- The block value differs between currencies and overtime.
- Currently a bitcoin block value is 12.5 BTC + accumulated bitcoin network transaction fees.
- Each minable currency has a unique block value, which changes overtime according to their unique algorithms. Click here for Multipool's supported cryptocurrency coin statistics.
- Accumulated network transaction fees are not applicable to all currencies and varies block to block per its network variables.
- NOTE: Multipool.us is currently operating BTC ONLY as a https://slushpool.com subpool, which uses an exponential. scoring system
- Once the Slushpool reward is received it is distributed to https://Multipool.us miners proportionality.
- NOTE: Currently only BCH and LTC operate using the PPLNS payout method.
- The pool fee is 1.5% of each block received across all currencies.
- Optional donations are adjusted in the user account settings.
- The pool hashrate contribution is the sum of the total users hashrate contributions relative to a specific currency at the time the block is found, ending the current round.
- Your hashrate contribution (aka shares or cumulative accepted difficulty) is your cumulative accepted hashes from weighted share difficulties.
- Assigned difficulty - The pool determines the difficulty for each miner by reassessing the number of verified hashes completed submitted every few seconds targeting one cumulative accepted share every 5-10 seconds.
- Verified hash completed - While the miner is seeking to be the first "miner" to find a nonce that delivers a desirable hash is reward the current block, the amount of computing power is determined using a Proof of Work scheme by sending computational puzzles to the miners known as a CPU cost function.
- Unverified hashes - Hardware errors, stale shares, duplicate shares are some reasons why a hash share could be rejected or considered bad.
- For example your cumulative accepted difficulty is 1000 if your share difficulty is 100 and submit 10 shares.
- Proportional ("Share-based") - For each block found, the reward is split between miners according to the number of cumulative shares they submitted.
PPLNS (Pay per last N shares) - Payouts are connected to blocks found, but calculated by looking at the proportion of miners contributed shares to the pools shares based on the last N difficulty round (which is different than the block to block round).
- BCH: PPLNS round is equivalent to 720 network blocks (approx. 5 days)
- LTC: PPLNS round is equivalent to 2304 network blocks (approx. 4 days)
- PPS (Pay per share) - Every share submitted receives a fixed reward set in advance. Pool Operators often take a larger fee, as the true value of each share its unknown until the block is found.
