Last updated: 16 March, 2018 Forks, or the threat of them, seem to be an established feature of the cryptocurrency landscape. But what are they? Why are they such a big deal? And what is the difference between a hard fork and a soft fork? A “fork,” in programming terms, is an open-source code modification. Read More

Last updated: 16 March, 2018 On August 1, 2017, the bitcoin protocol underwent a hard fork which split the network in two and gave birth to “bitcoin cash.” Why did this happen and what are the consequences? Tired of the infighting and perceived lack of progress on bitcoin’s scaling debate, and unhappy with the decision Read More

Last updated: 22 February, 2018 SegWit (short for Segregated Witness) is a protocol upgrade that changes the way data is stored.

A few years after Satoshi Nakamoto unleashed his bitcoin paper on the world, the cryptocurrency’s users began to notice a potential problem: bitcoin wasn’t very liquid. For a system that many claimed could replace fiat payments, this was a big barrier. While Visa handles around 24,000 transactions a second, bitcoin could process up to 7. Unless Read More

Hailed as one of the most potent solutions to cryptocurrency scaling currently under development, the lightning network effectively creates a layer on top of bitcoin, enabling fast and cheap transactions which can net settle to the bitcoin blockchain. Proposed by Thaddeus Dryja and Joseph Poon in a 2015 white paper, the idea is based on Read More

What is Ether?

5 months ago admin2 Comments Off on What is Ether?
As we explored in “What is Ethereum?”, ethereum aims to function both as a kind of decentralized internet and a decentralized app store, supporting a new type of application (a “dapp”) in the process. But while no one owns ethereum, the system that supports this functionality isn’t free. Rather, the network needs ‘ether’, a unique piece Read More

How Ethereum Mining Works

5 months ago admin2 Comments Off on How Ethereum Mining Works
Today, miners play an important role in making sure ethereum works. This role isn’t immediately obvious, though. Many new users think that the sole purpose of mining is to generate ethers in a way that doesn’t require a central issuer (see our guide “What is Ether?“). This is true. Ethereum’s tokens are created through the process of Read More

How Will Ethereum Scale?

5 months ago admin2 Comments Off on How Will Ethereum Scale?
Like other public blockchains, ethereum intends to support as many users as it can. The problem is that, today, we don’t really know the limits of the platform. Because of a hard-coded limit on computation per block, the ethereum blockchain currently supports roughly 15 transactions per second compared to, say, the 45,000 processed by Visa. This limitation Read More

What are Blockchain’s Issues and Limitations?
