Privacy features will create stronger competitive advantages than performance improvements for blockchain networks in 2026, according to a new trends report from a16z crypto. The research identifies privacy as the critical factor that could determine which cryptocurrencies dominate the market this year.
What Happened: Privacy Networks
a16z crypto released its 2026 trends report identifying privacy as the critical feature that will separate winning blockchains from losing ones. Daejun Park and other analysts at the venture capital firm predict privacy will become the most significant competitive advantage for blockchain networks this year.
Ali Yahya, a general partner at a16z crypto, argues that privacy creates network lock-in effects that public blockchains cannot replicate.
The research notes that bridging tokens between chains is straightforward when transactions are public, but moving assets while maintaining privacy proves far more difficult.
Crossing boundaries between private and public chains leaks metadata including transaction timing and size correlations that can expose user identities.

Why It Matters: Competitive Advantages
Privacy networks could develop winner-take-most dynamics because users face higher switching costs compared to public blockchains.
The report suggests that general-purpose chains without privacy features, thriving ecosystems, or distribution advantages will struggle to attract users or developers.
Adeniyi Abiodun, chief product officer at Mysten Labs, emphasizes that industries like finance and healthcare require confidential data handling. He proposes secrets-as-a-service infrastructure that would provide programmable data access rules and client-side encryption enforced on blockchain networks.
Shane Mac, CEO of XMTP Labs, adds that decentralized messaging systems need open protocols rather than private servers controlled by single companies.
