Max Mathys, Roland Schmid, Jakub Sliwinski +1
We present Accept, a simple, asynchronous transaction system that achieves perfect horizontal scaling. Usual blockchain-based transaction systems come with a fundamental throughput…
ABC: Proof-of-Stake without Consensus
Jakub Sliwinski, Roger Wattenhofer
We introduce a new permissionless blockchain architecture called ABC. ABC is completely asynchronous, and does rely on neither randomness nor proof-of-work. ABC can be parallelized…
