interest on your crypto assets, which is a straightforward process of depositing crypto assets on the platform and receiving cTokens, you can also borrow crypto on Compound. Borrowing crypto assets has the added step of making sure the value of your collateral stays above a minimum amount relative to your loan. Compound and DeFi more broadly wants to help people have more access and control over the money they earn and save. While the project has had its criticisms, the long-term goal of Compound has always been to become fully decentralized over time. The Compound team currently manages the protocol, but they plan to eventually transfer all authority over to a Decentralized Autonomous Organization (DAO) governed by the Compound community.

DEXs: Decentralized exchanges allow users to switch their assets without the need to transfer custody of basic collateral. DEXs aim to provide unreliable and interoperable trading across a wide range of trading pairs.

Kyber


Source: https://images.app.goo.gl/sFCUhrgVwvs9ZJEP6
Kyber is a blockchain-based liquidity protocol that allows decentralized token swaps to be integrated into any application, enabling value exchange to be performed seamlessly between all parties in the ecosystem. Using this protocol, developers can build innovative payment flows and applications, including instant token swap services, ERC20 payments, and financial DApps helping to build a world where any token is usable anywhere. Kyber’s ecosystem is growing rapidly. In about a month, the team got an investment and partnered with some of the best projects. ParaFi Capital, a blockchain-focused investment company, has made a strategic purchase of KNC codes. The company will assist the DeFi project by qualifying new clients and improving professional market manufacture. The project’s recent partnerships seem impressive. Includes Chainlink, Chicago DeFi Alliance, and Digifox Wallet.
An important DeFi integration was also made with MakerDAO. KNC can now be used as a DAI warranty. The project has reached a milestone worth $ 1 billion of total turnover since its inception. More importantly, volume on an annual basis is moving and accelerating from $ 70 million in the first year to more than $ 600 million in 2020. Recently five million KNC (about 2.4% of total supply) were burned, improving Kyber’s supply and demand ratio. In July, the Kyber network witnessed a Katalyst upgrade that will improve governance, signature, delegation and structural improvements.
When Katalyst hits the main network, users will be able to either vote directly or delegate tokens to shareholder groups led by either companies like Stake Capital or community members. The KNC used to vote is burned, and in turn, voters get ETH as a reward. This setting creates a model for staking an uncommon contraction for the Kyber network. KyberDAO will facilitate chain governance, like many other projects based on Ethereum. An interesting partnership with xToken has been set up to help less-participating users stake out via xKNC. xKNC automatically makes specific voting decisions, making it easier for users to join and enjoy the return. The pool was created to draw BTC to Curve. Users who do this are eligible for returns in SNX, REN, CRV, and BAL. The more BTC lock on Synthetix, the more liquid it becomes, and the more attractive it is for traders. The project plans to continue expanding its products and move towards more decentralization. Synthetix futures are scheduled to appear on the exchange within a few months. The initial leverage is expected to be 10 to 20 times. The team aims to neglect its central oracle and replace it with one from Chainlink during the second stage of the migration. This will significantly increase the decentralization and flexibility of the platform. For following the project:

Derivatives: In traditional finance, a derivative represents a contract where the value is derived from an agreement based on the performance of an underlying asset. There are four main types of derivative contracts: futures, forwards, options, and swaps.

Synthetix

Source: https://images.app.goo.gl/1UsxQ7a3M5veb5sC7
Synthetix is a decentralized artificial asset issuance protocol based on Ethereum. These synthetic assets are guaranteed by the Synthetix Network (SNX) code which enables, upon conclusion of the contract, the release of Synths. This combined collateral model allows users to make transfers between Compound directly with the smart contract, avoiding the need for counterparties. This mechanism solves DEX’s liquidity and sliding issues. Synthetix currently supports artificial banknotes, cryptocurrencies (long and short) and commodities.
SNX holders are encouraged to share their tokens as part of their proportionate percentage of activity fees are paid on Synthetix.Exchange, based on their contribution to the network. It contains three DApp applications for trading, signature and analysis: Exchange (Synths at no cost). Mintr (SNX lock for tuning and fee collection). Synthetix Network Token is a great platform in the ethereum ecosystem that leverages blockchain technology to help bridge the gap between the often mysterious cryptocurrency world and the more realistic world of traditional assets. That is, on the Synthetix network, there are Synths, which are artificial assets that provide exposure to assets such as gold, bitcoin, US dollars, and various stocks such as Tesla (NASDAQ: TSLA) and Apple (NASDAQ: AAPL). The whole idea of these artificial assets is to create shared assets where users benefit from exposure to the assets, without actually owning the asset.
It is a very unique idea, and a promising project in the ethereum landscape. Since it helps bridge the gap between cryptocurrencies and traditional assets, it creates a level of familiarity and value that is often lost in the assets of other digital currencies. This will make Synthetix take his seat in the next stage. On June 15, BitGo announced support for SNX and on June 19, Synthetix announced via blog post that Synthetix, Curve, and Ren “collaborated to launch a new stimulus group to provide liquidity for premium bitcoin on Ethereum”, and said the goal was to “create the most liquid Ethereum — the BTC-based suite available to provide traders with the lowest slippage” In trade between sBTC, renBTC and WBTC. “ For following the project:

Wallets: Wallets are a crucial gateway for interacting with DeFi products. While they commonly vary in their underlying product and asset support, across the board we’ve seen drastic improvements in usability and access thanks to the growing DeFi narrative.

Argent


Source: https://images.app.goo.gl/mYPaWecFfwRqnUTx6
It is the startup for consumer game-changing financial technology, which makes decentralized web access safer and easier. The company has built a smart and easy-to-use mobile wallet for Ethereum, which gives users the ability to easily retrieve their encrypted currencies on the go.
Argent Benefits:
  • Only you control your assets
  • Explore DeFi with one click
  • Easily retrieve and close your wallet
  • The wallet pays gas for in-app features, for example Compound and Maker
The Argent crypto wallet simplifies the process without sacrificing security. It is a type of wallet that allows you to keep cryptographic keys while keeping things simple. The Argent wallet is secured by something called the Guardians. If you lose your phone (and your Argent wallet), just contact your guardians to confirm your identity. Then you can get all your money back on another device. It is a simple and intuitive method that can make cryptocurrency manipulation easier to do without experience. Argent is focused on the Ethereum blockchain and plans to support everything Ethereum has to offer. Of course, you can send and receive ETH. The startup wants to hide the complexity on this front, as it covers transaction fees (gas) for you and gives you usernames. This way, you don’t have to set a transaction fee to make sure it expires. Insurance cooperative Nexus Mutual and Argent Portfolio Provider are planning to offer a range of smart and insurance contracts to keep Argent user money safe from hackers. First, the smart contract is designed to prevent thieves from draining the wallet by temporarily freezing transfers above the daily spending limit for addresses not listed in the user’s whitelist. The user has 24 hours to cancel the frozen transfer — very similar to the bank’s intervention and prevent fraud on the card or similar suspicious activities in the account. By contrast, the default coding state is closer to criticism: once it disappears, it disappears. “We are thinking not only of crypto users but also new users — so the ultimate goal is to duplicate what they get from their bank,” said Itamar Lisuis, one of the founders of Argent. For following the project:

Asset Management: With such a vast amount of DeFi products, it’s crucial that tools are in place to better track and manage assets. In line with the permissionless nature of the wider DeFi ecosystem, these assets management projects provide users with the ability to seamlessly track their balances across various tokens, products and services in an intuitive fashion.

InstaDapp

Source: https://images.app.goo.gl/VP9Xwih6VQ1Zmv2E9
It is a smart wallet for DeFi that allows users to seamlessly manage multiple DeFi applications to maximize returns across different protocols in a fraction of the time. With InstaDapp, users can take advantage of industry-leading projects like Compound, MakerDAO and Uniswap in one easy-to-use portal. Instadapp currently supports dapps MakerDAO and Compound DeFi, allowing users to add collateral, borrow, redeem and redeem their collateral on each dapp, as well as refinance debt positions between the two. In addition to its ease of use, InstaDapp also adds additional benefits and use cases for supported projects that are not already supported. The project focuses on making DeFi easier for non-technical users by maintaining a decentralized spirit while stripping many of the confusing terms that many products bring with them.
InstaDapp has launched a one-click and one-transaction solution that allows users to quadruple the COMP Codes they can earn from using quadruple borrowing and lending. A good timing feature for sure, but this kind of simplification is exactly why Instadapp was created. Its goal is to create a simple interface into multiple DeFi applications running on the Ethereum Blockchain and then automate complex interactions in a way that enables users to maximize their profits while reducing transactions and Ethereum gas charges. To use Instadapp you will need Ethereum wallet and you will also have to create what is called Instadapp smart wallet in which token you want to use. For following the project:

Medium: https://medium.com/instadapp
Github: https://github.com/instadapp
Savings: There are a select few DeFi projects which offer unique and novel ways to earn a return by saving cryptocurrencies. This differs from lending as there is no borrower on the other side of the table.

Dharma

Source: https://images.app.goo.gl/4JhfFNxPfE9oxoqV6
Dharma is an easy-to-use layer above the compound protocol. It introduces new and non-technical users to transaction encryption and allows them to easily borrow or lend in DeFi markets and earn interest in stable currencies. You can start by simply using a debit card. Funds are kept in a non-portfolio portfolio, which constantly earns interest on all of your deposited assets. The value of Dharma’s DeFi lending experience is:
  • Easy entry.
  • Simple wallet.
  • High protection.
  • Depositing and withdrawing banknotes.
Dharma, the prominent DeFi cryptobank bank, has made it extremely easy to bring any Twitter user into the crypto world. Dharma users can send money from the Dharma app by searching for any Twitter handle, setting the required amount, and clicking on one button. The Twitter Dharma Bot account can send a unique notification with a link to download the Dharma mobile app. Senders are encouraged to retweet the notification to ensure that the receiver does not lose it.
To raise money, recipients simply download the Dharma app. After creating a Dharma account, users connect their Twitter account to receive access to the money sent. They can choose to transfer money to US dollars and withdraw to a bank account, or leave DAI in a Dharma account where it will earn interest like all Dharma deposits. The submitted DAI will gain interest even before the receiving user requests it while waiting for the claim. In her ad, Dharma demonstrated a number of ways in which the new social payments feature can be used, including tips for your favorite Twitter personalities, accepting payments for goods or services in a very clear way, charitable donations across borders or transfer payments. The Dharma app is available for both Android and iOS. Dharma and Compound
Dharma generates interest by DAI signing the Compound Protocol. Dharma also appeared in the news recently after the release of a specification outlining a Layer 2 expansion solution allowing the platform to expand to handle current transaction volume 10x, ensuring users can transfer their money quickly even in times of heavy congestion on the Ethereum network. Dharma is developing its “core” and “underwriting” contracts within the company. Underwriting contracts are open source and non-custodian, while each loan contract is closed source. This means that the receiving address contains nodes that interact with a script on a central Dharma server.For following the project:

Insurance: Decentralized insurance protocols allow users to take out policies on smart contracts, funds, or any other cryptocurrencies through pooled funds and reserves.

Nexus Mutual


Source: https://images.app.goo.gl/b7HwB8ifvTXwFhrh6
Nexus Mutual uses blockchain technology to return mutual values to insurance by creating consistent incentives with the smart contract symbol on the Ethereum blockchain. It is built on the Ethchaum blockchain and uses a modular system to aggregate smart Ethereum nodes, allowing to upgrade the system’s logical components without affecting other components.
The way Nexus works is members of the mutual association by purchasing NXM codes that allow them to participate in the decentralized independent organization (DAO). All decisions are voted on by members, who are motivated to pay real claims. It sees plenty of opportunities in a gradual transition of Ethereum to Eth 2.0, which is expected to start later this year. Eth 2.0 moves the network from the power-hungry Proof-of-Consensus (PoW) algorithm to Proof-of-Stake (PoS), a way to sign cryptocurrency in order to keep the network afloat. Having a steady return on signature from the Ether (ETH) can be somewhat compared to the way in which insurance companies invest in the real world the premiums they collect.
By setting a strong set of conditions for Nexus Mutual, anyone will be able to bring in and acquire a new form of risk for mutual coverage — assuming that members are willing to share NXM. With this design, the mutual discretion will be able to expand into much broader fields beyond smart contracts. In addition to defining multi-layered term agreements, Nexus Mutual also has some other advantages needed to achieve this visualization. For following the project:

Ethereum JavaScript Libraries: web3.js vs. ethers.js

Web3.js and ethers.js are JavaScript libraries that allow developers to interact with the Ethereum blockchain. They are both great libraries - either library will likely meet the needs of most Ethereum developers. This article is a comparison of web3.js and ethers.js, focusing on their similarities and differences, so that you can better understand the nuances of the libraries. It is written with the intent of educating developers to understand the tradeoffs between the two libraries to be able to make a decision of which library to use for their particular use case. This article includes resources that may be useful for those who are new to blockchain development or programming in general.
TL;DR: Both libraries work. For your use case, one library may be better for you.
