• is processing 0.00 transactions per second, yet blocks are being produced (1.28 per second). What do these blocks contain if not transactions?

Subnet Management - 4zbus (Application)

Blocks are created irrespective of whether there are messages to be included. This makes sense because at the time of block making, we don’t even actually know if there is stuff to execute, because not everything comes in via blocks, canisters can also do work on their own via heartbeat or timers. We need to regularly have a new block to trigger a new execution round which then may execute those heartbeat/timer messages. Wrt why this subnet has essentially no load: not all subnets are made avai…

• is burning cycles periodically, but there are no canisters running. Can I ask what the cause of these burnt cycles and transactionless blocks is?

The cycles are being burnt through threshold ECDSA and Schnorr signatures. For every tECDSA/tSchnorr key, there is typically only one subnet that creates signatures with that key, and signing requests are routed to that subnet. fuqsr is the signing subnet for the test ECDSA and schnorr keys. What happens is that certain canisters on other subnets request signatures, which are routed to fuqsr where the signature is created, leading to the cycles being burnt there.
