nex·usˈneksəs' : a connection or series of connections linking two or more things.
Nexus will provide the framework to enhance the freedom, self-sufficiency, and creativity of everyone in the world. A fully decentralized global network will allow people to transfer value, data and services to one another in a truly peer-to-peer fashion. A digital currency called Nexus (based on Satoshi Nakamoto’s Bitcoin) has been created to facilitate this system. However, no system which relied on traditional ground based telecommunications networks is truly decentralized. For this we look to the stars. The Nexus blockchain will be secured in space. Cube satellites in low earth orbit will provide network access worldwide at acceptable latencies. Coupled with hardware devices on the ground, a global decentralized mesh network will be born. People will launch new peer-to-peer services on the network without the approval from a centralized authority. This network must be built on a strong foundation. Over the past two years, many security enhancements and innovations have been developed and proven on the Nexus blockchain. These include 571-bit privacy keys for increased quantum attack resistance, multiple mining/staking channels, dynamic difficulty adjustment, 1024 bit SHA3 based block hashes, unified time, trust keys, and more. Nexus is more than technology. Nexus is the connection of people, economies, philosophies, ideas, computers and resources that will free mankind. Welcome to Nexus!

THE HISTORY OF NEXUS
Nexus has gone through some changes over the past couple of years in terms of the focus of the Project. Nexus started as a Vision of improving upon some features or lack thereof in the Bitcoin protocol and at the same time ridding the crypto-sphere of scam coins. Lead Developer Videlicet (Viz) saw an opportunity to study the roots of the Bitcoin core code and understand how Satoshi structured Bitcoin and identified opportunities for improvement. At the same time, the altcoin market was being flooded with scams and pump and dump schemes where coins with various promises, buzz words, and the allure of quick profits were used to swindle BTC from communities which were then abandoned by the coin cloner developers. From that Vision was born Coinshield (CSD).
The first CSD block was mined on September 23, 2014 and the Project, soon to be named Nexus, was live. At that point the Project had 2 channels of minting, a Prime channel (CPU) and a Hashing (GPU) channel. The blocks included a first ever subsidy where a portion from each mined block would be sent to one of 13 developer accounts and another potion would be sent to one of 13 Exchange accounts. On January 24, 2015, CSD was listed on Bittrex Exchange. Shortly afterwards Viz drafted a White Paper that outlined how the Network would work to recycle and merge the economies and communities of these pumped and dumped coins. The goal was to help the folks in those communities, bring them into the CSD Community, and at the same time help clean up the crypto sphere. The exchange accounts would be used to merge these economies by exchanging the coins for a portion of CSD.
On April 11, 2015 Viz announced the intention to rebrand to Nexus. Discussion pursued about the ticker symbol and NIRO was chosen to represent Nexus. On July 24, 2015, Nexus Version 2.0 was released with Nexus Proof of State (nPOS) and the introduction of the Trust Network. This laid the Foundation for the broader scope of Nexus. At the beginning of September 2015, Videlicet revealed his identity as Colin Cantrell. In October 2015 a more formal Team was formed to increase development, build the community, and market Nexus. A core focus was also to discuss the direction of Nexus. Throughout those discussions, the decision was made to abandon the recycling and merging that was part of the Coinshield Project. The technical ability was there to implement the merging, but with the growth and explosion in the number of new cryptos, the process would be in vain and would have little impact. Therefore, Nexus began to develop into something much, much more and went a different direction.
Nexus still seeks to help carry on Satoshi’s dream of Decentralization and as such continues to work on improving the Bitcoin Protocol by using the Nexus Network as a testing ground for these improvements. Some of how it works, goals, specifications, and features are described further in this post. For a full understanding of the evolution of Nexus, read through the thread.
HOW IT WORKS
Nexus is a decentralized, worldwide network distributed through three channels of security to allow for fast, secure, and decentralized transactions.
Consensus in Nexus is not limited to the vote being given to block producers or even interest based nodes. Nexus has layers of the network that check and balance each other to prevent one layer from becoming too powerful and inhibiting the security of the network. Nexus channels include Prime Channel (CPU Mining), Hashing Channel (GPU Mining), and Nexus Proof of Stake (nPOS).
The reputation of Nodes (computers in the Peer-to-Peer Network) and corresponding Trust Keys (addresses that receive interest payments) is established by their honest contributions of Time, Weight, and Trust on the network. These Trust Keys become very valuable as it takes a great deal of effort to build Trust. Currently the interest rate is a variable rate that increases from 0.5% to 3% within one year the longer you build Trust on the Network.
Nexus has checks and balances in consensus so that the control of the network is more distributed providing greater security and network stability. Coupled with Quantum Computer resistant Private Keys with 571 bit encryption (much more secure than Bitcoin), Trust Keys and reputation; Nexus serves the WORLD as the most secure cryptocurrency to date.
Currently in development is a new data structure that allows the scaling of a blockchain network to better compete with and eventually replace current financial transaction systems. This new data architecture will allow the Nexus Network to grow and adapt to process increasing numbers of transactions as capacity is required by the network. Currently the Nexus network can process 5,000 transactions per second.
Nexus is actively building relationships within the aerospace industry to allow for the hardware infrastructure to be compatible with its transaction system. Nexus is building the foundation to broadcast the blockchain and Nexus Network from space. Under existing hardware infrastructure, cryptocurrency is technically under the mercy of telecommunication and government technology industries. Coupled with both the development of software and hardware, Nexus seeks to free men from centralized financial institutions.

Maximum Annual Inflation
nPOS: Up to 3% annually; 2% after initial distribution is complete
Prime and Hashing Minting Channels: 1% annually after initial distribution is complete
300 seconds for Hashing minting channel and 300 seconds for Prime minting Channel for an average of 150 seconds
60 seconds for nPOS
Prime and Hashing Minting Channels: The effective reward is established by the reserve balances. These reserves have a decayed amount deposited every time interval of one minute. If the balance is below a given threshold, the reward value will be based on a time’s value of a decayed amount. This means that the reward will be given based on how long it was taken to create the block. This prevents the reserves from being depleted as large amounts of computing power jump on and off the mining network.
nPOS Minting Channel: The effective reward is an annual interest rate that ranges between 0.5 and 3.0% annually.
The miner’s difficulty is calculated by a proportion generated from the time it took to create the block, and the target time. The target time is calculated by the NXS Reserves working to deflate the difficulty if the reserves go over a threshold. This is designed to maintain transaction processing in the loss of computing power to given channel, by aiding in the reduction of the difficulty to a more suited level.

HOW NEXUS IMPROVES UPON THE BITCOIN PROTOCOL
Each channel reinforces each other to prevent 51% attacks on one channel forcing attacker across multiple channels.Hashing:
SK-1024, SK-576, SK-512, and SK-256 used in all hashing. Pure SHA3 using Skein and Keccak.SK-1024:
Using Skein-1024 and Keccak-1600 for GPU PoW to produce a 1024 bit output hash used for the block hash providing the highest security. Prime:
Searching for Dense Prime Clusters as CPU PoW, finding these clusters of numbers that are ~308 digits to verify prime density in large numbers.Keys:
571 Bit Private Keys compared to 256 bit in other currencies. Using NID_sect571r1 as the algorithm.Difficulty:
Calculated with time overlaps and true % over bounds, using weighted block average over past 5 blocks.LLP:
Lower Level Protocol as a template protocol to allow any protocol to be created with ease without need for repeated network programming.Core LLP:
Protocol responsible for time keeping as an advancement to NTP, keeping clocks on the network synchronized within a few seconds of one another. Maximum clock drift for Nexus is 10 seconds.Mining LLP:
Dedicated Mining Protocol outside of JSON-RPC Server to allow the greatest performance for mining. Protocol can handle 5k + connections allowing solo mining of any magnitude.No Reward Halving:
Rewards are calculated along an exponential decay curve to slowly reduce the value of each block rather than shock both miners and the market with block reward halving which acts as a rudimentary decay model.Released Reserves:
Decayed Amounts are deposited into the Reserves for each channel, preventing a miner from being able to mint more than the projected amount while difficulty is compensating to their amount of computing power.Fractional Rewards:
When reserves are below given thresholds, the mining reward is then based off of the time it took to create a block preventing a miner from ever being able to deplete the reserves.Decentralized Checkpoints:
All blocks must root from the most recent checkpoint which is declared by fitting into a timespan. This allows checkpoints to be automatically created every hour, without the need for any master node or checkpoint broadcast.Trust Keys:
Interest rate is increased the more a node services the main chain giving incentive to active stakers. This also increases the cost of an attack for in order to attack with a trust key it requires time to get it to the same threshold.Nexus Proof of Stake:
Proof of Stake system based on the Peercoin protocol heavily recoded from the ground up utilizing energy efficiency threshold, trust keys, and logarithmic weights to create the fairest and most stable Proof of Stake system to date.Developer Commission:
Built into the protocol levels, gives a small decayed amount to developer addresses every block [~1 NXS] over 10 years amounting to a total of ~2.5% after 10 years, and starting at ~1.5% as a way to bring the benefits of pre-mines, without the risk to investors. This means developer account has no control over the currency as it will never be of a high enough %, but it allows funds to be distributed to development removing need for corruptible foundations such as the Bitcoin Foundation which was spawned to cover developmental costs.
PLANNED FUTURE FEATURES
Reversible Transactions: Transaction can be reversed if below expiration time by sending transaction void to the network.
Two-Way Signatures: Receiver of transaction will be required to sign to prove ownership of txout before it will be processed. This will prevent burning coins by accident.
Trust Network: Using Trust Keys and more sophistication in Checkpoints will create a Trust Network in which nodes will be given the opportunity to vote on checkpoints and blocks to agree on set blockchain. This will prevent a rogue node from trying to manipulate the network.
Sync-less Wallets: Using the Trust Network as a backbone and the LLP for the protocol, will allow wallets to remain sync-less by processing transactions in the Trust Network.
HTML5 Wallet: Probably coming sooner rather then later, essentially building up a clean simple HTML5 wallet using qt web server. Will have all the great visuals that HTML5/CSS3 provides. Most likely coming before transaction features to have a cleaner GUI to integrate more functionality into.
Double Spend Protection: Using input locking and checking on reorganizations, can prevent a transaction from ever being able to be overwritten by a longer blockchain after a checkpoint eliminating any threat of 51% attacks.
LLL Integration: Once the Library including Static and Dynamic Databases is finished, next will be integrating LLP, LLD, and LLS with possible LLE for encrypted communications and high efficiencies in protocol responses and data storage.
UPDATES TO BE INCLUDED IN FUTURE RELEASESUpdates Planned for the Full 0.3.0 Release include:
1. LLD database integration.
2. Trust Key Depreciation Update
3. Many new RPC commands for increased utility and Block Explorer performance.
4. LLP Updates.
5. Reworking of the nPOS system for increased difficulty.
