## What is OCEAN

OCEAN is a non-custodial Bitcoin mining pool run by Bitcoin Ocean, LLC, a Wyoming company and subsidiary of Mummolin, Inc. Miners connect with only a Bitcoin address and are paid directly in the block's coinbase transaction under its TIDES reward system. Since 2024 miners can also build their own block templates with the DATUM protocol.

## Coins, payout schemes and fees

| Coin | Payout scheme | Pool fee | Minimum payout |
|---|---|---|---|
| BTC | TIDES | 2% (1% when building own templates with DATUM) (as of 31 October 2026) | 0.01048576 BTC (1,048,576 sats) on-chain; lower via Lightning |

## Payouts

| Parameter | Details |
|---|---|
| Pool fee | 2% of the block reward and transaction fees of each block found; 1% for miners who make their own blocks using DATUM. |
| Payout scheme explained | TIDES (Transparent Index of Distinct Extended Shares) splits each block reward over the most recent shares, so each share is paid on average about 8 times; miners can verify their share. |
| Payout schedule | Paid when the pool finds a block, directly in the coinbase (generation) transaction; coins are spendable after 100 blocks. |
| Lightning payouts | Optional Lightning payouts with BOLT12 offers allow payouts below the on-chain threshold. |
| Small balances | If a miner stops or changes address, the pool will try to pay balances from 0.00065536 BTC at its discretion. |

## Connecting

| Parameter | Details |
|---|---|
| Server regions | Single endpoint mine.ocean.xyz:3334; server locations are not listed. |
| Account needed | No account: the username is a Bitcoin address (optionally address.workername), password "x". |
| Protocol | Stratum; DATUM lets miners build their own block templates instead of using the pool's. |
| Supported hardware | Bitcoin ASIC miners; addresses of type P2PKH, P2SH, Bech32 and Bech32m are accepted. |

## Security and transparency

- Non-custodial: rewards are paid by the Bitcoin network in the coinbase transaction rather than held by the pool.
- TIDES payouts are designed to be auditable, so any dishonesty by the pool would be provable.
- OCEAN reports SOC 1 and SOC 2 Type 2 attestations.
