Bitlayer has secured 31.5% of Bitcoin’s total hashrate through strategic partnerships with major mining pools, marking a pivotal step in bringing Turing-complete smart contracts to the Bitcoin network. This development comes as Bitcoin mining firms like Bitdeer accelerate hardware deployments while others including Bitfarms shift focus to high-performance computing infrastructure.
The BitVM-powered solution enables complex computational verification through an optimistic rollup-like system, processing transactions off-chain while using Bitcoin’s base layer as final settlement. This approach avoids protocol-level changes while introducing Ethereum-style programmability through Layer 2 implementation.

Bitlayer’s Technical Breakthrough
At the core of Bitlayer’s architecture lies BitVM – a revolutionary paradigm enabling Bitcoin contracts through optimistic validation. The system uses pre-signed transactions and challenge-response mechanisms to verify off-chain computations, with Bitcoin script enforcing honest behavior through financial penalties.
The platform recently partnered with BitZap DEX to create a decentralized trading hub for Bitcoin-native assets. This integration enables trustless swaps of BRC-20 tokens and Layer 2 assets while maintaining Bitcoin’s security guarantees.
Bitdeer’s Mining Hardware Expansion
Bitdeer reported a 45.6% monthly increase in self-mined Bitcoin during April 2025, producing 166 BTC through its proprietary SEALMINER hardware. The company has committed $240 million to TSMC for advanced 3nm chip production, aiming to reach 40 EH/s of mining capacity by year-end.
| Metric | Bitdeer | Bitfarms |
|---|---|---|
| April 2025 Production | 166 BTC | 268 BTC |
| Hashrate Target | 40 EH/s | 19.5 EH/s |
| Hardware Investment | $240M | $0 (2025-26) |
The mining firm’s SEALMINER A1 units now account for 12 EH/s of operational capacity, with 28 EH/s of next-gen A2 models scheduled for deployment in Q3 2025. This expansion aligns with Bitlayer’s need for robust hashrate to secure its smart contract network.
Industry Shift to Compute Diversification
While Bitdeer expands mining operations, Bitfarms has joined peers in halting new miner purchases through 2026. The company will focus on developing HPC infrastructure at its Panther Creek facility using a $300 million Macquarie Group loan facility.
This strategic pivot reflects growing interest in AI workload capabilities among mining firms. Bitfarms CEO Ben Gagnon noted the company sold 150% of its April Bitcoin production to fund infrastructure development, prioritizing long-term compute flexibility over immediate hashrate growth.

The convergence of Bitcoin mining and smart contract development signals a new phase in blockchain infrastructure. As Bitlayer demonstrates Bitcoin’s programmability potential through its hashrate-backed network, mining firms face strategic decisions between specializing in pure hashrate operations or diversifying into broader compute markets – choices that could reshape the cryptocurrency ecosystem’s fundamental economics.
