As the Rollup narrative dominates Ethereum, the Bitcoin Layer2 ecosystem is undergoing significant structural development.
In September 2025, BitcoinZK announced that its native governance token, ZYRA, would be officially listed on Gate. This is not merely a listing event—it is the project’s first constitutional invitation to the market under its vision of a “Bitcoin Constitutional System.”
At this moment, BitcoinZK is seeking to broaden the definition of Bitcoin Layer2 from a scaling solution to a governance-enabled framework that integrates Bitcoin nativity, ZK verification, and institutional governance tools
ZK Rollup × Sovereign Design: ZK as the Only Viable Path for Bitcoin Layer2
As BitcoinZK CMO Brian Lau noted, Bitcoin’s scripting system cannot natively support smart contract–based Rollup verification. This means all L2 scaling designs inevitably introduce trust assumptions.
BitcoinZK’s core design proposes “100% ZK proof generation × 100% public verification”:
- All user actions and L1–L2 cross-chain activities are validated by ZK-SNARKs to guarantee their correctness
- The verification process is fully open and can be audited by any third party
With foundational support from zkBridge and Threshold Network, BitcoinZK brings BTC assets into the EVM environment, enabling a fusion of BTC Gas and EVM smart contracts, laying the groundwork for programmable Bitcoin in DeFi and asset issuance.
ZYRA: Not a Gas Token, but a “Digital Constitution”
Unlike many “utility tokens,” ZYRA is not designed for payments—it exists for governance.
According to the official governance model:
- ZYRA grants holders the rights
