Genesis transaction storage
Genesis storage is zip archive file containing raw genesis transaction and other referenced data. This is used for delivery genesis data.

Entries in the archive

Genesis transaction

File name is fixed, genesis.json. For detailed information, please refer Genesis Transaction.

Genesis data

Data referenced by the genesis transaction should be stored as genesis data. File name is hex-decimal representation of sha3-256 hash value of the data. So, it should be 64 lower case hex decimal characters.

Genesis template

Introduction

It's hard to make genesis transaction with hash values of other genesis data, and also include them for genesis data. Genesis transaction including followed directives is called as genesis template.
Some utilities accept genesis template for genesis storage.

Directives

You may use following directives in values of genesis transaction.
::: v-pre
  • {{hash:<file>}} It will be replaced with hex decimals of hash value of specified file. And the file will be included into the storage automatically.
    Example
    1
    "hash:{{hash:governance.zip}}"
    Copied!
    1
    "hash:0x810b7af78caf4bc70a660f0df51e42baf91d4de5b2328de0e83dfc56fd70a6cb"
    Copied!
  • {{read:<file>}} It will be replaced with hex decimals of file content itself. It's designated to use in content tag.
    Example
    1
    "{{read:governance.zip}}"
    Copied!
    1
    "0xaabbccdd...."
    Copied!
  • {{ziphash:<dir>}} It's very similar to {{hash:<file>}} except that it accepts a directory for input and makes a zip archive before storing and hashing.
  • {{zip:<dir>}} It's very similar to {{read:<file>}} except that it accepts a directory for input and makes a zip archive for reading. :::
You may use template in values of genesis transaction. You may use this scheme for making genesis storage from genesis transaction while it includes other genesis data.
Note: If you refer same directory in different positions, it may returns different hash value or bytes.
