Ultra Light Nodes
When running without a blockchain connection, bandwidth incentive payments (SWAP) cannot be made so there is a risk of getting blocklisted by other peers for unpaid services.
Configuration
In order to run an ultra-light node use the same configuration as for the light node but leave the blockchain-rpc-endpoint parameter value to empty (or just comment it out).
Make sure you set the swap-enable configuration parameter to false, otherwise you will get an error.
Mode of Operation
The target audience for this mode of operations are users who want to try out running a node but don't
want to go through the hassle of blockchain onboarding. Ultra-light nodes will be able to download data as long as the data consumed does not exceed the payment threshold (payment-threshold in configuration) set by peers they connect to.
Running Bee without a connected blockchain backend, however, imposes some limitations:
- Can't do overlay verification
- Can't do SWAP settlements
Since we can't buy postage stamps:
- Can't send PSS messages
- Can't upload data to the network
