ChainCatcher news, according to Cointelegraph, Brazil is integrating decentralized finance (DeFi) into its ongoing experiments to develop a "synthetic" central bank digital currency (CBDC) called Drex, which was previously known as the digital Brazilian real.On October 3, Brazilian Central Bank President Roberto Campos Neto emphasized the country's need for a multidimensional CBDC, which aims to address the "trilemma" of decentralization, privacy, and programmability—challenges that traditional markets face when trying to solve these issues simultaneously.

ChainCatcher message, BNB Chain posted on X that the Greenfield network is currently facing compatibility issues with the MetaMask browser extension, affecting certain functionalities including bucket creation on Dcellar.This issue stems from the recent upgrade of the middleware library in the MetaMask extension to the latest version, which implemented stricter EIP712 signature verification rules. The BNB Chain team is actively developing a hotfix to address this issue, with a fix expected to be released on September 23.

ChainCatcher news, Layer1 blockchain Sei announced the upcoming launch of the Sei V2 upgrade, becoming a parallelized EVM blockchain. New features include backward compatibility for EVM smart contracts, reusability of widely used applications and tools (such as MetaMask), optimistic parallelization, SeiDB (improvements to the storage layer), and interoperability with existing chains (allowing seamless combinations between EVM and any other execution environment supported by Sei).Sei stated that Sei V2 will provide a throughput of 28,300 batch transactions per second, along with a block time of 390 milliseconds and finality of 390 milliseconds. The major upgrade of Sei is currently nearing code completion. After the audit is completed, this upgrade will be released on the public testnet in the first quarter of 2024 and will be deployed to the mainnet in the first half of 2024.

ChainCatcher news, Layer 1 blockchain Ziliqa announced that the mainnet upgrade enabling EVM compatibility has been successfully deployed, and the Ethereum Virtual Machine (EVM) is now live on the mainnet. The network is currently able to process transactions normally, and exchanges have also resumed ZIL deposits and withdrawals.According to the crypto data platform RootData, Ziliqa is a public blockchain with a sharding architecture designed to address scalability limitations present in other blockchains.

ChainCatcher news, Layer1 blockchain Zilliqa announced that as part of the update V9.0.0, it will soon implement EVM compatibility on the mainnet, opening the network to EVM DApps. This network upgrade will begin deployment on April 25 at 16:00, during which the Zilliqa network will experience a 24-hour downtime, during which the network will not process any transactions. It is recommended to suspend mainnet deposit and withdrawal activities during the network upgrade.It is reported that this network will increase support for DApps written in Solidity and other EVM-compatible languages, while also allowing users to transfer ZIL using EVM wallets such as MetaMask. Additionally, developers can try using user-friendly development tools like Hardhat and Truffle to deploy EVM smart contracts on the Zilliqa mainnet. (Source link)

ChainCatcher news, the one-stop Web3.0 security development environment and middleware engine Hamster has announced comprehensive support and compatibility for the Move-based Sui network. As of now, Hamster has successfully completed the automated pipeline invocation of Sui contract templates based on the Move language and has opened a one-stop node deployment RPC service for the Sui network. With this, developers within the Sui ecosystem can modularize, toolize, and streamline their development processes, allowing for quick onboarding and integration into the ecosystem.It is reported that as a one-stop developer platform infrastructure, Hamster's comprehensive integration and compatibility with the Sui network will significantly lower the development threshold for developers entering the Sui network and improve development efficiency. In addition, multiple Move language contract templates based on the Sui ecosystem's DeFi, NFT, and other tracks are currently being iterated and updated. (Source link)

ChainCatcher news, according to CoinDesk, BNB Chain's Growth Director Alvin Kan announced its technical roadmap, stating that the overall goal for 2023 is the new L2 infrastructure zkBNB and the EVM compatibility and mainnet launch of BNB Greenfield (blockchain-based Web3 infrastructure).As part of the 2023 roadmap, BNB Chain indicated that its goal is to increase the number of validators from 29 to over 100. The blockchain plans to raise its throughput from a 140 million gas limit and 2200 TPS to a 300 million gas limit and 5000 TPS. (source link)

Chain Catcher News: At the 8th Global Blockchain Summit hosted by Wanxiang Blockchain Lab, Filecoin founder Juan Benet delivered a speech titled "Overall Planning of Filecoin," in which he stated that the future overall planning of Filecoin is divided into three phases: 1. Building the world's largest decentralized storage network; 2. Uploading various human data and developing large-scale data loading pipelines; 3. Combining data and computation.It is reported that Filecoin is currently in the second phase, working towards the goals of this phase through several major projects. At the beginning of this year, the total data usage across the network was approximately 20PB, which has now risen to 185PB. Furthermore, in the third phase, Filecoin plans to introduce programmability for the Filecoin Virtual Machine in the first quarter of next year, launching a series of testnets that will allow many teams to build based on the testnets. Currently, 25 teams are already developing on the testnet. Over 2000 new projects are currently being developed or have been deployed on Filecoin, and the number of projects continues to grow.Filecoin is also building compatibility with the Ethereum Virtual Machine, meaning that developers can directly call contracts from Ethereum's FVM without any changes, at most just altering the deployment path for deployment. Another very important dimension for Filecoin is the creation of cross-chain bridges that connect with other blockchains.
