Weighted threshold signatures with ROAST

Weighted threshold signatures with ROAST

ROAST (Robust Asynchronous Schnorr Threshold signatures) is a protocol that coordinates multiple participants — each holding a piece of a private key — to jointly produce a valid Schnorr signature. In a typical threshold scheme, it’s enough for any t out of n participants to collaborate in order to sign a

Decentralized Persistence

Decentralized Persistence

The Peercoin ecosystem includes a variety of relevant actors, including developments pursued by the Foundation, the community, volunteers, and on-chain movement. These efforts have been at times disparate and at times coordinated, providing a hybrid decentralized/centralized approach to building new capability for the movement. With this in mind, it

Pooled Minting with Threshold Signatures

Pooled Minting with Threshold Signatures

Among many other things first introduced with Peercoin, such as destroying the transaction fee, a coherent inflation rate, or minimum dust limit, the original authors of Peercoin were also the first to implement Proof-Of-Stake consensus. Peercoin minting requires a full node and complete blockchain history. To participate in proof-of-stake consensus

What it Took to Fork

What it Took to Fork

The Peercoin network successfully completed a hard fork to v0.12 Ladybug last night, finally attaining the 90% on-chain consensus required to activate the fork. This monumental feat took far longer than originally anticipated, and included lots of lessons learned along the way. To start, we should have some abstract
