ECHO ("Long Live Our Opinion") is an embeddable interchain social infrastructure project that is fully on-chain and decentralized. It is built as the first decentralized social engagement protocol on Arweave, aiming to provide the fundamental infrastructure for Web3 social by offering a comment widget that any Web3 website can deploy, with data stored permanently and immutably. Users authenticate via a decentralized wallet, allowing them to sign and upload data to Arweave with or without a front-end interface, enabling permissionless and censorship-resistant commenting.
