Have you thought of the international limit you're going to set on how much a node can hold on your network?

At current, I think I worked out a resync of every 2 weeks (the point where a new utxo is made) would take 0.5btc to be able to confirm within that time with neutral luck.

Hashrate current: https://www.coinwarz.com/mining/bitcoin/hashrate-chart
Current cost per phs https://www.nicehash.com/pricing

Values given are 116EHs and 0.0062/phs

116000x0.0062=719.2btc to take over the whole network for a day (obviously this is theoretical).

719.2btc/(144*14)=0.357btc

Thus, at 3000 transactions a block, each channel at the moment should be limited to 0.0001btc?
