An account is an entity that is identified by a unique address, which can send transactions on the blockchain.
The account structure is 16 bytes long and consists the following fields:
The Treasury account is a special account that is defined at the genesis time. The Treasury account holds the total supply of Pactus coins, which is fixed at 21 million coins, and each coin is divided into 1 billion units.
The sequence number of the Treasury account is the same as the number of blocks in the blockchain. In each block, one coin from the treasury account is transferred to the proposer account as block reward.
This block reward serves as an incentive for validators to propose and validate new blocks on the blockchain. As a result, the total number of Pactus coins in circulation increases gradually over time as new blocks are added to the blockchain.
