Private chains solved a real problem when enterprises first adopted them: predictable performance, controlled environments, and the ability to meet internal or regulatory requirements without exposing early stage systems to public infrastructure The challenge now is scale. These networks have grown into long running systems while the broader ecosystem has shifted toward Ethereum aligned, rollup based architectures CDK Enterprise is the solution. Details in thread

Another point of friction is protocol drift. Many private chains freeze on an older fork or introduce small config differences that accumulate over time. As Ethereum advances, tooling, audits, and SDKs assume mainnet equivalent behavior Each divergence adds friction, like: • custom patches to indexers • unsupported tracing methods • unexpected differences in contract behavior

Enterprises need modern execution semantics, predictable upgrades, lower operational overhead, and the option to interoperate with the broader ecosystem when required CDK Enterprise provides that target environment and a proven, zero downtime migration framework for getting there
