Proof of work is scam, claims Peter Schiff in his latest crypto critique origin »
Proof of stake (PoS) is an inferior consensus protocol to Proof of Work. It’s chosen by cryptocurrency founders as a way to decide which user or users can validate new blocks of transactions, without being constrained by a physical cost.

The former JPMorgan executive believes that the Proof of Work is a feature. He pointed out that Kadena is not ready to move away from the Proof of Work mechanism yet. We were very thrilled by the fundamental design of Bitcoin, the CEO added.

If you solved a really complicated math problem all by yourself, you’d obviously want credit for it. This is the central idea behind “proof of work,” the consensus mechanism that powers Bitcoin and a number of other assorted cryptocurrencies.

A recent study by the Bank of Canada has found that double spending on Proof of Work [PoW] blockchain is an “unrealistic” outcome. This is modeled on the behaviors of an “honest miner” and “dishonest miner”.

A new study sponsored and published by the Bank of Canada on the “incentive compatibility” of blockchain technology realizes that back-channel effort and double spending is arguably “unrealistic.

Proof of Work (PoW), Proof of Stake (PoS), and Proof of Assignment (PoA) are cryptocurrency mining protocols. Essentially, they are computer algorithms that allow cryptocurrencies to function. If you’ve been following the crypto world, then you’re probably already familiar with the two main protocols known as PoW and PoS. As it stands, there are […]

Although the ideas behind the current Ethereum protocol have largely been stable for two years, Ethereum did not emerge all at once, in its current conception and fully formed. Before the blockchain has launched, the protocol went through a number of significant evolutions and design decisions.

Special thanks to Eli Ben-Sasson for ongoing help, explanations and review, coming up with some of the examples used in this post, and most crucially of all inventing a lot of this stuff; thanks to Hsiao-wei Wang for reviewing Hopefully many people by now have heard of ZK-SNARKs, the general-purpose succinct zero knowledge proof technology that can be used for all sorts of usecases ranging from verifiable computation to privacy-preserving cryptocurrency.

Special thanks to Eli Ben-Sasson for ongoing help and explanations, and Justin Drake for reviewing In the last part of this series, we talked about how you can make some pretty interesting succinct proofs of computation, such as proving that you have computed the millionth Fibonacci number, using a technique involving polynomial composition and division.

Most people are familiar with bitcoin’s Proof of Work (PoW) consensus, and Proof of Stake (PoS). Yet, there other consensus types like the Proof of Authority (PoA), which is a relatively new consensus.

Nonprofit organization PoWx has launched this week with the goal of boosting the idea behind proof of work (PoW) through more innovative algorithms. The company is seeking to decentralize Bitcoin mining and make it more accessible to consumers through a new technology that executives have dubbed “optical PoW” — a new type of hardware that utilizes a more advanced and energy-efficient form of laser technology as the cornerstone of mining.

As his Hungarian parents had fled post-war Soviet regime to settle in the United States, Nick Szabo came to call the Californian Bay area of the 1990s his home. Here, he was among the first to frequent the in-person “Cypherpunk” meetings organized by Timothy May, Eric Hughes and other founding members of the collective of cryptographers, programmers and privacy activists centered around the ’90s mailing list of the same name.

Elrond Network is a scalable public blockchain that seeks to deploy a novel architecture that goes beyond typical scalability with their whole state sharding scheme. The sharding protocol eliminates energy and computational waste while also ensuring there is fair distribution through the Secure Proof of Stake (SPoS) consensus. Still, the structure will work in line […]

Last year, growing problems of Bitcoin mining centralization came to light with the controversy of an AsicBoost scandal. As a largely centralized hash rate began to threaten the software’s magical property, concerns were raised that incentives at the crux of Bitcoin’s game theory had broken away.

By rights, it ought to be impossible to double spend tether, but that’s what happened on June 28 according to one Chinese cybersecurity firm. Someone sent 694 tether to an exchange and was credited

Recently I had the fortune to have received an advance copy of Eric Posner and Glen Weyl’s new book, Radical Markets, which could be best described as an interesting new way of looking at the subject that is sometimes called “political economy” - tackling the big questions of how markets and politics and society intersect.
