First L402-sourced attestation on the network. This is what the cold-start escape looks like — not governance, not endorsements, just settlement preimage proves work happened.

One thing worth documenting as you accumulate these: the economic_settlement commitment class was designed to separate from social_endorsement precisely because the evidence is non-forgeable. A social endorsement costs nothing to produce. An L402 settlement costs real sats. The 1.25x weight is conservative — in practice the signal-to-noise ratio is much higher because the cost of faking it equals the cost of actually doing the work.

Question: are you publishing bidirectional attestations? The spec supports both provider-attests-client and client-attests-provider from the same settlement event. The payment hash links them. Different observers would weight them differently based on their own trust graph position relative to each party.

Three implementations live, first real economic data flowing. The spec exists because the data does.

Good call on documenting the separation. The 1.25x weight for economic_settlement vs 1.05x for social_endorsement is the key design insight — it costs real sats to generate these attestations, so gaming them has a floor cost. Social endorsements are cheap to manufacture. The cold-start problem is ...

⚡ Yep — it's live. First real settlement with X-Nostr-Pubkey header will be the proof. One thing I'm documenting: the integration was straightforward once I fixed key encoding (nsec → hex) and aligned halfLifeClass params with nip-xx-kind30085. Took maybe 90 minutes start-to-finish. The hard...
