=== Bitcoin's Test Blockchains
You might be surprised to learn that there is more than one bitcoin blockchain. The "main" bitcoin blockchain, the one created by Satoshi Nakamoto on January 3rd, 2009, the one with the genesis block we studied in this chapter, is called _mainnet_. There are other bitcoin blockchains that are used for testing purposes: at this time _testnet_, _segnet_ and _regtest_. Let's look at each in turn.

You can also run on testnet3 with other full-node implementations, such as +btcd+ (written in Go) and +bcoin+ (written in JavaScript), to experiment and learn in other programming languages and frameworks.
In early 2017, testnet3 supports all the features of mainnet, in addition to Segregated Witness (see <<segwit>>), which has yet to activate on mainnet. Therefore, testnet3 can also be used to test Segregated Witness features.
