Banano-Faucet VS bananopy

Prussia's faucet is a good base.

if you are interested in giving away ban you might want to checkout prussias faucet :)

https://github.com/jetstream0/Banano-Faucet Prussia makes a mean banano faucet you can fork (Js/HTML type deal)

If you're a programmer: It's pretty simple to access all the blockchain events(Usually). You can pretty much find tipbot, faucet, block-explorer, etc. codes on Github to see how to get the info for that blockchain or coin. Python would work for the task(if you can find docs or code in python for the blockchain you need). I don't know about the getting past prices part, I've only done enough with banano python to retrieve blockchain info. For example: Banano code includes API(s), tipbots, and faucets(Probably half or more of the faucets are made by Prussia!)

And in some client/node libraries (example), you can find this unit:

To actually give out the banano, you use your private key to sign a send block (which contains information of your account, your new amount and the destination and some other info). You can take a look at an example JSON request here. You would send a standard POST request to a node. GoBanano provided the sufficient framework for creating the blocks and balances but didn't have a wrapper for the RPC calls. Libraries such as bananojs or bananopy provide wrappers and are easier to setup/use. prussia dev's opensource banano faucet also contains a lot of the logic you may need to setup a faucet. Hope this helps!

There's nothing stopping the community from arbitrarily defining 19 decimal places as a new unit. There is already one such arbitrary unit, banoshi, which has 27 instead of the full 29 decimal places.
