# Total Supply and Issuance * **Total Supply:**\ The total supply of XSAT is capped at 21,000,000 tokens, mirroring the supply of Bitcoin. * **Issuance and Halving:**\ The issuance of XSAT rewards follows a structure similar to Bitcoin's halving rules. The exSat network begins synchronizing Bitcoin blocks starting from block height 840,000, which is also when XSAT rewards start to be distributed. Rewards are issued after each Bitcoin block is processed and becomes irreversible. Initially, the reward per block is 50 XSAT. Every 210,000 Bitcoin blocks (approximately every 4 years), the block reward is halved. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
