Why? Has Jelurida moved to Bulgaria? They seem to attend a conference
there, but the watchdog should only monitor activities of Bulgarian companies.
In your last newsletters you mentioned child chain subnets several times. Is there information available how they are planned to be implemented? I searched the Web and didn't really find details about it.
The big question for me is how the incentive model would change if some nodes would be allowed to only process certain childchains (as part of the Ardor mainchain, in the form of ChildChainBlock transactions). For example: Would
forging nodes be allowed to process only certain childchains? From the point of view of security, these are the most important nodes (equivalent to miners in Bitcoin) and if they were allowed to process only some childchains, then incentives to process the whole chain are lowered, and maybe certain child-chain transactions would lack the necessary security.
For non-forging nodes I don't see problems with the approach as also light clients are allowed, and these nodes processing only certain childchains could be regarded as light clients (like the Ethereum light clients). But if forging nodes would have to process all transactions, then the hardware requirements for forging nodes would stay very high (as the number of active childchains and thus, transactions increases).
Because of these questions, I would like a detailed description of what is planned. (I may repeat this question in the NXT forum if it's not addressed here - I see few activity from NXT/Ardor experts at Bitcointalk).
