  • Bitcoin Blockchain Grows to 300 Gigabytes in Size

    The size of Bitcoin’s whole network — which full nodes need to synchronize — has reached a new milestone.

    The size of the full Bitcoin blockchain exceeded 300 gigabytes of data on September 19, according to

    This is the size of the full Bitcoin transaction history for the past 10 years. It’s also the amount of information full mining nodes need to download and keep on their hard drives after synchronizing with Bitcoin’s network.

    While this amount of data might seem significant, a terabyte hard drive would easily cover it—and continue to do so for another decade or two. In contrast, an archival node on the Ethereum blockchain is already over five terabytes in size—and increasing at record speeds with growing block sizes—although a pruned node comes in at just 165GB.

    But the Bitcoin blockchain has been growing at a faster rate over the last few years—as opposed to its early days. This is largely due to an increase in the number of transactions being made on a daily basis and the introduction of scaling solution SegWit, which effectively doubled block sizes to two megabytes.
