reth stage unwind

Unwinds a certain block range, deleting it from the database

$ reth stage unwind --help
Usage: reth stage unwind [OPTIONS] <COMMAND>

Commands:
  to-block    Unwinds the database from the latest block, until the given block number or hash has been reached, that block is not included
  num-blocks  Unwinds the database from the latest block, until the given number of blocks have been reached
  help        Print this message or the help of the given subcommand(s)

Options:
      --instance <INSTANCE>
          Add a new instance of a node.

          Configures the ports of the node to avoid conflicts with the defaults. This is useful for running multiple nodes on the same machine.

          Max number of instances is 200. It is chosen in a way so that it's not possible to have port numbers that conflict with each other.

          Changes to the following port numbers: - `DISCOVERY_PORT`: default + `instance` - 1 - `AUTH_PORT`: default + `instance` * 100 - 100 - `HTTP_RPC_PORT`: default - `instance` + 1 - `WS_RPC_PORT`: default + `instance` * 2 - 2

          [default: 1]

          [default: 2097152]

      --pooled-tx-pack-soft-limit <BYTES>
          Experimental, for usage in research. Sets the max accumulated byte size of transactions to
          request in one request.

          Since `RLPx` protocol version 68, the byte size of a transaction is shared as metadata in a
          transaction announcement (see `RLPx` specs). This allows a node to request a specific size
          response.

          By default, nodes request only 128 KiB worth of transactions, but should a peer request
          more, up to 2 MiB, a node will answer with more than 128 KiB.

          Default is 128 KiB.
