Hello Consensus and Collection Node Operators,
Transaction fees have increased on Flow. Please see the announcement here:
https://forum.flow.com/t/upcoming-mainnet-update-transaction-fee-changes-going-live-on-monday-dec-8th/8427/2
To ensure uninterrupted operation, please fund the machine accounts associated with your Consensus and Collection nodes as soon as possible, with at least 2 FLOW. The machine account is different from your staking account. You can read more about machine accounts here.
With the updated fees, transactions submitted by these nodes will cost more, causing machine accounts to deplete faster.
You can find your machine account address in the file:
bootstrap/private-root-information/private-node-<your-node-id>/node-machine-account-info.priv.json
Example:
cat /var/flow/bootstrap/private-root-information/private-node-info_8adde2ecac9416bea12940c5a376abf5bc043fed5c5983be4abd3dab4248cdf2/node-machine-account-info.priv.json
{
"Address": "0xf81465e23090eb86",
…
…
}
You can check the balance on flowscan.io or through flow cli (flow accounts get <access address> -n mainnet)
Deadline: Please complete these updates by Tuesday, Dec 8th EOD in time for epoch transition on Wednesday, Dec 9th.
Additionally, please update your alerting thresholds as follows:
Collection:
- Minimum: 0.25 FLOW
- Recommended: 0.75 FLOW
Consensus
- Minimum: 2 FLOW
- Recommended: 6 FLOW
If you have not setup monitoring for machine account balance, please see the earlier announcement and set it up now. Please ensure that you alert on both,
machine_account_balance < machine_account_recommended_min_balance
and
machine_account_is_misconfigured > 0
No action required for other node types.
Thank you,
Flow Team
