# Tool to download chain history data from local node, and save it to the json
|
|
# file or sqlite database.
|
|
# In case of json:
|
|
# Block data is stored as it gets transmitted over the wire and as defined here:
|
|
# https://github.com/ethereum/portal-network-specs/blob/master/history-network.md#content-keys-and-values
|
|
#
|
|
# Json file has following format:
|
|
# {
|
|
# "hexEncodedBlockHash: {
|
|
# "header": "the rlp encoded block header as a hex string"
|
|
# "body": "the SSZ encoded container of transactions and uncles as a hex string"
|
|
# "receipts: "The SSZ encoded list of the receipts as a hex string"
|
|
# "number": "block number"
|
|
# },
|
|
# ...,
|
|
# ...,
|
|
# }
|
|
# In case of sqlite:
|
|
# Data is saved in a format friendly to history network i.e one table with 3
|
|
# columns: contentid, contentkey, content.
|
|
# Such format enables queries to quickly find content in range of some node
|
|
# which makes it possible to offer content to nodes in bulk.
|
|
#
|
|
# When using geth as client to download receipts from, be aware that you will
|
|
# have to set the number of blocks to maintain the transaction index for to
|
|
# unlimited if you want access to all transactions/receipts.
|
|
# e.g: `./build/bin/geth --ws --txlookuplimit=0`
