TARA's total supply figures are updated on CoinMarketCap.
The initial supply is 10 billion tokens, but as outlined in our economics, block rewards from staking and running consensus nodes will be inflated, at a maximum of 20% annualized yield.
TARA's circulation is updated on CoinMarketCap.
You can find details about TARA's token allocation, unlock schedules at the Taraxa Token Information page.
TARA tokens are used for 3 things,
Gas fees: used to pay for transaction processing
Staking: used to secure the network against Sybil attacks, staking will have a maximum 20% total annualized yield, rewarded in the form of inflated tokens in block rewards.
Voting: used to vote on changes to the network.
The Taraxa network depends on proof of stake, therefore staking is a critical part of network security. We intend to roll out staking in several stages.
Pre-staking - consists of a simple contract and a web-based UI (part of the community site) that enables simple lock-in of TARA tokens on the ETH network, earning stakers period yields. This is to help us understand user behaviors and get the word out prior to mainnet release.
Mirrored staking - a Taraxa-ETH bridge will be set up whereby the stakes on ETH are read over to the staking contracts on the Taraxa testnet, this will help to test the actual staking contract without putting real assets at risk.
Mainnet staking - after mainnet is released, staking will simply take place on the mainnet via native tokens.

The Taraxa core development team looked very closely into Ethereum's EIP-1559, and found its goals of making transactions fees more predictable and less volatile a highly laudable goal. Without going into details, the fixed component of the fees is burned during the process while the variable is tipped to the miner.
Something similar is likely to be implemented in the Taraxa protocol as well, we'll keep the community updated on this.
You can read more about the Foundation's proposed governance model here in our whitepaper. After mainnet deployment, the core team will work hard to build in governance mechanisms directly into the code to prepare for truly decentralized and community-driven decision-making process.
