TON is now 10x faster: Transactions in Just 3-5 seconds

The TON Core team has completed a major series of core optimizations for TON, planned for the first half of 2025. As a result, transaction finality under low to moderate network load has improved nearly tenfold - most operations now complete in just 35 seconds, compared to the previous 30-50 seconds.

Over this period, five updates were released, improving all key components of the network:
• Block validation;
• Cryptographic operations;
• Networking;
• Database performance;
• State serialization and deserialization.

Thanks to these changes, a single shardchain can now handle the current load of the mainnet - previously, up to four shards were needed. This means most operations - like token transfers or DEX swaps - are now processed within a single block, without cross-shard interaction.

Under high load, the blockchain will still scale via sharding, also implemented significant stability improvements for peak periods.
