What blockchain technology aims to achieve was not new to us. It was in 2002 that we took on a project that Expanded Password System was incorporated in a private/public key scheme deployed in a decentralized P2P formation. We were not able to secure the further budget for commercial implementation and had to let it go; perhaps it was attempted too early.
As such we were probably among the very first to have noticed the value of the blockchain when it became known to the public, although we immediately rejected the current form of cryptocurrency built on blockchain as no more than a gamble.
We will be going to make secure the meaningful blockchain-applied solutions that are distinguished from the gamble of resource-wasting cryptocurrencies by having the cryptographic keys regenerated on-the-fly from our episodic memory.
