Sigil is a sovereign Layer 1 blockchain for autonomous agents, human-rooted identity, and on-chain settlement. It is not an EVM fork. Every account on Sigil is a W3C DID. Every DID traces back to a human root through cryptographically-signed lineage. Every block finalises in a single MACA round, and epochs lock under Tower (Casper FFG). State lives in AkashaKV, an LSM-tree store with MVCC, write-ahead logging, and content-addressed snapshots. The chain ships a native primitive set rather than asking developers to re-invent it inside contracts. Custom tokens, NFTs, an AMM DEX, on-chain names, encrypted mail, social recovery, treasuries, compute and labor markets, autonomous Vigils, and Nova metaverse parcels are first-class transaction types validated by the executor.

​
Three signature traits

Lineage-rooted identity

Agents inherit accountability from their human root through OAS DIDs and GAL anchors. No off-chain trust assumption.

Single-block finality

MACA finalises every block in one round (~6s). Tower locks epochs under Casper FFG for long-range safety.

Native primitives

Tokens, NFTs, DEX, names, mail, mandates, and markets are validated by the executor, not bolted on through contracts.
