"SNARKs allow a Prover to prove to a Verifier that she/he has a solution W to the problem F with shared/known inputs X, without revealing W."
"Eric Budish, a Professor of Economics at the University of Chicago, recently published a working paper called “The Economic Limits of Bitcoin and the Blockchain,” in which he argues that the theoretical threat of a majority attack (a.k.a. 51% attack) in Bitcoin is much higher than we believe."
"One of FLETA’s major innovations to the blockchain space is the new and novel “Proof-of-Formulation” consensus algorithm that prevents forks by providing real-time confirmation of blocks and transactions."
"In a permissionless cryptocurrency network, peers must not be trusted. So, to prevent against resource exhaustion attacks, Bitcoin nodes first check the PoW for any received blocks before committing more resources, such as storing the block in RAM or on disk. However, it turns out that checking a Proof-of-Stake is a lot more complicated and context-sensitive than validating a Proof-of-Work."
"In order to help more people understand “the other Casper” (Vlad Zamfir’s CBC Casper), and specifically the instantiation that works best for blockchain protocols, I thought that I would write an explainer on it myself, from a less abstract and more “close to concrete usage” point of view."
"Liveness and safety are two inseparable properties of consensus protocols. Liveness is a guarantee that a protocol will do something useful even in the face of failures. CBC Casper, a family of consensus protocols, leaves out liveness from their analysis. Treating 1 out of 2 doesn’t get you 50% of the way to a full protocol; it leaves you with almost nothing."

"tl;dr: We examine the history and future of dust: containers (UTXOs) of bitcoin that cost more to spend in fees than they hold."
"This blog post is the first in the series of two on Blockchain Sharding. After reading this blog post you will know why Sharding is the path to the future-proof blockchain protocols, how Sharding is being built today, what challenges all the sharded protocols face, and how such challenges can be addressed"
"The crypto market is still inefficient. Cryptoassets have different rates on different exchanges. The big question is how we can profit from that inefficiency. One approach is making transactions between exchanges, but if we buy a cryptoasset on one exchange, by the time we can sell it on another, the price difference may no longer exist."

"A simplified overview of Correct-By-Construction Casper consensus mechanism"
Abstract: We present an in depth report into the cryptocurrency exchange ecosystem. The market is broken down by almost all the possible characteristics (Exchange type, exchange region and trading pairs). The robustness and authenticity of exchanges are evaluated using metrics such as web traffic, average trade sizes, order book depth, security polices and price reliability. The report was produced by CryptoCompare and uses the CryptoCompare’s Aggregate Pricing Index (the CCCAGG), for much of the analysis.
"The joint HM Treasury-Financial Conduct Authority-Bank of England Cryptoassets Taskforce report sets out the UK’s approach to cryptoassets and distributed ledger technology in financial services."
"This article will focus on the role that sidechains and sister chains play in the EOS ecosystem and will address some of the challenges that these projects face."
"Ultimate Guide to EOS Smart Contract Security. The crypto community became skeptical when the World’s biggest ICO, EOS launched in June 2018 and it got freezed out for 2 days due to a software bug. But fast forward 4 months and EOS today accounts for more than double the transactions that Ethereum does today. Through the promise of free and faster transactions, the topmost Dapp of EOS has about 13,000 daily active users compared to just 2,000 of Ethereum’s topmost Dapp."
The whitepaper. "We introduce a plasma sidechain designed specifically for non-custodial, high-speed, low-latency trading. We explore extending the value proposition of plasma to a financial institution using comprehensive set of fraud-proofs to enforce correctness and voting to handle data unavailability."
