Ethereum 2.0 to be implemented as early as this year; BM releases draft proposal for EOS community governance | Public Chain Weekly Report

According to incomplete statistics from ChainCatcher, between March 8 and 14, there were 15 significant news events in the public chain infrastructure sector, involving public chains such as Ethereum, aelf, EOS, Casper, Solana, Cosmos, and Avalanche.

1. Contentos public chain is about to launch customizable content NFTs

On March 9, the content public chain Contentos (COS) will launch the creator NFT feature on the blockchain video platform COS.TV this week, allowing content creators to customize cross-chain NFTs, tokenizing audio and video copyrights, and supporting token claims in multiple formats including BSC BEP-20. The first batch of invited influencers has already begun testing.

It is reported that Contentos (COS) has received strategic investment from Binance Labs, the ecological fund under Binance. Contentos aims to create the world's largest public chain for digital content, unifying the value of content globally.

2. Wanchain BTC-ETH cross-chain bridge is now live, featuring BTC direct cross and collateral multi-chain sharing functions
On March 9, Wanchain's multi-chain interoperability mechanism went live on the mainnet, officially launching the BTC-ETH direct cross function. This upgrade to the cross-chain mechanism involves an upgrade to the BTC cross-chain contract. The original BTC cross-chain token will be displayed as wanOBTC in the wallet interface, while the new BTC cross-chain token will be displayed as wanBTC. Therefore, users who originally held BTC cross-chain tokens need to manually convert wanOBTC to wanBTC through WanSwap. Wanchain's bidirectional interoperability mechanism has two main features: collateral multi-chain sharing and direct BTC cross.

3. Privacy public chain Secret Network launches native DeFi ecosystem token SEFI, with 10% of initial supply to be distributed to the community
On March 9, the privacy public chain Secret Network (SCRT) announced the launch of the native DeFi ecosystem token SEFI, which can be obtained by participating in SCRT staking, interacting with Secret Bridge (bridge mining), and using the decentralized exchange SecretSwap. SEFI will initially be used for governance of SecretSwap, with 10% of SEFI tokens distributed after the genesis, and the remaining 90% will be distributed to SecretSwap users over four years, with rewards halving each year. 10% of the total supply of SEFI will be distributed to the community, with the snapshot date being any date before the end of March. The specific distribution method is as follows: 25% allocated to certain Ethereum DeFi communities on Secret Bridge, communities with locked token amounts exceeding $10 million can receive 25% of the share, and the remaining 75% will be allocated to SCRT stakers (35%), SecretSwap LPs (25%), and Secret Network Ethereum bridge users (15%).

Secret Network is a privacy-based blockchain protocol that allows decentralized applications to use encrypted data that will not be leaked, enabling developers to build new types of powerful, permissionless, privacy-preserving applications. Its proof-of-stake network is used for staking and managing network fees.

4. Vitalik Buterin: A fully EVM-compatible Rollup is expected to be launched in about a month
On March 10, Ethereum co-founder Vitalik Buterin stated in a recent podcast that Eth2 developers are working on the Ethereum chain merge and believe that second-layer solutions can support the Ethereum network before shard development is completed. He said, "Rollups will appear soon. We are fully confident, and when more scalability is needed, sharding has been ready for a long time."
Additionally, Vitalik expects that "in about a month," a fully Ethereum Virtual Machine (EVM)-compatible Rollup will be launched. He also mentioned that the Ethereum network is about to scale 100 times and predicts that Optimism will release its second-layer solution in the coming weeks.

5. OKExChain collaborates with 20 testnet projects to launch public testing, airdropping 2000 OKT
From March 11, 20:00 to March 16, 20:00, OKExChain will collaborate with 20 testnet projects to invite community users for large-scale public testing, providing 2000 OKT as rewards for participation.
According to the rules, users must use OKT test tokens to complete any 3 testing tasks on OKExChain projects. The first 10,000 users who complete the tasks and fill out the reward form will receive 0.2 OKT airdrop, which will be completed within 15 working days after the EVM deployment mainnet.

6. aelf announces the launch of the Centralized Asset Management System (CAM)
On March 11, the decentralized cloud computing blockchain network aelf officially announced the launch of the Centralized Asset Management System (CAM). The official statement indicates that aelf CAM is essentially a smart contract on the aelf blockchain. It creates a master address for any given exchange, which will be managed by the CAM contract rather than the exchange itself or anyone else. Under this system, exchanges can only perform basic transactions, cannot control user assets, and cannot vote, etc. Users will receive a CAM virtual address to check balances and protect asset security.

7. ConsenSys: Ethereum has taken a significant step towards upgrading to PoS, expected to be achieved as early as this year

On March 12, Ethereum technology company ConsenSys published an article stating that Ethereum core developer Mikhail has submitted a GitHub pull request for the ETH2.0 specification to create a version of the Ethereum mainnet driven by the beacon chain's PoS consensus, marking a significant step for Ethereum towards the PoS consensus mechanism.

At the same time, ConsenSys also stated that second-layer scaling solutions such as Rollups are developing faster than the ETH 2.0 technical community had anticipated and have already become a key part of the Ethereum 2.0 roadmap, which means that the transition from PoW to PoS consensus mechanism for Ethereum may happen sooner, potentially as early as this year.

8. Digital identity solution Civic to integrate with Solana and launch mobile DeFi entry application

On March 12, digital identity solution Civic announced a technical integration with the high-performance public chain Solana, adding identity elements to the Solana ecosystem. Additionally, Civic will establish a mobile application-based DeFi entry on Solana to provide a user-friendly experience. Currently, Civic's mobile application is based on the Ethereum network. Civic uses the open-source identity verification ecosystem from Identity.com to support its products, which recently announced integration with Solana, focusing on improving decentralized identity.

9. Public chain project Taraxa has completed its public offering, with 504 actual subscribers

On March 12, the public chain project Taraxa successfully completed its public offering on the Tokensoft platform this morning, with approximately 13,000 online subscription participants and 504 actual subscribers. Additionally, Taraxa plans to launch its planned listing soon.

10. Avalanche expects to complete its indexing system in May, at which point Blocknet will migrate to Avalanche
On March 12, the decentralized blockchain network Avalanche (AVAX) officially announced that the Blocknet protocol plans to migrate to Avalanche to fully focus on cross-chain product development. According to official disclosures, Avalanche expects to complete its indexing system in May, at which point Blocknet will begin migrating to the Avalanche subnet. Blocknet will expand the capabilities of the Avalanche subnet through a decentralized indexing system, enabling DApps to use Avalanche contracts and transactions in a trustless manner on any other blockchain.

11. BM releases draft proposal for EOS community governance

On March 13, EOS founder BM (Daniel Larimer) tweeted that he has released a draft proposal for EOS community governance. The draft outlines the process for reviewing and appointing individuals to control EOS token distribution, as well as the future direction of EOS.

According to the draft, to become a community member, one must request (or provide) an invitation from an existing member, confirmed by two other members, and finally, the new member must receive approval from at least one elected official. Additionally, every time the community grows by 10%, an election will be automatically triggered, and no new members can officially join until the election process is completed. This reduces the risk of elections being subject to Sybil attacks.

12. Cosmos community releases new proposal to enable IBC transfers

On March 13, the cross-chain project Cosmos (ATOM) community initiated a proposal to enable IBC transfers, allowing the use of the ICS20 standard on Cosmos Hub to transfer and receive assets. The proposal voting deadline is March 27. If the proposal is approved, ATOM will be used on IBC-connected Zones. IBC is a cross-chain communication protocol designed around the Cosmos network and Tendermint consensus, facilitating bidirectional communication for value transfer across protocols between Hub and Zones.

13. Ethereum core developer Eric Conner is considering creating a new EIP to propose reducing block rewards from 2 ETH to 1 ETH

On March 13, Ethereum core developer Eric Conner tweeted that "to align with Ethereum's commitment to the minimum necessary issuance, I have begun analyzing the fees we pay for security (consistent with the analysis of EIP-1234), and I am considering creating an EIP to reduce the block reward from 2 ETH to 1 ETH." EIP-1234 previously proposed reducing block rewards and delaying the difficulty bomb.

Additionally, on March 12, a miner proposed EIP-3368, suggesting to increase the current block reward of the Ethereum network from 2 ETH to 3 ETH, and then gradually decrease it in each block until it reaches a reward of 1 ETH per block after 8,000,000 blocks (approximately 2 years).

14. Public chain Elrond partners with on-chain incentive protocol DAFI Protocol

On March 14, DAFI Protocol partnered with the public chain Elrond. After the collaboration, Elrond will introduce DAFI's on-chain incentive program into the mainnet ecosystem, utilizing its algorithmic model (non-overinflationary incentive method) to improve the economic model and achieve long-term incentives for users.

15. Harmony and Reef Finance establish a partnership
On March 14, the high-performance public chain Harmony announced a partnership with the cross-chain DeFi operating system Reef Finance in the Polkadot ecosystem. Users on Harmony can use DeFi applications through the Reef platform. Users and developers can also utilize Reef's smart liquidity aggregator and AI-based yield engine recommendation features.
