What is the biggest blockchain company?
What it does: As mentioned earlier, IBM is the largest company in the world embracing blockchain. With over $200 million invested in research and development, the tech giant is leading the way for companies to integrate hyperledgers and the IBM cloud into their systems.
When did blockchain grow from 50gb to 100gb?
In August 2014, the bitcoin blockchain file size, containing records of all transactions that have occurred on the network, reached 20 GB (gigabytes). In January 2015, the size had grown to almost 30 GB, and from January 2016 to January 2017, the bitcoin blockchain grew from 50 GB to 100 GB in size.
