Block Structure

Block { Header { version: 4 bytes, prevBlockHash: 32 bytes, merkleRoot: 32 bytes, timestamp: 4 bytes, bits: 4 bytes, // Difficulty target nonce: 4 bytes // Mining counter }, Transactions: [ 1 to ~4000 TXs ], Block Size: up to 4,000,000 weight units }

The Mining Process

How energy is transformed into digital security through computational work.

Network Hash Rate
750
EH/s

Proof of Work Consensus

Bitcoin miners compete to find a nonce that, when hashed with the block header, produces a hash below the current difficulty target. This process requires significant computational effort and energy expenditure.

The first miner to find a valid hash broadcasts the block to the network, earning the block subsidy and transaction fees as a reward for their work.

Difficulty Adjustment

Every 2,016 blocks (~2 weeks), the difficulty retargets to maintain an average block time of 10 minutes, regardless of total network hash rate.

Protocol History

The development and milestones of the Bitcoin network since its inception.

2008
Whitepaper Published
Satoshi Nakamoto publishes "Bitcoin: A Peer-to-Peer Electronic Cash System" on the cryptography mailing list.
2009
Genesis Block
The Bitcoin network launches with the mining of the genesis block on January 3, 2009.
2010
First Transaction
Laszlo Hanyecz purchases two pizzas for 10,000 BTC, establishing Bitcoin's first real-world value.
2012
First Halving
Block reward reduces from 50 BTC to 25 BTC. Price begins a historic bull run.
2017
SegWit Activation
Segregated Witness activates, enabling Lightning Network and fixing transaction malleability.
