DeFi's new front: VerifiedX bets bitcoin's next chapter is programmable, private

With bitcoin BTC$78,378.96 cementing itself as institutional crypto’s reserve asset, a new wave of infrastructure projects is looking to answer a longstanding question: What exactly should people do with it?

VerifiedX, a decentralized layer-1 blockchain and Bitcoin sidechain project, said the key to the answer lies in making the largest cryptocurrency programmable while preserving the core ethos that made it valuable in the first place.

“Bitcoin needs to be left alone,” Jay Pollak, head of strategy and business development at the VerifiedX Foundation, told CoinDesk in an interview. “People need to build around it and build utility with it.”

VerifiedX positions itself between bitcoin maximalists — supporters who say BTC is the only digital asset anyone needs or holds any significant long-term value — and the sprawling decentralized finance (DeFi) ecosystem built around Ethereum and other blockchains.

Rather than converting bitcoin into representations like wrapped bitcoin (WBTC), in which custody of the original token passes to a third party, Pollak says the project enables “native” programmable bitcoin ownership through a self-custodial architecture using threshold signatures and taproot-based addresses.

The project refers to itself as both a sidechain and what Pollak calls a “reliever chain” — a term the company is trying to popularize to distinguish itself from existing scaling systems for the original blockchain.

“We’re not reinventing or changing Bitcoin,” he said. “You never leave the Bitcoin ecosystem.”

That distinction matters because Bitcoin DeFi is tiny even though bitcoin is crypto’s dominant asset. The total value locked in the ecosystem is just over $5 billion, according to DeFiLlama. Compare that with the more than $44 billion locked on Ethereum. Yet bitcoin accounts for some 60% of total cryptocurrency market capitalization, according to TradingView data.

For many bitcoin holders, particularly institutions, existing options have proven unappealing because they often rely on bridges, custodians or synthetic assets.

“Institutions don’t want synthetic DeFi,” Pollak said. “They want real, native DeFi.”

VerifiedX enters a crowded Bitcoin utility landscape. Projects like Rootstock, one of the oldest Bitcoin sidechains, have focused on bringing Ethereum-style smart contracts and DeFi applications to Bitcoin through merge-mining and a network compatible with the Ethereum Virtual Machine (EVM).
