Ethereum – RSK Is Altering How It ‘Pegs’ Bitcoin to Its Sidechain
Bitcoin sidechain developer RSK is revamping how customers swap bitcoin for its community’s tokenized model of the cryptocurrency.
IOVlabs, the corporate that develops the RSK platform, has created a brand new system for monitoring how bitcoin is “pegged to” (or, swapped for) RBTC, a token that represents a 1-1 peg to actual bitcoin. RBTC is the native coin on the RSK sidechain – a Bitcoin scaling resolution that makes use of a blockchain-like community that sacrifices decentralization in favor of quicker transaction speeds.
Earlier than this transformation, RSK customers would ship bitcoin to a multi-signature pockets handle – a pockets managed by 12 totally different events. The “signatories” for this pockets would then approve the transaction and switch the proportional RBTC to the consumer’s RSK pockets.

The brand new system, dubbed Powpeg, will supplant these with an automatic course of, and a lot of the 12 signatories will now act as “pegnatories,” a gaggle of validators who will monitor the RSK multi-signature pockets and the minting of RBTC to guard towards wrongdoing.
In contrast to the earlier design, Powpeg automates the ultimate step of the RBTC minting course of. Now when customers ship bitcoin to the multi-sig pockets, they generate a proof of that transaction after which ship this proof to “special-purpose hardware security modules called PowHSMs,” in line with an IOVlabs press launch. As soon as these modules obtain the proof, they distribute the RBTC to the corresponding consumer.
Within the occasion the consumer doesn’t reveal the proof, the pegnatories will present the proof, however they don’t manually log out on the transaction; that’s the PowHSM’s job, which additionally shops the person personal keys for every signatory.
Decentralizing how sidechains work
RSK co-founder and IOVlabs Chief Innovation Officer Sergio Lerner instructed Fintech Zoom that miners, exchanges and mining swimming pools will make up the primary spherical of pegnatories. He additionally expects that the variety of pegnatories “probably will grow in size in the months to come” for the reason that “security risks associated with adding pegnatories are much lower than [signatories] in a federation.”

IOVlabs says the design change was made to decentralize the pegging course of for RSK and decrease the belief concerned between the pegnatories and the customers.
The Powpeg redesign comes on the heels of IOVlab’s efforts to convey the utility of Ethereum’s DeFi apps to Bitcoin’s ecosystem. The RSK sidechain options numerous DeFi-like companies, together with the MakerDAO-like stablecoin platform Cash on Chain and Sovryn, a Bitcoin lending and derivatives market.
Launched in 2018, RSK is a Bitcoin sidechain which may help Ethereum good contracts. The RSK sidechain is “merge mined” with Bitcoin, that means miners who mine Bitcoin’s blockchain additionally contribute hash charge to mine blocks on RSK. In accordance with IOVlabs, mining swimming pools representing 50% of Bitcoin’s hashpower at the moment mine on the RSK chain.
