SoK: Consensus in the Age of Blockchains
The blockchain initially gained traction in 2008 as the technology underlying Bitcoin [105], but now has been employed in a diverse range of applications and created a global market worth over $150B as of 2017. What distinguishes blockchains from traditional distributed databases is the ability to operate in a decentralized setting without relying on a trusted third party. As such their core te...

متن کاملEstimation of Miner Hash Rates and Consensus on Blockchains (draft)
We make several contributions that quantify the real-time hash rate and therefore the consensus of a blockchain. We show that by using only the hash value of blocks, we can estimate and measure the hash rate of all miners or individual miners, with quantifiable accuracy. We apply our techniques to the Ethereum and Bitcoin blockchains; our solution applies to any proof-of-work-based blockchain t...
متن کاملSCP: A Computationally-Scalable Byzantine Consensus Protocol For Blockchains
In this paper, we design a new blockchain Byzantine consensus protocol SCP where the throughput scales nearly linearly with the computation: the more computing power available, the more blocks selected per unit time. SCP is also efficient that the number of messages it requires is nearly linear in the network size. The computational scalability property offers the flexibility to tune bandwidth ...
متن کامل(Leader/Randomization/Signature)-free Byzantine Consensus for Consortium Blockchains
This paper presents a new resilience optimal Byzantine consensus algorithm targeting consortium blockchains. To this end, it first revisits the consensus validity property by requiring that the decided value satisfies a predefined predicate, which does not systematically exclude a value proposed only by Byzantine processes, thereby generalizing the validity properties found in the literature. T...
