TON blockchain claims sub-second finality with Catchain 2.0 upgrade

Transactions on the Open Network layer-1 blockchain protocol previously took about 10 seconds to settle before the Catchain 2.0 consensus upgrade.

The Open Network (TON), an independent layer-1 blockchain that has integrations with the Telegram messaging application, said it has slashed block times to 400 milliseconds with the release of its Catchain 2.0 consensus upgrade.
