Powpeg is a proof-of-work secured two-way peg
used to interact between the RSK side chain and the
Bitcoin blockchain. Powpeg is the first Bitcoin peg to
provide security assurances based on Bitcoin's
proof-of-work, making it the most secure and
permissionless peg available today.
In the Powpeg, no single entity, or group, has the power to unilaterally
perform peg-out operations, not it can control the peg or selectively censor
peg-outs. There are already eleven high-profile companies
participating on RSK to provide support to Powpeg.
The RSK community is developing additional
technologies to further improve and decentralize
the peg, including the addition of HSM attestation,
reduced peg-in and peg-out times, cross-blockchain
contract calls, and safety systems such as a
time-locked emergency federation.
