JPMorgan Report Calls Rise of Permissioned Blockchains the Biggest Threat to Bitcoin and Public Chains

JPMorgan recently said regulated, closed permissioned blockchains are gaining favor among financial giants because traditional financial institutions have strict privacy and compliance requirements. This shift could prove critical: if asset tokenization and settlement activity move to permissioned chains on a large scale, public-chain ecosystems could lose liquidity. That could even trigger a structural deterioration in the cryptocurrency market and exert long-term downward pressure on Bitcoin's price.

In a report published in July 2026, JPMorgan said cumulative transaction volume on its permissioned blockchain platform Kinexys had surpassed $4 trillion, underscoring the rapid growth of such parallel systems. Experts, however, have highlighted their limited ability to interoperate across blockchains. The two models could ultimately coexist in a hybrid system, with public chains transferring value across networks and permissioned chains handling regulatory and privacy requirements, potentially easing the long-term threat to Bitcoin and the broader public-chain ecosystem.
