Bitcoin

Bitcoin is a Cryptocurrency. A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.

The OpenStreetMap project also accepts bitcoin donations.

Bitcoin the currency (XBT) can be used via a variety of payment methods at an increasing number of places. These methods are:

• On-chain - Transactions on the Bitcoin blockchain. These are known as Layer 1 transactions. Transactions are relatively slow and relatively expensive.
• Off-chain - Transactions on payment layers that connect to, but sit above the Bitcoin blockchain. These are known as Layer 2 transactions. An Example of a Layer 2 network is the Lightning Network. Lightning transactions are instant, low cost and suitable for small retail purchases, such as buying a cup of coffee.
