v1.18.0-rc2

IMPORTANT: Users syncing the calibration test network MUST use this RC or higher -- Lotus v1.18.0-rc1 will NOT sync the calibration test network correctly.

This is the second release candidate of the upcoming MANDATORY release of Lotus that introduces Filecoin network v17,
codenamed the Shark upgrade. Shark upgrade delivers a wave of protocol refinements that will allow for useful smart contracts to be written using the FVM (eg. programmable markets, lending contracts, etc.).

A full changelog will be published upon final release.

The Shark upgrade introduces the following FIPs, delivered in actors v9:

• FIP0029 Beneficiary Address for Storage Providers: step towards better lending market for SP
• FIP0034 Fix PreCommit Deposit Independent of Sector Content: resolves a significant weakening of Filecoin PoRep’s security guarantees
  • ❗Pre-commit deposit will be calculated as the 20-day projection of expected reward earned by a sector with a sector quality of 10 (i.e. full of verified deals), regardless of sector content. Leave the initial pledge value, due when the sector is proven, unchanged.
• FIP0041 Forward Compatibility for PreCommit: enables a cleaner and easier transition to Programmable Storage Markets
• FIP0044 Standard Message Authentication: enable metadata authentication for user defined actor
• FIP0045 Decoupling Fil+ from Marketplace: DataCap and the QAP it brings is now associated with DATA. DataCap for the data many have terms where anyone who cares about that piece of data may extend the term, which incentives SPs to store the data longer on the network
  • HUGE step towards user programmable storage market
  • ⭐️ First Fungible Token Contract - Datacap Actor, on Filecoin! (fungible token standard, token contract library)
