Hedera is announcing the deprecation of the insecure Hedera Consensus Service (HCS) mirror node endpoints. This change is part of our ongoing commitment to enhance security and ensure the reliability of our services.
The APIs have transitioned from the legacy hcs.<env>.mirrornode.hedera.com:5600 endpoints to the new <env>.mirrornode.hedera.com:443 endpoints. Older SDK versions are also affected by this change as they use the legacy HCS mirror node endpoints.
The deprecation will impact the following groups:
In general, anyone relying on the gRPC port 5600 to access HCS mirror node endpoints should prepare for this change.
Initial Notifications: Week of June 10th
Mid-cycle Reminder: Week of September 9th
Actual Deprecation: Week of November 11th (6 months from the initial notification)
The deprecation of the HCS mirror node endpoints is a positive step towards:
Enhanced Security: Deprecating the insecure gRPC port and domain in favor of secure TLS domains and ports.
Improved Reliability: Ensuring all traffic is routed through secure and reliable channels.
By upgrading to the new endpoints, users will benefit from increased security and stability, ensuring a better overall experience when interacting with Hedera services.
We appreciate your cooperation and understanding during this transition period. If you have any questions or need support, please reach out on Discord.
