BBFT: a Hierarchical Byzantine Fault Tolerant Consensus Algorithm ByStack Team v1.0 1 Introduction Consensus is the process applied by nodes to reach final agreement on network states. Byzantine fault tolerant (BFT) consensuses are considered well suited for permission-ed ...
A limited roadmap for the 2.0 Serenity upgrade that will switch Ethereum to Proof of Stake (PoS) from a Proof of Work (PoW) consensus protocol has been unveiled. The Ethereum ecosystem now has a timeframe to look out for starting later this year. The planned upgrade dubbed the fin...

With the emergence of blockchain technology, the decentralized cloud storage solutions are designed to revolutionize the way we store and share documents, pictures, and data. Storj, the leader in decentralized cloud storage, aims to o bring decentralized, end-to-end encrypted cloud storage to the ...
Thousands of blockchain projects with their corresponding crypto token have popped up since the birth of bitcoin in 2008, raising the question of interoperability between independent blockchains. Cosmos, a highly anticipated blockchain project, aims to provide a solution to improve the interoperab...
This infographic provides a schematic overview of the main Bitcoin-related “forks” that can happen and shows the most important forks that have happened. It does not provide an overview of all forks that have happened. What Are Bitcoin Forks? The word “fork” is somewhat confusing...
The first two Mimblewimble implementations - Beam and Grin have been receiving significant attention. As the most talked about privacy-oriented cryptocurrencies these days, the latecomers Beam and Grin are seen by some as the biggest competitor to Monero, the best-known privacy coin with the...
Abstract In 1985, FLP theory was proposed in a paper written by Fischer, Lynch and Patterson. FLP theory proves that in a completely asynchronous distributed system, no completely asynchronous consensus protocol can tolerate even a single unannounced process death. In 2002, Lynch ...
January 28, PlatON, the pioneering global privacy-preserving computing network has completed its Version 0.4.0 upgrade and began to support Verifiable Computation (VC) based smart contract. Since then, PlatON becomes the world’s first computing network uses the VC algorithms to build...
Algorand, the blockchain protocol founded by Silvio Micali, a Turing Award-winning cryptographer and professor of computer science at MIT, is undoubtedly among the most anticipated blockchain project in 2019. Sergey Gorbunov, chief cryptographer at Algorand that aims to solve the “blo...
