Updated Descriptions:

--read-mode arg (=speculative)

• Database read mode ("speculative", "head", "read-only", "irreversible").
  In "speculative" mode: database
  contains state changes by transactions
  in the blockchain up to the head block
  as well as some transactions not yet
  included in the blockchain.

• In "head" mode: database contains state
  changes by only transactions in the
  blockchain up to the head block;
  transactions received by the node are
  relayed if valid.

• In "read-only" mode: (DEPRECATED: see
  p2p-accept-transactions &
  api-accept-transactions) database
  contains state changes by only
  transactions in the blockchain up to
  the head block; transactions received
  via the P2P network are not relayed and
  transactions cannot be pushed via the
  chain API.

• In "irreversible" mode: database
  contains state changes by only
  transactions in the blockchain up to
  the last irreversible block;
  transactions received via the P2P
  network are not relayed and
  transactions cannot be pushed via the chain API.

New Options:

--p2p-accept-transactions arg (=1) Allow transactions received over p2p
network to be evaluated and relayed if valid.
--api-accept-transactions arg (=1) Allow API transactions to be evaluated
and relayed if valid.
