Mark Artymko is President of OCEAN, a non-custodial Bitcoin mining pool operated by Bitcoin Ocean, LLC, a subsidiary of Mummolin, Inc. He spent approximately two decades in high-voltage power-system design and utility operations in Canada and the United States before moving into Bitcoin full-time. OCEAN seeks to reduce mining-pool intermediation through direct network payouts and miner-created block templates using DATUM.
OCEAN Mining Pool
OCEAN is a mining pool, not a cloud-mining investment product. Its non-custodial payout model pays miners directly from the Bitcoin network, subject to thresholds and pool rules. DATUM lets participating miners build block templates, reducing pool-operator control over transaction selection. Non-custodial does not remove pool variance, software, network or operational risk. Do not imply OCEAN controls Bitcoin governance.
Career Background
Approximately 18–20 years in high-voltage power-system design, construction and operations. Specialized in integrating large electrical loads onto utility grids. Entered Bitcoin deeply around 2021, according to OCEAN's team biography. Joined OCEAN/Mummolin leadership and became President. Co-founder status requires corporate confirmation before being added.
