Cycle #85

We received 4.02195000 BTC as rewards.

Payout in STX and BTC

We introduced a new distribution flow in BTC on individual requests. The BTC rewards were split proportionally.

For cycle 85, we used

Liquid Stacking With LISA

This cycle, the Liquid Stacking service LISA with FAST Pool as part of Lisa’s backend delegated 4,005,986.256201 STX to Fast Pool. Lisa used 4 smart contract as pool members (similar to city coin pool members). The share of Lisa was 12.320773% of the pool.

The rewards were distributed with the normal distribution flow:

Dust transactions

There are many dust rewards of 200 sats and 550 sats. We ignore these utxos because consolidating them is more expensive then their value. That means that a few sats will rest in the pox reward address. For this cycle, there were 76,400 sats left in the wallet after reward distribution. This is something to keep in mind when doing accounting.

Consolidation and Swapping

After 1 week, we consolidated all rewards and swapped 2.78998365 BTC to 96,986.2032 STX

The following swaps were executed via

Balance between STX and BTC rewards

We converted more BTC to STX than needed for the 436 stackers who want to receive rewards in STX. Therefore, we converted a portion back using the Fast Pool treasury (at the costs of Fast Pool treasury):

For 2.60436290 BTC, we receive 90,533.6020 STX rewards (969862032 uSTX × 260436290 sats ÷ 278998365 sats). The difference was 4508.9442 STX = 0.12970794 BTC. This amount was swapped:

Total Rewards

A total of 86,006.9219 STX were distributed to 432 pool members and 4 contracts. The distribution was based on 21,054,082.866271 STX stacked to receive STX rewards.

A total of 1.34661491 BTC were distributed to 1 pool member from the proxy btc address. The distribution was based on 11,459,999 STX stacked to receive BTC rewards.

If all BTC rewards were distributed as STX rewards the total would have been 132,821.558530 STX based on 32,514,081.866271 STX stacked.

Preparing for Nakamoto Release (5% reserve)

This year, the Nakamoto hard fork will bring sBTC. This means that we will wrap BTC to sBTC, then exchange to STX and distribute.

However, stackers need to do more work eventually, run stacks and a signer node. We successfully started to be signer for Stacks 2.5 and are registered since cycle #84 as signer.

For cycle #84, we 4,526.6801 STX from STX distribution and 1,942 STX from BTC distribution to the reserve. That is a around than 4.87% of the theoretical total STX rewards.

Swapping using simpleswap

Swapping using simpleswap is not as transparent as using aBTC via Xlink bridge. Therefore, here is a screenshot with the exchange ids:
