FIP-0100: Removing Batch Balancer, Replacing It With a Per-sector Fee and Removing Gas-limited Constraints

[irenegia]

This FIP aims to enhance the efficiency and economic sustainability of the Filecoin network by removing batch fees from precommit and provecommit methods, introducing a per-sector fee for a more stable cost structure, and eliminating outdated protocol constraints made redundant by improved gas accounting.

Where is the discussion of this FIP?
Wouldn't daily_fee introduce more complicated logic? When SPs are earning income, some of their income is inexplicably reduced, and when they terminate, they have to destroy more. I don't think SPs will accept this.

@beck-8 the fip discussion is here #1105 (also linked in the table at the beginning of the FIP text)

Having a per sector fee instead of the batch balancer fee actually simplify the system offering more predictable cost.
Indeed the new per sector fee is not related to base fee value, its is a constant fraction of CS, which is more predictable and less "spiky".

About termination, we are actually considering a discount on having to pay the remaining of the new fee given termination fee is already applied. Thanks for pointing this out!

@irenegia Thank you for your reply.
Can you express in numbers how much this fee is? How much is the daily fee? How much is the 540-day sector fee? Is the batch fee higher or lower than before?

Proposed to give this FIP-0099 FIP-0100 - also a few open clarifications needed to confirm which implementation + design pathway is confirmed of the options proposed.

What are the cost and gas implications for an average miner sealing 100TiB daily under the proposed per-sector fee model compared to the current Batch Balancer?

Merging this PR to officially land this draft FIP - discussion may continue in #1105 and further details may be added to the specification via future PRs as implementation proceeds.
