Ethereum Address Finder

Made with Go compiler v1.10.1

Simplistic script to rip through the blockchain and fetch all addresses that are a party in a transaction in a range of blocks. Requests are parallelized to speed things up. Unfortunately there is a hardcoded file descriptor limit in Geth nodes at 2048 so I limited it to sending 500 requests at once. (Can probably find a number to get closer to that limit, I kept it lower so that network activity wouldn't make the script fail).

Runs at a little over 30 blocks per second on machine with 16GB RAM and 6 CPUs.

Usage

• You must have an Ethereum node running locally on port 8545. You can try connecting to infura or some other hosted node but performance will likely suffer and they probably won't be happy with you spamming requests at them.

go get github.com/satello/eth-address-finder
go install
./eth-address-finder -start=<start_block> -end=<end_block> > output_file.txt

At the moment it just prints all addresses to STDOUT after it finishes so I just pipe the results into a file.
