SegWit Status Update

Over the past month development has been progressing to bring SegWit (Segregated Witness) support to the Stratis blockchain, resulting in upgrades to the consensus, mempool and wallet features.
SegWit is an update to the transaction scripting layer that, among other things, increases the effective maximum transaction throughput.
The latest milestone to be achieved is the successful sending of SegWit transactions on the Stratis TestNet. You can find more detail below regarding the SegWit transactions in question, shown in an experimental version of the Stratis Core wallet:

Transaction 1

Transaction 2

Transaction 1 shown above, spends a legacy P2PKH (i.e. pay-to-pubkey-hash) input, and sends it to a native SegWit P2WPKH bech32 address (i.e. pay-to-witness-pubkey-hash).

Transaction 2 spends a native SegWit input, sending it to a SegWit address. This is therefore a fully native SegWit transaction with no legacy inputs or outputs.

These are the first encouraging steps to bringing SegWit support to the Stratis Mainchain, further development will continue, focusing on bringing SegWit support to our wallet implementations. The SegWit implementation will then undergo our full end-to-end testing procedure within our Stratis Coherence environment.

Cirrus Core – Community Testing & Giveaway

We are excited to announce an updated version of Cirrus Core that is now available for community testing.
This updated version of Cirrus Core allows users to simply manage tokens issued on the Cirrus Sidechain and also create their own SRC-20 token with a single-click. This functionality removes any historic complexities that are associated with issuing a token via a Smart Contract and allows individuals/businesses to effortlessly deploy their own token on a Stratis sidechain for immediate use.

In light of this release, we are also incorporating a giveaway allowing members of the community who test the newly added features to have the chance of winning 2,000 CRS! The Cirrus Token can be either utilized on the Cirrus Sidechain or seamlessly converted back to the STRAT Token via a Cross-Chain Transfer.

Stratis presents to Industrial Bank of Korea

Stratis presented our DLT Solution to 75 delegates from Industrial Bank of Korea, headquartered in Seoul, South Korea.

South Korea is a hot spot for DLT technologies and this was a valuable opportunity for us to showcase our products and services in front of one of Asia’s most influential financial services groups.
We are also discussing future opportunities to present to similar trade delegations from major businesses in sectors such pharmaceuticals, healthcare and financial services.
With the launch of our Cirrus Sidechain Masternodes this month, it will now be easier, cheaper and faster for developers to build DLT and Smart Contract functions bespoke to their business needs. Stratis is committed to making it easy for businesses to adopt blockchain solutions and we believe our technology can greatly benefit large enterprises and financial services companies as well as government organisations whose systems operate within Microsoft’s .NET framework.

Stratis attends All-Party Parliamentary Group on Blockchain

To keep up with the latest thinking on the impact of blockchain, Stratis is participating in the All-Party Parliamentary Group (APPG) on Blockchain. We have attended evidence sessions at Westminster to gain insights from contributors from all corners of the industry.
The APPG states that its mission is: “To ensure that industry and society benefit from the full potential of blockchain and other distributed ledger technologies (DLT) making the UK a leader in blockchain/DLT’s innovation and implementation.”
Sessions this year have looked at blockchain and finance, the creative industries, next-generation services, healthcare, energy and environment. Members of parliament, government officials and industry leaders attended the sessions and have been presented demonstrations of real-world blockchain applications designed to educate policymakers.
As blockchain is becoming increasingly mainstream, it is vital that the benefits of the technology are highlighted to government organisations and businesses and we look forward to contributing to the APPG in the future.

Cirrus Sidechain & Smart Contracts in C#

Today marks a major milestone for Stratis with the launch of our Cirrus Sidechain Masternodes and Stratis Smart Contracts in C#.
Stratis becomes the world’s first blockchain to offer businesses and developers the ability to execute smart contracts on the Microsoft.NET core architecture. Allowing C# developers to develop auditable Smart Contracts and be confident with the results as true C# code is executed on-chain.
This release follows a successful two-week community testing phase during which Masternode Operators were able to familiarise themselves with operating a Sidechain Masternode and interacting with the Cirrus Sidechain.
The launch of the Cirrus Sidechain extends functionality for businesses operating on the Stratis platform. It includes the first smart contracts platform built entirely from the ground up in native C# on Microsoft’s .NET framework, combining the most popular enterprise programming language and the most widely-used enterprise framework.
As a result of this release, two new wallets are now available to be installed for end-users. Firstly, Stratis Core has been updated to fully support transfers to the Cirrus Sidechain, as well as incorporating the latest release of the Stratis Full Node. The second wallet sees the release of the Cirrus Core wallet, allowing users to create and manage a wallet, interact with Smart Contracts, deploy Smart Contracts and perform cross-chain transfers back to the Stratis Mainchain.
You can now make transfers to the Cirrus Sidechain from your Stratis Core wallet by entering the mainchain federation address and entering your Cirrus address generated from the Cirrus Core Wallet

Mainchain Federation Address: yU2jNwiac7XF8rQvSk2bgibmwsNLkkhsHV

The Cirrus Token can then be safely exchanged back to the Stratis Token via the Send to Mainchain dialog within Cirrus Core by entering the Sidechain Federation Address.

Sidechain Federation Address: cYTNBJDbgjRgcKARAvi2UCSsDdyHkjUqJ2

Expect to see more exciting news coming from Stratis as new contracts are developed and deployed onto the Cirrus Sidechain.

Cirrus Core

Stratis Monthly #4

As we move closer to the release of the Stratis Sidechain Masternodes, we have progressed extremely well with the current focus almost exclusively centring on testing and finalizing any outstanding items prior to the community testing phase.

Development Update

A total of 109 commits were made during the month of May, this encompassed 392 file changes and 14,219 additional lines of code. A short summary of the developments relating to the Stratis Sidechain Masternodes can be found below.
• Improvements to wallet transaction tracking
• Enhance the stability of the peer connectivity
• Reduction in indexing resource consumption
• Implementation of ‘burning’ STRAT for Sidechain withdrawals
• Optimization of the Federation wallet
• Introduction of a dynamic fee/reward for Masternodes
In addition to the core development, work has also been undertaken to deliver an additional wallet catering for the Cirrus Sidechain. A preview of the Cirrus Core wallet can be found below.

The Coherence Suite plays a pivotal role in allowing us to test edge cases within short timeframes. When testing many interconnected blockchain nodes it is important to monitor the overall network health through log interrogation. Contrary to the single instance scenario where a number of log files are relatively small, the whole network log monitoring is a more involved task.
Utilizing the Exception Viewer tool within  the Coherence Suite, the log monitoring begins before the node itself has started. A precise design of the NLog configuration targets specific components with additional tracing provided by Fody.
When the nodes are running, we periodically execute a scan across the whole network and automatically classify logs based on predefined rules. This approach allows us to pinpoint key areas of interest.

Stratis Sidechain Masternodes Update

We are pleased to announce the release of Cirrus Sidechain Masternodes will be on the 1st July 2019.
This release includes Stratis Smart Contracts in C# and will be made available for community testing two weeks prior on the 17th June 2019 to allow Masternode Operators to familiarize themselves with operating a Sidechain Masternode and to allow users to interact with the Cirrus Sidechain.
The community testing period is scheduled to last two weeks with the objective to receive valuable feedback. The network will then be restarted and announced as a full production release.

Stratis Monthly Update #3

April was an incredibly busy period at Stratis. With the continued development and testing of the Sidechain Masternodes being undertaken, there was a lot of preparation that went into exhibiting at the London Global Expo.

Development Update

During April it was agreed that we would bring the Sidechain codebase into the Full Node. This allowed development to progress whilst ensuring overall stability through the host of tests that are in place. A total of 76 commits were made to the codebase during April, this consisted of changes being made to over 350 files with 8,911 additions of code.
The development on the Full Node primarily focused on the Sidechains Masternode codebase, with the upcoming release both the development and testing teams have made significant progress in ensuring the Sidechain Masternodes are ready for release as soon as possible.
A summary of key developments during the month of April can be found below:

    • Enhanced shutdown sequence
    • Increased verbosity of Smart Contract logging
    • Experimentation of various database technologies to offer alternative storage options for clients
    • Enhanced throughput of cross-chain transfers
    • Stabilisation of the federation wallet and cross-chain transfers by achieving deterministic transaction creation
    • Improvements to transaction lookup performance

Utilization of the Stratis Coherence Suite across the development team is something that has been key during April. Testing the blockchain should never be limited to the validation of agreed node communication protocol. In the Stratis network there are two officially supported types of node implementations which behave slightly differently. This all makes low-level testing a crucial part of the overall delivery.
Stratis has extended the Wireshark Bitcoin Protocol Dissector to match changes introduced to Stratis Protocol on the top of original Bitcoin implementation. Stratis Protocol dissector is one of the primary tools we use when analysing and diagnosing issues between nodes at a network level.

The essence of the blockchain is the transactions which make up blocks. Since the transactions are represented as binary data in a HEX notation it would be very difficult to work with them in that format. The Stratis Transaction Builder is a tool that is used to provide a meaningful view of the individual blockchain transactions as well as help us create non-standard transactions.
The interface maps the parts of the transaction HEX to the decoded value so that when the transaction is edited using one of the human readable values the HEX code updates automatically.

Stratis impressed the crowds at “Blockchain Expo – Global” in London

2019 is all about acquiring enterprise customers for Stratis. After two years in development, all key modules of the Stratis platform went live in 2018, so the London edition of the Blockchain Expo global series of events was a great opportunity for Stratis to raise their profile on 25th/26th April.
Many visitors told us our stand was the best at the show. As a Platinum Sponsor of the event, Stratis was there in force, both on the booth and in the conference tracks.
Stratis subject matter experts, Paul Farrington and Rowan de Haas, presented “DLT for the Enterprise” and “Smart Contracts as Rules for Money – a Case Study” to packed arenas.

Rowan’s talk showcased work he recently led to put trade payments in the Construction Industry on the Stratis blockchain for Wildara, an Australian project management consultancy. The project demonstrated that the Stratis blockchain can automate Supply Chain payments as soon as deliveries for cement or any other project activities have been completed, removing administration, speeding the process and ensuring regulatory compliance for the parties involved.
The other item premiered by Stratis at the show was the Stratis Coherence Suite of testbed tools. As Stratis CEO, Chris Trew, observed:

When we developed the Stratis Platform we also built a testing suite optimized for blockchain, enabling us to move fast and provide transparency – we quickly realized this is something everyone building a blockchain network will need and the Stratis Coherence Suite was born.

The suite provides a set of viewers that can be dragged and dropped to provide real-time insight into areas such as network topography, chain status and node statistics, along with a set of transaction tools to create test data and aid investigation.
The Stratis team welcomed a continuous stream of visitors to the stand during both days of the expo, including many large enterprises interested in the value blockchain can bring to their businesses. Badges were scanned and every one of them has been followed up, with many conversations already in progress and meetings scheduled over the coming weeks. Based on the success in London, the team is already targeting a major event later in the year to take the Stratis experience to one of the other key regions of the world.
There was also additional collateral created for Stratis as a result of the London Expo, this included product specific leaflets, a promotional video and a number of giveaways to people visiting the stand. The promotional video can be found below, as well as all other collateral showcased at the expo.

Sidechain Masternode Applications

As we move closer to the release of Sidechain Masternodes, we can now move onto the final stage of registration and define Federated Members for network creation.
During the registration process, there was a requirement to submit a STRAT address that contained the relevant amount of collateral for the selected Sidechain Masternode tier.
To complete the registration process, applicants must prove ownership of the collateral address that was originally provided. There will be a 5-day window in which the applicants can prove ownership of the collateral address.
This final step of registration will need to be undertaken between the 6th May 2019 and 10th May 2019.
To prove ownership, you will need to follow the below process.

      1. Ensure you still have your FederationKey.dat file and know the passphrase
      2. Identify the Collateral Address you provided during registration
      3. Send the collateral requirement to the collateral address you provided

If the collateral amount already exists within the provided collateral address, simply send the entire balance back to the provided address.
After the 10th May 2019, Federated Members will be defined for the Cirrus Sidechain.
Please note that in no instances will Stratis attempt to contact you requesting you to send funds to an address.

Stratis 2019 Development Roadmap

Today we are pleased to announce our development roadmap for the remainder of 2019. The roadmap focuses on both adoption of the Stratis Platform and an increase in utilization of the Stratis Token.

Java and JavaScript Support

Introducing support of new programming languages inherently increases the audience that the Stratis Platform appeals to. The addition of this support will enable a new development community who are not familiar with the Microsoft .NET Core framework to interact with and develop on the Stratis ecosystem.

Breeze Privacy Protocol for STRAT

The further development of the Breeze Privacy Protocol will include a new version of the Breeze Wallet with enhanced security. In addition, we are working on bringing Segregated Witness support to the Stratis network to enable native Privacy Protocol support.

Proof-of-Stake Sidechains

The introduction of further consensus algorithms for Stratis Sidechains will grant even more bespoke use-cases on the Stratis Platform. We envision the development of further consensus algorithms on Stratis Sidechains will negate the requirement for the forking of source code. This will drive collaboration and encourage development on the already established Stratis codebase.

Sidechain Masternodes

Stratis Sidechain Masternodes will enable holders of the Stratis Token to operate as a block producer on a Stratis Sidechain. The first Sidechain Masternodes will be on the Cirrus Sidechain network, these Masternodes will earn rewards from transactions fees and smart contracts executed on the network.

Stratis STO Platform

Whilst we firmly believe there is still a market for Initial Coin Offerings (ICO), Stratis will extend the functionality of the Stratis ICO Platform to cater for the regulatory requirements needed to conduct a Security Token Offering (STO).
The support for STO’s will also bring additional features to the ICO Platform, with the inclusion of the platform being Smart Contract aware. This will allow token issuance contracts to be utilized during a crowdfund.

Stratis Core 2.0

The release of Stratis Core 2.0 will incorporate new features that will enable interaction with other components within the Stratis ecosystem. The focus of this update is to continue to provide a simple user-experience from within the GUI, allowing users to manage their tokens and deploy new smart contracts with ease.
These features include:

  • Token awareness to cater for tokens issued on a sidechain
  • Validation and deployment of a smart contract
  • Voting capability to interact with deployed sidechains

Stratis Mobile Wallet

A mobile application that caters for the sending and receiving of the Stratis Token will be delivered for both Android and iOS. This mobile wallet will allow users to simply transact on their mobile device utilizing a secure, functional and elegant mobile application.

Stratis Payment Gateway

Stratis will develop a Payment Gateway that can be deployed by third-parties to utilize the STRAT token as a form of payment. The payment gateway will be designed to allow other tokens launching on the Stratis Platform to seamlessly implement the Stratis Payment Gateway for their requirements.

Unity SDK Integration

Unity is the creator of the world’s most widely used real-time 3D development platform. Stratis will provide an SDK for Unity developers, enabling the utilization of the Blockchain during game development. This unleashes a wide range of functionality for in-game token and asset markets where the blockchain is a perfectly suited technology.

The above development activities represent the core work that will take place at Stratis over the remaining course of this year. There are additional internal developments that we aim to deliver within the coming months, which will be detailed in due course.
