Banano For Your Information - Store data in Banano addresses.

Goal

To store data in wallets, link it to a block (e.g. a send block), automatically detect and parse the data.

At the moment you can only encode and decode data in Banano addresses.

Limitations

The upper limit for storage is 8216 bytes for the data encoded in msgpack. An 8216 byte msgpack would be encoded in 257 addresses.

Examples of encoding data in addresses

Encode short data

Encoding data that take up less than 25 bytes will only take up a single address.

const bnfyi = require('bnfyi');

const shortData = { note: "wen poem bread" };
const shortDataInAddresses = bnfyi.encodeInAddresses(shortData);

The resulting value of shortDataInAddresses from the example above will be:

[ 'ban_1foryourinfoi8k8wuunepq9gsdg63r8ysdf63j96sd3ei1111117dfm1e5s' ]

To decode shortDataInAddresses again:

const decodedShortData = bnfyi.decodeFromAddresses(shortDataInAddresses));

The resulting value of decodedShortData will be the same as shortData.

Encode longer data

const longData = {
  note: "Lament of Anemone\n" + 
        "After seeing what there is to see\n" +
        "After reposting every meme\n" +
        "\n" +
        "Everything is the same\n" +
        "Predictable\n" +
        "\n" +
        "Going into the routine\n" +
        "Minion quarantine\n" +
        "\n" +
        "Omniscient sonder of Anemone"
};
const longDataInAddresses = bnfyi.encodeInAddresses(longData);

The resulting value of longDataInAddresses from the example above will be:

[
  'ban_3foryourinfo1p1taumhgjkxmgkee7ppcumn63qpea43fskptuug4ghq4mah',
  'ban_1saca7m9asdk63spcsdbfsmk1xuae7t41x5aeos8ca5bgei9aus1wrwae8uf',
  'ban_1wu7en764smneos41wm7g3qq8x5bfsmk1sdpeos9ka5feoppc4icmdicu91s',
  'ban_1jdpeos9kx5af7q8ga5bgei9at5763sp4ud73ba96sd6f7jqard4jdgsoj5f',
  'ban_1u573a76guubfsmk1tdggjqk1x5aeni96uuogjnpwsacbonpwtdh79im6pnk',
  'ban_1uj1g7tp4wm3fst8kum73a76yudgf7sp8td7fst41wuhfsk8cwj18uggrztf',
  'ban_1uu8631pwsdffxq8c11111111111111111111111111111111111i35yqo7f'
]

To decode longDataInAddresses again:

const decodedLongData = bnfyi.decodeFromAddresses(longDataInAddresses);

The resulting value of decodedLongData from the example above will be the same as the value of longData.
