Wallet address to wallet address crypto transfers would be orders of magnitude better than fiat payments if a reputation system were built in. Outside of blockchain it is impossible to embed reputation in payments. This blockchain advantage has never been leveraged. Until now. Until State Channels?
- Bob sends Alice 1 ETH via a smart contract;
- Alice receives a notification about the payment but she cannot access it until a rating is provided by Bob.
- Bob cannot provide a rating until Alice approves the payment. The notification she received asks her to approve the payment. She approves it.
- Once approved by Alice, Bob cannot retrieve his ETH from the smart contract.
- Bob is notified that Alice has approved the payment but that he must rate the transaction, for example, 1-5. Maybe Bob was buying a car and the exchange is happening in person. Bob is satisfied that all is in order and gives Alice a 5 rating.
- Once rated, Alice needs to rate Bob in order to access the 10 crystals. She rates bob 5. The ETH are now available to her in her wallet.
- An online market place is created. Reputation scores and Ethereum addresses of sellers are displayed. 50% of the purchases are conducted face to face and the reputation scores ensure a level of safety that buyers did not before have. Where the items need to be shipped, usually, if the buyer has a high reputation, the seller is content to accept the payment and ship in the knowledge that the buyer cannot access the paid funds.
To prevent people gaming the reputation system in order to abuse it, reputation given could be weighted depending on the reputation of the account giving it. For example, a reputation score given by an account with established reputation achieved through multiple transactions would increase the recipient’s reputation score more than that received from a new account. Perhaps a fee could be levied on the transaction - instead of rent seeking platform, a strong reputation system is incentivised.
If a reputation system was embedded in a blockchain based payment solution, a step change over what e-commerce, banking etc. provides would be achieved. I want to see if State Channels could help achieve it.
