The bootstrap pipeline works as follows: 1. From a locator, it computes a list of subchains (identified by a Block_locator.step) to fetch. 2. A worker starts to fetch all the headers (top to bottom) from a subchain, starting with the top subchain. 3. A worker starts to download the list of operations by batch of blocks once a batch of headers is available. 4. A worker validates blocks one by one (bottom to top).

These three workers work concurrently.

type t

create ?notify_new_block ~block_header_timeout ~block_operations_timeout validator peer ddb locator initializes a bootstrap_pipeline for a locator sent by peer. It uses the Distributed_db to fetch the data needed and validator to validate blocks one by one with the function Block_validator.validate.

Moreover:

  • notify_new_block is a called everytime a valid block is received.
  • block_header_timeout is the timeout to fetch a block_header.
  • block_operations_timeout is the timeout to fetch a block operation.

If a timeout is triggered, the whole bootstrap_pipeline is canceled.

val cancel : t -> unit Lwt.t

length pipeline returns the number of the headers and blocks fetched
