Binance Opened Its Bitcoin Mining Pool

Binance officially opened Binance Pool on April 27, 2020, moving the cryptocurrency exchange into the infrastructure that organized Bitcoin hash power and distributed mining revenue.

The first product pooled computing power for Bitcoin mining and used a Full Pay-Per-Share, or FPPS, payout method. Binance also presented the platform as capable of supporting proof-of-work and proof-of-stake assets, although Bitcoin mining was the service available at launch. A contemporaneous report from The Block independently confirmed the April 27 opening and the initial Bitcoin focus.

The development mattered because Binance was no longer serving miners only as a place to sell newly produced bitcoin. It was becoming the operator responsible for accepting their contributed work, calculating their shares and paying their mining income. Binance designed those proceeds to arrive inside customer exchange accounts, where they could be traded or used through other services on the platform.

Pooling revenue before the halving

Bitcoin miners compete to produce valid blocks, but an individual miner’s short-term results can vary sharply even when its machines operate continuously. A mining pool combines the work of many participants and distributes revenue according to the computing work each participant submits.

Under an FPPS arrangement, the operator pays participants for valid shares using an estimated value for both the block subsidy and transaction fees. This smooths the irregular timing of block discoveries for miners, while leaving the pool operator responsible for differences between expected and realized block revenue.

Bitcoin’s block subsidy was 12.5 BTC on April 27. The protocol’s next scheduled subsidy reduction was approaching, creating pressure on miners to evaluate equipment efficiency, electricity expense, pool charges and payout reliability. Binance promoted a zero-fee introductory period ending June 1, 2020 at 08:00 Hong Kong time, equivalent to 00:00 UTC. That was a stated service fee promotion, not a forecast of mining profitability.

Neither the FPPS structure nor the introductory fee eliminated operating risk. A miner’s results still depended on contributed hash rate, network difficulty, equipment availability, electricity costs, transaction-fee conditions and the pool operator’s accounting and payment performance.

An exchange reaches further into Bitcoin infrastructure

Binance was following other exchanges into mining rather than creating the exchange-operated pool model. CoinDesk reported on April 1, 2020 that OKEx and Huobi had introduced pools during 2019 and that both had reached the ten largest pools by blocks produced at that observation point.

That precedent explained the strategic attraction. Mining generated a recurring flow of bitcoin, while an exchange could give miners an integrated place to receive, trade, borrow against or otherwise deploy those proceeds. Binance’s launch materials explicitly promoted this connection between mining and its broader financial-services platform.

The integration also concentrated several functions under one commercial operator. Binance could maintain the customer account, operate the pool, calculate rewards and provide the market where those rewards might be sold. This reduced operational steps for participating miners but increased their dependence on the exchange’s systems, terms and custody arrangements.

What the launch established

A pool’s reported hash rate is not equivalent to permanent ownership of mining equipment or irrevocable control over miners. Participants can generally redirect compatible machines to another pool. Nevertheless, pool operators coordinate block construction and payouts while miners remain connected, making the distribution of hash power among operators relevant to Bitcoin’s resilience.

Binance argued that adding another competitor would make the mining field more decentralized. That was a contemporaneous company claim, not a result demonstrated by the launch itself. The April 27 records do not establish Binance Pool’s durable share of Bitcoin hash rate, the number or geographic distribution of participating miners, or whether its entry reduced concentration over time.

What the evidence does establish is narrower: on April 27, Binance opened a Bitcoin FPPS pool and connected mining income directly to its exchange ecosystem. The launch marked another step in the convergence of cryptocurrency trading, custody, lending and block-production services under large platform operators.
