Crate pallet_subspace

Subspace consensus pallet.

This pallet is in many ways complementary to sc-consensus-subspace.

Pallet maintains crucial state required for Subspace Proof-of-Archival-Storage consensus:

• global randomness
  • based on c-correlation from https://arxiv.org/abs/1910.02218
  • is used to later derive together with time slot a global challenge
• solution range, which is a range of valid solution for Proof-of-Archival-Storage puzzle
  • conceptually similar to work difficulty in Proof-of-Work consensus
  • is updated every Era
• inherents for:
  • storing segment headers and maintaining mapping from segment index to corresponding segment commitment such that validity of piece from solution can be checked later
  • handling of farmer equivocation (together with pallet-offences-subspace) and maintaining list of blocked farmers (effectively burned plots)

Pallet also provides handy API for finding block author, block reward address, randomness and some others.
