Claim 6:
7. A method for calculating payment, contribution, investment and dividend return of carbon emission charges/contributions based on a blockchain, performed by a platform system including a financial institution server, a carbon pay server, a customer terminal, a customer node device, a non-profit contribution options node device, and a profitable investment options node device, the method comprising:
requesting, by the carbon pay server, data inquiry comprising user's transaction details data to the financial institution server through a network including an Internet network or a mobile communication network;
crawling and transmitting, by the financial institution server, the user's transaction details data;
receiving, by the carbon pay server, the user's transaction details data;
calculating, by the carbon pay server, through an algorithm stored in the carbon pay server, a result value comprising carbon emissions, a consumption pattern, and voluntary carbon emission charges/contributions based on the crawled user's transaction details data;
transmitting, by the carbon pay server, the result value for the carbon emissions, the charges/contributions, and the consumption pattern calculated in the carbon pay server to the customer terminal through the network;
when a user pays the charges/contributions to a financial product according to the result value, managing, by the customer terminal, the paid charges/contributions in a form of a portfolio of investment and displaying, on the customer terminal, data of the principal investment and dividend return from the invested climate related financial product;
sharing, by the customer node device, the non-profit contribution options node device, and the profitable investment options node device, which are connected through a blockchain network, transaction information of investments and earnings;
performing, by the customer node device, the non-profit contribution options node device, and the profitable investment options node device, functions including a wallet function of generating and confirming a transaction with an identified address, a function of decrypting by using a computer to obtain right to create a block, and a mining function of receiving coins in return; and
verifying and approving, by the customer node device, the non-profit contribution options node device, and the profitable investment options node device, transactions and blocks, and performing P2P network transmission.
