Transaction privacy is a fundamental requirement for many kinds of financial services, and the inability to provide this privacy has prevented Ethereum from providing compelling alternatives to traditional financial instruments. There are several blockchains and blockchain projects that use cryptographic techniques to provide this privacy, but this privacy is reserved for the ‘native’ cryptocurrency of… Read More


The recent low in cryptocurrency morale has given our community a rich opportunity for reflection. The vast majority of us crypto enthusiasts have a genuine heart for marrying technology and social action, and I believe it’s time we reflect on where we wanted to go with digital currencies, honestly take stock of the state of… Read More


What are the flaws inherent in both Proof-of-Work and Proof-of-Stake that make Proof-of-Signature an ideal alternative? A short explanation is given below. How does Bitcoin validate transactions and deter denial of service attacks? It requires a transaction-requesting entity to perform computational work. Inessence, it makes data creation difficult for users but data verification easy for… Read More


Although more casual, less-technical crypto-enthusiasts might not know much on this topic, an essential aspect of any cryptocurrency project is the consensus algorithm that it utilizes. These algorithms accomplish two major objectives. Firstly, it ensures that the next block in a blockchain is the true, master-version of the details. Secondly, it makes sure that those… Read More


Over the last few years, there’s been a lot of projects, both public and private, that are attempting to create a next-generation blockchain or something better than Satoshi’s Bitcoin. A great majority of these projects have condemned proof-of-work (PoW) cryptocurrencies because they think they waste resources, and many of these new blockchains have chosen to… Read More


Malta, an island nation in the Mediterranean Sea, is completing the first ever attempt by a nation state to tie citizen records to the blockchain. If successful, a scaled-up version of the pilot program will give Malta’s 400,000 residents the ability to retrieve and share educational records and transcripts for free. What’s more, it wouldprovide… Read More


Security researchers have discovered a series of new vulnerabilities in EOS blockchain platform, one of which could allow remote hackers to take complete control over the node servers running the critical blockchain-based applications. EOS is an open source smart contract platform, known as ‘Blockchain 3.0,’ that allows developers to build decentralized applications over blockchain infrastructure,… Read More


This is not about archival nodes. This is about about staying in sync, after the fact. My Argument: Ethereum’s runaway data directory size is just the tip.My Prediction: It will all work, until it doesn’t.My Suggestion: Transpose.

It should be acknowledged that if database coordination and more efficient allocation of code is the desired functionality of a system, then blockchain may not necessarily be the solution for which an organization is looking. Distributed ledger technology (DLT) systems like IBM Fabric or R3 Corda are capable of similar functionalities as blockchain systems, but… Read More
