Nexus quarterly update (q1 & q2 2021)

Welcome to the Nexus 2021 Q2 Quarterly Update. First off, apologies as the 2021 Q1 report was missed due to team changes earlier in the year, hence, this report will cover all the exciting developer, ambassador and community updates for both Q1 and Q2. 

It has been another frantic year in crypto with a variety of hype-cycles emerging to centre stage: DeFi, NFTs, Meme Coins, Interoperability, Energy Usage etc. Though we keep an eye on what’s happening in the broader crypto landscape to identify opportunities (and risks) of interest to Nexus, we also maintain largely focused on the continual development of the Nexus codebase(s) (LLL-TAO, LX-OS, Interface, Mobile) along with the growth of the ecosystem and community.

Let's dive in! This report will cover the following topics:

1. Development Updates
2. Developer Expenditure 
3. Network Metrics
4. Ambassador Updates
5. Ambassador Expenditure 
6. Nexus Virtual Conference
7. Nexus in the Media

1: Development Updates

Team Updates

The Developer team has had a few changes through 2021, starting with Paul Screen announcing in April that he has decided to pursue new opportunities. This ultimately resulted in the closure of the Australian Embassy, and the SigChain keys handed over to the US Embassy (Nexus Development US, LLC and Nexus Ambassadors US, LLC).

During the latest Developer update in June, Colin announced that Victor Moreno, a distinguished engineer at Cisco, is joining the Nexus architectural team providing his networking expertise for the design of the Nexus Protocol. Victor brings with him decades of experience in network engineering and architecture. The hiring of Victor is part of our efforts to build an industry leading team for the design and development of critical network components. We are also in late stage conversations with another experienced developer to help with the LLL-TAO.

@Ajion, a front end developer has also joined the team, and will be supporting Kendal and Krysto with wallet modules, the module store, and future mobile applications. In his own time, he has been working with bubble.io on his digitalityrocks project, and an enterprise use case. Please reach out to him or @mandacam if you have any questions regarding no-code development on bubble. Ajion has also been working on his own project called nexuswars, which he is currently writing a whitepaper for. He plans to use Nexus for points and assets (NFTs), designing it to run on google cloud.

The development team consists of five core working groups, namely:

• LLL-TAO, Colin 
• Desktop Wallet, Kendal 
• Mobile Wallet, Krysto
• LX-OS, Victor 
• Mining, Andrew

Each working group operates autonomously from one another, as cells of people, and forms a strategic board for making internal decisions such as budget allocation between the core working groups. This is our new decentralized social architecture (The Social Stack) in action, providing the capability to scale up to 520 individuals (using 3 layers) without central leadership, or an executive class. It essentially creates multi-layered sub DAO’s to regulate the allocated global contract, through self-organized ‘emergent’ working groups, that check and balance on every layer up the stack, from the bottom to the top. A new open Telegram channel has been created for Developer specific discussions - if you are a developer building on Nexus or would like to find answers for specific technical questions, please join this telegram group.

Core Development Updates

The LLL-TAO developments this year have focused on completing the first Tritium++ update, which provides vastly increased functionality and scalability with at least half of the code. The transition to Tritium++ will involve improvements at both the application layer and consensus layer, with the update being rolled out over two phases, a 5.1.0 API layer upgrade, and a 6.0.0 time-lock activation (block version 9). 5.1.0 is now in testing with a public endpoint available (using branch merging-harden).

Release 5.1.0

API Updates

• Extensive efforts this year have gone into providing major enhancements to the efficiency and scalability of the API coding design, addressing issues such as exponential time algorithms, which was one cause of the Coinkit failure earlier this year. 
• Complete refactor of the entire API layer, providing enhanced functionality and scalability. 
• Addition of the Register API command-set, for managing global registers and performing queries and searches.
• Strict verb/noun semantics, using a templated set of functions to allow the deployment of a new API with only a few hundred lines of code.
• C++ based object-modelling, for managing and creating any type of standard object defined as a noun for the given API. Being dynamic but using static coded data, this is only one step away from dynamically registering object standards for local node’s API.
• Addition of new standard nouns ‘any’ and ‘all’ for wildcard lookup such as finance/get/any or finance/debit/all. These wildcard selector nouns simplify, and allow batching of multiple token contracts in the same transaction.
• Additional command-line argument -safemode, that re-calculates your NextHash before broadcasting the transaction, to protect against hardware faults.
• Additional command-line argument -autotx to generate transactions in the background, so that more complex computation can be done such as more than one -safemode check, along with writing requested contracts to disk for rebroadcast in case of any failure to broadcast the original contracts.

Note, even with safemode enabled, we continue to advise everyone to set a recovery phrase. If you haven't already done so, please go to your wallet, click the hamburger on the user page, and choose “set recovery phrase”. 

• Creation of a templated indexing system that interprets dispatches from the LEDGER layer, providing capabilities to generate PTR records for TNS, Market order indexing, and templated interpretations of nouns in general purpose object API’s (supply, assets, names, etc).
• Comma Separated Values (CSV) interface for nouns and filters, to allow multi-type lookup, such as: finance/list/accounts,tokens. This allows one to use wildcard nouns such as ‘any’ or ‘all’ along with multi-types for aggregated response lists. Filters are used in the same manner: finance/list/accounts/ticker,balance. This would generate a json response (maintaining the JSON hierarchy) that included only the keys ticker and balance. 
• Generic parameter for any transaction generating API command, ‘scheme=falcon’ would allow one to adjust the key type with each new transaction. Whereas previously, to switch to post quantum signatures required you to restart your node.

P2P Market API

• The P2P Market API can be used to sell any digital asset. It has been designed for decentralized marketplaces, that includes assets (NFTs) as one category.
• It currently supports bid, ask, and order standard objects. It is used in such a way: commands/verb/noun or market/create/bid or market/create/ask or market/list/orders etc.
• Also, it supports multi-types and multifilters using CSV such as market/list/bids, which will compound the types. Or multi-filters like market/list/bids/contract, order will return filtered objects containing the keys specified. This functionality is available for all API's like finance/list/accounts, tokens will give you all accounts and tokens, and so forth.
• Unlike DEXs that take an AMM approach, the Nexus P2P Market API will support partial order fulfilment upon the release of 6.0.0. This is made possible with API-level indexing (see Client Mode below) and a partial credit contract (this OP will activate with block version 9).

Client Mode

• This mode underpins the mobile wallet and will also be available for desktop wallets, enabling incredibly fast sync times and minimal storage footprint for those wishing to run a node without staking.
• The final piece being completed for client mode is API-level indexing (currently have implemented market and PTR templates), a major scalability enhancement to the current design. This circumvents having to search the entire SigChain for specific information and instead indexes it locally, saving sometimes thousands of disk lookups (very slow).

Query Domain-Specific Language

• A recursive query language has been developed, enabling direct searchability of the Nexus blockchain, essentially laying the foundations for a decentralized search engine. 
• Combined with the Nexus register-based design, this newly developed query language implementation will allow users to search any metadata stored within an object register i.e. every available data field will become searchable (asset names, token names, and their description fields etc). Functions include filters, queries, recursive field filtering, object filtering, search, sorting, etc.
• This is a highly powerful and unique feature as existing blockchains are only searchable by extracting the stored data and then uploading it into an SQL server.
• When actioning queries, use the results key for now, such as results.balance>10 etc. Asterisk is a wildcard, so doing register/list/names where=results.name=l* will list all names starting with an l. You can do any combination of AND/OR but it's strict with grouping, so to group AND/OR you need (), such as where=(results.balance>10 AND results.ticker=POT) OR (results.balance>100 AND results.ticker=NXS).
• You can also invoke operators for supported commands: finance/list/accounts/balance/sum where=results.ticker=NXS or ledger/list/blocks/tx.contracts.amount/mean would give the average transaction value for last X blocks.
• It also includes statistical operators: sum, mean, array, min, max, sdev, etc. 

6.0.0 Hardfork

Pooled Staking

• This implementation will require augmentation to the core logic and will increase the security of the entire Proof of Stake system while also increasing the availability for regular users. You can find technical details in the July 2020 Quarterly Report. 
• This also includes new additions to the staking protocol to enhance the overall security of the network. All new blocks after version 9 will be required to use this new staking protocol, creating a unified staking system that allows either single block finders, or groups together combining their stake to compete with larger holders. 
• This protocol is enforced on the Ledger Layer, meaning that nobody will have custody or control over your vote, consensus will always be required between nodes pooling together so that it remains decentralized and robust as possible.
• Anybody will be able to become a stake pool, and generally block finders or round leaders will alternate stochastically as the random selection of hash finding will distribute the stake pools and make it difficult for someone to generate influence or control over one another..

LLD Updates

• Major improvements have been made to the custom-built LLD, including the widely anticipated ‘constant time O(1)’ - the ability to maintain the processing speed regardless of the data load. It uses hashmaps, multi-tiered bloom filters, and forward and reverse linear probing that expands its search space in a fibonacci pattern (using the Fibonacci number sequence. This unique design implementation will ensure the Nexus blockchain maintains its long-term scalability trajectory, requiring only a minimum of 3 disk seeks for mostany one key lookups..

Conditional Contract Domain-Specific Language

• Designed for users who will be developing new API’s or contract standards. It enables conditional contracts to be written directly into the API with the use of English, which is a crucial step in realising the full potential of Tritium’s contract functionality. This approach also allows people to be able to read or interpret contracts.
• We thus far have maintained the standard contracts as embedded constants in the codebase. The ability for developers to code new contracts, provides the opportunity for a dynamic standardization using Nexus to manage this state, similar to dynamic object modelling.

Ledger Level Language

• This upgrade will include a programming language for your NextHash and RecoveryHash.
• This will allow competent developers to create contracts for unlocking their sigchain via the next hash (standard credentials) or their recovery hash (recovery phrase).
• This language will support both AND/OR statements and cryptographic operators, to create multiple access patterns for a given sigchain.
• This is a prerequisite to multi-factor authentication between multiple devices, for additional security and as a foundation stone to dedicated hardware that can create 2FA access patterns, along with joint sigchain access schemes.

Crypto API

Our Crypto API helps manage an array of cryptographic functions including public/private key pairs, signatures, data verification, encrypted storage & communications, authentication/authorization, root of trust and more. For example, the root of trust can be used to create certificates (public/private keys) for websites and authentication services without the need for centralized third party Certificate Authorities (CA). These can also be leveraged for document digital signatures, file integrity and even encryption services for data and communications.

Desktop & Mobile Wallet Updates

The Mobile Wallet public beta was released in March and has been positively received by the community. We wanted to produce an intuitive user experience, seamless design, high performance and abstract away any of the complexities usually associated with blockchain and cryptocurrencies - by all accounts and feedback we’ve received, we’re very proud to say that so far we’ve hit the mark on all of these requirements.

The Beta wallet has been downloaded by 822 users (475 Android devices, 347 iOS Devices), providing the team with valuable test logs and feedback, ensuring that we can address any bugs and add commonly requested features before the full release. The full mobile wallet release on both the Apple Store and Play Store is expected shortly after the 5.1.0 update.

The desktop will get update 3.1.0 as part of the Core 5.1.0 update. This update will accumulate more than a year's worth of changes and improvements, including Lite mode and Multi user mode, adding QR codes, new token display system, and a whole host of improvements and bug fixes. A beta version of the 3.1.0 desktop wallet will be available soon.

If you would like to help test the mobile or desktop wallet, please join the following telegram group.

Mining Updates

The mining working group has been recently formed with three main contributors and is being funded by the US Sigchain. The group is currently working on releasing two FPGA miners and an open source hash pool that these miners will plug into, allowing you to start purchasing field programmable GATE arrays to mine the hash channel. 

This group will continue to focus on seeking new ways to improve the mining algorithms and overall mining decentralization. Dedicated funding and bounties towards this working group will help ensure that tactically proficient and competitive miners are being developed.

2: Developer Expenditure 

Below is a roughly rounded table of developer expenditures per working group. We will be providing more detailed expenditure reports in the coming reports and embassy health page. The mining working group costs include the two FPGA miners, as one time fees added to the general hours of the contributors, so expect to see this number lower on the next report.

3: Network Metrics

The data contained in the tables below have been extracted from a full node using the “system/get/metrics” command. 

Registers

The Nexus blockchain utilizes a register-based virtual machine. By inspecting the register metrics, we can gain an understanding of the development activity and ecosystem growth.

Key highlights: the sig_chains and crypto register metrics show a substantial increase in new accounts created on the Nexus blockchain, 8,256 accounts, an increase of 45% since the previous data snapshot in January. The mobile wallet beta is likely a catalyst for this increase as many existing and new community members have been testing out the wallet and setting up accounts. Expect to see continual growth in new accounts when the mobile wallet is fully released.

Another point of interest is the increase in the number of objects, which correlates to the amount of DApp development and community testing, particularly in creating and tokenizing assets (NFTs).

Trust

These metrics provide insights into the active trust (staking) accounts. 

Key highlights: We continue to see the number of active staking accounts increase which is very promising as new participants take part to secure the network and earn rewards. The number of NXS staked has reduced since the last data snapshot in January, however, the percentage of NXS staked is still very healthy at 39.1% which is great to see considering the current market conditions. Once Pooled Staking is released, we expect to see growth in these metrics as all balances, regardless of the size of NXS holdings, will be viable to stake and earn rewards. 

Supply

These metrics provide insights into the NXS supply rates over various time intervals as well as the total circulating supply and inflation rate.

Key highlights: The circulating NXS supply continues to converge towards the target, as the network makes the necessary adjustments in the supply rate. 

Reserves

These metrics provide insights into the amount of NXS currently in the various reserves.

Key highlights: The NXS held in the fee reserve continues to increase in correlation to the network activity and relative fees required to perform certain tasks e.g. token/asset creation.

4: Ambassador Updates

The ambassador group is now about 40 active members contributing across 24 working groups, each of which has a specific focus. Each working group grows with the fibonacci series, or 5 groups of 8, that are formed from 5 groups of 8 groups of 13, or a maximum Ambassador capacity of 520 individuals (similar to the developers).

If there are any disputes in the working group, it is up to the facilitator of the working group to help resolve them. The facilitator is also responsible for driving forward the group, keeping the pinned documents (workflow/task lists) up to date, and organizing meetings when required. The working groups are arranged into 5 operational groups. The facilitator also meets with the other facilitators that form the operational group, when necessary. 

Everyone in the working group are peers, so at the end of the month everyone in the group peer reviews each other's hours and then, if there are no disputes, they submit their invoices for that particular working group to the strategist of the operational group.

Below is the list of current working groups and their respective facilitators.

If you’d like to find out more about the working groups, we invite you to join the community contributor telegram group as the first point of contact, to introduce yourself and let us know where you’d be interested in helping out.

Website

As most community members are aware, Nexus.io has just launched a new website. A significant amount of work has gone into creating a high quality design accompanied by great content and graphics. Massive shoutout to the team that has led this effort: AJKron, Amanda, Bryan Hallmark, Colin, Jules, MrWo, Aeonwise, and Tash.

The new site has been designed to be vastly more intuitive while still retaining the great technical content that has been created over the years. The general layout of the site minimizes the amount of text and uses simple and non-technical language to give a concise overview of all the major building blocks of Nexus. Additionally, an easy to navigate resource hub has been created as a home for technical content that may be more relevant to developers or community members looking for a deeper understanding.

Graphics, Videos & Animations

We have been incredibly lucky to continually see talented and creative people join our community! One area that has greatly benefited from this influx of talent is our graphics and video editing. You would have noticed some of the great and consistent work on the graphics side within our social media presence and articles. Our videos on YouTube have a much more consistent and professional feel to them now, as evident with the truncated videos from the two-day virtual conference. In production is a 3D animation promoting the Nexus Protocol (Decentralized Internet), which will be released shortly, and two storyboards for other explainer animations. 

Translators

The Translators working group is currently focussing on new content that has been created for the revamped Nexus.io launch. The languages being worked on are Chinese, Spanish, Portuguese, Russian, German, Polish, Italian, French, Japanese, Thai, Dutch and Indonesian. 

Content

One of the key focus points this year has been to create content that clearly and concisely articulates the current key value propositions of Nexus as well as its future roadmap. Below is a list of articles that have been created to address this point, we highly recommend reading these if you haven’t already done so!

• Building a Decentralized and Uncensorable Internet, The Nexus Protocol - Simplified overview of the Nexus Protocol whitepaper covering all the major architectural components of the 'New Internet' (microsatellites, ground stations, LX-OS & game theory).
• Nexus, Connecting a Decentralized World - Introduction article to Nexus, current mainnet features, future roadmap, NXS utility, NXS tokenomics and projects building on Nexus.
• NFTs on Nexus - Overview of the history of NFTs, current blockchain solutions and benefits of Nexus when it comes to NFTs/Assets.
• The Complete Beginners Guide to Nexus - Comprehensive guide that will bring you up to speed with everything Nexus! Massive thanks to Paul Luminari for this great piece of content.

Content in the pipeline includes articles on contract engine comparisons, P2P Market, 3DC, NFT use cases, and more. 

PR & Advertising 

Members of this group have been meeting with various PR agencies, and SEO services providers, to find a good fit. We have also been carrying out fresh research into the current popularity of cryptocurrency news platforms to publish the content we have been writing, and to conduct independent reviews of Nexus. 

Biz Dev & Integrations

This group is for the purpose of initiating market research for potential partnerships/platform integrations in an effort to increase developer and user adoption. Members of this group have been researching possible payment processing providers to integrate with, and have been accessing proposed integrations with services such as Zapier and Travalla. 

Exchange Listings

Exchange listings is a hot topic that is constantly raised and discussed within the community as it drives NXS liquidity, awareness and access. We are grateful to be listed on some of the largest and most reputable exchanges such as BINANCE and Bittrex. The daily traded volume has also seen a major uptrend in comparison to 2020, with a 2021 YTD average of $1.2m - note that this excludes two outlier data points in February 2021 which saw volumes exceeding $60m, most likely driven by a coordinated trading group. 

Data Source: Coin Market Cap

This uptrend in volume is possibly largely a symptom of the bull market conditions but it’s also important not to lose perspective of the great efforts that have gone into social engagement, content creation, marketing, DApp development, mobile wallet beta and continued technical development which have also likely contributed to this growth. 

We continue to seek new listing opportunities and appreciate all the suggestions put forward by the community. Most major exchanges have been engaged and listing proposals submitted where possible. One of the most requested exchanges is COINBASE - they currently require an integration to be built for blockchain native coins (such as NXS). Due to the unique design of the Nexus blockchain, this is not a trivial task and would require resources to be diverted away from the main development activities. Also important to note that building the integration does not guarantee a listing, but rather only opens up the opportunity for consideration. Still, we realize the significance of a Coinbase listing and will continue to assess resource allocation for the possibility of building the required integration.

On the occasions where we have received feedback from exchanges we submitted for, we have generally run into a consistent and recurrent major roadblock - listing fees that typically vary anywhere between $10k - $100k+. These figures are attainable for projects that have launched ICOs and bootstrapped their projects with significant funds. Nexus is a community-driven project that was launched without an ICO or pre-mine and hence funds for such activities are limited. The other avenue in which projects are listed is through significant growth in volume and awareness, which drives exchanges to take the initiative in listing a particular coin. This is where we believe we can make an impact - “if you build it, they will come”. 

We have seen over the last year promising growth in both the community and DApp development activities, helping grow our overall ecosystem and awareness within the wider crypto space. We expect this continued growth to drive daily traded volume and open up new listing opportunities as well as additional listing pairs where Nexus is currently listed. 

Community Twitter

Throughout 2021, multiple campaigns were run in an effort to expand the reach of the Nexus Community Twitter Account. The campaigns varied by promoting Nexus Spring Conference tweets, generic technical tweets, and promoting the Twitter account as a whole between February and April. The results are as follows:

Below is a summary of the performance for the community Twitter account over the first 6 months of 2021 - these statistics include the campaign results listed above. April was the best performing month, as promotion for the Nexus Virtual Conference was prominent. 

Additionally, we recently ran a promotional campaign with Swapzone, a crypto swap service provider, by integrating a widget into the Nexus website. Swapzone is currently working on a mini PR about the integration which will be published through their social network channels.

Legal

The legal working group monitors and discusses regulatory movements in the crypto industry that can be seen as potential obstacles for any of the development work Nexus is undertaking. This usually revolves around SEC, FED and Senate Committee hearings as well as studying other crypto case studies that have come under regulatory scrutiny.

Developer Support

We have one of the best communities when it comes to technical support. A huge shoutout to Aeonwise, Neil, Nino, Manda, and Fludflows who are always monitoring the Nexus Support channel and helping troubleshoot any issues experienced by users. Most issues faced usually revolve around setting up wallets, syncing the database, and transitioning from legacy to Tritium. Make sure to join the support channel if you need any assistance, the team is more than happy to help.

5: Ambassador Expenditure 

Below is a table for the expenditure of the Ambassador team for June & July 2021. 

6: Nexus Virtual Conference

Nexus held its first virtual conference in April, a two-day programme filled with exceptional content covering a variety of topics. The theme for the first day focussed on technical subjects such as the ONE stack, quantum resistance and satellite tokenization, while day two showcased multiple DApps being built on Nexus, thought provoking talks and some of the extended functionality that can be achieved with the mobile wallet.

The feedback from the community has been incredibly positive! We will aim to hold this conference format on an annual basis as it gives insights into some of the great work happening on the protocol level and the wider growth in the Nexus ecosystem.

About Nexus

Nexus.io (NXS) is building a new internet driven by a blockchain-based operating system (LX-OS) and routing protocol (Nexus Protocol), creating distributed satellite constellations and ground based content delivery and edge computing. Underpinning the foundation is the Nexus TAO Framework, a seven layer software stack that enables the simplified implementation of smart contracts, Decentralized Applications (DApps), tokens, and Non-Fungible Tokens (NFT’s, i.e. Assets) through a set of extensible Application Programming Interfaces (APIs).

Contracts: Nexus supplies a 64 bit register-based virtual machine as the heart of its smart contract engine. A suite of APIs gives developers access to numerous ready-made contract functionalities. This relieves DApp developers from the burden of learning a smart contract language.

Tokens & Assets (NFT’s): Basic token creation is simple for even non-technical individuals with the Nexus desktop wallet. Arbitrary data can be stored on the Nexus blockchain in the form of assets. Once established, assets can be transferred to other accounts optionally with specified contract conditions (i.e. exchanging NXS / tokens).

Ease of Use: Nexus’ SigChains addresses a primary blockchain limitation — private key management. Users can login to their Nexus wallet with a username, password, & PIN, providing access to all accounts, tokens, and assets. This eliminates the need to backup wallet.dat files and manage private keys.

Database: Unlike most other blockchains that rely on Google’s LevelDB or Oracle’s BerkeleyDB for blockchain storage, Nexus has developed the Lower Level Database (LLD) that outperforms most storage engines by orders of magnitude and remains constant time, meaning it doesn’t slow down as you add more data to it.

Security: The Nexus security model uses many layers of redundancy to provide security to the system. The primary methods include using uniquely generated private keys for every transaction (attack window reduction), and the secondary use of Quantum Resistant (QR) cryptography such as FALCON and SABER.
