Asynchronous Federated Learning on Heterogeneous Devices: A Survey (2021, background): “Proof of Work (PoW) [30], Proof of Stake (PoS) [32], and PBFT [33] stand as the three most prevalent consensus algorithms.”
OmniLedger: A Secure, Scale-Out, Decentralized Ledger via Sharding (2018, methodology): “Other approaches for establishing Sybil-resistant identities such as Proof-of-Stake (PoS) [31], [25], Proof-of-Burn (PoB) [46] or Proof-of-Personhood [8] overcome PoW’s problems and are compatible with ByzCoins identity (key-block) blockchain, and in turn with OmniLedger”
Ouroboros Praos: An Adaptively-Secure, Semi-synchronous Proof-of-Stake Blockchain (2018, methodology): “Our protocol is based on a previous proof-of-stake protocol, Ouroboros [16], as its analysis builds on some of the core combinatorial arguments that were developed to analyze that scheme.”
Blockchain without Waste: Proof-of-Stake (2020, neutral): “More recent papers within that literature, with relevance to permissionless blockchains, include Miller and LaViola (2014), Chen and Micali (2016), Pass and Shi (2016) and Kiayias, Russell, David, and Oliynykov (2017).”
A Vademecum on Blockchain Technologies: When, Which, and How (2019, background): “Hence the need of unbiased unpredictable random elections as those adopted in [275], [276].”
A Survey on Consensus Mechanisms and Mining Strategy Management in Blockchain Networks (2018, methodology): “In order to maximize the proﬁts, a block leader could generate conﬂicting blocks on all possible forks with “nothing at stake”, since generating a PoS block consumes no more resource than generating a signature.”
Tesseract: Real-Time Cryptocurrency Exchange using Trusted Hardware (2017, background): “In particular, in a proof-of-stake [16, 33, 12, 45, 37, 27, 40] based cryptocurrency the scarce resources are the coins that circulate in the system, and in a proof-of-space [66] based cryptocurrency the scarce resource is storage space.”
Verifiable Delay Functions (2018, background): “All known proof-of-stake systems are vulnerable to long-range forks due to post-hoc stakeholder misbehavior [46, 55, 45, 13].”
A Survey of IoT Applications in Blockchain Systems (2020, background): “Proof-of-Stake (PoS) [Kiayias et al. 2017] relies on a hypothesis that users holding more currency are more incentived to ensure the reliability of the system, and is less likely to play as malicious nodes.”
Solutions to Scalability of Blockchain: A Survey (2020, methodology): “[19] B. David, P. Gaži, A. Kiayias, and A. Russell, ‘‘Ouroboros praos: An adaptively-secure, semi-synchronous proof-of-stake blockchain,’’ in Proc.”
A Survey of Distributed Consensus Protocols for Blockchain Networks (2019, methodology): “Because of its reduced synchrony requirement and the privacy-preserving nature of the VRF scheme, Ouroboros Praos does not limit the size of consensus participants and allows for a flexible committee.”
Biscotti: A Blockchain System for Private and Secure Federated Learning (2021, background): “PoF is a consensus protocol for secure and private federated learning based on a recently proposed blockchain consensus mechanism called proof-of-stake (PoS) [32], [56].”
FruitChains: A Fair Blockchain (2017, background): “Notably, recent provably secure proofof-stake protocols, including Snow White [5] and Ouroboros [13], argue that the idea from FruitChain is applicable to non-proof-ofwork blockchains as well.”
Monoxide: Scale out Blockchains with Asynchronous Consensus Zones (2019, methodology): “Existing PoS systems adopt different methods to produce the randomness in the leader election to ensure decentralization and security [22, 7, 45, 18].”
