🔧 Introducing TON Replay

As our blockchain ecosystem thrives with countless developers and projects, evolving becomes a cautious task. Changes could unpredictably impact the ecosystem, making upgrades a slow and meticulous process. Often, theoretical issues might not even affect real-world applications.

🌟 But, there's a breakthrough! TON Core has launched the TON Replay project to tackle this challenge. The first fruit of this initiative is TonTVMReplay, developed by DTON. This tool emulates historical transactions on updated versions of the TON Virtual Machine (TVM). This means we can now test how real projects react to upgrades or network configuration changes before implementing them, ensuring smoother and safer evolution.

🔍 Looking Ahead: TON Replay isn't stopping there. We're developing advanced features for smarter checks. The goal is to ensure the practical outcomes of transactions—like transfers, swaps, and more—remain consistent, even if the transactions themselves change. This will enable us to run mirror networks and make significant, yet safe, modifications to the transaction executor.

🛠 More from DTON: Besides TonTVMReplay, DTON is also behind other developer-friendly projects, such as their blockchain index dton.io and the recently launched LSaaS (liteserver-as-a-service) via @liteserver_bot.

🏆 MyTonWallet Contest for iOS Developers

Prize fund: up to $25,000
Deadline: 23:59 on March 28th (Dubai time)
Results: April 12th, 2024

The Task is to implement the new design for MyTonWallet as a new Swift app based on the provided mockups and archive with animations. Your submission must precisely represent the provided design – this includes all elements, their proportions and position on the screen, as well as their animations and transitions.

Required Functionality (Screens)
1. Auth Flow, including both creating and importing wallets.
2. Main Screen listing all user's tokens and recent transactions.
3. Transaction Info Modal featuring several transaction types.

Details
While the task involves developing a new Swift app, some existing code from our current JavaScript app must be reused. Specifically, the API and blockchain integrations (which is already standalone and currently exposed as a web worker). To achieve this, a bridge must be implemented to allow running JavaScript process from the Swift environment (e.g., in an invisible WebView). This approach enables leveraging our existing API abstractions and focusing on the UI part without delving deeply into blockchain-related programming.

Evaluation Criteria
During the evaluation stage our judges will test the submissions on a broad range of iOS devices. The key factors that will be used to determine the best apps are:

· The general aesthetics of the app.
· Adherence to the provided mockups and design elements.
· Attention to the tiniest details in the user experience.

The smoothness of animations and the overall stability of the app will play a major role. Last but not least is the absence of significant flaws (including crashes, performance issues, battery drains, visual glitches, noticeable element blinking, layout imperfections and more).

Submissions
Contestants will be able to submit their entries to @MyTonWalletBot. We will further clarify the submission instructions closer to the deadline.

@ton/core update 0.56.2

Fixed cell serialization and hashes calculation for PrunnedBranch exotic cells.

Developers, please pay attention to cell hashes in your projects.

tonutils-go v1.9.1 released, please update

Update is needed because:
A new version of LiteServer has been deployed to the testnet that changes the way it proves block shard information for GetBlockShardsInfo method. This update removes the state proof in the second root and uses only a single root with block proof. As a result, this new LiteServer version is incompatible with previous versions of LiteServer and proof verification of GetBlockShardsInfo fails.

v1.9.1 supports both LS versions, it is safe to update for both networks

Smart contract libraries

TON smart contract developers, you can use smart contract libraries to optimize the network fees of your smart contract, in particular the storage and forward fees.

Libraries are applicable if you have multiple instances of a smart contract that have common data.

The common data (e.g. smart contract code) can be stored in the library, and the smart contract will only reference it.

You can find an example of how to use this functionality in the new Jetton-with-governance and Multisig 2.0 smart contracts.

Efficiency of TON blockchain state storage

We would like to draw attention to the beauty of the TON architecture.

Even without libraries, serialized data in the blockchain is automatically compressed, which means that the same data cells are deduplicated.

This fits well with the guidelines of writing distributed smart contracts on TON - not to make a single huge smart contract that is a bottleneck, but to make many small actors. Identical cells of instances of the same smart contracts will be stored once, so the final blockchain state is not bloated.

Introduction of precompiled smart contracts

New functionality will be introduced in the next node update.

The code of the most popular smart contracts can be written in C++ and embedded in node.

Since such precompiled smart contracts do not need to run TVM to execute, they consume less resources and therefore their network fees can be reduced.

It is planned to offer validators to apply this optimization to the new Jetton-with-governance smart contract.

Next step is introduction of refreshed Jetton smart contract code (fully compatible with the old Jetton of course) and propose to make it precompile as well.

In order for the precompile optimization to apply, validators need to vote for each smart contract type. Note, that precompiles can be activated step-wise: first by activating new cost rules and then by activating embedded code execution.
