Bitcoin Gold replay protection
We'd like to clear up a few misconceptions for those in doubt about what, exactly, the Bitcoing Gold replay protection (or lack thereof) really means.
There is no Bitcoin Gold ...

The main idea behind BetterHash is to improve decentralization of Bitcoin mining ...
ELI5 Cryptocurrency Sharding
If you come from the world of IT, then you've probably heard of database or disk data sharding.
For those who don't come from IT, a real simple way to put it is that sharding m...
Proof of Authority (PoA) Summary [Cryptocurrency consensus mechanisms]
Proof of Authority is a consensus mechanism where members of a cryptocurrency network are identified and receive delegated powers to solve blocks. If they defraud the system their identity is at stake and they will either be prosecuted or booted from the network. This is a centralized system where a higher authority delegates mining powers […]
Proof of Capacity (PoC) Summary [Cryptocurrency consensus mechanisms]
Proof of Capacity (PoC) consensus algorithms require network participants to prove they have performed a certain amount of storage operations in order to mine a valid block. Where Proof of Work consensus requires users to prove they have performed computations in time (to guarantee a 10 minute space between Bitcoin blocks, for example), Proof of […]
Proof of Activity (PoA) Summary [Cryptocurrency consensus mechanisms]
Proof of Activity (PoA) is a cryptocurrency consensus mechanism which combines Proof of Work (PoW) and Proof of State (PoW) into a hybrid mining system. In a PoA system, validators begin by applying a Proof of Work stage to block headers until they find a desirable hash. The block headers are then passed onto a […]
Opinion: Decentralized blockchains can only survive having a valuable token, like Bitcoin, attached to them [Feb 2018]
We’ve heard this time and again, especially from folks in the financial sector: “blockchain is here to stay, Bitcoin not so much”. Is this really so? We disagree, and in this article we discuss the origins of Bitcoin and how the problem it solved only makes sense when there’s a reward for participants to join […]
Concepts In This Page
A process or system by which multiple parties are able to reach consensus. In the context of cryptocurrencies, it's the process which allows for everyone to agree on everyone else's money balance. E.g. Bitcoin employs Nakamoto consensus via PoW mining.
Ethereum Virtual Machine (EVM)
The Ethereum Virtual Machine (EVM) is the individual component which enables the worldwide decentralized computing infrastructure on the blockchain. Smart contracts actually run on each individual EVM instance around the world. Miners verify and store results from EVM computing processes on the blockchain.
