From Permissioned to Proof-of-Stake Consensus [PDF]
IACR Cryptol. ePrint Arch.This paper presents the first generic compiler that transforms any permissioned consensus protocol into a proof-of-stake permissionless consensus protocol. For each of the following properties, if the initial permissioned protocol satisfies that property in the partially synchronous setting, the consequent proof-of-stake protocol also satisfies that ...

The Application of Proof of Stake: Advantages, Challenges and Future Development [PDF]
ITM Web of ConferencesWith the development of consensus mechanism, researchers emphasize the need to strengthen the Proof of Stake consensus process. Problem like how to keep the transaction platform protocol fair; how to decentralize the digital transaction system etc.

Practical Large-Scale Proof-Of-Stake Asynchronous Total-Order Broadcast [PDF]
, 2023 We present simple and practical protocols for generating randomness as used by asynchronous total-order broadcast. The protocols are secure in a proof-of-stake setting with dynamically changing stake.

Looking for stability in proof-of-stake based consensus mechanisms
Blockchain: Research and ApplicationsThe Proof-of-Stake (PoS) consensus algorithm has been criticized in the literature and in several cryptocurrency communities, due to the so-called compounding effect: who is richer has more coins to stake, therefore a higher probability of being selected

Proofs of Proof-of-Stake with Sublinear Complexity
CoRR, 2022 Popular Ethereum wallets (like MetaMask) entrust centralized infrastructure providers (e.g., Infura) to run the consensus client logic on their behalf. As a result, these wallets are light-weight and high-performant, but come with security risks. A malicious provider can mislead the wallet by faking payments and balances, or censoring transactions.

An Event Study of the Ethereum Transition to Proof-of-Stake
Commodities, 2023 On 15 September 2022, the Ethereum network adopted a proof-of-stake (PoS) consensus mechanism. We study the impact on the network and competing platforms in a two month event window around the Beacon chain merge.

Технічна інженерія, 2023 Existing mechanisms for the Proof-of-Stake and Proof-of-Work decision-making systems in blockchains are thoroughly studied and compared at work. Consensus methods are considered a process of agreeing on a new block that is subsequently added to the ...

Proof-of-Stake Sidechains [PDF]
2019 IEEE Symposium on Security and Privacy (SP), 2019 Sidechains have long been heralded as the key enabler of blockchain scalability and interoperability. However, no modeling of the concept or a provably secure construction has so far been attempted. We provide the first formal definition of what a sidechain system is and how assets can be moved between sidechains securely.
