Developed by the ZK network launched by RISC Zero, the system is intended to settle computation-heavy proofs on Bitcoin while leaving execution on smart contract platforms such as Ethereum and Base.<\/p>\n<p>Under the initial rollout, ZK proofs produced on Ethereum mainnet and Base Layer 2 are verified and finalised using Bitcoin, effectively linking programmable execution environments to Bitcoin\u2019s security model. Boundless CEO Shiv Shankar stated that the design is not intended to replicate Ethereum on Bitcoin, saying, \u201cBitcoin serves as the final verifier and settlement layer for ZK proofs\u201d.<\/p>\n<p><strong>Related: \u2018Bitcoin Lottery\u2019 Buzz Fizzles After Untagged Blocks Traced to NiceHash Test<\/strong><\/p>\n<h2 class=\"wp-block-heading\" id=\"h-anchoring-zk-proofs-to-bitcoin\">Anchoring ZK Proofs to Bitcoin<\/h2>\n<p>The system relies on Bitcoin Virtual Machine, or BitVM, an off-chain verification framework that enables validation of complex computation without modifying Bitcoin\u2019s protocol. First proposed in 2023 and launched in mid-2025, BitVM allows computation outcomes to be anchored to Bitcoin through its scripting model rather than native execution.\u00a0<\/p>\n<p>\u201cWhat BitVM unlocks\u2026 is the ability to anchor real computation to Bitcoin without changing Bitcoin in any way\u201d.<\/p>\n<p>Boundless has also integrated Citrea, a Bitcoin-native ZK rollup that is part of a broader effort to extend Bitcoin\u2019s functionality as a verification layer. According to Shankar, the Bitcoin ecosystem is shifting beyond a pure store-of-value role toward increased verification without consensus changes, driven in part by growing demand from rollups for stronger and more neutral settlement layers. Boundless intends to expand integrations beyond Ethereum and Base, laying groundwork for Bitcoin to act as a shared settlement layer across multiple blockchain networks.<\/p>\n<p><strong>Related: Crypto Investment Products See Largest Weekly Inflows Since October 2025<\/strong><\/p>\n<\/p><\/div>\n<p>Bitcoin,Boundless#ZeroKnowledge #Proofs #Turning #Bitcoin #Settlement #Layer1768984476<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Boundless has introduced a cross-chain system that settles zero-knowledge proofs from Ethereum and Base on Bitcoin without changing Bitcoin\u2019s protocol.
