Terra Classic is preparing for a major technical upgrade. The goal is to improve the network’s security, performance, and long-term reliability.
What is the Cosmos SDK
The Cosmos SDK is a software framework used to build blockchains. It is open source and allows developers to create both public and private blockchains. Public chains can use a Proof of Stake system where validators secure the network, while private chains can use Proof of Authority, where control is limited to selected validators.
Blockchains built using the Cosmos SDK are called application specific blockchains because they are designed for specific use cases. Terra Classic is one example of this. It currently runs on an older version, SDK v0.47.17. The proposed upgrade will move it to version 0.50.13.
Why the Cosmos SDK Upgrade is Important
Upgrading to SDK v0.50.13 brings several benefits:
● A more advanced system for handling transactions called ABCI++
● Stronger security, including fixes for known issues in the older version
● Better tools for developers to create and maintain applications
● A more flexible structure that makes it easier to manage upgrades
● Improved community control through governance-based settings
This upgrade also ensures that existing applications and features will continue to work without interruption. Terra Classic’s custom modules like Oracle, Market, and Treasury will be updated to match the new SDK structure.
What is the Wasm Module
The Wasm Module, short for WebAssembly Module, is the system that runs smart contracts on Terra Classic. A Wasm module is a precompiled unit of code that allows for fast and secure execution. It works across different platforms and provides the performance needed to support advanced applications.
Smart contracts are programs that automatically execute actions based on set conditions. They are an essential part of decentralized applications.
Currently, Terra Classic uses Wasm version 0.46.0. The proposed upgrade will move to version 0.53.2.
Why the Wasm Upgrade Matters :
● Smart contracts will continue to work as they do today
● Developers will be able to use the latest features and improvements
● Terra Classic’s custom smart contract connections, such as oracle and tax modules, will remain supported
This upgrade allows Terra Classic to stay compatible with the latest smart contract standards while keeping its existing contracts stable.
What Happens to Terra Classic’s Custom Modules
Terra Classic includes several unique modules that need special attention during the upgrade. These include:
● The Oracle Module, which tracks price data used in stablecoin systems
● The Market Module, which supports token swaps and liquidity
● The Treasury Module, which manages taxes and economic policy settings
Each of these modules will be carefully tested and adjusted. The development team will also add temporary tools to make sure everything continues to work correctly during the transition.
Why This Upgrade is Necessary
There are several reasons why this upgrade is important for Terra Classic:
● It removes old code and outdated changes made in earlier versions, as part of a broader effort led by Orbit Labs
● It fixes known security issues in the current software
● It gives developers modern tools to build more reliable and advanced applications
● It improves the network’s ability to adapt to future updates
This upgrade also ensures that developers and validators can work more efficiently, while keeping the network stable for everyday users.
Final Thoughts
Upgrading to Cosmos SDK v0.50.13 and Wasm v0.53.2 is an important step forward for Terra Classic. It makes the blockchain stronger, more secure, and easier to maintain without disrupting any existing features or applications.
For regular users, everything will continue to work as expected. For developers and validators, this upgrade provides a better foundation to build and innovate. Most importantly, it prepares Terra Classic for long-term sustainability and growth within the Cosmos ecosystem.
