OP_NET mentioned it’s launching a “SlowFi” decentralized finance (DeFi) stack on Bitcoin that makes use of customary Bitcoin transactions and native BTC charges reasonably than bridges, wrapped property or a separate fuel token.
In keeping with a Thursday launch shared with Cointelegraph, the venture is a part of a broader push to convey buying and selling and yield-style exercise instantly onto Bitcoin’s base layer as an alternative of routing it via sidechains, bridges or adjoining networks. OP_NET is betting some customers will settle for slower and costlier transactions in change for staying absolutely on Bitcoin.
In keeping with OP_NET co-founder Frederic Fosco, who goes by Danny Plainview, functions run via customary Bitcoin (BTC) transactions utilizing Taproot-based spends, whereas the platform’s NativeSwap mannequin is designed to assist token swaps with out wrapped BTC or a separate fuel asset. Plainview advised Cointelegraph that each transaction on OP_NET is “only a Bitcoin transaction with BTC as the one fuel asset.”
The launch lands in the midst of a rising struggle inside Bitcoin over whether or not DeFi-style and data-heavy makes use of of block area strengthen the community’s charge market or quantity to spam that crowds out financial transactions.
Plainview mentioned a swap would sometimes price about $1 to $2 beneath regular charge situations and roughly $10 to $20 when blocks are congested, as a result of customers pay solely customary Bitcoin community charges reasonably than a separate fuel token.
OP_NET describes the mannequin as “SlowFi,” arguing that Bitcoin’s roughly 10-minute block instances and congestion-driven exit friction could make liquidity stickier and produce longer-lived DeFi cycles than quicker chains.

Critics say OP_NET brings Ethereum-style DeFi bloat
Plainview framed layer-1 DeFi as a technique to assist miner income as block subsidies decline, arguing that “miners are bleeding” resulting from Bitcoin’s halving schedule. “The one factor that retains miners solvent is a charge market,” he mentioned, insisting that OP_NET doesn’t modify Bitcoin consensus.

That view has drawn criticism from Bitcoin customers who argue that pushing DeFi-style exercise onto layer 1 dilutes Bitcoin’s financial focus or clogs block area with nonessential transactions. In latest posts on X, some critics described OP_NET as an try and convey Ethereum-style crypto infrastructure onto Bitcoin.
Some maximalists argued that any try and develop Bitcoin’s use circumstances past cash made its proponents “sh*tcoiners” larping as Bitcoiners.

Plainview pushed again, saying that any fee-paying Taproot transaction ought to be handled as a professional use of block area.
He warned that drawing ethical strains round legitimate transactions handed de facto management of Bitcoin to whoever defines these classes. He mentioned:
“The entire level is that no person controls it.”
OP_NET retains DeFi on Bitcoin base layer
OP_NET enters a area already populated by earlier makes an attempt to convey programmability to Bitcoin, together with via RSK and Stacks.
RSK operates as a separate Ethereum Digital Machine-compatible sidechain with its personal RBTC fuel token and a federated BTC peg, that means customers transfer worth off mainnet and belief a federation to handle the bridge.
Stacks, against this, is a Bitcoin-anchored layer-2 with its personal STX token and sBTC mechanism, executing good contracts on a definite chain that settles periodically to Bitcoin reasonably than inside L1 transactions.
By protecting execution and charges instantly on Bitcoin and avoiding wrapped BTC or new fuel property, Plainview is betting that some customers will settle for slower, costlier transactions in change for staying totally on Bitcoin’s base layer.
