go-merkle

create a merkle tree with GO lang to be used with solidity

this is not useful itself since i used and built it for a specific purpose in a project, but it can be useful as a reference for creating merkle trees in go

scripts

convert_int_string.js - convert all the numbers in json to strings
checkHash.js - check the hash of the merkle tree if is the same in JS(and solidity)
sampleCOntract.sol - solidity contract to create the nodes and check the hash
merkle.go - create the merkle tree and save it to a json file

merkle.go take a json file like

[
  {
    "int_it": "631359070595067400",
    "renting": "3"
  },
  {
    "int_it": "631507570671499300",
    "renting": "5"
  },
  {
    "int_it": "630950076210238000",
    "renting": "5"
  },
  {
    "int_it": "631254397440568800",
    "renting": "3"
  },
  {
    "int_it": "633917065299962900",
    "renting": "1"
  }
]

and create a json file like

  "root": "0x3097752e39f8dfa07e1715d4876d4e8439e2a26332f8cd19060b3a7f3029d038",
