With proposal 136899, the queue size for key derivation requests accepted by subnet fuqsr for the key vetkd:Bls12_381_G2:test_key_1 will increase from 10 to 20. As noted in an earlier post, the initial limit was set conservatively to support preliminary testing. Based on the results, we are now confident that the subnet can sustain a higher number of parallel requests, and we are proposing to increase the queue size to 20, aligning it with the limits used by other chain keys. Further adjustments may follow as adoption increases and additional usage patterns emerge.

If adopted, the new chain key config of the subnet will look like the following:

ChainKeyConfig {
            key_configs: [
                KeyConfig {
                    key_id: Some(
