Adam Back says bitcoin is beating DeFi

Blockstream CEO Adam Back told Consensus Miami 2026 that bitcoin is winning a security war against DeFi, and that pension funds and sovereign entities are the next buyers.

Blockstream CEO Adam Back argued at Consensus Miami 2026 that Bitcoin’s comparatively simple network architecture is separating it from more experimental blockchain ecosystems that have suffered repeated smart contract failures.

Back described the dynamic as Bitcoin winning “the DeFi security war,” as institutional investors grow more sophisticated in understanding where security risk actually sits. “Bitcoin infrastructure is much more simple, robust, security first,” he said.

Back said institutions are no longer trying to reshape Bitcoin into traditional finance infrastructure. Instead, he argued, they are adapting themselves to Bitcoin’s incentive structure and conservative security model.

That dynamic, he said, opens the door for Bitcoin-native tokenization and DeFi systems that prioritize safety over rapid experimentation, using layer-2 solutions such as Blockstream’s Liquid Network.

The three waves of bitcoin adoption

Back outlined Bitcoin adoption as occurring in three sequential waves: direct retail ownership, spot ETF access through brokerages and advisers, and now institutional allocation through managed portfolios, pension funds, and sovereign entities.

“The model portfolios that BlackRock and others are putting out,” he said, “those allocations haven’t taken effect yet,” suggesting the largest wave of institutional capital has not yet arrived.

Back also estimated roughly 200 bitcoin treasury companies now exist globally, including BSTR, the firm he leads as CEO.

He described BSTR as a more actively managed approach to bitcoin exposure, intended to generate returns through both holdings and fund management strategies rather than passive accumulation. The comments came as bitcoin traded above $81,000 at the time of the Consensus session.
