Bitcoin developer Burak has introduced Brollups, a powerful Layer 2 technology designed to enhance transaction efficiency on the Bitcoin network. Brollups package transactions off-chain, especially reducing costs and processing time without the need for forks or proprietary tokens.
Significance of Brollups
Brollup is a Bitcoin-native rollup solution that uses the native Bitcoin peg and does not modify the Bitcoin protocol. Also, it is done on peg on-chain and may be redeemed at any moment. Furthermore, these are in a separate category from Optimism, ZKP, and Sovereignty.
Rollups, like Sovereign Rollups, employ the Bitcoin block space as the data availability layer. However, unlike sovereign rollups, brollups are built into Bitcoin and function as a locally payable structure.
Brollups Also a Concept of VTXOs
Brollups expand on the concept of virtual UTXOs (VTXOs) and use them as a peg. However, VTXOs are not shifted to a different portion of the chain known as the Brollup. Brollups simply allow virtual UTXOs to be utilized in smart contracts for payment construction.
Brollups are coinswaps between VTXOs (virtual transaction output) and validate, allowing them to execute payment contract terms in smart contracts. VTXOs are verifiable both off-chain and on-chain, whereas calldata is validated on the client side. Brollups use calldata and VTXOs to provide tokens to the msg.sender in return for paid Bitcoin.
What Are Blockchain Rollups? Optimistic and ZK Rollups Explained in DetailBurak Hacked Lightning Network
Burak successfully manipulated the Lightning Network in October 2022 using a multi-signature Taproot transaction. It sent an emergency update to Lightning Network node operators after Burak’s actions forced all nodes to go briefly out of sync.
Burak also stated that,
“ I just did a 998-of-999 tapscript multisig, and it only cost $4.90 in transaction fees.”
During Taproot’s early promotion, several proponents touted its capacity to allow smart contracts on Bitcoin while deprecating Ethereum’s capabilities. Before Casey Rodarmor released his NFT and token platform Ordinals, Taproot was used in fewer than 2% of Bitcoin transactions.
