Burak, the developer who hacked Bitcoins Lightning Network with a 998-of-999 multi-signature Taproot transaction, has created a recent Bitcoin layer 2. It has no proprietary token and does no longer require any fork.
It’s dubbed ‘Brollups’ — a portmanteau of either ‘Burak’ and ‘rollup’ or ‘bro’ and ‘rollup.’
A rollup is a bundle of transactions that occur off-blockchain. They’re ‘rolled-up’ proper into a consolidated file and mined on-chain. Frequently identified as a ‘layer 2,’ they’re in actual fact separate blockchains that borrow safety and price from a poor, ‘layer 1’ blockchain like Bitcoin.
Brollups don’t require a fork of Bitcoin’s consensus code. This is principal as a result of Burak has obtained donations for his work on a separate layer 2 that may per chance per chance per chance per chance require a Bitcoin fork: Ark. In particular, Ark’s Digital Transaction Output (VTXO) tree requires an on-chain covenant to pre-settle transaction timber.
In disagreement, Brollups don’t count on covenant operation codes like CheckTemplateVerify or TransactionHash in Bitcoin Core tool.
Burak launches recent Bitcoin layer 2
Burak earned rather of notoriety as a Bitcoin developer on October 9, 2022. He broke LND, potentially the most authorized implementation of Bitcoin’s most authorized layer 2, Lightning. The achievement wasn’t malicious, and he didn’t take any money from the stunt. Instead, he merely uncovered one other unintended of Taproot, one among Bitcoin’s most advanced and counterintuitive tool upgrades.
Within the midst of the initial days of promoting Taproot, many proponents marketed its ability to enable tidy contracts on Bitcoin and in some other case deprecate aspects of Ethereum. In actuality, no longer as much as 2% of Bitcoin transactions utilized Taproot unless Casey Rodarmor launched his NFT and token platform Ordinals.
By Could in all probability well additionally 7, 2023, roughly four months for the reason that beginning of Ordinals, over three-quarters of Bitcoin transactions utilized Taproot.
By revealing the unintended penalties of Taproot, Burak turned a notorious developer. Because it appears, Taproot allowed a hacker to freeze thousands of bitcoins all around the Lightning community.

In a similar capability, Burak is now making an try to show how Bitcoin — with none fork or covenant OpCodes — can emulate covenants.
Indeed, many rollups and layer 2s uncover trust, with initial variations of Ethereum’s most authorized layer 2s, Arbitrum and Optimism, relying on leadership control of non-public keys over a multi-sig tidy contract.
So, if a layer 2 reintroduces trust and centralization anyway, why is a separate token like Optimism’s OP or Arbitrum’s ARB wished at all?
Coinbase launched a layer 2, Putrid, with none proprietary token. Putrid depends heavily on Coinbase as a relied now and again. Equally, Burak’s Brollups introduce trust in a diminutive neighborhood of Brollup operators and enable cheap, rapid Bitcoin transactions without introducing any further token.
