@vjy Nothing is stopping you from mining your own transactions without a fee, except centralised miners.
@lukedashjr what's proof-of-node other than proof-of-storage (utxo)?
One way is, node identity.. use utxo to identify nodes + PoS (nothing at stake, except utxo is 30 days old)..
Say, for example, ₿100k linked to nodes, and nodes can send 100k (1% of 10M) tx for free, then ₿1 node can send 1 no-fee tx per month, and so on
