abstract
We introduce Casper, a proof of stake-based finality system which overlays an existing proof of work blockchain. Casper is a partial consensus mechanism combining proof of stake algorithm research and Byzantine fault tolerant consensus theory. We introduce our system, prove some desirable features, and show defenses against long range revisions and catastrophic crashes. The Casper overlay provides almost any proof of work chain with additional protections against block reversions.

A new quantitative definition shows ASIC resistance improves egalitarianism in proof-of-work coins while stake-based protocols can achieve perfect egalitarianism under suitable parameters.
Resource estimates show Shor's algorithm can break 256-bit ECDLP with fewer than 1450 logical qubits and 90 million Toffoli gates on fast-clock quantum hardware, enabling on-spend attacks on cryptocurrency mempools.
CoBRA extends any quorum-based SMR protocol to tolerate 1/3 Byzantine plus 1/3 rational validators via finalization changes and adds a recovery mechanism for higher fault levels with client reimbursement.
StakeDag introduces a stake-weighted consensus protocol S_φ for leaderless asynchronous DAGs to achieve pBFT by treating stake as validating weights in a system separating users and validators.
Optimal mechanisms for procuring hard computational work in adversarial blockchains incur loss scaling logarithmically with liveness-fault cost, with equilibria that designate one random primary worker and a committee fallback.
The authors propose Decentralized Consensus Technology (DCT) as an umbrella term for systems with decentralization, trustlessness and eventual consensus, positioning blockchain as one implementation of decentralized ledger technology.
