Witness
Signed observations of who holds what, checked against the chain. One address, one block, two readers, every disagreement settled by the chain itself, signed by whoever looked. 6 entries, 3 people, Ethereum and Tezos.
What an entry is
A published work is a chain of references, and the chain starts with who holds the token. Every reader of a blockchain, ours included, can be wrong about that: an index lags, drops a token standard, or keeps listing a token after it moved. A witness entry records, for one address at one block, what each public reader returned, where the readers differ, and what the chain itself says about a random sample from each list and about every token the readers disagree on. The chain decides. A reader is right or wrong per token, never in general.
Each entry is a JSON file signed by whoever ran the check, in the same signature envelope the DP-1 playlist format uses. The signature covers the content, so an entry stays valid wherever it is served. Anyone can produce one, from their own readers, their own node, and their own key.

How a check runs
Ask each reader for the address’s holdings. Pin a block. Compare the two lists per token standard. Then ask the chain, at that block, about a seeded random sample from each list and about every token only one reader lists. On Ethereum the question is ownerOf(tokenId) for ERC-721 and balanceOf(address, tokenId) for ERC-1155, by eth_call; on Tezos it is the contract’s own %ledger big map, read from a node by key hash. A token the reader lists that the chain says is held elsewhere, or that no longer exists, is a reader error or lag. A token the chain says is held that a reader omits is an under-count. A contract that cannot be asked this way is recorded as unanswerable and counts for neither side. Every not-held verdict is re-read on a second node.
Readers today: Ethereum, the Feral File indexer and Blockscout; Tezos, TzKT and objkt. The readers are the ones we and the apps around us depend on. None of them is treated as the truth.
Verify an entry
No install beyond Node. The script recomputes the canonical bytes, checks the payload hash, and checks the Ed25519 signature against the public key in the signer’s did:key.

Every entry here so far was written by Feral File. The point of the shape is that the next one need not be.
