ELI5 PSBT – Partially Signed Bitcoin Transactions
Trustless operation is one of the key concepts behind cryptocurrencies. The idea is that you should not have to personally meet, or trust your peers, in order to perform successful transactions. Experienced crypto users may take this concept for granted, but come to think of it – every real world transaction before cryptocurrencies came about […]
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 Location (PoL) Summary [Cryptocurrency consensus mechanisms]
In a Proof of Location consensus algorithm, users’ geospatial coordinates are accounted for as proof of value. This kind of algorithm is usually employed in cryptocurrency geomining systems. In a geomining application, users earn rewards for being at a certain place at a certain time. If, for example, a company wished to gather participants for […]
Will Bitcoin lose its #1 market cap crown?
Ethereum has just overtaken Bitcoin! But, wait! We’re not talking about market cap… As you’ve probably seen reported elsewhere, ETH now (Jun/2018) has more unique active addresses than Bitcoin.

A Bitcoin Puzzle is a cryptographic puzzle which carries Bitcoin as a reward. Those able to break the cryptography obtain access to the private key needed to unlock the Bitcoin.
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.
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.
A distributed ledger is a decentralized financial database with data stored across multiple locations.
Hal Finney was a cryptographer who pioneered the development of Bitcoin. Finney received the first ever Bitcoin transfer.
Public Key Encryption
Public Key Encryption is an encryption method by which the encoding and decoding keys are different. AKA asymmetric encryption. Examples include RSA and elliptic curve cryptography (the latter used in Bitcoin and most cryptocurrencies).
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.
