With the August 17 update, TON mainnet validators transitioned to a new collator-based architecture. The update has been running stably on mainnet.
The rollout of planned limit increases began on August 27. The first change raised
leader_window from 4 to 16.Single-shardchain performance tests
Two tests were conducted on mainnet to measure single-shardchain performance using a workload that simulated jetton transfers:
— August 25, approximately 10:30 UTC: an input load of approximately 1,200 TPS.
— September 4, approximately 11:30 UTC: an input load of approximately 1,500 TPS.
In the latest test, a single shardchain processed 600–650 TPS in sub-second mode for this workload. As the input load increased further, the shardchain split into two. After split operation latency increased, but the block production rate remained stable.
Next steps
Work to increase single-shardchain performance will continue. The current target is 1,000–2,000 TPS per shardchain.
As a reminder, single-shardchain throughput is not the throughput limit of the entire TON blockchain. TON can run many shardchains in parallel, allowing the network to scale beyond the capacity of any individual shardchain.
