There was an initial iteration of the network name Kusangi which was started on the 3rd January 2021 and then halted in the middle of May so that some issues could be addressed. The blockchain and all 546,113 previously mined TAO were migrated to Nakamoto which was started on 2nd November 2021 from block 0. The Finney network network was officially launched on the 20th March 2023.
The total token issuance rather than the block number is used to determine the exact point the halvening occurs. As Tao used to recycle registrations is burned back into the unissued supply, there is a lengthening halvening data however this data is calculated at the current block/issuance so will update automatically over time.
The total issuance used in Taostats is taken directly from the substrate blockchain.
The total supply of 21 million is pre-programmed. A block is mined about every 12 seconds, rewarding the miners and validators with 1 TAO per block. At the current inflation schedule this leads to 7200 new TAO being issued into circulation every 24 hours which is currently split evenly between miners and validators.
Once half of the supply has been issued the rate of issuance is halved — with 12 seconds per block that amounts to a halving every 4 years. Every half marker of the remaining amount to be issued creates a new halvening event until all 21 million TAO are in circulation.
