Burak, the developer who hacked Bitcoins Lightning Community with a 998-of-999 multi-signature Taproot transaction, has created a brand new Bitcoin layer 2. It has no proprietary token and doesn’t require any fork.
It’s dubbed ‘Brollups’ — a portmanteau of both ‘Burak’ and ‘rollup’ or ‘bro’ and ‘rollup.’
A rollup is a bundle of transactions that happen off-blockchain. They’re ‘rolled-up’ right into a consolidated file and mined on-chain. Also referred to as a ‘layer 2,’ they’re basically separate blockchains that borrow safety and worth from a base, ‘layer 1’ blockchain like Bitcoin.
Brollups don’t require a fork of Bitcoin’s consensus code. That is notable as a result of Burak has obtained donations for his work on a separate layer 2 that may require a Bitcoin fork: Ark. Particularly, Ark’s Digital Transaction Output (VTXO) tree requires an on-chain covenant to pre-determine transaction bushes.
In distinction, Brollups don’t depend on covenant operation codes like CheckTemplateVerify or TransactionHash in Bitcoin Core software program.
Burak launches new Bitcoin layer 2
Burak earned a little bit of notoriety as a Bitcoin developer on October 9, 2022. He broke LND, the preferred implementation of Bitcoin’s hottest layer 2, Lightning. The achievement wasn’t malicious, and he didn’t steal any cash from the stunt. As an alternative, he merely uncovered one other unintended consequence of Taproot, considered one of Bitcoin’s most complex and counterintuitive software program upgrades.
Through the preliminary days of promoting Taproot, many proponents marketed its skill to allow sensible contracts on Bitcoin and in any other case deprecate options of Ethereum. In actuality, lower than 2% of Bitcoin transactions utilized Taproot till Casey Rodarmor launched his NFT and token platform Ordinals.
By Might 7, 2023, roughly 4 months for the reason that launch of Ordinals, over three-quarters of Bitcoin transactions utilized Taproot.
By revealing the unintended penalties of Taproot, Burak grew to become a infamous developer. Because it seems, Taproot allowed a hacker to freeze 1000’s of bitcoins throughout the Lightning community.

In the same manner, Burak is now trying to point out how Bitcoin — with none fork or covenant OpCodes — can emulate covenants.
Certainly, many rollups and layer 2s contain belief, with preliminary variations of Ethereum’s hottest layer 2s, Arbitrum and Optimism, counting on management management of personal keys over a multi-sig sensible contract.
So, if a layer 2 reintroduces belief and centralization anyway, why is a separate token like Optimism’s OP or Arbitrum’s ARB wanted in any respect?
Coinbase launched a layer 2, Base, with none proprietary token. Base depends closely on Coinbase as a trusted celebration. Equally, Burak’s Brollups introduce belief in a small group of Brollup operators and permit low cost, quick Bitcoin transactions with out introducing any further token.
