Protocols

Links to the best articles, videos and podcasts about blockchain and cryptocurrency Protocols.

MimbleWimble

"MimbleWimble is a privacy-enhancing and scalable blockchain protocol. It verifies that all transactions are valid without storing the blockchain’s entire history."

The Defensibility of Middleware Protocols

"While not a perfect mapping to traditional use of the term middleware, these protocols can be thought of as anything sitting just below the interface layer (i.e., the applications the end user interacts with), but leveraging the lower-level functionality provided by layer-1 blockchains and interoperability protocols."

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."

Taproot Is Coming: What It Is, and How It Will Benefit Bitcoin

"Bitcoin users may, before long, be able to benefit from a trick called “Taproot.” First proposed by Bitcoin Core contributor and former Blockstream CTO Gregory Maxwell, Taproot would expand on Bitcoin’s smart contract flexibility, while offering more privacy in doing so. Even the most complex smart contracts would, on the blockchain, typically be indistinguishable from regular transactions."

BetterHash Protocol Lets Pool Miners Regain Control Over Their Hash Power

"One problem that concerns many is the centralization of mining within the Bitcoin ecosystem. Fortunately, there are talented developers working to solve this problem and Matt Corallo, full-time Bitcoin developer at Chaincode Labs, is one of them. His BetterHash Mining Protocol is intended to significantly decrease the problems associated with mining pool centralization."

Sharding: What it is and why many blockchain protocols rely on it

"Sharding is one of several popular methods being explored by developers to increase transactional throughput."

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."

Introducing P4: Private Periodic Payment Protocol

"Least Authority has recently designed a protocol called the Private Periodic Payment Protocol, or P4, which aims to define the way in which subscription services can be funded using end-to-end private cryptocurrency payments."

“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 Primer on Blockchain Interoperability

"Distributed systems have to make trade-offs to function effectively in an asynchronous environment like the internet — one without a global clock to define the ordering of events. Blockchain-based networks, designed to carry immense value, must also guard against malicious, or byzantine, actors."

Introducing PoB — How to design a more decentralized consensus

"IOST’s consensus algorithm — PoB — includes a more decentralized committee election process than current DPoS systems while still maintaining the scalability benefits and censorship resistance."

Ethereum Plans to Cut Its Absurd Energy Consumption by 99 Percent

"The cryptocurrency is going on an energy diet to compete with more efficient blockchains"

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."

The Moloch DAO: Collapsing The Firm.

"In this article, I will detail thoughts around the Moloch DAO. It’s a new type of organisation (developed by Ameen Soleimani, Arjun Bhuptani, James Young, Layne Haber & Rahul Sethuram) that blurs and redefines the definition of a firm."

Fundamentals of Proof of Work

"In the anonymous, unregulated Internet, participants are free to act as economic agents, often with few consequences for deviant behavior. Instead of assuming that greater than 51% of all actors will be acting honestly, Bitcoin assumes that greater than 51% of all actors will be acting according to their best economic interest."

The Lightning Network

"In this post, we’ll explore the Lightning Network (LN): what it is, how it works, what makes it special, what tradeoffs it makes and some of the weaknesses it has."

The authoritative guide to Blockchain Sharding, part 1

"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"
