Era1 format import/export

As part of our work to reduce disk requirements for running a node (EIP-4444), we added Era1 import/export functionality that allows the import and export of historical data:

  • CLI:
    • -Era.ImportDirectory path/to/dir --Era.From 0 --Era.To 0 --Era.TrustedAccumulatorFile path/to/file
      • From, To, and TrustedAccumulatorFile are optional. Imports everything when the range is set to 0. Trusts the era directory if TrustedAccumulatorFile is not specified.
    • -Era.ExportDirectory path/to/dir --Era.From 0 --Era.To 0
      • From and To are optional. Exports everything when set to 0.
      • accumulators.txt and checksums.txt will be created.
  • RPC endpoints:

    • admin_importHistory and admin_exportHistory: 

      curl localhost:8545 \
-X POST \
-H "Content-Type: application/json" \
--data '{
	"jsonrpc": "2.0",
	"id": 0,
	"method": "admin_importHistory",
	"params": ["/data/era-import", 0, 0, "/data/era-import/accumulators.txt"]
}'
