know who is hosting the nodes, so it is not easy to attack the network. In a "centralized Blockchain", an attacker knows what
organization to target, so it is not that difficult to compromise the whole organization, even if the nodes are decentralized.
distributed and centralised are 2 things but it gets complicated.
1)say bitcoin was on 5 computers all held in 1 office. but each computer was password by 5 strangers who do not talk to each other and turn up on separate days to never meet..
2)say bitcoin was on 5 computers held in 5 locations. but each computer was password by 5 strangers who do not talk to each other and never meet..
3)say bitcoin was on 2000 computers held in 2000 locations. but all distributed by one person to his desired location. he visits each location to maintain them
4)say hyperledger was on 5 computers held in 1 office. but each computer was password by 5 strangers who do not talk to each other and turn up on separate days to never meet..
5)say hyperledger was on 5 computers held in 5 locations. but each computer was password by 5 strangers who do not talk to each other and never meet..
6)say hyperledger was on 2000 computers held in 2000 locations. but all distributed by one person to his desired location. he visits each location to maintain them
now... here is the next conundrum
a)all 5 bitcoin nodes are pre programmed by 1 person, all the software, rules, are done by one man that handed it to 5 people
b)all 5 bitcoin nodes are pre programmed by 5 different people, all the software, rules, are done by the programs (not people) finding a fair consensus that all 5 nodes can tolerate.
c)all 5 hyperledger nodes are pre programmed by 1 person, all the software, rules, are done by one man that handed it to 5 people
d)all 5 hyperledger nodes are pre programmed by 5 different people, all the software, rules, are done by the programs smart contract ability to cross communicate/translate/redefine
now. list the numbers that are technically not 'centralised'
