peck.network is a network of nodes that do real work — starting with uptime checks — sign every result, and anchor each UTC day as a Merkle root on Bitcoin. Anyone can verify any claim against the chain. Trust no one — check it yourself.
The same primitive — a node does a unit of work, signs it, and the day's work is anchored on-chain — generalizes from "is this URL up" to any verifiable, paid task.
Each node performs a check with full timing, the server's TLS fingerprint and a body hash — artifacts you could only have by actually doing it.
Every result is signed with the node's secp256k1 key. The record can't be altered after the fact, and you know which node produced it.
Each UTC day, every signed result becomes a leaf in a Merkle tree whose root is written to an OP_RETURN on Bitcoin mainnet.
A proof bundle is the signed result, the Merkle path to the day's root, and the anchor transaction. A standalone script verifies all of it with no trust in our servers — the signature, that the leaf is in the tree, and that the root is in a mined Bitcoin OP_RETURN.
Re-implemented from spec — it imports nothing from this network. Block-inclusion is checked via Bitcoin headers (chaintracks), never a trusted block explorer.
A node only needs to reach the coordinator over HTTP — run it on a cloud VM, a home server, or a Raspberry Pi. Open enrollment, curated approval (the Forta model). The network is early and growing — every independent node, in a different place on a different network, makes the proof harder to dispute. That's why we want you on it.
