Block lookup

Enter a block height or a block hash to see the block’s measured facts. Blocks processed by Signal21’s live ingestion are labeled standard or special by fixed, documented rules; older blocks outside the evaluated range are shown as not evaluated. Facts only, no speculation about senders, purposes or meaning. Texts embedded in transactions (including those scrolling on the front page) are third-party content written to the public blockchain by unknown parties, reproduced as data, and are not authored, endorsed or verified by Signal21. The front page’s featured discussion is a curated thread of such texts: each line is attributed to a party only by the coins it spends or by a PGP signature checked against that party’s published key, encrypted messages are described but never decrypted or shown, and the statements are the parties’ own, shown verbatim.
