Consensus algorithm is a process to find an agreement on some data value involved in an operation.

A blockchain network consists of nodes that exchange data. They’re not controlled by anything so these exchanges have to be real in order to maintain a network as it was designed.

The main concern is that a node can send false data and if there are no nodes to verify it then a whole chain is under the risk of attacks. That’s why consensus algorithms are used.

For example, 51% attack. 51% attack means 51% of a chain is centralized and those who have access to nodes can change data. Therefore decentralization is so important.

There are a lot of algorithms which offer different ways to fix vulnerabilities but all of them have their own pros and cons.

There is a number of blockchain consensuses. However, one discussion receives a lot of public attention: it is the one about two mechanisms that are working shoulder-to-shoulder, but standing face-to-face. Today we want to place Proof of Work vs. Proof of Stake in the spotlight and to reflect on their pros and cons.

Both the mechanisms validate the transactions in the network: in PoW — by the computers and in PoS — by the owners of the currency.

Surely, much of the discussion wouldn’t be raised around the difference between these two for only one reason. Thus, there’s something else…

The general definition of a fork is to develop a new product using a part of code from another software.

Forks in cryptocurrencies can be hard or soft. A soft fork means a new version of the software but both versions are compatible. A hard fork means old versions and the new version won’t be compatible.

Everyone with programming skills can make a fork of any cryptocurrency (if its code is open), but the difficulty is that you need to find support in crypto community because almost all forks are less popular than original coins. For example, if no exchanges…

Cryptocurrency made a long way through various myths and illusions to finally reach even the government meetings. The main reason for that is blockchain — a decentralized ledger where each and every transaction is recorded.

Lots of users run mining programs on their home PCs.

Is it dangerous for your PC?

EOS.IO protocol has initially been invented by the company block.one in the middle of 2017. CEO of the company, Brendan Blumer is a 32 years old entrepreneur, executive, and investor based in Hong Kong. Brendan and Daniel Larimer, CTO of company, are the key people for EOS. The release date of EOS.IO was 31 January 2018.

An interesting fact is that during the initial coin offer of EOS (the native coin of EOS.IO) investors bought about 4$ billion worth tokens, so EOS ICO is the most successful ICO ever.
EOS.IO is based on a Delegated Proof of Stake (DPOS) algorithm. Block.one…

Overclocking is setting any characteristics of your hardware higher than that intended by the manufacturers. This can help you to improve performance in almost all tasks.

What parts you can overclock?

1. CPU
2. GPU
3. RAM (no sense for mining purposes)

Main principles of overclocking.

The first thing you need to know before overclocking is a multiplier and…
