Secure and untampered voting.
In centralized server (server in AWS), the gate keeper can tamper the voting records (UPDATE voting set your_champion_voting = 100).
With smart contracts on top of Ethereum, that is impossible.
- jononor 9y agoThe important properties here are immutability, transparency and authentication. This could be done by a centralized server. For instance by keeping an append-only log with signed voting records which is regularly published, where each entry contains previous entry ID. Like git...
- langitbiru 9y agoBut how do you know that the centralized server does not override all records to tamper the evidence? Append-only log is useless if the actor choose to override all logs. So you need a neutral third party to keep the records in case the centralized server does the malicious behaviour. This can be done, I admit. But in a corrupt society, it is hard to find a neutral and trusted party. Other way is using blockchain to record the logs and incentivize the miners to maintain the nodes. You can not bribe the cryptography.
