(*The "time-to-live" of operations for the next block: any operation whose 'branch' is older than 'ttl' blocks in the past cannot be included in the next block.

(*The level of the last block for which the node might consider an alternate branch. The shell should consider as invalid any branch whose fork point is older (has a lower level) than the given value.

Validation result: the record returned by the protocol on the successful validation of a block.

This is the signature of a Tezos protocol implementation. It has access to the standard library and the Environment module.
val activate : Context.t -> Protocol_hash.t -> Context.t Lwt.t
activate ctxt ph
activates an economic protocol (given by its hash ph
) from the context ctxt
. The resulting context is still a context for the current economic protocol, and the migration is not complete until init
in invoked.
