TON Core

Tonscan.org uses the Toncenter API

A great example of using the latest features of the Toncenter API is the popular blockchain explorer tonscan.org.

Using the Actions API, it shows user-understandable actions (such as “Swap on DeDust DEX” or “Domain Renew”) instead of raw account transactions.

Using Pending API it displays a list of pending transactions. By opening such a pending transaction we can see its progress in real time.

In the next updates, the Tonscan.org team plans to further simplify the UI.

Introducing the Pending API

Using this API you can track operations on the blockchain that have not yet completed.

As soon as an external message enters the blockchain, the Toncenter API Indexer notices it and builds a subsequent transaction series. Next, the action to be executed (e.g. "Swap on DeDust DEX") is recognized. As transactions are executed, the transaction series is re-indexed.

You can use this API to build responsive applications that respond quickly to user actions and show the progress of pending blockchain operations.

tonutils-storage 0.8.0

Optimized tonutils-storage to work with large files (1TB+), in anticipation of the beginning of distribution of network block archives via TON Torrents technology.

Release notes »

TOLK 0.10

This update lays the groundwork by addressing how fields will be serialized and how they relate to TL-B.

— Fixed-size integer types: int32, uint64, etc.
— Type coins and function ton("0.05").
— Types bytesN and bitsN (backed by slices at TVM level).
— Replace "..."c postfixes with stringCrc32("...") functions.
— Support 0b... number literals along with 0x...
— Trailing comma support.

The new version of TOLK is already supported by IntelliJ IDEA Plugin and VS Code Plugin.

TON Core: Report for February

A short month but not a short list of updates: node optimisation and detailed plan for further optimisations, finished research and development of TON/TVM sidechains, new functionality of Toncenter API in mainnet, TON Proxy, TOLK 0.9, alert bots for validators and much more.

https://telegra.ph/TON-Core-Report-for-February-2025-03-08

Upcoming Node Update 2025.03

The most important improvements are the acceleration of broadcasts in overlays (from TON Optimisation Roadmap) and the application of some solutions from the TON Core x Telegram block validation optimisation contest (up to 10% improvement).

TON Proxy: Introducing optional traffic micro-payments and privacy via garlic routing

We have updated the TON network protocols and TON Proxy technology, allowing traffic between client and server to pass through one or several intermediate TON Proxy nodes. Garlic routing ensures complete anonymity, safeguarding client privacy and enhancing server security.

Intermediate TON Proxy nodes can receive Toncoin micropayments through the TON Payment Network (Layer 2).

First of all, we did this to improve the protection of TON validators from DDoS attacks, and therefore to further improve the stability and performance of the TON Blockchain. However, the technology is also applied to TON Sites, TON Storage and TON Torrents.

Reducing End-to-End Latency in TON Blockchain

The TON Blockchain has demonstrated remarkable scalability, evidenced by its 50-fold growth over the past year and completed giant token minting events for gaming projects with multi-million user bases.

Last year, we introduced a significant Accelerator update designed to further enhance throughput, raise limits, and stabilize block generation times, independent of network load. This update was instrumental in achieving a world-record result during our performance tests. Currently, we are progressively implementing this upgrade across the TON mainnet.

In parallel, we have set a new goal: reducing End-to-End latency on the TON blockchain. End-to-End latency refers to the duration between sending a transaction and receiving the transaction result by the user.

Our conducted research, along with a detailed action plan — some elements of which have already been implemented — is available in the TON Optimization Roadmap.

Additionally, we're actively researching Sidechains and Layer 2 solutions for TON. For detailed information about recent developments in this area, please refer to the TON/TVM Sidechains Overview.

Note that the functionality to run a private Telegram bot is available in MyTonCtrl version 2.5.0.

Type update in MyTonCtrl console to update to newest version.

Introducing Telegram Bots with notifications for TON validators and nodes

We recommend that validator administrators use one or both bots to monitor their validators and receive alerts if a validator is having problems.

1. General bot @validators

This bot is for tracking the public status of the TON node/validator(s).

Supported alerts:

Telemetry

— Node is out of sync
— CPU is overloaded
— Node's db usage is more than 80%
— Network is overloaded
— Disk is overloaded

Fines

— Validator has been fined in the last validation round

Informational

— Alerts for validator's sent (or not sent) stakes

Network-wide

— Announcements
— Software update requests
— Requests for voting
— All approved complaints for the last validation round.

To start using it, open @validators and press /start.

2. A private bot that you can run personally

Supported alerts:

— Validator's wallet balance is less than 10 TON
— Node's db usage is more than 80%
— Node's db usage is more than 95%
— Validator had efficiency less than 90% in the validation round
— Node is out of sync on more than 20 sec
— Node is not running (service is down)
— Node is not answering to ADNL connection
— Validator has not created any blocks in the 6 hours
— Validator has been fined in the previous validation round
— Validator's stake has not been accepted
— Validator's stake has been accepted (info alert with no sound)
— Validator's stake has been returned (info alert with no sound)
— Validator's stake has not been returned
— There is an active network proposal that has many votes (more than 50% of required) but is not voted by the validator

Improved Metadata API

Last month we started providing metadata for Jettons and NFTs in the V3 API.

We are pleased to report a number of improvements:

— The metadata now enters the API in advance as soon as the token appears on the network. In the previous implementation, the metadata was indexed the first time the token was requested.

— Images and JSON are now proxied via toncenter.com. 3 image sizes are available, as well as original non-proxied urls for JSON and images. IPFS is supported.
Using a proxy increases security (you don't make requests to third-party hosting) and speed of downloading resources.

Support for extra-currencies in local ton-http-api

In ton-http-api v2.0.53, which you can install by yourself on your server, support for extra-currencies and a number of other improvements have been made.

Recall that earlier support for extra-currencies was made in the public Toncenter V2 and Toncenter V3 APIs.

Multisig Basic UI 1.02

— Support for sending arbitrary messages.
— Support for single-nominator operations.
— Additional orders and multisig security checks.
