Bitcoin blockchain file sizes, which contained all transactions and information on the community, continued to develop considerably. By August 2014, it had reached 20 gigabytes, and finally Home Improvement News exceeded 200 gigabytes by early 2020. Most cryptocurrencies use blockchain technology to report transactions. For instance, the bitcoin network and Ethereum network are each based mostly on blockchain. On eight May 2018 Facebook confirmed that it might open a brand new blockchain group which might be headed by David Marcus, who previously was in control of Messenger.
