A Bitcoin developer has proposed a brand new solution to convey extra expressive off-chain good contracts to Bitcoin (BTC) without having a mushy fork.

Introduced in an Oct.9 white paper titled “BitVM: Compute Something on Bitcoin” by ZeroSync’s challenge lead Robin Linus, BitVM allows Turing-complete Bitcoin contracts with out altering Bitcoin’s consensus guidelines.

A Turing Full system is one which might theoretically present a solution to any computational drawback.

With BitVM, the “logic” of Bitcoin contracts could be executed off-chain however verification could be made on Bitcoin — much like Ethereum’s optimistic rollups.

BitVM’s structure is based on fraud proofs and a challenge-response mannequin the place a “prover” could make claims and a “verifier” can carry out a fraud-proof to punish the prover when false claims are made.

Linus defined that Bitcoin, in its present kind, is restricted to fundamental operations, equivalent to signatures, timelocks, and hashlocks — however that may now be broadened with BitVM, which Linus says can compute a number of attention-grabbing purposes.

“Potential purposes embody video games like Chess, Go, or Poker, and significantly, verification of validity proofs in Bitcoin contracts.”

“Moreover, it may be potential to bridge BTC to overseas chains, construct a prediction market, or emulate novel opcodes,” mentioned Linus.

Linus mentioned a limitation of the mannequin is that it’s restricted to a two-party setting with a prover and a verifier and {that a} important quantity of off-chain computation and communication is required to execute applications.

Linus mentioned the subsequent “milestone” is to completely implement the BitVM along with Tree++ — a high-level programming language to write down and debug Bitcoin contracts.

BitVM is enabled by the Taproot soft fork which befell in November 2021.

Linus cited Ethereum analysis into optimistic rollups and a research on Merkle Bushes in contributing to the eight-page white paper.

Bitcoiners reply to BitVM

Distinguished Bitcoiner Eric Wall posted on X (Twitter) that the ideas outlined within the BitVM white paper “take a look at” and is “cautiously excited” to see what real-world experiments stem from it.

Bitcoin analyst Dylan LeClair can also be impressed with BitVM’s white paper. However Adam Again, a Bitcoin Core contributor suggested that folks shouldn’t get too excited concerning the growth simply but.

One builder within the blockchain area, “dotta,” noted that there’s already a proof-of-concept on GitHub.

One other X person, Sam Parker, tried to resolve a standard worry amongst Bitcoin maximalists by explaining that BitVM received’t drive Bitcoin’s to be “locked” into these contracts.

“Lastly, that is opt-in. In case you don’t belief your cash being locked to some Turing full contract (completely cheap) then don’t lock them to a Turing full good contract. One in every of [the] beauties of the UTXO system is safety sandboxing.”

Others, equivalent to “psage” say BitVM provides to the checklist of issues that can push Bitcoin’s worth ahead within the subsequent bull market.

Cointelegraph contacted Linus for remark however didn’t obtain an instantaneous response.
