The Blockchain Anomaly

open access: green2016 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 ...

Scalable Multi-Chain Coordination via the Hierarchical Longest Chain Rule [PDF]

open access: yes2022 IEEE International Conference on Blockchain (Blockchain), 2021
This paper introduces BlockReduce, a Proof-of-Work (PoW) based blockchain system which achieves high transaction throughput through a hierarchy of merged mined blockchains, each operating in parallel on a partition the overall application state. Most notably, the full PoW available within the network is applied to all blockchains in BlockReduce, and ...
