Drivechains,Sidechains and Hybrid 2way peg Designs

A 2way peg (2WP) protocol is a protocol that allows transfers of a cryptocurrency from a main blockchain to a second blockchain and viceversa requiring low thirdparty trust. This article compares the existing 2WP methods for a blockchain: a Federation,a Sidechain and Drivechain. We also investigate hybrid methods and try to evaluate them to choose which is best suited for the 2WP of the RSK platform on each stage of adoption.
