84% of Bitcoin Hashrate Secured Rootstock in Q1

Rootstock’s Q1 2026 merged-mining report states that 84.01% of Bitcoin’s total hashrate, roughly 833.92 EH/s, contributed to securing the Rootstock sidechain during the quarter. The report’s hashrate figures use seven-day averages from blockchain data and are extrapolated from the share of Bitcoin blocks that were also used to mine Rootstock blocks, making the metric a measure of security participation rather than direct economic flows.

Rootstock implements merged mining, which allows Bitcoin mining pools to submit work to Rootstock while continuing to mine Bitcoin. The report records that 93.10% of observed mining-pool hashrate participated in merged mining in Q1 2026.

The distribution of contributed hashpower was concentrated among a small group of large pools. Foundry USA accounted for 36.62% of Rootstock’s reported distribution, AntPool 19.92%, F2Pool 12.79%, ViaBTC 11.79% and SecPool 4.98%, according to the report.

The Q1 report notes that network fees are paid to miners in Bitcoin but does not provide a breakdown of miner revenue from Rootstock fees. Market measures for Rootstock ecosystem tokens were modest in Q1 2026: the rBTC-pegged asset had a market value of about $19.9 million and the Rootstock Infrastructure Framework token about $74.4 million.

Industry reports placed hashprice near $29 per PH/day in Q1 2026 and estimated that roughly 15%–20% of the global mining fleet was unprofitable at about $30 per PH/day. A market index showed hashprice at $35.78 per PH/day and the Bitcoin network hashrate near 984.34 EH/s. At the time, Bitcoin traded near $77,300 with a market capitalization around $1.55 trillion and the block subsidy was 3.125 BTC.

An earlier industry report covering Q1 2025 recorded merged-mining participation averaging about 81% while reporting declines in active addresses and decentralized finance total value locked. Rootstock’s Q1 2026 merged-mining report does not include user metrics such as transaction volume, active users or fee revenue per miner.

The Q1 2026 report presents the hashrate participation metric, the pool-distribution table and the underlying methodology for calculating Rootstock hashrate.
