Technical Documentation

[julienrbrt]

This repo should contain some documentation about how everything works:

• IBC: explain the two systems, when using sequencer only and when using sequencer + attester network
• Have docs on how to wire extra modules (x/staking, x/distribution and other wrappers)
• Have migration documentation (explain rollkitmngr, and how to migrate from a cometbft chain with a valset to a rollkit chain)
  • Probably should be user story based (as a validator, as a node operator)
  • Add explanation about the rollkit-migrate command and how to run a rpc only comet node if earlier blocks are required (feat(server): add migration command #113 (comment))
• Create a compatibility table between cometbft and abci execution (the table should be almost totally identical, abci exec and rollkit are currently missing websockets and vote extensions)
