WHAT IS BITCOIN?

Bitcoin is a Distributed Ledger Technology (DLT) or Blockchain, in which copies of accounting records are distributed and validated by a multi-user consensus process that independently verifies changes in accounting.

Bitcoin Technology (DLT) consists of three parts: cryptography, block chain and distributed consensus network (p2p network). Each of these components serves a specific purpose:
Cryptography provides a mechanism for secure coding of protocol rules in the system and is used to prevent tampering, theft or wrong input of information to the platform, as well as for the generation of encrypted digital signatures and identities.

The block chain is a public and distributed database in which the transactions performed on the network are securely recorded.

The distributed consensus is the performance of the participants of the network verifying and confirming the certainty and uniqueness of the transactions to generate an irrefutable truth about them in the peer-to-peer (p2p) network.

Later, Nakamoto left the project and left it in the hands of a group of developers that is currently known as Bitcoin Core. Wladimir J. van der Laan, Gavin Andresen, Peter Todd, Jeff Garzik, Gregory Maxwell, Pieter Wuille and Jonas Schnelli are some of the most outstanding developers of this team and who manage the progress of the original Bitcoin code.
