Bitcoin Blockchain Size Growth: Understanding the Expansion

cosino

The Bitcoin blockchain size growth refers to the continuous increase in the total data stored on the Bitcoin network. This growth is driven by the addition of new blocks containing transaction data, which are added approximately every 10 minutes. As more users join the network and conduct transactions, the blockchain size expands, currently exceeding hundreds of gigabytes. This growth impacts storage requirements for nodes and can influence network performance and decentralization.

Factors contributing to this growth include higher transaction volumes, block size limits, and the immutable nature of the ledger. Solutions like Segregated Witness （SegWit） and layer-2 protocols have been introduced to manage this expansion efficiently.
