Notes share block chain: technology and math:
- The reverse process of hash addition to high exhaustive, there is no more effective way, the process in the current computing power will inevitably time consuming. 2. asymmetric encryption, public key and private key signature scheme PoW:
[If! SupportLists] 1. [Endif] accounting adjustment once, get in line with the rules of work it takes.
[If! SupportLists] 2. [Endif] who computing faster, who will fight to the billing authority,
- For the hash symbol required, there will be conflict, how to solve? once the minimum effective? ? But who Arbitration A: Use the longest path 51% attack.
Who controls 51% of the calculated force, whoever controls the entire chain block
