Usage

• Have node.js and npm installed
  • You can install them from here
• Clone this repository git clone https://github.com/MaxPuig/p2shdata.git
• Install dependencies npm install
• If you want to decode a file in a transaction:
  • Change the txid variable in decode_p2shdata.js
  • Run the file: node decode_p2shdata.js
  • See the file in the data folder
• If you want to encode and publish a file to the blockchain
  • Change all the values between the // EDIT // comments in encode_p2shdata.js
  • First run node encode_p2shdata.js with origin_address_funded = false to get the address you have to fund
  • Run again with origin_address_funded = true to start the encoding process
    • This will first fund all the different addresses. If they get funded and an error occurs, you can run the script again with multiple_addresses_funded = true and it will skip funding all the addresses.
  • Enjoy! You can check the file using the decode_p2shdata.js script
