Can I ask what does a fourth generational blockchain mean? really im not too familiar with these techy terms... is this referring to a DAG? like hashgrash or something??
Correct me if i'm wrong.
1st gen: PoW coins. Very slow.
2nd gen: smart contracts. Faster but not enough, at least for now.
3rd gen: Solved scalability issues.
4th generation protocol theoretically should combine all the features of previous blockchains. i.e. lightning speed + complex data + smart contracts.
