The Filecoin Mainnet will be performing a Network Upgrade to v20, codenamed Thunder, at epoch 2870280 around 2023-05-18T13:00:00Z!
This is the second upgrade in the two-staged incremental network upgrade. The first part of rolling out FIP-0061 - which introduces a new proof that reduces the grindability of windowPoSt and further secures the network, has been done in nv19. Since then, the new proof type has been accepted by the protocol. Tomorrow, the second upgrade (nv20) marks the spot when the old proof type will no longer be accepted.
