ChainCatcher news, zkSync Developers posted on social media that the zkSync Era Sepolia testnet is expected to fully recover in the next few hours. The v24 mainnet upgrade will be postponed until later next week to give the team more time to assess the stability of the testnet. A precise release date will be provided when the team is confident in its stability.zkSync Developers stated that there were two issues affecting the testnet (which have now been resolved): First, due to instability in the eth_sender service (responsible for submitting transactions to the L1 zkSync smart contract), there were no L1 submission blocks for about 1 day. This was caused by the gas market on Sepolia being very different due to Blob pricing. Second, there were no proofs submitted for more than two days, leading to withdrawal delays. This was caused by logical differences between the VM inside the circuit (used for generating proofs) and the VM outside the circuit (server-side VM that executes immediately when submitting transactions).

ChainCatcher message, zkSync Developers posted on X platform last night stating that the team is investigating a persistent issue on the zkSync Sepolia testnet. During the ongoing investigation, withdrawing Sepolia funds from the zkSync Era Sepolia testnet is unavailable. This investigation (and its results) may affect the mainnet v24 release scheduled for next Monday.At around 3 AM today, zkSync Developers released an update stating that the investigation is still ongoing and will continue until tomorrow, when more updates will be provided.

ChainCatcher news, according to The Block, OP Labs announced that it has launched Fault Proof on the OP Sepolia testnet, stating: "The open-source, fully functional Fault Proof is now live on OP Sepolia. Through permissionless validation, anyone can participate in the system without an allowlist."It is reported that Fault Proof serves as a security mechanism for Ethereum L2 networks, allowing users to challenge potentially fraudulent or incorrect transactions. They are crucial for ensuring that off-chain transaction processing is not manipulated.

ChainCatcher news, OP Labs announced on social media that the OP Sepolia testnet will upgrade on March 19 to support a fully functional OP Stack fault-proof version.It is reported that this upgrade will affect cross-chain bridges, CEX, and custom solutions using withdrawals.

ChainCatcher news, the blockchain platform Lisk announced on social media that the Lisk Sepolia testnet is now live.Previously, on January 24, the blockchain platform Lisk released its 2024 development roadmap, planning to launch the Lisk L2 testnet in the first quarter of 2024, connecting to the Ethereum Sepolia testnet to provide a testing platform for developers.

ChainCatcher news, the Ethereum Dencun upgrade has been launched on the Sepolia testnet. It is reported that Sepolia is the second of the three testnets for the Dencun upgrade.Earlier this month, Dencun was launched on the Goerli testnet, but initially failed to finalize.In addition, Dencun will go live on its final Ethereum testnet, Holesky, on February 7. After that, developers will sign the date for activating Dencun on the main blockchain. The testnet replicates the main blockchain and allows developers to make any changes to the protocol or its decentralized applications in a low-risk environment.

ChainCatcher news, Circle announced that it is expanding support for USDC and EURC across multiple Sepolia test networks to better serve developers building on the Circle stablecoin protocol and platform services.Specific changes:USDC will provide new Sepolia test network addresses for Arbitrum, Base, Ethereum, and OP.EURC will provide a new Sepolia test network address for Ethereum.CCTP will provide new Sepolia test network addresses for Arbitrum, Base, Ethereum, and OP. After the migration, the proof API will no longer support Goerli.The faucet will no longer support USDC and EURC on the Goerli test network. Instead, you will be able to select and receive USDC and EURC on the Sepolia test network.Circle Mint deposit addresses created on Goerli will be cleared. Sending USDC or EURC to a cleared address will result in the loss of funds in the Circle Mint sandbox. Any historical transfers and existing balances will remain unchanged.

ChainCatcher news, Layer2 network Base announced on platform X that it has successfully completed the Canyon hard fork on the Goerli and Sepolia testnets. It is reported that Canyon is the next major network upgrade following the Regolith version of the OP Stack. The purpose of the upgrade is to: reduce the volatility of base fees, modify the way the network handles closed channels to improve reliability, allow access to common contracts (create2deployer) across all OP networks, and increase support for Shanghai and Capella.

ChainCatcher message, Ethereum core developer Tim Beiko summarized the latest Ethereum core developer execution meeting (ACDE), where the latest developments of the Dencun development network were discussed, as well as the roadmap for Verkle Trie and State Expiry.Tim Beiko also stated that the Cancun upgrade fork will be tested in the order of Holesky, Goerli, and Sepolia testnets, with the next ACDE scheduled for September 14 at 22:00 Beijing time.

ChainCatcher news, Layer2 solution Scroll announces the launch of the Scroll Beta testnet for developers and users on the Sepolia testnet. New features or improvements include zkEVM upgrades, bridge upgrades, and infrastructure upgrades.Among them, in terms of zkEVM upgrades, EVM compatibility has been improved through precompiled upgrades, efficient on-chain verification through proof compression and aggregation, and enhanced circuit integrity; in terms of bridge upgrades, gas costs can be reduced by up to 50%, and a trustless message relaying feature has been introduced between L1 and L2, eliminating the reliance on trusted relayers; in terms of infrastructure upgrades, the EIP-2718 transaction type L1MessageTx has been introduced for trustless messaging, freeing it from trusted centralized relayers. Additionally, a simplified circuit capacity checker prevents proof overflow and enhances coordinator functionality.Scroll states that so far, over 100 projects have integrated with Scroll, and more projects are in the process of integration. The Scroll testnet on Sepolia will run alongside the future mainnet as a primary testing platform for users and developers. Scroll Goerli will cease to be used after the mainnet launch.

ChainCatcher news reports that according to the latest official announcement, the core developers of the Ethereum blockchain plan to conduct the Shanghai+Capella upgrade on the Sepolia test network on February 28 at epoch 56832. Shanghai+Capella, also known as Shapella, aims to enable ETH withdrawals from network validators, a feature that was not enabled during the network's transition to PoS consensus ("the Merge").This upgrade combines changes to both the execution layer (Shanghai) and the consensus layer (Capella). In order to complete the final upgrade in March, developers plan to conduct multiple phases of public testing. The upcoming release on Sepolia is the second public testnet for the deployment upgrade.Earlier this month, Shapella was tested on the Zhejiang testnet. After deploying Shapella to the Sepolia testnet, developers expect to transition to the Goerli testnet for the final phase of testing before the mainnet release in early March.Previously, ChainCatcher reported that the Ethereum Foundation stated in a recently published article that the Shanghai+Capella (Shapella) mainnet upgrade is entering its final pre-release sequence—public testnet. Shapella includes many features, but the most important for stakers and the consensus layer is the support for withdrawals. Exiting validators can withdraw their full balance, while active validators with a balance exceeding 32 ETH can make partial withdrawals. Additionally, the first long-standing public testnet, Sepolia, is scheduled for an upgrade on February 28. (source link)
