The Blockchain is Coming
Satoshi Nakamoto published the original paper on Bitcoin in 2008 and released the first software implementation in 2009. By 2011 the Bitcoin Core was being run by a group of developers who had worked with him. His current known holdings of Bitcoin are valued at over 500 million USD. At this stage the actual identity of Satoshi is perhaps the biggest mysteries in technology.
Despite this mystery, Blockchain, the technology underlying Bitcoin has been universally accepted as truly transformational. In the absence of any centralised leadership structures, Bitcoin itself has come up against the problems of scaling and speed and there are no immediate signs of resolution. On the other hand, every institution with a technology vision is now involved in examining options for its use.
For sure, the concept of a Distributed Ledger to record transactions with almost no chance of corruption or repudiation is totally at variance to any structures of Trust that the world currently knows. Therefore, while the use cases are obvious and many, it will be some time before existing organisations and systems adapt. The infographic from PwC is quite helpful in understanding the business architecture for a Blockchain application.
Meanwhile, Bitcoin is spreading but the main usage seems to be for payments where the buyer and seller want to hide their identities. It would appear that crime drives technology much more than more virtuous causes.
