The press service of the Documenting Bitcoin account published a message on social network X, stating that the entire Bitcoin blockchain can fit on an SD card. Experts noted that this is because storing all network transactions requires storage capacity of only a few hundred gigabytes.
The efficiency of data storage allows for the use of compact devices such as solid-state drives or microSD cards, making the blockchain portable and accessible for verifying operations with a full node on hardware with limited storage capacity.
The structure of the Bitcoin blockchain, based on a linked list of blocks and cryptographic hashes, ensures data integrity and chronological order, which is crucial for the security of BTC transfers without relying on a centralized authority.
The size of the Bitcoin blockchain remains manageable due to the protocol's predetermined block size limit, allowing it to maintain its compactness and decentralization even with increasing transaction volumes.
Experts emphasized that the ability to fit the Bitcoin blockchain on a small device underscores the network's efficiency and provides security, decentralization, scalability, and accessibility for users worldwide.
