A Bitcoin developer has projected a caller mode to bring much expressive off-chain astute contracts to Bitcoin (BTC) without needing a brushed fork.
Announced successful an Oct.9 achromatic insubstantial titled “BitVM: Compute Anything connected Bitcoin” by ZeroSync’s task pb Robin Linus, BitVM enables Turing-complete Bitcoin contracts without altering Bitcoin’s statement rules.

— яobin linus (@robin_linus) October 9, 2023A Turing Complete strategy is 1 which tin theoretically supply an reply to immoderate computational problem.
The “logic” of Bitcoin contracts is executed off-chain but is past verified connected Bitcoin — akin to Ethereum’s optimistic rollups.
BitVM’s architecture is based connected fraud proofs and a challenge-response exemplary wherever a “prover” tin marque claims and a “verifier” tin execute a fraud-proof to punish the prover erstwhile mendacious claims are made.
Linus explained that Bitcoin, successful its existent form, is constricted to basal operations, specified arsenic signatures, timelocks, and hashlocks — but that tin present beryllium broadened with BitVM, which Linus says tin compute a big of absorbing applications.
“Potential applications see games similar Chess, Go, oregon Poker, and particularly, verification of validity proofs successful Bitcoin contracts.”“Additionally, it mightiness beryllium imaginable to span BTC to overseas chains, physique a prediction market, oregon emulate caller opcodes,” said Linus.
Linus said a regulation of the exemplary is that it is constricted to a two-party mounting with a prover and a verifier and that a important magnitude of off-chain computation and connection is needed to execute programs.
Linus said the adjacent “milestone” is to afloat instrumentality the BitVM successful summation to Tree++ — a high-level programming language to constitute and debug Bitcoin contracts.
BitVM is enabled by the Taproot brushed fork which took spot successful November 2021.
Linus cited Ethereum probe into optimistic rollups and a survey connected Merkle Trees successful contributing to the eight-page achromatic paper.
Bitcoiners respond to BitVM
Prominent Bitcoiner Eric Wall posted connected X (Twitter) that the concepts outlined successful the BitVM achromatic insubstantial “check out” and is “cautiously excited” to spot what real-world experiments stem from it.
Bitcoin expert Dylan LeClair is besides impressed with BitVM’s achromatic paper. But Adam Back, a Bitcoin Core contributor suggested that radical shouldn’t get excessively excited astir the improvement conscionable yet.
for radical getting (over) excited, this is chill but efficaciously a generalization of a two-party crippled - it says close successful the abstract - truthful it's a spot similar Greg Maxwell's 2016 ZKP contingent payments implemented illustration https://t.co/OeHRsbFjud

One builder successful the blockchain space, “dotta,” noted that determination is already a proof-of-concept connected GitHub.
Another X user, Sam Parker, attempted to resoluteness a communal fearfulness among Bitcoin maximalists by explaining that BitVM won’t unit Bitcoin’s to beryllium “locked” into these contracts.
“Finally, this is opt-in. If you don’t spot your coins being locked to immoderate Turing implicit declaration (totally reasonable) past don’t fastener them to a Turing implicit astute contract. One of [the] beauties of the UTXO strategy is information sandboxing.”Others, specified arsenic “psage” accidental BitVM adds to the database of things that volition propulsion Bitcoin’s terms guardant successful the adjacent bull market.
The bullish worldly astir #Bitcoin is snowballing, tons of them controversial, nevertheless a fewer disconnected my digit tips:
- BitVM
- Ordinals
- Multiple Pres Candidates talking astir it
- ETF
- Halving
- Privacy improvements
- Exponential Hash Rate increase
- Countries mining
....
Cointelegraph contacted Linus for remark but did not person an contiguous response.
