TON Validators Prepare for Aug. 20 Collator Activation

TON Core said its “TON 2026.08” network update will switch on the collator architecture on mainnet on Aug. 17, 2026, moving block assembly to dedicated collator nodes while validators handle only verification. TON Status told validators to run specific commits — mytonctrl 7e90e26 and node 140320b — and be ready to vote at 08:00 UTC on Aug. 21 on configuration switches tied to execution and queueing.

Collators take over block assembly on TON mainnet

The handover changes where blocks are built, not who finalizes them. TON Core framed it as an efficiency shift drawn from its Accelerator work and adapted for Sub‑Second mode. By taking assembly off validators, the network targets lower latency during production. TON Core said in‑memory collators are expected to raise the maximum TPS on a single shardchain. The design separates assembly and verification to push throughput while keeping validator duties focused. The immediate effect on user‑seen speed depends on configuration toggles that follow the switch.
