They provide transparency for transaction, block, address, and contract information, as well as analytical insights into transfers, block times, gas prices, and accounts. They display essential context for additional project data, token information, and related tags.\n\nBlock explorers also support blockchain developers through API access, contract verification, and contract interaction tools. For Layer 2s, they serve not only the L2 transaction data but also provide views of the underlying L1 data so that users can get the complete picture as batches travel between layers.\n\nBlock explorers are integral infrastructure for a decentralized ecosystem. At Blockscout, we build an open-source explorer that can be used by all EVM chains. Chains are free to fork Blockscout, customize it as they see fit, and use it to support their network. Blockscout supports the Arbitrum ecosystem and will use funds from this grant to continue improving our explorer for Arbitrum-based chains.\n\n# Open-source block explorers are a vital public good\nJust as we need multiple clients for Ethereum, we need multiple explorers and tooling diversity for the Ethereum and rollup ecosystem. If (or when) an explorer is down, others are there to step in and support.\n\nThis redundancy is important, but it is not Blockscout's sole mission. Our mission is to provide a first-class, open-source, decentralized explorer for all users\u2014an 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 optimized Blockscout for speed while overhauling the front-end 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\nFor this round we will be focused on improving tooling and support for Arbitrum-based explorers, specifically chains using the Arbitrum Orbit framework. We currently support Arbitrum networks including: \n\n- [Arbitrum One](https://arbitrum.blockscout.com/)\n- [Arbitrum Sepolia](https://arbitrum-sepolia.blockscout.com/)\n- [Arbitrum Nova](https://arbitrum-nova.blockscout.com/)\n\nWe will continue adding features for Arbitrum-based chains including: \n - Improved smart contract verification tooling\n - Additional API development\n - Public tags development\n - Advanced statistics\n - Advanced filtering\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 within the Arbitrum ecosystem.\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"}}
