filecoin-project/lotus v1.14.0-rc6

on GitHub

This is the sixth release candidate for the mandatory release v1.14.0 of Lotus that introduces Filecoin network v15, codenamed the OhSnap upgrade.

The OhSnap upgrade introduces the following FIPs, delivered in actors v7-rc1:

• FIP-0019 Snap Deals
• FIP-0028 Remove Datacap from Verified clients

Note:

• This release candidate includes the final proof params for Snap Deals.
• It only sets upgrade epoch for Butterfly-SnapNet and calibnet, and it does not set the upgrade epochs for mainnet.
• We are still expecting 1-2 more RCs before the final release.

Calibration Upgrade

The calibnet will be upgraded to Network v15 OhSnap at epoch 682006, around 2022-02-10T19:23:00Z.

To join the network, simply build lotus by running make calibnet.

New proof params for Snap Deals should be downloaded upon your nodes restart.

• The parameters are pinged on IPFS gateway https://proofs.filecoin.io and the CIDs can be found here, please let the lotus team know in #lotus-ohsnap if the params are not fetched automatically. You can also download the params manually from s3://proof-params-ap/filecoin-snapdeal-parameters/.
