Fortunately, the chains were all fine. Unfortunately, the centralized explorer was offline.  \n\nPeople were panicking, feeling around in the dark for some kind of light to illuminate their transactions, and scared that the blockchains themselves had failed. \n\nIn this dark hour, those who knew Blockscout and/or other available block explorers were able to quickly find that light.  This was a local data center issue for Etherscan, and the fact that there were additional available explorers proved to be of absolute & vital importance.\n\nWith the help of luminaries like Jesse Pollak and Martin K\u00f6ppelmann, those in need were quickly redirected to Blockscout. Blocks, addresses, tokens and transactions were available to view and search, and for a moment, all was right again with the world.\n\n> PSA: [@BaseScanHQ](https://twitter.com/BaseScanHQ) is down \u2014 but [@base](https://twitter.com/base) is up and there are many great block explorers you can use. recommend you try out [@blockscoutcom](https://twitter.com/blockscoutcom), which also has great support for smart wallet transactions (UserOps). \n\n - [Jesse Pollak](https://twitter.com/jessepollak/status/1775960537089921395)\n\n\n> Good time to check out [@blockscoutcom](https://twitter.com/blockscoutcom) - they made significant improvements in the last couple of months. \n\n- [Martin K\u00f6ppelmann](https://twitter.com/koeppelmann/status/1775985315078975635)\n\n# Open-source block explorers are a vital public good\nJust like we need multiple clients for Ethereum, we need multiple explorers and tooling diversity for the Ethereum ecosystem. If one goes down, the others are there to step in and support.\n\nThis redundancy is vital, but it is not Blockscout's mission. **Our mission is to provide a first-class, open-source, decentralized explorer for all users.** An explorer built by and for the community that can provide everything users, developers, and projects need to successfully explore and develop on a chain.\n\nOver the past year we've been working hard on Blockscout. Thanks to community contributions, we've had the ability to optimize Blockscout for speed while overhauling the frontend for ease of use.  We've introduced tools to make smart contract verification much easier, and added tagging, account functionality, marketplace features and more. \n\nWith your help, we will continue adding tools and features to support Ethereum and the network of L2s and L3s building on top.  \n\n# Open-source explorers support the entire ecosystem\n\nEVM blockchains and L2s including zk rollups and optimistic rollups need open-source explorers and tooling to support: \n- Freely available data\n- Data accuracy checks\n- Redundancy and resiliency \n- Community-driven features, customizations and innovations\n- Transparency\n- Quick, cost-effective implementation, especially for testnets\n- Small chain and niche chain support\n- Consistent multi-chain experience\n- Ongoing, fast feature development\n- Trustlessness and auditability\n\n# Blockscout is a community-driven solution\n\n![Projects](https://2383309224-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-Lq1XoWGmy8zggj_u2fM%2Fuploads%2Fw3dTDLmPyLAPoosi5DRZ%2Fproject-logos.jpg?alt=media&token=20033b6d-ee5e-4d90-a1ce-d5db6752bcb3)\n\nBlockscout has been in production for more than 6 years. We continue to build and improve an open-source explorer used by 600+ chains in the space including most testnets + a hosted [Ethereum mainnet](https://eth.blockscout.com/) and testnet instances provided as public goods. \n\nBlockscout is used by all types of chains to quickly spin up an instance and provide transactional transparency right away for their users. We continue to make strides with our interface, indexing speed and optimization, and your help is vital to continued improvements and development.\n\n# How your funds will be used\n\n![UI](https://2383309224-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-Lq1XoWGmy8zggj_u2fM%2Fuploads%2F6bR1Y370zhW2nECWdpqY%2Fnew-features.jpg?alt=media&token=4b4a2819-c907-474c-bf78-d25cf9a26fa3)\n\nThrough contributions from previous Gitcoin Grants Round we've been able to fully open-source the Blockscout UI, introduce MyAccount, create the DAppscout marketplace and provide ENS support! \n\nNext we are making a concerted push to support all features that closed-source explorers offer and provide additional tools for developers.  These include:\n\n - Ongoing support for Ethereum roadmap items (such as recent support for EIP-4337 and EIP-4844)\n - Additional API development\n - Public tags\n - Advanced statistics\n - CSV export improvements\n - Advanced filtering\n - EVM ecosystem verification app\n - Remix IDE integration\n - More items based on community feedback and feature requests\n\nWe will also work to spread the word about Blockscout, so that more people and projects know there is an alternative explorer that can serve their data and exploration needs. \n\nYou can learn more about additional items we are working on (or to make a suggestion or get involved), please see the [Blockscout Docs](https://docs.blockscout.com). \n\nAs we continue to decentralize the future, the tools and infrastructure supporting decentralization must also follow this pattern. We appreciate your funding to support an open-source, premium block explorer - by and for the community! \n\n## Thank You!", "lastUpdated": 0, "projectGithub": "blockscout", "projectTwitter": "blockscoutcom"}, "recipient": "0x242ba6d68FfEb4a098B591B32d370F973FF882B7"}}
