Introducing Anemos: A Fair-Launch Layer-1 with a Native Stablecoin

Fri, 05 Jun 2026 00:00:00 +0000

Anemos (ἄνεμος, Greek for wind; ticker ANM) is a layer-1 blockchain that pairs a deliberately minimal, no-VM proof-of-stake core with two features that cannot be added on top of an existing chain: a fair launch and a native, protocol-level stablecoin. This post explains the thesis.

Why fork, not build on top

Anemos is a respectful fork of Pactus — a lightweight, BFT-final, sortition-PoS chain with six fixed transaction types and no virtual machine. That minimalism is a security feature, and we preserve it. But two goals are reachable only at the base layer:

The Anemos Stablecoin: A Native, Overcollateralized, Self-Stabilizing Design

Thu, 04 Jun 2026 00:00:00 +0000

The Anemos stablecoin is built as native consensus logic, mirroring the existing transfer/bond/withdraw modules. Because every node re-executes and commits a shared state root, every operation is integer/fixed-point only with defined rounding — any nondeterminism would be a chain halt.

Mint and redeem against a floor

Minting deposits ANM at the oracle price and issues stablecoin only if the post-mint collateral ratio stays above a floor (launch value ~400%). This minting-halt-below-floor rule is the anti-death-spiral mechanism — we lift Djed’s formally verified bounds rather than invent new ones. Redeeming burns stablecoin and returns ANM at the oracle price, reserve-ratio aware. Both execute against the previously committed (lagged) price, so a single block cannot be used to front-run the peg.

A Consensus-Embedded Price Oracle: Slash Deviation, Never Absence

Wed, 03 Jun 2026 00:00:00 +0000

A USD-pegged stablecoin needs a USD price, and a new chain has no native source. The oracle is the true blocker, so we designed it first. The key constraint: the price must be a pure function of on-chain data, so a node that was offline and re-syncs derives the identical value.

Price rides in the block, not in a transaction

We do not touch the consensus vote or certificate hot path — the riskiest code in the chain. Instead, each block a deterministic ~committee subset (ranked by Hash(seed‖valNum) over the committed H−1 sortition seed, so every node re-derives it with zero storage) signs the canonical message H(height‖valNum‖price) with its validator BLS key and gossips a PriceVote. The proposer aggregates the subset’s votes into one BLS aggregate in a block-body OracleData section, whose hash is folded into Block.Hash(). The existing precommit certificate therefore attests the oracle data with zero certificate-format change.

Fair-Launch Tokenomics: Minted Emission Without a Premine

Most chains pay their block subsidy out of a finite premined treasury — which both concentrates genesis supply and eventually runs dry. Anemos does neither.

No premine, no treasury balance

The inherited design premined coins to insider accounts plus a large treasury and paid the subsidy from it. Anemos replaces this with a fair launch: the Treasury address is a zero-balance sentinel that exists only as a minting source. The block subsidy is minted — credited to recipients with no sender debit — so there is no premine to draw down and no insider allocation.
