Bitcoin might have handed a revolutionary technical milestone this week—one builders say will allow them to improve the community with no need to fork its code.
Coders at BitcoinOS declare they’ve efficiently verified a zero-knowledge proof (ZKP) on the Bitcoin mainnet for the primary time in historical past. This was carried out in a collection of on-chain transactions on Tuesday, with the ultimate verification occurring at Bitcoin block 853626, Decrypt was advised.
The workforce may also current this feat in entrance of a stay viewers at Bitcoin 2024 in Nashville on Thursday to show that the grandfather blockchain can already do what was lengthy dismissed as unimaginable.
“The achievement unlocks limitless scaling and performance on Bitcoin with out requiring extra adjustments to Bitcoin’s base layer,” mentioned BitcoinOS.
We now have carried out it! For the primary time ever a ZK-proof has been verified on Bitcoin Mainnet by BitcoinOS.
The ultimate verification was confirmed in block 853626.
A historic second and a historic block.

BitcoinOS is a undertaking aiming to assemble a trustless “superlayer” of interoperable rollups on Bitcoin. Rollups are layer-2 blockchains that enable for quicker, cheaper, and extra programmable transactions which are later “rolled up” and settled on a safer layer-1 chain.
For rollups to work, ZKPs are obligatory—a cryptographic methodology for proving that off-chain info is true with out disclosing the knowledge itself. Rollups and ZKPs are already a core expertise for scaling the Ethereum community, however have been overlooked of the Bitcoin scaling dialog attributable to perceived technical constraints.
That’s pressured Bitcoin builders to pursue suboptimal scaling options, reminiscent of sidechains, which require their customers to belief centralized firms and federations to not steal their BTC. In the meantime, although the extra well-known Lightning Community requires no such belief, BitcoinOS mentioned different limitations have left it trending again in direction of centralization in follow, and missing in broader adoption.
“The Lightning Community was, sadly, a really overhyped scaling resolution,” mentioned Edan Yago, core contributor to BitcoinOS, to Decrypt. “As a expertise, as a result of it’s pre-funded, and since you should hop between a number of gamers, it’s only acceptable for a really small variety of area of interest functions.”
When the workforce launched its whitepaper in April, BitcoinOS claimed its rollup system would render sidechains and different layer-2 options “utterly out of date” by letting customers bridge their BTC backwards and forwards between rollups in a near-trustless method.
In its stay presentation, BitcoinOS mentioned it is going to present that ZKPs can be utilized to create covenants—conditional funds that can’t be executed until the precise proof is offered. That is the important thing to constructing a decentralized Bitcoin bridge, a “holy grail” scaling resolution that the majority thought would require a comfortable fork to Bitcoin’s code to make a actuality.
As the primary system enabling “permissionless” upgrades to Bitcoin, Yago says BitcoinOS solidifies Bitcoin’s function as “permaware, extra dependable and everlasting than every other chain or software program.”
In his view, this makes Bitcoin the perfect basis for constructing decentralized monetary companies and funding merchandise, essentially the most vital of which—mortgages, airports, energy stations, and the like—contain contracts that final for many years. If Bitcoin turned an unstable basis by means of frequent comfortable forks, it will grow to be unsuited for this goal.
“Each single time you might have a comfortable fork, not solely are you introducing extra danger into the system… however you’re additionally creating vital frictions throughout the group of customers,” Yago argued. “Similar to we noticed with the blocksize wars… it causes main unease and uncertainty, which is strictly what you don’t need.”
When discussing Bitcoin’s blocksize wars in Might, Ethereum co-founder Vitalik Buterin praised ZKPs as a technological resolution that might have subtle political tensions round Bitcoin’s scaling debate by creating higher layer-2 scaling options that happy all sides. He additionally referenced BitVM, the computing framework from which BitcoinOS took inspiration.
“You need reliability, you need stability, you need boring,” Yago argued. “Delicate forks aren’t boring, and due to this fact they need to be rejected.”
