# 8.1 Token Introduction

Token Name: CCC (Credit Check Coin)

**Uses：**

1. Similar to ETH, programs and transactions running on the 3C ecosystem require to pay transaction fees, also known as Gas Fee, to 3C. This fee covers the costs of nodes operation, computation, and credit privacy verification.
2. CCC can be used as a reward for the nodes operating on the 3C network, either for running on-chain applications or verifying outputs. CCC can also be used for voting in the governance of the 3C network ecosystem. Additionally, CCC can be staked to become a blockchain node and can be used to pay for gas fee on the 3C network.

**Inflation Rate Design：**

1. Initial Inflation Rate: 8%
2. Inflation Rate: −15%
3. Long-term Inflation Rate: 1.5%

**Transaction Fee:**

1. iA fixed portion (initially 50%) of each transaction fee is destroyed, and the remaining fee is given to the current leader responsible for processing the transaction.
2. The transaction fee is adjustable and determined by the network cluster based on recent historical throughput. The minimum portion of each transaction fee can be dynamically adjusted based on the historical signature utilization in each slot. This allows the protocol to target the desired hardware utilization using the minimum fee. By monitoring the protocol-specified signatures per desired utilization in each slot, the minimum fee can be increased/decreased, which should in turn decrease/increase the actual signatures per slot per block until the target utilization is achieved.
