About this artifact

The protocol's first on-chain footprint is this proof-of-burn (block 278319, 2014-01-02). The first decodable CNTRPRTY-marked protocol message followed ten days later — see counterparty-first-message (block 280091, 2014-01-12).

How it was stored

Bare multisig outputs list several public keys and say how many signatures are needed to spend them. Uploaders discovered that the public-key slots could carry arbitrary bytes. A transaction can include many such multisig outputs, each carrying one or more fake key-sized chunks.
