How it works

• From Decrypt (7-3-2023):

"According to Rollkit, its new rollup solution lets users produce rollups by retrieving and storing data on the Bitcoin blockchain. It was inspired by Ordinals, the Bitcoin NFT protocol which showed developers that—using Taproot—users could post arbitrary data to the blockchain. In the traditional sense, rollups are batches of transactions that are “rolled up” off chain into one transaction, and then posted to Ethereum as a single on-chain transaction. This helps free up blockspace and lower transaction costs on the network, while still inheriting the settlement assurances of the base chain.

A sovereign rollup is one that does not need a smart contract or use a settlement layer for validation—scalable and secure and with the "sovereignty" of a layer 1. Ryan Berckmans said on Twitter that the sovereign rollup “is actually an alt L1 that stores its block data on Bitcoin.” According to Alexei Zamyatin, founder of the Bitcoin DeFi protocol Interlay, sovereign rollups as proposed by Rollkit inherit “nothing” of Bitcoin’s security".

• From Bitcoin.com (7-3-2023):

"To make this possible, the Rollkit team used Taproot transactions to read and write data on Bitcoin and created the “bitcoin-da” package to provide the necessary interface. They also implemented the “SubmitBlock” and “RetrieveBlocks” functions for Rollkit to interact with Bitcoin."

Competition

• From Decrypt (7-3-2023):

"Some are likening sovereign rollups to Stacks, a high functionality layer 1 protocol that settles its blocks on the Bitcoin blockchain for security purposes. Stacks co-founder Muneeb Ali said on Twitter that this is an apt comparison, but noted some key differences.

On one hand, it takes 150 Stacks blocks before a transaction reaches ”Bitcoin finality” on Stacks, but only 1 with sovereign rollups. On the other, Stacks blocks publish their data to Bitcoin in an efficient manner by merely hashing the data on-chain, whereas sovereign rollups publishes the full data.

“The technically challenging part for both the Stacks layer and sovereign rollups is moving BTC in and out of the layer, said Ali. “The decentralized BTC peg is the most important part.”"
