Worked on the paseo-network/runtimes repository to enhance migration governance security within the blockchain runtime. Focused on implementing stricter authorization controls for state trie migrations, the developer enforced MigController authorization and updated the ControlOrigin logic to require both EnsureSignedBy<MigController, AccountId> and EnsureRoot<AccountId>. Additionally, the MigController was reverted to a specific parity account, ensuring that only authorized entities could initiate migrations. All changes were recorded with audit-ready commit logs to support future traceability. This work leveraged expertise in Rust, blockchain development, and runtime development, resulting in a more robust governance posture and reduced risk of unauthorized migrations.
