Are Ethereum Full Nodes Really Full? An Experiment.

"A recurring Ethereum discussion topic is the storage requirements for running an Ethereum node. Some will say that an Ethereum node uses several terabytes of storage while others insist that it is much less."

Basic Attention Token (BAT)

"Digital advertising is broken. The marketplace for online advertising, once domi-nated by advertisers, publishers and users, has become overrun by “middleman” adexchanges, audience segmentation, complicated behavioral and cross-device usertracking, and opaque cross-party sharing through data management platforms.Users face unprecedented levels of malvertisements and privacy violations."

The Rainbow Network: An Off-ChainDecentralized Synthetics Exchange

"This paper presents the Rainbow Network, a design for an off-chainnon-custodial exchange and payment network supporting any liquid asset.The Rainbow Network allows a user to trade, lend, borrow, send, andreceive any liquid asset, entirely off-chain, while having only one on-chainpayment channel collateralized by a single asset."

A look inside iqlusion’s Cosmos Hub Validator architecture

"In this post, we’d like to provide a deep dive into how we built our Cosmos validator, the experiences that shaped our decisions, and hopefully offer some general insights into how to build a high availability datacenter networks and hybrid clouds in general."

How Ethereum can scale with SNARKs 101

"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."

A Review of Budish’s 51% Attack Theories - What is the Fair Price of An Old ASIC?

"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."

Breaking Down FLETA’s Proof-of-Formulation

"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."

“Fake Stake” attacks on chain-based Proof-of-Stake cryptocurrencies

"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."

A CBC Casper Tutorial

"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."

Peer Review: CBC Casper

"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."

Unsolved Problems in Blockchain Sharding

"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"

An Efficient Algorithm to Exploit Arbitrage Opportunities in Crypto Markets

"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."
