OHIE: Blockchain Scaling Made Simple

Understand

Many blockchain consensus protocols have been proposed recently to scale the throughput of a blockchain with available bandwidth.

• However, these protocols are becoming increasingly complex, making it more and more difficult to produce proofs of their security guarantees.
• We propose a novel permissionless blockchain protocol OHIE which explicitly aims for simplicity.
• OHIE composes as many parallel instances of Bitcoin's original (and simple) backbone protocol as needed to achieve excellent throughput.
