Game-Theoretic Randomness for Proof-of-Stake
, 2023 Many protocols in distributed computing rely on a source of randomness, usually called a random beacon, both for their applicability and security. This is especially true for proof-of-stake blockchain protocols in which the next miner or set of miners have to be chosen randomly and each party’s likelihood to be selected is in proportion to their stake ...

Analyzing the Fairness of Proof of Stake Ethereum.
The paper presents an analysis of fairness within the Proof of Stake (PoS) Ethereum protocol Gasper, utilizing simulations conducted with the PRISM+ modelling tool. Our study focuses on stake analyses, revealing that stake growth dynamics are tangled to the initial distribution of the stake.

Proceedings of the 3rd Workshop on Cryptocurrencies and Blockchains for Distributed Systems, 2020
There have been several 51% attacks on Proof-of-Work (PoW) blockchains recently, including Verge and GameCredits, but the most noteworthy has been the attack that saw hackers make off with up to $18 million after a successful double-spend was executed on the Bitcoin Gold network.

Distributed Ledger Technologies: Research and Practice, 2022
In the last few years, a number of blockchain-based online platforms decided to use consensus procedures other than Proof of Work (PoW), originally adopted by Bitcoin. An alternative protocol, which attracted much attention, is the so-called Proof-of-Stake (PoS), which unlike PoW consensus is not based on solving an energy-consuming ...

Equilibrium Staking Levels in a Proof-of-Stake Blockchain
SSRN Electronic Journal, 2021We study the equilibrium level of staking in a Proof-of-Stake blockchain when investors have different trading horizons. We find that, contrary to conventional wisdom, staking levels do not always increase in block rewards. Rather, block rewards serve as an inflationary transfer from short-horizon cryptocurrency investors to long-horizon cryptocurrency

Anonymous Lottery In The Proof-of-Stake Setting
2020 IEEE 33rd Computer Security Foundations Symposium (CSF), 2020When Proof-of-Stake (PoS) underlies a consensus protocol, parties who are eligible to participate in the protocol are selected via a public selection function that depends on the stake they own. Identity and stake of the selected parties must then be disclosed in order to allow verification of their eligibility, and this can raise privacy concerns.

Stake-Bleeding Attacks on Proof-of-Stake Blockchains
2018 Crypto Valley Conference on Blockchain Technology (CVCBT), 2018We describe a general attack on proof-of-stake (PoS) blockchains without checkpointing. Our attack leverages transaction fees, the ability to treat transactions "out of context," and the standard longest chain rule to completely dominate a blockchain. The attack grows in power with the number of honest transactions and the stake held by the adversary ...

Tokenomics and Perspectives of Proof of Stake [PDF]
CEUR Workshop Proceedings, Vol-3665: Proceedings of the Digital Economy Concepts and TechnologiesEver since the first block of the Bitcoin network was created, the relevance of research into the assessment of the prospects of the blockchain project is constantly increasing. Ultimately, the economics of a token will have a big impact on how it will be used, how easy it will be to build a network, and whether there will be much interest in the ...

On PeerCoin Proof of Stake for Blockchain Consensus
2021 The 3rd International Conference on Blockchain Technology, 2021Proof of Stake (PoS) has been talked about extensively as an alternative way of reaching consensus in blockchain systems. However, there are few publications on how PoS can be used to create new blocks in detail. The undisputed lead proponent for PoS is Ethereum.
