gitmark

Genesis

Prerequisites

The genesis transaction output starts the chain of marks in git mark

In order to start marking you will need a genesis transaction output aka uxto

This will also have a public address and a private key (secret exponent)

You will need the transaction output id and the private key to start git marking

Storing Secrets

One way to save the secret exponent is in git

git config gitmark.secret <secretexponent>

This is not terribly secure, but for small projects to get started it is convenient. An article on trade offs of this approach is presented here here

A useful way to generate an address and secret exponent would be:

Use a very secure password for anything more than testing

Funding

Once you have an address, send some coins there from a faucet, a friend, or by being marked

The genesis id also doubles as the @id for a gitmark project

Gitmark.json

Optionally a file can be added, gitmark.json, in the root directory of your repo

It may look like this:

{
  "@id": "gitmark:59ff24db0321cb6b32a404815345b00ae68ca8b81150fbea6464ee10557e0fae:1",
  "genesis": "gitmark:59ff24db0321cb6b32a404815345b00ae68ca8b81150fbea6464ee10557e0fae:1",
  "nick": "myrepo",
  "package": "./package.json",
  "pubkey": "7574866ae7653e084c3c8e9e6359660e2c728d249fefb0f984bd32393f2ac67f",
  "repository": "./"
}

• @id is the unspent transaction output
• genesis points to the same transaction output
• nick is a short name e.g. as used in npm
• package points to a package.json info
• pubkey is the pubkey for the genesis tx, in hex
• repository is an absolute or relative hint as to where to find the git code

First git mark

Once you have your genesis tx, you can make your first git mark by running, for example:

git mark --genesis b1fb9acb83f85887760b2e1a71e1df370976b1596be101bb0dbe8fd1c80f91cd:0

Do this after you have committed your first files, and as recommended a gitmark.json file too

Notes on Commits

The commit requires a name, email and commit message, with optional signing.

The name can be whatever you want

The email is open, but you can select a noreply address to indicate privacy, such as noreply@.gitmark

The commit message can be anything, and will be the first commit ready to be marked. e.g. “first”

Notes on .gitmark

The .gitmark address is just a place holder if it is undesirable to enter a public email address. In future it may be possible to resolve .gitmark URLs to a working GitHub repository and deployments
