Changes to SelfConfiguration

[buckyroberts]

When making changes to SelfConfiguration, broadcast those changes to all known nodes. Banks also have to stream down those changes to users so that the Account Manager (and other clients) can update.

Nodes will send out signed PATCH requests when changes are made to the following fields.

Banks

• account_number
• default_transaction_fee
• version

Validators

• account_number
• daily_confirmation_rate
• default_transaction_fee
• version

Notes

• signed PATCH requests should also include modified_date to prevent malicious actors from rebroadcasting old data
• if a request is received with a modified_date earlier than the one you have stored for that node, request should be ignored

Miscellaneous

• nodes who aren’t connected don’t care about your changes
• additionally if they want to connect later on then they will be fetching your updated config then anyways
