there's been 120eth worth of deposits between blocks 100 and 200 but only 100 with referral

count referrals (100,200) will output

0xb8baa0e4287890a5f79863ab62b7f175cecbd433  80eth   80%
0x2cffa6e8b85028952be77c0ae2c2c319499c6eff  20eth   20%

total                                       100eth  100%

Neither caller address nor EOA who sent the transaction doesn't matter for referrals

Contract

add referral's address to existing method submit as optional argument
https://github.com/depools/depool-dao/blob/274f7b857d37399501c1c08aa92ddf1de3fd9a0b/apps/depool/contracts/DePool.sol#L96
submit(uint256 referral) payable
If referral missing, it would be called by the client with 0x00 value (zero cost)

the event Submitted should include referral address (0x00 if not set)
https://github.com/depools/depool-dao/blob/274f7b857d37399501c1c08aa92ddf1de3fd9a0b/apps/depool/contracts/DePool.sol#L488
emit Submitted(_sender, _value, _referral);

Scanner

pure python3 stateless script running from CLI with block range passed via ARGV
python3 count_referrals.py <start block> <end block>
The algorithm:

1. connects to given web3 endpoint
2. polls the blocks by number (sequentially, synchronously, incrementally)
3. filters receipts with destination (DEPOOL_CONTRACT) AND event Submitted
4. parse event fields, group by referrals and summarize deposited amounts
5. calculate the referral percentages
5. print the result to stdout
