on GitHub

This is the first 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 is built on top of lotus v1.13.2. Enterprising users like storage providers, data brokers and others
  are recommended to test out v1.15.0-rc1(coming on Jan 18th, 2022) for latest new features, improvements and bug
  fixes and be ready for the upgrade!
• This release candidate uses temporary proof params for Snap Deals.
• It only sets upgrade epoch for Butterfly-SnapNet, and it does not set the upgrade epochs for calibration and mainnet.

Butterfly - SnapNet

The ButterFly-SnapNet will be upgraded to Network v15 OhSnap at epoch 30262, around 2022-01-17T19:00:00Z.

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

The network supports three sector sizes, 512MiB, 32GiB and 64GiB. Temporary proof params for Snap Deals should be downloaded upon your node restarts.

• The parameters are pinged on IPFS gateway https://proofs.filecoin.io/ipfs/ 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/.
• For users that are in China: export IPFS_GATEWAY=https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/ to get params fetched from jdcloud.
