Scaling Bitcoin: RSK

This is the second part of a Bitcoin research series, where we will be exploring the technical details and growth of scaling solutions built atop the Bitcoin blockchain. The previous parts in this series can be found here:

In this piece, we focus on Rootstock (RSK), a merged-mined chain that leverages Bitcoin’s security by using the same Proof-of-Work mining algorithm as Bitcoin. Using a merged-mined model, RSK is able to reduce the friction for existing Bitcoin miners to enter the RSK ecosystem as a miner, thereby encouraging miners to contribute towards RSK’s security (in the form of hash power) at negligible marginal cost.
