Free Public API for Bitcoin Chain

Launched in 2009, Bitcoin blockchain is a decentralized and immutable ledger that underpins the entire Bitcoin ecosystem, recording all transactions in a chronological order, secured through a combination of cryptographic principles, decentralized consensus mechanisms, and economic incentives. It enables trustless peer-to-peer transactions, facilitating global transfers of value without intermediaries.

Bitcoin Mainnet

Bitcoin Mainnet is the primary network where Bitcoin cryptocurrency transactions occur and are recorded on the blockchain. It serves as the definitive ledger for Bitcoin ownership and transfers, maintained by a decentralized network of nodes running the Bitcoin protocol. The mainnet is where miners validate and add new transactions to blocks, securing the network through the proof-of-work consensus mechanism.
