ChainCatcher message, the snapshot shows that Arbitrum has initiated a proposal to open up the permission for deploying the Orbit chain on networks outside of Ethereum, such as the Bitcoin network, Cosmos, etc. In return, the newly established Orbit chain is required to return 10% of its on-chain profits to the Arbitrum ecosystem, with 8% allocated to ArbitrumDAO and 2% to the Developer Association.It is reported that the "Arbitrum Expansion Plan" is a set of tools and services maintained and provided by the Arbitrum Foundation, aimed at enabling developers to deploy and operate a trust-minimized network whose security relies on the security of the Ethereum blockchain.

ChainCatcher news, according to Ember monitoring, six months after stealing assets, the Orbit Chain hacker transferred 4000 ETH to a new address within nearly 1 hour and completed the money laundering through Tornado Cash.

ChainCatcher message, Conduit released a post-mortem analysis report regarding the previous downtime incident of Degen Chain. On May 10, Conduit increased the batch size for Degen and Proof of Play Apex to 10MB to reduce costs, which delayed the time for data to be batch published from these networks to their parent chain. On May 12, this configuration was reverted to fix the batch publishing. This led to reorganizations on both networks, as the batch was published after a 24-hour forced inclusion window. Arbitrum Nitro will insert any inbox messages before any transactions in the batch and replay those transactions using the new timestamps.After the reorganization, nodes returned with corrupted databases due to their depth not being well handled by geth. This required resynchronizing the data directory from genesis. The synchronization time for each network exceeded 40 hours, with a replay rate of about 100M gas/s. Once the nodes were resynchronized, Conduit attempted various transaction replay strategies, although not all transactions could be recovered, as some relied on precise timestamps.After negotiating with each rollup team, Conduit discussed and concurrently tried various strategies to bring the network online and restore the state prior to the reorganization. The Degen Chain network was restored online 54 hours after the outage. The Apex chain of Proof of Play was restored around the same time but became available to the public only after implementing another recovery solution.Conduit stated that it has improved alerts and monitoring for the Orbit chain to cover such situations and is committed to working with Offchain Labs to enhance the observability of all Orbit chain operators. The team will continue to invest in and research mechanisms to better simulate mainnet conditions and transaction payloads in a testing environment. The Degen Chain Explorer is now displaying the latest status of Degen Chain normally.

ChainCatcher news, the game L3 project Sanko GameCorp announced the mainnet launch on platform X. Users can bridge DMT from Arbitrum to Sanko through the native Sanko bridge, and any ERC-20 token on Arbitrum can be bridged to Sanko.Note: Please explore the native applications on the official website, SankoTools, Camelot, and SudoSwap are now live.Last September, Web3 infrastructure provider Caldera announced the launch of its first Arbitrum Orbit chain, with three partners planning to launch production-grade mainnet Orbit chains through Caldera in the coming weeks: Syndr, Sanko GameCorp, and Volatilis Technology.Syndr is a decentralized derivatives exchange with cross-margining, Sanko GameCorp is an online gaming studio, and Volatilis Technology will build a dedicated environment for DeFi to develop open currency markets.

ChainCatcher news, Arbitrum has released a community proposal for a "temperature check on changing the Arbitrum expansion plan to allow new Orbit chains to be deployed on any blockchain." It states that one limitation of the Arbitrum expansion plan is that new Orbit chains must be deployed on chains that derive security from Ethereum. However, in the past few weeks, the Arbitrum Foundation has received requests from Bitcoin, BNB Chain, and Cosmos ecosystem projects that wish to deploy their own Orbit chains on other networks.Therefore, the Arbitrum Foundation is asking the Arbitrum DAO to decide whether the Arbitrum expansion plan should be further expanded to allow new Orbit chains to be deployed on blockchains outside of Ethereum (and its derivatives). If the Arbitrum DAO approves the proposal, the Arbitrum Foundation will be responsible for collecting a 10% share of the profit revenue from the new chains and will ultimately transfer the funds to the Arbitrum DAO treasury and the Arbitrum Protocol Guild. The only requirement to consider before deploying projects on-chain is to check whether the Arbitrum Foundation has deployed a multi-signature to collect revenue sharing. A multi-signature is needed to help the Arbitrum Foundation collect fees and regularly connect them to the Arbitrum DAO treasury.It is reported that the proposal will organize three governance calls, scheduled for April 22 at 18:00 Beijing time, April 27 at 00:00, and May 1 at 04:00. After community discussions, the proposal will undergo a temperature check on Snapshot, with voting options divided into "any blockchain network" and "Ethereum L1 only."

ChainCatcher news, Arbitrum announced the launch of the Arbitrum Orbit expansion program, allowing the launch of Ethereum-based custom Orbit chains (L2 or L3) through a self-service path. Arbitrum stated that under the permissionless profit-sharing model of this program, Orbit chains are entitled to create custom L2 or L3 that settle directly to Ethereum or other Ethereum L2s, such as optimistic rollups, ZK-Rollups, optimiums, and validiums.In addition, the two main requirements for participating in the Arbitrum expansion program are that participants need to give back a portion of their profits to the Arbitrum ecosystem, and the deployed Rollup must exclusively rely on Ethereum or chains secured by Ethereum.
