[Informative] Proactive Security Measures: Temporarily Disabling XDCx Feature for Enhanced Chain Security

Liam — Sat, 09 Mar 2024 13:37:11 +0000

Important Security Update and Verification Process

As part of our ongoing commitment to security and transparency, we recently conducted a thorough audit of our network features. During this audit, we identified certain vulnerabilities within the XDCx feature. We want to clarify that this feature has not been released to our community and there are no immediate plans for its release.

In light of these findings, we have decided to temporarily disable the XDCx feature. This proactive measure is to ensure the continued security and integrity of our blockchain network. Our team is dedicated to resolving these vulnerabilities and will provide updates as we progress.

Verification Process

In response to these findings, we employed a detailed verification process to assess the impact on the current Mainnet. Utilizing a specialized script, we scrutinized all transactions for any interaction with the following addresses associated with the XDCx feature:

xdc0000000000000000000000000000000000000091
xdc0000000000000000000000000000000000000093
xdc0000000000000000000000000000000000000094
xdc0000000000000000000000000000000000000028
xdc000000000000000000000000000000000000001e
xdc0000000000000000000000000000000000000029
xdc000000000000000000000000000000000000002a

We are pleased to report that our investigation revealed no transactions related to the XDCx feature on the Mainnet.

Moving Forward

Our team is dedicated to ensuring the safety and reliability of our blockchain. We understand the importance of these features to our community and are working diligently to address these issues. Once we are confident in the security and functionality of the XDCx feature, we will consider its future release.

We appreciate your understanding and support as we continue to improve and secure our network. Your trust and security are our top priorities.

[Informative]XDPoSChain Git Workflow

Liam — Tue, 08 Aug 2023 12:22:26 +0000

Repo: https://github.com/XinFinOrg/XDPoSChain
I would share the current Xinfin main blockchain git workflow for anyone who wants to contribute. This will include branch placement and testing network also tagging process.

Key Points:

Always fork from dev-upgrade unless you are doing hotfix
Quarterly merge from dev-upgrade to master will including 1 and more changes.
Community Approval can take longer for months or more then year.
Protocol Team will help mainly on PR review and Tagging on github.

[Informative]Things to test when you apply hard fork upgrade

Liam — Tue, 01 Aug 2023 12:05:39 +0000

Things to check when you are applying hard fork upgrade.

There are few jobs and check points to increase the confidence of your code change.
Test Your change on devnet:

Step 0:

Merge your change into dev-upgrade branch. And update your hard fork block number. Code will auto deploy to devnet.

Step 1:

Apply your hard fork block ahead of current block and witness before and after. Blockchain grows as usual.

Step 2:

Create one node from your end, synchronize from the scratch to new change state.

Step 3:

Check Miner log whether there is error pumping out.

Ask protocol team to check devnet's log.
Check your local node logs

Step 4:

Check related API returning new data.
