Paradigm New features, Opportunity to Earn Up to 100%, BNB Added

Biweekly update 26th July — 9th August

Development Chain Dev Update #4

As always, the latest Dev Update is packed with exciting topics, this time including:

  • New textual address format for payments: Bech32 Standard
  • Technical documentation updates
  • Initial threat model
  • Tools & tutorials to get you started on Chain development
  • Transaction accounting model update
  • Next steps towards Public TestNet

New Textual Address Format for Payments: Bech32 Standard

Previously, Chain used hexadecimal formatting. However, during the iteration & continuous improvement of the flow and interface, the developers have discovered some problems with this address format, for example:

  1. Confusion caused by representing different items at the same time (e.g., different types of addresses, transaction identifiers).
  2. Lack of robust error-detection mechanism (e.g., unable to detect cases where someone types or copy-pastes it).
  3. The addresses are too long for the default payment addresses that support threshold multi-signatures (briefly described in dev update #2).

To address these issues, the team evaluated the options and selected representing payment addresses using the Bech32 standard used in Bitcoin, Lightning Network etc. This representation is compact, simple, visually unambiguous and comes with solid error-detection. For the human-readable address part, developers proposed the following prefix conventions:

  1. cro: for addresses on the mainnet
  2. tcro: for addresses on the public testnet
  3. dcro: for addresses in local test executions or on private developer testnets.

For example, this is how an address would like on the mainnet: cro1pe7qg5gshrdl99m9q3ecpzvfr8zuk4h5xxnlp9

(in a local developer test execution, this address would be: dcro1pe7qg5gshrdl99m9q3ecpzvfr8zuk4h5rm547c.)

Technical Documentation Updates has updated and extended the technical documentation, with a stylish repolishing thanks to the marketing team:

Some highlights on what’s new in the technical documentation:

  1. Initial threat model
  2. “Getting started”
  3. Transaction Accounting

Initial Threat Model

As outlined in the Chain Technical Whitepaper, security remains a2 top priority. One of the important stepping stones security foundations, as mentioned in the whitepaper, is threat modelling. It is a systematic approach to identify potential security threats by decomposing and enumerating system components.

In collaboration with the security team, the tech team developed the initial threat model for select core components of Chain. The model is mainly based on the STRIDEframework originally developed at Microsoft. You can read more in the hosted version of the technical documentation:

Getting-Started Tools & Tutorials

To help you get started and stay up to speed on the rapid development of Chain, the team has updated the documentation for beginners & developer tools.

In the latest update, the Crypto team has simplified the initial developer workflow and added the “init everything” command that helps to bootstrap the environment needed for developing Chain. You can read more about it in the latest main READMEfile, as well as in the tutorial on the main technical documentation page.

Transaction Accounting

In Dev Update #2, the team mentioned that Chain would be using the UTXO transaction accounting model, which functions well for payment operations.

Considering that certain network operations (e.g., staking) function better in the account-based model, developers have decided to support both the UTXO & account-based models in the style of chimeric ledgers, where one could transition between either model using special transaction types. You can read more about the motivation behind this design and how it works in the technical documentation.

Next Steps Towards Public Testnet

As the team prepares for the launch of the first version of the Public testnet, the team would like to share more information about its implementation and actions taken towards its launch:

  • Chain will run on the current Testnet prototype code;
  • The sample UI web implementation of the Chain wallet backend will be released, so that developers can start working with these on the testnet;
  • Security Bug Bounty programme will be enhanced to include potential Chain vulnerabilities in its scope;
  • The team will start engaging third parties for architecture and code security audits;
  • The infrastructure, including various web services, will likely be operated by at this stage, though the team is in discussions with several industry partners to host Council Nodes for the next phases of the Public Testnet and beyond;
  • The technical whitepaper will be updated in accordance with some of the details described in the technical documentation.

The tech team plans to iterate on the Public Testnet in several phases to run a more complete (the team has several exciting features still in the backlog to implement) and more robust code that will make it easier for third parties to participate in the network operations.

Social encounters is pleased to share that it has officially on-boarded the first batch of Ambassadors. You will be able to identify them through their social media and/or community handles as follows:

As the first step into the program, Crypto’s ambassadors will have (more) presence in the social media platforms and/or community channels, and you will see/hear from them even more in the time to come.

The team is really excited to accelerate the world’s transition to cryptocurrency, together with the Ambassadors and valued community members.

The Crypto team also anticipates to onboard the next batch of Ambassadors soon to measure up with the growing platform and community.

Growth Portfolio outperforms benchmark returning +109% YTD and +74% since inception

Please find below the first performance report of Crypto Invest covering returns (in USD) from inception through the end of June 2019.

Performance Highlights:

  1. Each of the portfolios outperformed the S&P 500 in every reporting period. Growth +109%, Balanced +75%, Conservative +47% Year to Date (YTD) and +74%, +49%, +35% since inception (7 Oct 2018) respectively.
  2. Against the Eureka Hedge Crypto Hedge Fund Index — an index of the most prominent institutional funds in crypto — the Growth portfolio outperforms in every period. +109% vs +93% YTD and +74% vs 40% since inception. Better than institutional performance starting with as little $20 USD. That’s democratizing quant trading!
  1. Volatility: The maximum drawdown (% drop from peak to trough) for all strategies (15–24%) are comparable to that of S&P 500 and significantly less than the Crypto HF Index (39%).
  2. Risk-Adjusted Return: Compared with S&P 500 and Crypto HF Index, all three strategies deliver higher Calmar & Sharpe ratios, which are indicators of stronger returns at a comparable risk level.

Calmar Ratio: The lower the Calmar ratio, the worse the investment performed on a risk-adjusted basis over the specified time period; the higher the Calmar ratio, the better it performed.

Sharpe Ratio: Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.
