Modular Wallet

It is done extending bitcoin original wallet, by means of an extension of wallet source. So, extending original wallet (wallet.dat), it is possible to storing gem creation information into extended wallet (gemwallet.dat).

WARNING:  If you delete or lose your gemwallet.dat file you will lose your gems. Always backup your wallets.

2) Sending gems. 2) Sending gems. Bitgeminization is symbolized {DMD, RBY, SPR, EMD} -> BTG. It is the opposite of gem creation, and it is carried out when an incoming BitGem transaction is converted to existing gems.

The aim of current development is to provide a native method for sending colored gems, ie. DMD, RBY, SPH, EMD.
Gem creation and Bitgeminization (sending gems) processes are being developed and refined for a future wallet.

Lets you transform your BTGs into the different type of gemstones, diamond, ruby, sapphire, emerald. 4Cs model take the 4 gemstone properties: Carat, Clarity, Color and Cut and modifies your gems using those parameters.


A carat is a weight unit and is equal to 0.2 grams. Usually, there is an exponential relation of value with carats.


Is a graded scale, from ‘D’ to ‘Z’, with D being the best grade and Z the worst.

In diamonds, colorless is better and perfectly colorless would be D.

In rubies, sapphires and emeralds, more defined hue colors are more valued, and more intense colors (saturated) are more valued too. Well defined, intense, brilliant  colors are graded from D (best) to Z.


Clarity refers to the lack of inclusions or flaws in a gem. The Clarity Scale contains 11 grades,

FL: Flawless  – No inclusions or blemishes are visible to a skilled grader using 10× magnification
IF: Internally Flawless – No inclusions and only blemishes are visible to a skilled grader using 10× magnification
VVS1, VVS2: Very, Very Slightly Included – Inclusions are difficult for a skilled grader to see under 10× magnification
VS1,  VS2:  Very Slightly Included () – Inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnification
SI1, SI2:  – Inclusions are noticeable to a skilled grader under 10x magnification
I1, I2, and I3 – Inclusions are obvious under 10× magnification and may affect transparency and brilliance


Cut refers to the symmetry, finish, style and proportion of cut. Just graded as EXCELLENT, VERY_GOOD, GOOD, FAIR, POOR.

While round shapes are generally more valued, shape preference is a a personal choice.

Shapes included are :

Development process

Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.

The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if they don't match the project's coding conventions (see coding.txt) or are controversial.

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are regularly created to indicate new official, stable release versions of NovaCoin.

Feature branches are created when there are major new features being worked on by several people.

From time to time a pull request will become outdated. If this occurs, and the pull is no longer automatically mergeable; a comment on the pull will be used to issue a warning of closure. The pull will be closed 15 days after the warning if action is not taken by the author. Pull requests closed in this manner will have their corresponding issue labeled 'stagnant'.

Issues with no commits will be given a similar warning, and closed after 15 days from their last activity. Issues closed in this manner will be labeled 'stale'.
