Bitcoin is an example of which type of blockchain?
Answers
Public Blockchain
Here are the three things you need to remember that define a public Blockchain.
(1) Anyone can download the code and start running a public node on their local device, validating transactions in the network and participating in the consensus process. This gives anyone the right to participate in the process that determines which blocks get added to the chain and what the current shape and size of the Blockchain is.
(2) Anyone can transact in the network. The transactions should go through as long as they are valid.
(3) Anyone can access and read transactions using a block explorer. Transactions are transparent but anonymous.
Several state-of-the-art public Blockchain protocols based on Proof of Work consensus algorithms are open source and not permission. It simply implies that anyone can participate, without permission. Examples include Bitcoin, Ethereum, Monero, Dash, Litecoin, etc.
