A decentralized and distributed sharing network based on Nano and IPFS

• PoC version: A interface for converting IPFS hashes to Nano wallets and vice-versa.

Install all modules and run the test script

npm i
npm test

If all went well, the return of the test script should be this:

So, start the node (port 3000 by default):

npm start

"nano_" + base32 (pubKey) + base32 (blake2b (pubKey))

This means that the opposite process brings your 32-byte public key back.

One way to know which wallet has a message behind it would be by sending specific values, as if they were "flags". Nano supports up to 30 decimal places and there are no fees, so it can be done extremely cheaply. (I will show the incredible potential of these "flags" in the future)

IPFS hashes

A common IPFS hash, such as this one, consists of 2 specific identifying bytes at its beginning (0x12, 0x20) + checksum sha256 from file (32bytes), converted to base58.

hex-to-base58 (0x12 + 0x20 + hex (SHA256 (file)))

That is, the information that really matters to us, the sha256 checksum of the file, is exactly 32 bytes, so after separating it from the IPFS hash, we can convert it to Nano wallet format. Using it in place of the public key and marking the transaction with a specific Nano value (flag). To convert back to hash, just do the reverse process.

First resolve the dependencies (git, npm and nodeJS)

  sudo apt update && sudo apt upgrade

  sudo apt install curl python-software-properties

  curl -sL https://deb.nodesource.com/setup_12.x | sudo -and bash-

  sudo apt install nodejs

  sudo apt install git

To verify the installed versions:

node -v
npm -v
git --version

Download this git project and install all modules listed as dependencies in package.json

git clone https://github.com/anarkrypto/nano-file-system.git

cd nano-file-system

npm install

Run the test script:

npm test

Output:

Qmdhk33FBzu91dnxR5VeMqhpysEXMzjCbPUqCvX6LkJeuM -----> xrb_3s48ir3zow4zhpxw7abo64fdzyhpcphprajpqwnrhf8p71n6gi6arfaa4ms5

Start the node server locally, (port 3000 by default):

npm start

Output:

Server listening on https://localhost:3000

So you can open this address in your browser.

This is a interface for converting IPFS hashes to Nano wallets and vice-versa. For now only a Proof of Concept. But this project will soon become the basis for a decentralized and distributed sharing network. Wait...
