TON Core - Report for May 2025

TON Core

Kernel

TVM 11 in the Testnet

Extension of the c7 registry to enable the creation of more optimized smart contracts; new account storage statistics for the “Accelerator” update.

Planned to be implemented in the TON mainnet in June after testing in the testnet.

Full Changelog

Accelerator 3/3 in the Testnet

After resolving the Block Retention issue, we began testing the third and final part of the “Accelerator” update on the testnet. At the moment, one validator (on the accelerator branch) with two separate collators are already functioning in the TON testnet.

At the end of June, after testing on the testnet, we plan to roll out the final part of the "Accelerator" to the TON mainnet.

Upcoming new optimizations

Work is underway to optimize the serialization of large blockchain state, which, together with previous made optimizations, will allow the TON mainnet to be automatically merged into 1 shard when there is no heavy load. This means that without significant load, operations (such as exchanging coins on the DEX) will take 3-5 seconds.

This work is scheduled to be completed in June.

Node and Validator Tools

We would like to thank the validators of the TON mainnet for participating in the vote on May 5 to update the protocol version. The vote was accepted.

Partial archive nodes

Previously, archive nodes stored the entire history of the blockchain. Considering that the history is already quite large, and that with new optimizations we intend to reduce the block creation time (accordingly, the number of blocks to be stored will increase), we have made the following improvements:

Now, the full/archive node can sync and store a specific time period, rather than the entire blockchain history. This allows you to split the storage of the blockchain history across different nodes.

In the new mytonctrl 2.6.0 version, you can select in a convenient user-friendly installer which mode you want to run the node in and which block range it will store.

Downloading archive blocks and states via TON Torrents

Now, downloading archive blocks and archive states of the blockchain can be done via TON Torrents (TON Storage), which speeds up the process and allows you to download from multiple peers.

We have launched a dump service that automatically converts new block bundles and states into TON Torrents bags and makes them available for download.

mytonctrl 2.6.0 natively integrates the function of downloading blocks and states via TON torrents during the initial sync. If you wish, you can download blocks and states even using the TON Torrents app.

Validators web dashboard

The Toncenter QOS (Quality of Services) API has been updated with additional information about validators (country, node version, mytonctrl version, smart contract version) and a Web Dashboard for Validators https://validators.ton.org has been created based on it.

The dashboard displays a list of validators (index, work efficiency, weight, stake, software versions, addresses) in the current or specified validation round, round information, and network configuration.

Validator administrators can monitor the performance of their validators on this dashboard, along with the @validators alert system.

API

Streaming API - Websockets/SSE for Enterprise Plan

We’re excited to announce that Toncenter has launched a Streaming API! This API enables real-time updates about pending and committed transactions and actions, filtered by specified addresses. The API supports both Server-Sent Events (SSE) and WebSocket protocols, offering flexibility for integration.

Currently, the Streaming API is available exclusively to Enterprise clients. In particular, the non-custodial wallet MyTonWallet has already begun to implement this feature for instant display of incoming transactions.

The Streaming API will soon be available to everyone.

Documentation

New actions supported

Tonco.io DEX supported in the Toncenter Actions API:

New provider "tonco" added to existing DEX actions: jetton_swap, dex_deposit_liquidity, dex_withdraw_liquidity; tonco_create_pool action added.

Get-methods IDs

Now, the /accountStates response returns a list of smart contract get method IDs. Based on the presence of certain get methods, you can determine the type of some smart contracts. Adding get method indexing has also improved the accuracy of our Actions API.

tonscan.org uses Toncenter Actions V2

Based on Toncenter Actions API v2 update, the popular blockchain explorer tonscan.org has start to display operations with multisig, vesting, EVAA, and Jvault services.

It is also worth noting the extended support for multisig: the explorer now displays a list of signers, proposers, multisig info and the contents of the multisig order that will be executed after signing.
