Foundry USA Dominance
Daily share of network hash power produced by Foundry USA pool, expressed as a percentage of total blocks mined.
What is it?
Daily percentage of blocks mined by the Foundry USA pool, expressed as a share of total network hash power. Foundry USA became a major actor post-2021 after the China mining ban, attracting relocated hash power to North America. Its rapid growth made it one of the largest pools globally within a few years.
How to read
A stable share around a high level reflects an established leader position. A rapid rise indicates miner migration to this pool - often in reaction to a disruption at a competitor or a competitive fee offering. A sustained drop may indicate loss of confidence, migration to other pools, or a geographic rotation of hash power.
Key zones
A share around 25-30% positions Foundry as a structurally dominant market actor. Above 35%, concentration becomes concerning from a security standpoint (transaction censorship risk, selfish-mining attacks). A share below 15% would indicate increasing market dispersion, an unlikely scenario in the short term given economies of scale.
What to observe
Compare the trajectory with those of Antpool and F2Pool to identify hash power rotations. Watch US regulatory announcements (Texas, New York) which can directly affect Foundry's viability. Geopolitical stress episodes in China or elsewhere have historically benefited Foundry as a North American refuge.
Historical context
Foundry USA was born as a subsidiary of Digital Currency Group (DCG). Its spectacular rise post-2021 coincided with the China mining ban and the massive relocation of hash power to North America. Within a few years, it went from a marginal actor to the world's number one pool status on certain periods.
Expert notes
Foundry USA operates a full-pay-per-share (FPPS) model that ensures predictable revenue for miners, partly behind its attractiveness. Its corporate structure as a subsidiary of a listed group indirectly subjects it to US regulatory constraints (potential KYC/AML on partner operators) which may affect its hash power composition over time.
Common mistakes to avoid
A high Foundry dominance does not indicate that hash power is physically in the United States - miners connect from any jurisdiction. The pool's HQ country does not determine the effective hashrate location. For a real geographic reading, cross-reference with independent estimates based on latency or local regulation.
