NEAR Protocol Teases Next Major Protocol Upgrade, SPICE, Reducing Block Time to 200ms

June 22, NEAR officially announced its next major protocol upgrade: the SPICE (Separation of Consensus and Execution) proposal, a critical milestone toward Nightshade 3.0. Once fully rolled out, NEAR will cut its block time from 600 milliseconds to 200 milliseconds — a roughly 3x speed improvement, approaching the upper speed limit allowed by physical constraints. At the heart of SPICE is the decoupling of the consensus layer from the execution layer. This lets validators finalize block consensus without waiting for transaction execution, reducing latency and enabling support for more complex, time-intensive transactions. NEAR noted this upgrade will be the largest underlying architecture overhaul since Stateless Validation launched in 2024. Post-implementation, transaction experiences for apps like NEAR Intents and near.com will see notable improvements. Alex Shevchenko, CEO of Defuse Labs, added that NEAR’s final confirmation time is expected to drop to roughly 0.4 seconds — faster than Visa’s standard ~3 seconds — bringing the network’s payment experience close to “instantaneous.” NEAR also highlighted that faster block times are foundational to the AI Agent economy, enabling high-speed payments and complex transactions between autonomous agents, plus the ability to run longer tasks across multiple blocks. Additionally, SPICE will clear the path for Nightshade 3.0, laying the groundwork for future cross-shard atomic execution. The NEAR development team explained this will help mitigate development complexity and potential security vulnerabilities stemming from asynchronous network environments, boosting both the network’s scalability and security.
