Babylon

On 2024-08-16 Babylon Labs announced a three-phase rollout. Phase 1 opened on 2024-08-22 and accepted Bitcoin transactions that locked BTC in self-custodial scripts. Stakers selected a Finality Provider, but the announcement was explicit that only voting power moved; the bitcoins did not.

Phase 1 was preparation rather than live proof-of-stake security. Its rules omitted consent to slashing, so the locked bitcoin could not yet be penalized. This boundary matters because later descriptions of slashable BTC security should not be projected backward onto the first cap.

Babylon Genesis launched on 2025-04-10 as bbn-1. BABY became its six-decimal native asset for gas, CometBFT validator delegation and governance. On 2025-04-11 the first 1,000 BTC from Phase 1 could register for the pilot, and permissionless registration opened on 2025-04-24.

The resulting chain has two signer sets. CometBFT validators produce blocks with BABY-backed voting power. Finality Providers add signatures backed by delegated BTC. Bitcoin checkpoints also anchor Genesis history and support a shorter BABY unbonding path.

BABY holders who delegate can earn inflationary rewards and vote directly; otherwise validators vote with delegated power. Current governance parameters publish proposal deposits, quorum, approval and veto thresholds, so voting is a protocol process rather than a claim on a company.

BTC stakers choose Finality Providers and may earn BABY, but the tokenomics page says they do not participate in governance. Registration binds Bitcoin and Babylon addresses. Before a delegation becomes active, six of the nine current covenant keys must sign its predefined early-unbonding and slashing transactions; current bbn-1 parameters set BTC slashing at 0.1%. Once those signatures are present, an EOTS double-sign exposes the Finality Provider’s private key and can complete the slash path. The committee cannot spend outside the script or prevent the timelock-expiry path, while its keys and quorum remain governance parameters.

Neither role creates a documented redemption claim or equity stake in Babylon Labs or the Babylon Foundation. BABY’s evidenced rights are chain use, staking rewards under mutable parameters and governance voting.

The bbn-1 genesis file contains 10 quadrillion ubbn, equal to 10 billion BABY. The allocation placed 30.5% with early investors, 15% with the team and 3.5% with advisers. Community Incentives received 15%, fully unlocked under Foundation management. Ecosystem Building and R&D and Operations each received 18%; each had 25% unlocked at launch and the remainder unlocking linearly from the first anniversary. The Foundation may reallocate unlocked R&D and Operations tokens to community incentives or ecosystem building.

Current tokenomics sets annual inflation at 5.5%, reduced from 8%. It also publishes an amended 36-month investor, team and adviser release schedule from 2026-05-10 through April 2029. The schedule is not a live circulating-supply ledger, and governance can change economic parameters.

Current protocol documentation adds a co-staking pool for users active on both sides. Its score takes the smaller of active BTC and BABY converted by a governance-adjustable ratio. This rewards balanced participation, while BTC rewards, BABY validator rewards and operator compensation remain separately withdrawable categories.

By the end of 2025 Babylon Labs was emphasizing staking infrastructure and trustless vault research. Those later products can create demand for BABY, but planned fees or future vault utility are not current holder rights until code, governance and deployment evidence make them so.
