A Framework for Blockchain Interoperability and Runtime Selection [PDF]
arXiv, 2019 The suitability of a particular blockchain for a given use case depends mainly on the blockchain's functional and non-functional properties. Such properties may vary over time, and thus, a selected blockchain may become unsuitable for a given use case. This uncertainty may hinder the widespread adoption of blockchain technologies in general.

2016 IEEE 15th International Symposium on Network Computing and Applications (NCA), 2016 Most popular blockchain solutions, like Bitcoin, rely on proof-of-work, guaranteeing that the output of the consensus is agreed upon with high probability. However, this probability depends on the delivery of messages and that the computational power of the system is sufficiently scattered among pools of nodes in the network so that no pool can mine ...

A Circuit Approach to Constructing Blockchains on Blockchains [PDF]
arXivSince the creation of Bitcoin 15 years ago, there has been an explosion in the number of permissionless blockchains. Each of these blockchains provides an open ledger that anyone can read from and write to. In this multi-chain world, an important question emerges: how can we build a more secure overlay blockchain by reading from and writing to a given ...

Reward Distribution in Proof-of-Stake Protocols: A Trade-Off Between Inclusion and Fairness
IEEE Access, 2023 Proof-of-Stake (PoS) variants provide an energy-efficient alternative to Proof-of-Work (PoW). However, it is not clear whether practical PoS implementations are fair with respect to wealth, stake, and reward distribution.
