Fractal Bitcoin is creating a programmable layer secured by Bitcoin miners

In an interview with TheStreet Roundtable, Spencer Yang, co-founder of Fractal Bitcoin and managing partner of BlockSpaceForce, traced his journey from building CoinMarketCap and leading retail products at Coinbase to redefining Bitcoin’s potential.

After two and a half years ago, he saw a gap: while Bitcoin excels as a store of value, it can also power payments, applications and new protocols — if the right infrastructure is in place.

Standing out in a crowded field

At Bitcoin 2025, many scaling solutions vie for attention. Yang insists Fractal’s edge lies in respecting Bitcoin’s core. By merge-mining with major pools Fractal aligns miner incentives and reuses Bitcoin Core software.

“About 90% of Bitcoin hash rate from mining pools like Foundry, F2Pool, Antpool and ViaBTC are merge-mining Fractal and securing Fractal network on top of securing and receiving rewards for securing a Bitcoin network,” he said.

Developers building on Fractal tap directly into Bitcoin’s security — giving them a familiar, safe sandbox for innovation.

Putting Bitcoin to work

Yang outlined three guiding principles behind Fractal’s protocol design. First, miners securing Bitcoin today also receive Fractal block rewards, ensuring strong incentives.

Second, Fractal uses Bitcoin Script so any developer building on Fractal also contributes to Bitcoin’s security.

Third, the network makes it seamless to move assets between Bitcoin and Fractal — opening paths for productive use rather than passive holding.

Scaling Bitcoin

When asked to explain Fractal’s approach, Yang compared it to a skyscraper full of elevators. “Bitcoin is the first level. But if users want to do something that is maybe a little bit faster, then you go to the second level, and then you go to the third level,” he said.

“What I am very optimistic about in the next five years is more innovations, not just in the on-chain parts of the space, which we are very, very strong in,” Yang said. He urged developers to explore on-chain markets and contribute to the next wave of Bitcoin-powered products.
