The ongoing debate between different mining protocols often misses the fundamental point about Bitcoin mining decentralization. While technical communities argue over Stratum v2 versus alternatives like Datum, the real challenge lies not in the tools themselves, but in mining participants' willingness to prioritize decentralization over convenience and immediate profitability.

Consider the BitTorrent analogy: when it revolutionized file sharing by introducing decentralized peer-to-peer networks instead of centralized servers, the breakthrough wasn't in the underlying protocols, but in the fundamental shift toward decentralization. Similarly, in Bitcoin mining, protocol choice becomes secondary to the commitment to actually implement decentralized solutions.

The current state reveals a stark contradiction between Bitcoin's decentralized ideals and operational reality. Since early 2024, approximately 90 Bitcoin addresses have captured everything coming out of the blockchain, with roughly 90% of all block rewards flowing to just five major pools. Many apparently independent smaller pools are actually operated by the same entities, particularly Bitmain, sharing custodial services behind the scenes.

This centralization extends beyond reward distribution to block construction fundamentals. For years, miners have accepted complete pool control over transaction selection and block template creation, while simply providing computational power without insight into what they're actually mining. The traditional mantras "not your keys, not your coins" and "don't trust, verify" have been conspicuously absent from mining, where participants mine on pool-created templates and receive payments from separate funding sources rather than directly from blockchain rewards.

Ocean Mining seeks to restore transparency and sovereignty by letting miners directly influence block contents while still benefiting from pooled rewards. Unlike traditional pools that reveal blocks only after discovery, Ocean shows templates before mining begins, allowing participants to decide whether they support transaction policies. This visibility has led some miners to leave pools over disagreements, while others join precisely for the transparent approach.

The pool offers multiple block template options, demonstrating real miner choice. These include Bitcoin Core’s default, an “all disrespected” version that accepts certain privacy transactions, and a data-free template excluding arbitrary data. Miners have successfully found blocks with each option, proving that conscious decisions about block content are possible in practice.

The next step is the Datum protocol, which empowers miners to run their own nodes, source transactions directly, and construct independent templates. When using Datum, miners retain complete sovereignty over block creation while still sharing rewards from pooled work, combining autonomy with economic stability.

The Full Pay Per Share (FPPS) payout model represents one of the most significant threats to Bitcoin mining decentralization, despite its popularity among miners seeking consistent income. FPPS promises regular payments based on hashrate regardless of whether pools actually find blocks, essentially functioning as insurance that smooths out Bitcoin's natural mining variance.

The fundamental FPPS problem becomes apparent when considering Bitcoin's evolution from predictable block subsidies to increasingly variable transaction fees. Early Bitcoin's 50-coin block reward with minimal fees created predictable income calculable from network difficulty and individual hashrate. However, as block subsidies have halved repeatedly and transaction fees have become significant revenue portions, the predictability that made FPPS feasible has disappeared.

Modern Bitcoin blocks vary dramatically in total rewards depending on network congestion, fee market dynamics, and periodic spam attacks or new token launches. This variability makes it impossible for any entity to accurately predict short-term mining income, yet FPPS providers must guarantee payments regardless of actual blockchain outcomes. The only way to offer such guarantees sustainably is taking substantial margins from miners, effectively charging them for avoiding natural Bitcoin variance.

Ocean's comparative analysis demonstrates FPPS's hidden costs. Even during significant bad luck periods, including finding three empty blocks and experiencing extended periods without discoveries, Ocean miners earned more than 10% above FPPS pool counterparts, suggesting FPPS insurance's true cost far exceeds nominal advertised fees.

Ocean is designing a share marketplace that gives miners FPPS-like stability without centralization. Instead of relying on insurance-like pools, miners can sell their shares to buyers who pay upfront for the right to receive future block rewards when those shares win. This model balances miners’ need for consistent income with Bitcoin’s decentralization goals.

Through this marketplace, miners gain immediate cash flow by selling shares as they are generated. Buyers, meanwhile, obtain newly mined Bitcoin with clear on-chain provenance—valuable for regulatory purposes. Lightning Network users can also benefit, purchasing shares to solve liquidity issues by converting outbound capacity into eventual on-chain Bitcoin.

Ocean coordinates the marketplace but never acts as counterparty. Prices are set by supply and demand, unlike FPPS pools that absorb all risk and add margins. Buyers and sellers negotiate based on risk tolerance and liquidity needs, enabling more efficient pricing than fixed-rate models.

The approach also streamlines Bitcoin’s on-chain footprint. Instead of many small payouts to miners, shares can be aggregated into fewer outputs, saving block space while preserving economic benefits for smaller participants. The broader goal is reducing centralized pool power: when miners control templates and maintain direct blockchain interaction, even extreme centralization poses minimal risk to network sovereignty.
