ChainCatcher message, BNB Beacon Chain has released the mainnet Sunset upgrade announcement. The upgrade hard fork is expected to occur on April 15, 2024. Full node operators on the mainnet must upgrade to v0.10.20 before April 15. BNB/BEP2 asset holders will transfer their assets from BC to BSC.

ChainCatcher news, according to official sources, Immutable has announced that Immutable zkEVM has completed the Shanghai hard fork upgrade, with no downtime occurring during the upgrade.Immutable zkEVM, supported by Polygon, will continue to receive Ethereum-level security and the best infrastructure support, allowing all developers to thrive. It is reported that Immutable currently supports Solidity 0.8.20 and Open Zeppelin v5.0, and RPC node operators can now deploy the latest immutable/go-ethereum Docker image to stay in sync with the network.

According to ChainCatcher news, Polygon has announced the completion of the Napoli hard fork upgrade, making Polygon PoS the first chain to activate the Rollup Improvement Proposal (RIP) using RIP-7212, providing new precompiled support for the secp256r1 curve and making progress in interoperability with mainstream technologies.This upgrade is also consistent with Ethereum's recent Dencun hard fork improvements, enhancing block space efficiency, limiting the range of self-destruct opcodes, and reducing the overhead of memory copy techniques. Developed by the RollCall Working Group, RIP-7212 facilitates collaboration between L2 solutions to strengthen Ethereum's scalability and innovation efforts, enhancing the user experience.

ChainCatcher news, according to official information, Klaytn V1.12.0 has been released. This version includes two different hard forks: the first is equivalent to the Ethereum Cancun hard fork functionality, and the second is an optional hard fork that enables on-chain randomness through Randao. The hard fork will take place on the Baobab testnet at block height 135456000, expected to occur on December 19 at 9 AM.The official reminder states that this version includes a hard fork upgrade that introduces backward-incompatible changes. All Baobab nodes must upgrade to V1.12.0 or higher before the target block height. The hard fork block height for the Cypress mainnet will be determined in the next version.

ChainCatcher message, BNB Chain announced, "Zhang Heng" upgrade is expected to take place at block height 328,088,888 on July 19. Full node operators on the mainnet must switch their software version to v0.10.16 before July 19.An important feature change in this upgrade is the introduction of BEP-225, which allows for on-chain asset reconciliation on the BNB Beacon Chain to enhance security. Each block will track changes in user balances and coordinate to identify issues. When a coordination error occurs, the blockchain will stop generating new blocks. (Source link）

ChainCatcher message, BNB Chain will undergo a Luban hard fork upgrade at block height 29,020,050, expected to take place on June 12, Beijing time.The Luban hard fork includes three BEPs: BEP-126, BEP-174, and BEP-221. Validators and full node operators on the mainnet should switch their software version to v1.2.4 before June 12, 2023. (source link)

ChainCatcher message, Coin Dance page shows that the Bitcoin Cash (BCH) mainnet has successfully executed a hard fork upgrade as planned and activated new rules. It is reported that this upgrade includes the introduction of the token issuance feature CashTokens and support for smart contracts, allowing developers to build DApps on BCH. (Source link)

ChainCatcher message, Ethereum programming language Solidity releases Solidity compiler version 0.8.20. The latest version includes a series of improvements to the via-IR pipeline and enhances the list of events exposed in the contract ABI, supporting the Shanghai hard fork upgrade.

ChainCatcher news, Coinbase Layer2 network Base has completed the Base Goerli Regolith hard fork. This hard fork enables changes to the timestamp-based configuration of the OP Stack's Rollup nodes and execution engine, aimed at making Base more secure and reliable. After the upgrade, deposit transactions now include random numbers for easier tracking. (source link)

ChainCatcher news, according to the official announcement, the BNB Beacon Chain is expected to undergo the scheduled Barral hard fork upgrade at block height 310,182,000. Based on the current block generation speed, the hard fork is expected to occur on April 21 at 15:00 Beijing time. Full node operators on the mainnet must switch their software version to v0.10.10 before April 21.In this upgrade, BEP171 will introduce several security enhancements for the cross-chain bridging between the BNB Beacon Chain and the BNB Smart Chain. To further mitigate the widespread impact of potential issues in the cross-chain module, BEP171 proposes the following improvements: 1. Upgrade IAVL proof verification to the ICS23 specification. 2. Apply timer locks for large fund cross-chain transfer applications. 3. Cross-chain channels can be automatically paused through forged proof detection. 4. In emergencies, any validator can pause the cross-chain channel. (source link)
