10. STX is required to bid on blocks

Winner Selection

After miners send their STX to the contract, a winner is selected by a Verifiable Random Function (VRF) weighted by the individual miners' bid compared to the total miners' bids sent in that block.

e.g. if Alice sends 10 STX into the contract and Bob sends 30 STX, then Alice has a 25% chance and Bob has a 75% chance to win in that block.

Mining rewards cannot be claimed until a 100 block maturity window passes, see the Claiming Mining Rewards for more info.

As soon as mining starts, block mining bids will appear here:

3. Mining Probabilistic Distribution

Run various scenarios:

Bid 10 STX for 100 blocks, what’s the probability of wining?

Bid 20 STX for 150 blocks, what’s the probability…?

More info on a mining strategy: See chart below from CityCoins Docs,

An example with real numbers: the table below assumes the total committed by miners is 500 STX, and you have 200 STX to spend.

2. Join a public mining pool?

In order to compete with other miner bids per block, joining a public mining pool may increase the probability of winning.

There is a public pool run by the Syvita Guild, a boutique development organization supporting the Stacks ecosystem.

As of today, more than 535,000 STX have been sent to the mining pool wallet.

Mining pool requirements: more than 150 STX is required to participate and 4% mgmt fee. Deadline is Friday, November 12 at 11:59pm CST. All the standards risks apply such as loss of funds. Any mining rewards would only be sent out 100 blocks before the cycle 1 stacking starts, which is in about 2 weeks:

1. Most importantly, once STX are submitted to the contract, they are not returned, they are distributed to the city's custodied wallet and Stackers of a CityCoin.
