Cycle #76

We have received 2.66135200 BTC as rewards.

Dust transactions

There are many dust rewards of 200 sats from F2Pool bitcoin miner. We started to 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 40 transactions of 200 sats. This is something to keep in mind when doing accounting.

Rewards Part 1

Once we received 2.090745 BTC, we were converted 2 BTC to 56,519.917195 STX in two transactions:

• 2.07026495 BTC (+ 0.01914000 BTC fees) to proxy address: https://mempool.space/tx/2aa2f84199ecdda78f62e8131eae8199ba046a60d7d752c1e9d4ceab8a3cb680

• 2 BTC to STX via aBTC:
  a) BTC to swap pool: https://mempool.space/tx/1d924fe39ee1a107bcae9d3f0dcda73a3f916065a078be72e6eac62a5c34fa74
  b) swap pool to STX: https://explorer.hiro.so/txid/0x114f5afaee983666e61ec21535ec9b0272259cc4e50a1330f0a4c55b59ef1fc0?chain=mainnet

Then, the first part of rewards were distributed to all pool members but the city coin treasuries. Their share is hold in the proxy address until the end of the cycle for technical reasons required by the city coin contracts:

• 25,000.38 STX to pool address: https://explorer.hiro.so/txid/0x72fe9c25f9f57bbbb9a1165e1899164b25f1f1f6e2772daf7938c1d1ef6cc857?chain=mainnet

For the second part,  0.57176505 BTC were wrapped and swapped.

• 0.56673009 BTC (+ 0.00503496 fees) to proxy address: https://mempool.space/tx/98060c8efbe3b6b2ad5b37445b504e4bd2072bd55670d1945dc5cf6b83935781

• 0.51350649 BTC to 14,206.728524 STX via aBTC:
  a) BTC to swap pool: https://mempool.space/tx/c1b1f721a4fd4779196211703e88a02ae0c114fac7fcb67840b5373ed50d411f

Then, the second part of rewards were distributed to all standard pool members (6,284.042378 STX) and the total rewards were distributed to the city coin treasuries (39,442.224221 STX).

• 45,726.26 STX to pool address: https://explorer.hiro.so/txid/0x33e86acbcd6a4f563314df9396cb53af8f1210016590eb5764a1283923005a9f?chain=mainnet

Total Rewards

A total of 70,726.645124 STX were distributed to 1192 pool members and 2 contracts. The distribution was based on 46,151,581.189231 STX.

Preparing for Nakamoto Release (5% reserve)

This year, the Nakamoto hard fork will bring sBTC. This means that we will replace aBTC with sBTC. The flow will be similar: wrapping to sBTC, then exchanging to STX and distributing.

However, stackers need to do more work eventually, run stacks and a signer node. We are preparing for that and put around 5% of the rewards aside. We started to build up infrastructure and it will allow us to operate Stacks 3.0 signer nodes.

For cycle #76, we sent 0.131849752 BTC to the reserve. That is around 5% of the consolidated BTC UTXOs (2.090745 BTC + 0.57176505 BTC).

Wrapping using aBTC

The rewards were wrapped from BTC to STX via aBTC. This worked quite well and fast. It is transparent and minting aBTC happens automagically. You can read more about aBTC at https://docs.alexgo.io/bitcoin-bridge/abtc-a.k.a-alex-btc
