Swarm — Distributed Pre-Image Archive (DPA)

"Today, we’ll look at the DPA layer of Swarm, which is responsible for parcellating files into chunks and putting them back together, along with encrypting & decrypting them. In this blog, I will try to depict these four functionalities and the inner workings of the DPA. The image below shows where the DPA fits in the Swarm architecture."

Reverse Convertibles—Complex Investment Vehicles

"Although often described as debt instruments, they are far more complex than a traditional bond and involve elements of options trading. Reverse convertibles expose investors not only to risks traditionally associated with bonds and other fixed income products—such as the risk of issuer default and inflation risk—but also to the additional risks of the unrelated assets, which are often stocks."

Transacting Bitcoin-based P2P Derivatives

"A forward contract is a type of derivative that represents a bilateral agreement to buy or sell an asset at a specific price (the “forward rate”) at a predetermined date in the future, usually to strategically hedge against price changes. The forward rate is a mutually agreed upon fair price at settlement, that takes into account factors like the spot price at the creation of the contract, growth from interest rates, and cost of storage. Forward contracts are handled between two parties, usually without the need for an exchange or clearing house, so both parties must trust each other to meet the terms of the agreement."

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 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."

“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."
