How can I sell Bitcoin?
There are many ways in which you can sell your Bitcoins. Over the counter (OTC) trade is growing everywhere, thus fulfilling one of Satoshi’s original ideas, which was to have a 100% decentralized P2P currency. There are also many centralized exchanges where you can safely trade your BTC for other cryptos, or even cash. In […]
Proof of Space (PoSpace) Summary [Cryptocurrency consensus mechanisms]
Proof of Space uses hard disk space as the value used to guarantee a participant’s stake in mining. By allocating disk space, the network participant provides value to the network, which uses this space to solve computational problems. Given low network bandwidth for a lot of regions, making it difficult to transfer large amounts of […]
Proof of Burn (PoB) Summary [Cryptocurrency consensus mechanisms]
In the Proof of Burn (PoB) consensus mechanism, miners earn the right to mint the next block by burning some value in the blockchain. All proof systems are based on the principle that minting a block must incurr in some cost, otherwise fraudsters could inject invalid transactions into the blockchain. Bitcoin achieves this by making […]
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 […]

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.
Cryptocurrency Transactions (TX's) are the logical object which tie an unspent output to a new input, forming the chain which allows us to control address balances. Transactions are grouped into blocks which, when verified by mining or staking, form the blockchain.
A concept of value exchange that does not require physical tokens (coins or paper cash) to be used in order to trade. Cryptocurrencies are a type of digital money.
Elon Musk is a serial entrepreneur who co-founded innovative companies such as Paypal, Tesla and SpaceX. His ambitious projects and impressive technical feats have catapulted him to the helm of business innovators.
HashCash is an early Proof of Work (PoW) system developed by Adam Back. Its initial purpose was to fight email spam, but HashCash ended up becoming a central component of the Bitcoin consensus mechanism.
