now you are saying blockchain is not innovative, cause blockchain is nothing new, it exists since around 1991
That's not what I'm saying.
The first blockchain was conceptualized by a person (or group of people) known as Satoshi Nakamoto in 2008.
https://en.wikipedia.org/wiki/Blockchainwhich encryption techniques? i am pretty sure nothing on the blockchain is encrypted
I'm pretty sure you're wrong.
Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree.[3] Each block includes the cryptographic hash of the prior block in the blockchain, linking the two.
https://en.wikipedia.org/wiki/Blockchainah come on - throwing wikipedia links at me... tell me where the encryption happens on the blockchain and try to find other sources of blockchains and you will find that at least one blockchain was around in 1991
