Validator Restore-from-Backup functionality — January Highlight

With new functionality in MyTonCtrl validator tool the validator administrator can quickly bring up a validator on another server and switch to it. For example, in case of force majeure in the data center where the validator was located.

Better discovery of changed nodes' IPs in TON 2025.02 complement this update.

Validator support for Prometheus metrics — January Highlight

We have received many requests from the community to support the popular Prometheus monitoring system.

With new functionality in MyTonCtrl validator tool the validator administrator can collect validator metrics in Prometheus.

Remote validator controller — January Highlight

Now MyTonCtrl validator tool can be installed on a separate server other than the server on which the vailadator is running. Some validator administrators may find this functionality useful for security reasons, easy migration of the validator to another server, or other reasons.

Introducing the Domain API

Now the /accountStates method returns the TON domain bound to the specified account in the address_book field.

In other methods, such as transaction list, you will also find domains in address_book.

In case there are several domains bound to an account, the shortest one is returned.

Mainnet API

Introducing the Action API

The Toncenter Indexer now recognizes user-friendly actions among transaction series, such as staking, exchanging Jettons on DeDust DEX, or sending NFTs. A set of filters is available.

Supported Actions:

Basic
— Toncoin transfer
— Call contract
— Contract deploy

System
— Deposit stake to elector
— Recover stake to elector
— Tick-tock

Jettons
— Transfer
— Burn
— Mint

NFT
— Transfer
— Mint

Nominator Pool
— Deposit
— Withdraw

@stakee/TonStakers
— Deposit
— Withdraw

DeDust DEX
— Swap
— Add liquidity
— Withdraw liquidity

Ston-fi DEX
— Swaps v1
— Swaps v2
— Add liquidity v2
— Withdraw liquidity v2

NFT Auctions
— Bidding (Fragment, Getgems)

TON DNS
— Renew domain
— Change DNS record
— Delete DNS record

W4R2 Toncoin Subnoscriptions
— Subscribe
— Unsubscribe

The Toncenter team will continue to work and will be adding new action types in the next versions.

Also the /trace method now supports the incude_actions=true parameter, which will also return a list of actions related to this transaction series.

Mainnet API

Testnet API

Introducing the Emulation API

Using this API you can simulate the result of sending a message to the blockchain, before sending it.

The API predicts not only raw transactions, but also recognizes known user-friendly actions among them.

This will allow the user to see what happens if they sign the send, as well as estimate the total fees.

Mainnet API

Testnet API

The new Domains, Actions, Emulation functionality in the Toncenter API is made to improve the overall UX of the TON ecosystem.

Products and services can show user-understandable actions (such as “Exchange 1,000 USDt to TON on DeDust DEX”) instead of raw transactions, show what happens before sending a message to the blockchain for the user's convenience and safety, and make greater use of TON and .t.me domains.

Multisig Basic UI 1.02

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

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.

https://github.com/toncenter/ton-http-api/releases/tag/v2.0.53

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.

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

Private notification bot documentation »

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.

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.

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.
