Blockchain is the technology supporting the process of mining and pricing bitcoins, a procedure whereby the users of this cryptocurrency make payments and transactions in an encrypted and authenticated form on a distributed database.
Any issue related to bitcoins is invariably linked to blockchain , the technology on which the cryptocurrency is based. The end result is a huge database distributed in numerous servers all around the world that gathers all the transactions made in bitcoins.
Each one of these operations, encrypted and authenticated, is added to the chain of blocks —or blockchain— on which bitcoins are based. This process would be impossible without APIs.
The fact is that today, bitcoin technology offers many more possibilities and arouses more interest among developers than other online payment systems such as PayPal, for example. Currently within the collaborative development platform GitHub there are almost 3, repositories linked to PayPal , whereas there are over 8, repositories linked to bitcoin.

What you have to take into account is that every transaction a user makes with bitcoins —once verified— is added to the blockchain, and at that precise instant it begins to form part of a shared accounting system.
This blockchain or shared accounting system is the result of all the transactions made with bitcoin wallets by all the users on the Internet. Each transaction requires a code and a signature that identifies each user and encrypts and verifies each transaction. Each transaction enters the blockchain through a process known as bitcoin mining, based on a procedure known as proof of work POW.
Each transaction, which is always public, must be verified to avoid problems within the blockchain: bitcoins must be authentic and not duplicated. Otherwise, someone loses money. The idea is that a series of nodes are responsible for verifying the authenticity of each transaction, a protocol that usually takes 10 minutes. It is reevaluated every blocks, so the process always takes around that time to verify.
The idea is that each transaction is verified by consensus, and the transaction authentication process receives a commission through the proof of work. This system avoids violations without having to depend on a trustworthy arbiter for example a bank. Some of the key characteristics of the blockchain platform :.

Each wallet is associated to a password with a minimum length of 10 characters, an authentication code for the API, a private code for each user, the folder where the wallet is created, and an e-mail address. It can be installed and used from libraries in numerous programming languages: syntax such as Python , Ruby , PHP , Node. How does blockchain work?
