Bitcoin Core is an implementation of bitcoin. Initially, the software was published by Satoshi Nakamoto under the name "Bitcoin", and later renamed to "Bitcoin Core" to distinguish it from the network.
Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full node. It does not facilitate the buying or selling of bitcoin. It allows users to generate QR codes to receive payment. The software validates the entire blockchain , which includes all bitcoin transactions ever. This distributed ledger which has reached more than gigabytes in size must be downloaded or synchronised before full participation of the client may occur.
It also provides access to testnet, a global testing environment that imitates the bitcoin main network using an alternative blockchain where valueless "test bitcoins" are used. Regtest or Regression Test Mode creates a private blockchain which is used as a local testing environment. Checkpoints which have been hard coded into the client are used only to prevent Denial of Service attacks against nodes which are initially syncing the chain.
For this reason the checkpoints included are only as of several years ago. This limited the maximum network capacity to about three transactions per second. A network alert system was included by Satoshi Nakamoto as a way of informing users of important news regarding bitcoin. It had become obsolete as news on bitcoin is now widely disseminated. Bitcoin Core includes a scripting language inspired by Forth that can define transactions and specify parameters.
Two stacks are used - main and alt.
