Is Bitcoin a Layer 1 Blockchain?

Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain.

Bitcoin is unique in that there are a finite number of them: 21 million.

Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.

NOTE: WARNING: Bitcoin is not a Layer 1 blockchain. While it is based on blockchain technology, it is actually a Layer 2 solution that operates on top of a larger, underlying Layer 1 blockchain. Therefore, if you are seeking out a Layer 1 blockchain solution, then Bitcoin is not the right option for you.

As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.

Bitcoin is often called the first cryptocurrency, although prior systems existed and it is more correctly described as the first decentralized digital currency. Bitcoin is the largest of its kind in terms of total market value.

Bitcoin is a Layer 1 blockchain because it is a protocol that enables communication between different parties on the network. The Bitcoin blockchain does not have any built-in features or functionality beyond enabling these transfers of value or information from one party to another.
