@SatoshiSingh PoLW sounds like a hybrid of PoW and proof of burn. I agree with befreeandopen that proof of burn is basically a form of proof of stake. My conclusion from
this exploration is that hybrid protocols are a dead end because hybrid protocols have one weaker link that's easier to attack.
In this case, miners are burning coinbase rewards. The proof of stake is the burn itself. However, a miner would only burn coins if doing so lead to greater rewards in the future. So the burned coins are in fact actually earned, and still have value. Therefore I would think that miners would still do an amount of work totaling up to the full value of the block reward, regardless of whether they burn it, because any burnt coins should be expected to lead to more coins in the future than were burned. What am I missing?
