Pakala
Pakala keeps the discipline of mining without the permanent energy race: block production costs burned coin, waits through verifiable delay, and expires after one chance.
Pakala separates the useful parts of mining: economic cost, verifiable time, and temporary eligibility.
The idea
Replace the race. Keep the cost and the clock.
Proof-of-work makes history expensive by spending energy over time. Pakala tries to make history expensive by burning the asset itself, then using a VDF to make time explicit.
The point is not free blocks. A producer still pays to compete. The difference is where the cost lands: inside the monetary system instead of in a continuous race for electricity and hardware.
The VDF is the protocol clock. It keeps fresh burns from becoming instant influence and gives every node a cheap way to verify that the required delay was actually crossed.
Why Pakala
A cleaner answer to what mining is for.
Real cost
Producing blocks should not be free. Pakala makes participation pay an irreversible burn.
Verifiable time
A VDF replaces the waiting function of mining with sequential delay that nodes can verify.
No stake memory
Tickets are one-shot. Old burns do not keep producing power over the future chain.
