The first result of a search reveals a bot to automate Raiblock captcha style PoW.

It sounds like Raiblock production/minting/distribution is finalized? How could you measure the Gini coefficient of Raiblocks, how do we know it's not worse especially considering even smaller window of time where people were allowed to participate in the minting and distribution of the supply?

I would take a look at the distribution in the top 10k wallets for Raiblocks versus other crypto to get this data. Mine is anecdotal, but I always take a look at this distribution when investing in a new coin and was surprised to find my small investment was on the list.

I believe they changed the captcha as well during this phase to prevent automation. It was a big source of annoyance for people without time lol.

One person can control many addresses.

If the supply is produced in a limited time frame, then the limited amount of people who had accesses to production will control the supply.
