Ava Labs Proposes Astra Upgrade to Enhance Subnet Architecture on Avalanche
The Astra upgrade aims to improve the independent operation of Avalanche subnets from the main blockchain.

Ava Labs proposes Astra upgrade to enhance subnet architecture
Ava Labs, the developer behind Avalanche, has proposed phased architectural changes for subnets in an upgrade named Astra. The goal is to enhance the autonomy of applications running on subnets, allowing them to operate independently from the main network.
The upgrade proposal was authored by Patrick O’Grady, Head of Technical Team at Ava Labs. He detailed a phased approach to customize subnet functionalities. If approved and implemented in the coming months, this upgrade aims to strengthen subnet operations within the Avalanche network.

The proposal for the Astra upgrade altering subnet architecture is published on GitHub.
Subnets are customized child blockchains within the Avalanche ecosystem, connected to the Avalanche blockchain but not sharing resources. Developers of each project have complete control over their user experience.
First Phase - Improving the relationship between the main Avalanche network and subnets
Before the upgrade begins, subnet validators are required to confirm not only the main network (X-Chain, P-Chain, C-Chain) but also any additional subnets they are interested in.
With the upgrade implemented, subnet validators will focus solely on running a subnet and synchronizing its P-Chain. This narrowed focus reduces computational and hardware requirements, thereby lowering participation costs. The upgrade essentially eliminates the need for subnet validators on the main network.
“By not requiring Mainnet validation, the demand for subnet initiation and synchronization of C-Chain and X-Chain can be relaxed. Subnet validators will only need to synchronize the P-Chain to monitor any changes to their subnet validator set for cross-subnet communication,” said O’Grady.
Next Phase - Shifting subnet validation model from staking-based to fee-based
Instead of previously requiring a staking of 2,000 AVAX ($22,000 USD), a new “pay-as-you-go” validation fee in AVAX will be implemented. This fee can be adjusted and varies depending on the number of validators in a specific subnet. This change introduces a flexible pricing mechanism, billed continuously, eliminating the need to lock or stake a large amount of AVAX upfront.
The Astra upgrade is not Ava Labs' first initiative to enhance its subnets. The "Banff 5" upgrade in late 2022 introduced features such as Elastic Subnets and Avalanche Warp Messaging. Building upon previous advancements, the Astra upgrade aims to further refine the adaptive capabilities and functionalities of the network.
Ava Labs stated that the Astra upgrade for Avalanche could help bring subnets to a broader market, not only cryptocurrency enterprises but also traditional businesses aiming to build on-chain products and services within their ecosystems.
Following the news, AVAX price showed minimal fluctuations and continued trading around $11.2 USD.
