Introduction: Big Upgrade on the Polygon Network

On July 10, Polygon will undergo a major transformation with the launch of Heimdall v2. According to Sandeep Nailwal, co-founder of Polygon, this is an important milestone in the history of Polygon PoS.

This update not only increases transaction speed but also fixes various long-standing technical issues. With the change in consensus infrastructure from Tendermint and Cosmos-SDK v0.37 to CometBFT and Cosmos-SDK v0.50, the network is expected to become more efficient and secure.

Technical Changes and Benefits

The Heimdall v2 update brought significant changes to Polygon’s consensus infrastructure. By switching from Tendermint to CometBFT, as well as updating Cosmos-SDK from version 0.37 to 0.50, Polygon eliminated obsolete code and significantly improved network performance.

This change is expected to reduce the transaction finality time to around five seconds, which means transactions will be faster and more secure. In addition, with faster finality, the block reorganization that occurs will not exceed two blocks.

This will speed up checkpoint creation, strengthen the security of bridges between networks, and improve the overall user experience. While there were some caveats during the upgrade window, such as a potential three-hour delay in finality, the long-term benefits offered by Heimdall v2 seem to overcome those short-term challenges.

Impact on Node Operator and Market

For node operators, the migration process is expected to take about 30 minutes on the mainnet. They will need 20 GB of RAM and double the current disk space for Heimdall. While most validators have already upgraded, those who have not are advised to test and prepare their systems immediately.

The market has also responded positively to this upgrade announcement. Polygon’s native token, POL, has risen more than 9% in the last 24 hours, with a trading value of around $0.20. With the market capitalization now at $2.11 billion, this increase shows investor confidence in Polygon’s long-term potential as an Ethereum scalability solution.

Conclusion

With Heimdall v2, Polygon not only improves finality but also cleans up long-standing ‘technical baggage’. This upgrade marks a new phase in Polygon’s evolution as one of the scalability solutions for Ethereum (ETH), promising increased speed, security, and efficiency. The community and investors seem to have many reasons to be excited about Polygon’s future.
