Proofless Consensus & Client-side Validation

on YouTube ↗31m

" summary

Claim: validation moves entirely to clients while consensus only detects double spends by checking ephemeral pubkeys, reducing on-chain data to a tachygram tuple (old pubkey, new commitment) inscribed via a BitVM3 bridge using Argo garbling. Implementation uses recursive zero-knowledge proofs / proof-carrying data so each client verifies inclusion or non‑inclusion in constant time with constant-size proofs, suitable for light devices; prototype architecture exists but Sybil resistance and practical UX/backups remain open.
