FAT

#4584

Datachain Rope is a public, EVM-compatible, post-quantum Layer 1 smartchain (chainId 271828). Its native coin is FAT, launched at native chain genesis on 2026-03-25 with a 10,000,000,000 FAT genesis supply and an asymptotic ~18,000,000,000 FAT ceiling reached over decades via a 4-year-halving anchor-knot emission schedule (Era 1 = 500,000,000 FAT/yr, floor 1,000,000 FAT/yr).

The protocol is specified by the Quipu Primitive Canon (currently v2.0), which replaces the block/chain/miner/fork lexicon with knot/string/cord/witness. This is not cosmetic: each ecosystem entity (wallet, contract, tokenized asset, decentralized identifier, or the federation itself) owns its own sovereign micro-ledger called a "string"; events on that string are individually addressable "knots" rather than slots in a globally-shared block container. Three properties follow that block-based ledgers cannot express natively: (1) per-entity sovereign history; (2) individually addressable AND individually erasable event entries via cryptographic tombstoning (rope_untieKnot), satisfying GDPR Article 17 at substrate level; (3) hybrid post-quantum signatures (Ed25519+Dilithium3 for signing, X25519+Kyber768 for key exchange) at the consensus layer.

Consensus is Testimony Consensus, in which knot witnesses (the post-quantum equivalent of the historical quipucamayoq) anchor knots to the federation cord every ~4.2 seconds. Anchor-knot rewards are distributed to knot proposer (30%), testimony pool (45%), node operators (20%), federation & community (5%). No PoW mining, no ICO/IEO/IDO for FAT, no allocation-based unlock schedule.

Ecosystem platforms live on Datachain Rope from day one: Datawallet+ (sovereign wallet + ONCHAINID identity), Tanastok (real-world asset tokenization, 1,626 entities across DCNFT ERC-721 title deeds and ERC-3643 T-REX security tokens), DCSwap (native DEX with FAT/USDC, FAT/USDT, FAT/EUROD and stable pools), NaturaProof (biodiversity), Careaway (health), and DCScan at https://dcscan.io (native block explorer + Rope Graph). Five canonical AI Testimony agents (Semantic, Oracle, Insurance, Validation, Compliance) run natively with public HTTPS endpoints for semantic search and GDPR Article 17 erasure orchestration.

Governance is documented in the 2026-08-10 working paper "Governance Without a Governance Token": attested cross-chain franchise (Ethereum DC + XDC DC + Rope FAT + WFAT), 60% algorithmically-drawn jury, per-vote cost declaration in native FAT, erasure-compatible records. Contracts (VoteEscrow, CauseTokenFactory) are Timelock-owned; no separate governance token.
