Roadmap

Short Term: QDEX - Standardized price indices published via web end and over coin network
Mid Term: QUINN - Quotient Intelligent Neural Network built on the Sapient AIFX Blockchain Singularity
Long Term: XQNFX - Algorithmic trading tools in-wallet backed by QUINN, with script editor and script trading

Introduction
Quotient Digital Financial Network is a high interest rate proof-of-stake decentralized crypto currency network. Our total coins to be mined via proof-of-work mining is taken from the golden ratio, an interesting number that some believe humans naturally seek out.

Quotient offers a 1,618% annual interest rate, with a 618 coin cap on the stake reward per block. The reward cap encourages breaking unspent outputs into smaller units for a better distribution of coin weight and smoothing the effects of large wallets coming on and off of the network.

Quotient is released with two core purposes:

1. Provide a platform for evaluating the code optimizations we have implemented, particularly as regards maps and iteration.
2. Build features external to the wallet that bridge to the web and promote awareness and interest.

Technical Innovation
As per our first purpose, the Quotient codebase has a number of implemented code optimizations intended to improve the overall performance of the wallet and daemon. Proof of Stake currencies in general tend to have periods of intense resource usage as there are many points of iteration through the blockchain, transactions, wallet transactions, and other internal objects. We have made a number of tweaks to the types of data structures used to store this information and the iteration process, to try to achieve less resource usage and speed up the processes.

These changes are relatively straightforward in swapping out some of the "std::map" standard map data structures for Boost unordered_map and flat_map structures, and updating some of the iteration mechanisms to use BOOST_FOREACH macros instead of for loops. It is nearly impossible to benchmark these kinds of optimizations in a normal environment with any sort of accuracy...and crypto currencies give us the perfect platform to try things and see how they perform in the real world.

Why even bother messing around with data structure optimizations in the coin codebase? Anyone who has operated a pool or an exchange knows that proof of stake wallets tend to slow down and consume resources as the transaction volume increases. Its worth a shot to see if going to unordered maps in particular can help pull some of that utilization down.

We have also implemented different hashing algorithms for proof-of-work and proof-of-stake. For Proof of Work we have the tried and true Scrypt algorithm, and for Proof of Stake we have the Blake 256 algorithm. Blake-256 is a superfast hashing algorithm that makes a lot of sense for efficient stake mining by individuals, but Blake-256 has not yet achieved widespread use among miners (MiningRigRentals offers Blake-256 for instance, but generally only has a handful of available units to rent). So as a compromise we went with Scrypt for the PoW mining portion because it is cheap to rent and a lot of enthusiasts have Scrypt mining hardware sitting around. It is important in our view to use a PoW algorithm that brings in the most miners as miners are what determine the community in a coin.

We moved the RPC console to a console tab, as having to go to the pop-up window is annoying. We also added a clear command, so you can either type "clear" or press Ctrl-L to clear the console.

Our planned future innovations tie into our 2nd core purpose, which involves extending the P2P protocol and RPC interface to support flowing certain data from the coin network to the web and vice versa. We will release more information on what this entails in the coming days. Its a pretty simple and straightforward but extremely useful thing, but we don't want to give away the idea just yet until we are ready.

Quotient Financial Network Stands on its Own
Quotient was designed to stand on its own as an intrinsically valuable coin in its own right, regardless of various future developments. The high PoS interest rate and design of the coin is such that it provides a nice portfolio addition and complement to other crypto currencies that have stood the test of time over the past year or two.

Specifications
1,618,033 coins (proof-of-work)
1,618% PoS interest rate
618 coin cap on stake reward
61 second block spacing
161 blocks to maturity
Min Coin Age 16 hours
1% Premine (16,180 coins) - so the developers are well fed

Block Reward Schedule

0-500 618
501-1000 309
1001-6000 154
6001-6500 309
6500-6843 618

P2P Ports: Mainnet: 30994, Testnet: 30993
RPC Port: Mainnet: 30997, Testnet: 30996

Hardfork at block 74000 - Max stake reward cap going from 618 coins to 16.18 coins. Note that this does NOT change the overall amount of stake you can earn, but will increase competition on the network.
