We have been thinking about a similar approach using Ark.
The key advantage of this approach is that we can reduce the transaction-cost. A small miner that operates in the scheme above will receive a clunky set of many small VTXOs.
I don’t want to hi-jack this post and make it about Ark. However, a short summary won’t hurt anyone.
The mining pool can use OP_CTV to pay into a transaction tree. The leaf of this tree is called a VTXO. A miner can hold on to their VTXO’s for a while until they have collected a good amount of VTXO’s and offboard all funds at once.
This saves costs.
A small miner will not end up with 100 UTXO’s of 0.0001 BTC. Instead, they can offboard 100 VTXOs of 0.0001 BTC. Only a single UTXO worth 0.01 BTC will hit the chain.
