From e288074183110f8db3a4f04aa97d130d297c71bc Mon Sep 17 00:00:00 2001 From: Florent Tapponnier Date: Thu, 16 Jul 2026 22:18:33 +0200 Subject: [PATCH] docs(subsecond): add third-party live verification of ~1s finalization lag Add a Callout tip below the finalization table pointing readers to a live third-party benchmark (OpenChainBench L1 finality) that independently measures the TON masterchain commit at ~0.4s p50 via tonapi.io. This confirms the ~1s finalization lag claim from the table using an external source and clarifies that the benchmark lists TON under the Gram ticker following the community rename vote. --- content/subsecond.mdx | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/content/subsecond.mdx b/content/subsecond.mdx index 02b136c35..b6a0dabdb 100644 --- a/content/subsecond.mdx +++ b/content/subsecond.mdx @@ -23,6 +23,11 @@ As of April 9th 2026, mainnet runs with a block interval of about 400 ms instead - Together with the consensus update, the [Streaming API v2](#ton-center-streaming-api-v2) delivers status updates with 30 to 100ms latency. - Testnet remains the primary environment for project testing. + + **Third-party verification.** [OpenChainBench](https://openchainbench.com/benchmarks/l1-finality) is an open-source, live benchmark that independently measures TON masterchain finalization (listed under the **Gram** ticker following the [rename vote](https://ton.vote/EQDQvywF226NXojPky_9gwbCz0FPoygqY11bGl03SONNBs5V/proposal/EQAv-VS2OM80SYLB0ouRWRcpFg4J0L-egUf1-utF-OJ6h0rK), via `tonapi.io`) at **~0.4 s (p50, 24h)**, which confirms the ~1 s finalization lag target above.
