Ocean Pool at 2% Hashrate: Is BIP-110 Signaling Fading Into Irrelevance? | Bitcoin Index

Ocean Mining is fighting a lonely battle.

The activist mining pool sits at #11 in global hashrate rankings with roughly 2% of Bitcoin’s mining power. That’s 24 blocks per week in a network where the top four pools control 71% of hashrate. Ocean’s claim to fame: it’s the only pool enabling miners to signal support for BIP-110, a controversial soft fork proposal designed to throttle ordinals and inscriptions by restricting arbitrary data storage in Bitcoin transactions.

As of March 10, 2026, exactly one mining operation has used that capability. Ocean’s founder, longtime Bitcoin Core developer Luke Dashjr, launched the pool in November 2023 with a vision of decentralized, ideologically-driven mining. Nearly two and a half years later, the numbers tell a different story: when mining profitability clashes with protocol purity, economics wins.

Ocean’s Vision: DATUM and “Pure Blocks”

Ocean built its identity around the DATUM protocol, an open-source framework that lets individual miners construct their own block templates using their own Bitcoin full nodes. This is a genuine technical innovation. At traditional pools like Foundry USA or AntPool, the pool operator decides which transactions go into blocks. Miners just point hashrate at a stratum endpoint and accept whatever the pool serves.

DATUM flips this model. Each miner runs a Bitcoin node, selects transactions according to their own rules, and receives block rewards directly via coinbase payouts instead of through pool-controlled wallets. No KYC. No custodial risk. No centralized transaction censorship.

This architecture enabled Ocean to mine what Dashjr calls “pure” blocks: templates that exclude ordinals, inscriptions, and other protocols Ocean considers spam. Using Bitcoin Knots (Dashjr’s stricter fork of Bitcoin Core), Ocean filters out transactions that embed arbitrary data in witness fields or exploit the witness discount to cheaply store images, text, and other non-monetary content on-chain.

Philosophically, this is compelling. Bitcoin’s block space should prioritize payments, not JPEGs. Ordinals and inscriptions burden every full node operator with permanent storage costs while paying discounted fees. And there’s a non-trivial risk that embedding arbitrary data could introduce illegal content into Bitcoin’s immutable ledger.

Economically, it’s a disaster. Ocean’s filtering means miners forfeit fee revenue from high-paying inscription transactions. Combined with small hashrate (which creates high payout variance) and the operational complexity of running DATUM, Ocean simply can’t compete with plug-and-play industrial pools.

The Numbers: Ocean at the Margins

As of March 2026, the top pools controlling Bitcoin’s hashrate are:

Foundry USA: 299 EH/s (30.1%)
AntPool: 211 EH/s (18.3%)
ViaBTC: 145 EH/s (13.0%)
F2Pool: 113 EH/s (10.0%)
SpiderPool: 98 EH/s (8.8%)

Down at #11: Ocean with roughly 14 EH/s (2.4%).

Ocean’s hashrate hasn’t budged meaningfully since launch. In April 2025, Tether announced it would deploy both existing and future Bitcoin mining operations to Ocean, citing alignment with DATUM’s decentralization ethos. That endorsement generated headlines but apparently little actual hashrate. Ocean remained below 3% throughout 2025 and into 2026.

Why? Because Ocean’s ideological differentiators impose real costs:

Higher payout variance: With 24 blocks per week, individual miners wait longer between payouts compared to Foundry’s ~300 blocks/week. For mining operations optimizing cashflow, this creates financing headaches.

Forfeited fee revenue: During periods of high inscription activity, excluding ordinals means leaving significant transaction fees on the table. Profit-maximizing miners won’t accept that tradeoff.

Operational complexity: Setting up DATUM requires running a full Bitcoin node and configuring block templates. Most industrial operators prefer pools where they simply point ASICs at an endpoint and get paid.

Institutional mining dominance: Bitcoin mining in 2026 is megawatt-scale operations run by public companies, hardware manufacturers, and institutional funds. These entities optimize for shareholder returns and uptime, not protocol philosophy.

Ocean serves a niche: small-to-mid-sized miners willing to trade profitability for ideological alignment. At 2%, that niche is small.

BIP-110: The Anti-Ordinals Soft Fork Nobody Wants

BIP-110 is Ocean’s political project. Formally titled “Reduced Data Temporary Softfork,” the proposal introduces seven consensus-level restrictions to limit arbitrary data storage:

ScriptPubKey size limit (34 bytes): New outputs capped at 34 bytes, except OP_RETURN (83 bytes max)
OP_PUSHDATA limit (256 bytes): Data pushes exceeding 256 bytes become invalid
Undefined witness versions prohibited: Spending from witness versions beyond v0/v1 Taproot becomes invalid
Taproot annex prohibited: Witness stacks containing a Taproot annex become invalid
Taproot control block limit (257 bytes): Caps Taptrees at 128 script leaves maximum
OP_SUCCESS opcodes invalid: Prevents using upgrade hooks for data storage
OP_IF/OP_NOTIF disabled in Tapscript: Closes a vector exploited by ordinals inscriptions

Critically, BIP-110 is temporary. It expires after approximately one year (52,416 blocks), with the proposal stating: “After a year, the soft fork expires, giving us time to come up with a more permanent solution.”

The activation mechanism is equally controversial. BIP-110 uses modified BIP9 with a 55% threshold (1,109 of 2,016 blocks per difficulty period) and mandatory activation at block 965,664 (roughly September 2026). This means the soft fork will activate regardless of signaling levels once September arrives. Nodes running BIP-110 software will begin rejecting blocks that don’t comply.

This is unprecedented. Historical Bitcoin soft forks used 90-95% thresholds:

SegWit (2017): 95% via BIP9
Taproot (2021): 90% via Speedy Trial

The rationale for high thresholds is minimizing chain split risk. If 10% of miners don’t upgrade, their minority chain dies quickly due to low hashrate and security. But if 45% don’t upgrade under BIP-110’s 55% threshold, you have two viable competing chains, a scenario that could wreck Bitcoin’s credibility and market value.

BIP-110 supporters argue the temporary nature reduces risk. Critics argue a year-long chain split would be catastrophic regardless of duration.

Signaling Status: Crickets

As of early March 2026, BIP-110 support is negligible:

Node support: 2.38% (583 of 24,481 reachable nodes)
Pool signaling: Zero pools, one individual miner
First signaling block: March 2, 2026 (Block 938,903, mined by Barefoot Mining)

The first BIP-110 signal came from Bob Burnett’s Barefoot Mining operation, an off-grid site powered by stranded natural gas. Burnett is also a board member at Ocean. Here’s the key point: Ocean as a pool did not signal. Burnett signaled individually using DATUM’s template construction feature.

This is a novel development in Bitcoin soft fork politics. Historically, signaling has been pool-level: during SegWit (2017) and Taproot (2021), everyone watched announcements from major pools. Individual miners had no voice because pools controlled block templates.

DATUM changes that. Any miner on Ocean can independently signal for or against a soft fork by constructing their own templates. But there’s a critical limitation: Ocean is not enforcing BIP-110 rules. Miners can signal, but they can’t enforce. If BIP-110 activates, full enforcement would require Ocean to upgrade its pool software or miners to leave.

So far, only Burnett has bothered to signal. And no other pool has joined.

Why Major Pools Are Sitting This Out

Foundry USA (30% hashrate): No statement.
AntPool (18%): No statement.
ViaBTC (13%): No statement.
F2Pool (10%): Co-founder Chun Wang stated on February 19, 2026: “No way we’ll signal BIP-110.”

The pattern is clear: large pools avoid protocol controversy. They serve miners who want predictable returns, not ideological battles. Signaling for BIP-110 would:

Alienate miners who support ordinals/inscriptions
Create PR risk if the fork causes a chain split
Offer no economic benefit (BIP-110 doesn’t change block rewards or fees)

Pools optimize for operational scale, institutional relationships, and miner satisfaction. Ocean’s activism doesn’t fit that model.

The Economic Node Problem

Bitcoin developer Jameson Lopp wrote in late February 2026:

“Although there are many nodes signaling support, as far as I can tell these nodes have no economic power. A soft fork that is designed to reject blocks from miners ONLY works if the nodes rejecting the blocks are nodes that the miner NEEDS to accept in order to ‘cash out’ their coinbase rewards. To date, no BIP-110 proponents are willing to put their money where their mouths are.”

This is the critical question for any User-Activated Soft Fork (UASF): Do exchanges, payment processors, and major economic actors support it?

During SegWit’s 2017 UASF campaign (BIP148), major exchanges and infrastructure providers signaled support. When miners realized economic nodes would reject their blocks, they capitulated and activated SegWit just before the August 1 deadline.

BIP-110 has no such support. The 583 nodes signaling represent hobbyists and activists, not economic weight. No exchange has announced they’ll run BIP-110 software. No payment processors have committed. Without economic nodes enforcing the rules, miners can safely ignore BIP-110 even if it technically “activates” in September.

The likely outcome: BIP-110 nodes fork onto a minority chain with negligible hashrate and zero economic value. The main chain continues as before, ordinals and all.

What Ocean’s Struggle Reveals

Ocean’s 2% hashrate and BIP-110’s flatlining support tell a clear story: protocol activism through mining alone cannot succeed against economic incentives.

Ocean offers genuine technical innovation (DATUM), philosophical coherence (Bitcoin as money, not data storage), and operational transparency (non-custodial, no KYC). These are real advantages. But they don’t move hashrate when competing against pools that:

Maximize fee revenue by including all high-paying transactions
Minimize payout variance through massive hashrate scale
Offer plug-and-play simplicity instead of full-node complexity
Stay neutral on controversial protocol debates

The Tether partnership announcement generated headlines but no meaningful growth. Industrial miners optimize for profitability, not purity.

This dynamic has broader implications for Bitcoin governance. Soft forks used to be miner-driven: pools coordinated upgrades, and the network followed. SegWit flipped that model by showing economic nodes can force miner compliance when exchanges and infrastructure providers coordinate.

But BIP-110 has neither miner support nor economic node backing. It’s a grassroots campaign championed by one small pool and a handful of developers. In Bitcoin’s current industrial landscape, that’s not enough.

September 2026 will arrive. BIP-110’s mandatory activation will trigger on nodes running its software. And unless something dramatic changes, the main chain will ignore it. Ocean will remain at 2%. Ordinals will persist. And the debate about Bitcoin’s purpose will continue unresolved.

Ocean’s activism matters. It demonstrates technical alternatives, asks important questions about Bitcoin’s role as money versus data storage, and provides options for miners who share its values. But at 2%, Ocean isn’t driving consensus. It’s a voice in the wilderness, not a force shaping Bitcoin’s future.

In Bitcoin’s industrial era, protocol change requires developer consensus, economic node support, and broad coordination. A small pool with strong ideology can’t overcome those barriers alone.
