For example, if the current price of the cryptocurrency 301 is lower than the standard price, the cryptocurrency management server 300 increases the price of the cryptocurrency 301 by incinerating a portion of the cryptocurrency 301 in circulation, thereby increasing the price of the cryptocurrency 301 ( 301), the current price can be set as the determined standard price.

Meanwhile, the cryptocurrency management server 300 according to embodiments of the present invention can set the transaction speed of the blockchain network used to issue the cryptocurrency 301. The transaction speed of the blockchain network is a factor that determines the transmission speed of the cryptocurrency (301). The faster the transaction speed, the faster the transmission speed of the cryptocurrency (301). Conversely, the slower the transaction speed, the faster the transmission speed of the cryptocurrency (301). Transmission speed may slow down.

The cryptocurrency management server 300 may determine the transaction speed based on the current issuance volume of the cryptocurrency 301 and the transaction volume of the carbon credit 303 (i.e., the transaction volume of the exchange 305). Depending on the embodiment, the cryptocurrency management server 300 may set the transaction speed higher as the current issuance volume of the cryptocurrency 301 increases, and may set the transaction speed higher as the transaction volume of carbon credits 303 increases.

For example, the cryptocurrency management server 300 can set the transaction speed of the blockchain network according to Equation 1 below.

Here, TPS represents the transaction speed, TPS _ref represents the reference transaction speed, k is a pre-specified constant, N _total represents the target issuance amount of the pre-specified cryptocurrency 301, and N _cur is the target issuance amount of the cryptocurrency 301. It represents the current issuance volume, and TV represents the trading volume of carbon emissions rights (303).

The standard transaction speed is the speed at which a blockchain network processes transactions per unit time (e.g., 1 second) under certain conditions, and can be determined depending on the performance (hardware, algorithm) of the blockchain network. For example, the reference transaction speed may be the maximum transaction speed of the blockchain network.

The target issuance amount of cryptocurrency 301 represents the total number of cryptocurrency 301 to be issued by the blockchain network. For example, according to embodiments of the present invention, the target issuance amount of cryptocurrency 301 may be based on the target carbon reduction amount of the tree carbon absorption project.
