Background on T Emissions
Currently, Threshold Network uses token emissions to incentivize stakers to run nodes via the “Stable Yield” model. This incentive model targets a 15% annual yield for stakers who run both tBTC and TACo nodes.
Given historical staking rates since the launch of Threshold, this has resulted in an effective annual inflation rate of ~5% (or 500M T per year). At the current price of ~$0.025 per token, this is an annual emission cost of ~$12.5M.
tBTC Beta Staker Program
tBTC currently operates under the Beta Staker model (tBTC Stakers FAQ | Threshold Docs), where only a DAO approved subset of stakers are eligible to be selected for DKG ceremonies to become signers on custody wallets. Currently, there are 35 addresses approved as Beta Stakers, which are operated by 21 distinct legal and economic entities.
The DAO pays 18 of these operators between $2,000 and $3,000 per month to run nodes as part of the Beta Staker program, which is currently expected to sunset with the upgrade to Schnorr signatures in early 2025.
Extend the Beta Staker Program and Eliminate Inflation
The DAO could elect to extend the Beta Staker program through the Schnorr upgrade, maintain the permissioned operator set, and transition all 21 operators to paid, DAO-provided delegations (~$500,000 annual cost). This would enable eliminating T inflation rewards.
The fixed annual Beta Staker payments of ~$500,000 per year are less than the minting and redemption proceeds earned by the network, especially with the likely reinstating of the minting and redemption fees to 0.1% and 0.25%, respectively. Other major tBTC-related costs are bootstrap nodes ($360,000 annually) and optimistic minter and guardian role payments ($132,000 annually).
If this proposal is approved it’s likely that tBTC will achieve profitability at the protocol level (excluding other DAO-related costs). Surplus fees can optionally be directed to the T buyback program, potentially making T deflationary.
Path to Permissionless Signing
Signing will become fully permissionless with the introduction of BitVM2 vaults, rather than the Schnorr upgrade and there will be no incentive for non-Beta Staker nodes to stay up in the meantime.
Operational Details
Along with the cessation of staking rewards, this proposal would allow for immediate unstaking by non-Beta Stakers without the mandatory 45-day and 6-month cooldown periods for tBTC and TACo, respectively.
The Beta Staker nodes with delegations that are not from the DAO treasury will need to unstake and spin up new nodes with DAO delegations. Additionally, any operators running multiple Beta Staker nodes will unstake their duplicate nodes so that each independent operator is running a single Beta Staker node. The end result will be 21 beta staker nodes operated by 21 distinct legal and economic entities. The DAO can of course approve additional Beta Stakers at any time.
Deprecated Beta Staker nodes will need to be safely removed from any active tBTC wallets and TACo cohorts, via inter-wallet sweeping and the appropriate handover+refresh mechanism, respectively.
Finally, since the DAO will control all Beta Staker delegations it can reduce the amount of its staked T tokens to at or near the minimum stake for all the Beta Stakers, allowing the 90M T tokens it is currently delegating to be reallocated for alternative use.
