This proposal propose the deprecation of node.sh for harmony validators.
introduction
For legacy reason, we used to use node.sh as a wrapper script of the harmony node binary with different network configuration support like testnet/mainnet. Since the release v2.3.4 (https://github.com/harmony-one/harmony/releases/tag/v2.3.4), the harmony binary supports the configuration file, so that the node.sh wrapper is no longer needed.
why now
- The v2.3.4 release had been released for 2 months. It supports
harmony.conffile for various network configuration. - The recent outage of
opendns.comhad caused node restart issue usingnode.sh - We are moving to open governance of network upgrade. The auto-update function of
node.shis no longer needed. - The auto-update function of
node.shis a centralized security risk that may cause massive node outage in the network.
what’s the action
All validators should stop using node.sh to run validator nodes. You may switch to use harmony binary directly, or use AutoNode.

what’s the plan
node.sh support will be completely removed by Q4 2020. The exact date will be set after the validator community approval of this proposal.
To update the harmony binary on the validator, we recommend following this repo to automate the process, https://github.com/Blockdaemon/harmony-deploy
If any community member would like to contribute to additional automation of validator update process, please submit your proposal and we’d like to provide a grant on it.
