Stay Stealthy
Stay Stealthy

Most cryptocurrencies today have transparent blockchains, so that transactions taking place within them are openly verifiable and traceable. However, users want to have the opportunity to transact in a secure and anonymous manner. Moreover, in a business environment a non-disclosure of a commercially sensitive information is a crucial thing, that helps you to avoid showing vulnerabilities to your competitors.

So there is a need for private financial transactions and that’s why we have implemented the Stealth Transactions feature into the Gravity Business Framework.

There is a certain bias in the digital world that stealth transactions are mostly used for illicit activities, but we believe that the ability to transact in stealth mode will facilitate further business adoption of the technology. This makes it a must have feature for a public blockchain in order for it to be adopted by SMEs.

Gravity Solutions: On the Way to the Marketplace 3.0
Gravity Solutions: On the Way to the Marketplace 3.0

A marketplace is an online platform where a customer can compare and buy a wide range of goods and services from several sellers at once. Marketplaces became a popular and necessary solution for SMEs (Small and Medium Enterprises) because they significantly extend their outreach to a global level and offer completely new methods for selling goods and services. Small enterprises found the idea that there’s no need to maintain and promote their online shop attractive, since those tasks can be rather expensive.

The key objective of early marketplace development is to extend the the availability and access to a range of product to the limit, which is not available for an offline retailer. The second stage of marketplace development is to enlarge the audience to an international scale. This is the stage where all marketplaces are currently. However, these stages imply a quantitative increase only, and it seems the next evolution will involve the qualitative optimization of the marketplace.

More on the decentralized marketplaces and DEX as a new marketplace see here in the full article on Medium.

To Kill a Middleman: Why Blockchain is Vitally Important for Small Businesses
To Kill a Middleman: Why Blockchain is Vitally Important for Small Businesses

The term “Blockchain” has been a buzzword for a while. Everyone has heard of blockchain, but few use it outside of cryptocurrency trading and speculation. Usually, people talk about “creating trust where there is none” when referring to blockchain. You may also hear things along the line of, blockchain helping to “kill the middleman”.

However, many may not truly understand, what “the middleman” is, how to get rid of it, and, the main thing, why blockchain hasn’t been adopted on mass yet.

A full article about the issues which discourage SMEs to use blockchain and how Gravity Protocol is going to solve these issues - here on our Medium blog.

Electronic Document Circulation: Gravity Extended Contract
Electronic Document Circulation: Gravity Extended Contract

One of our most important missions for broader business adoption is to develop a full solution that includes technical, legal and financial infrastructure and enables users to create and sign legally binding documentation within the blockchain. In order to achieve this, there must be transparency as well as the ability to track down the contract at any stage from the signing of an agreement to the transaction stage. For that, we’re going to implement a full solution based on Gravity blockchain using something called Extended Gravity Solutions Contracts.

While large organizations have teams of legal professionals, small and medium-sized Enterprises lack such resources, so they require a framework that addresses all of the standard business processes that are part of standard operations as well as the ability to conduct agreements with other counterparties.

More information on the problems of legal significance, Ricardian contracts, digital signture and Extended Gravity Solutions Contracts see in the full article on Medium.

Testnet Environment For Attack Modelling: The Methodology
Testnet Environment For Attack Modelling: The Methodology

This article will cover the methodology we will be using to explore the possibilities and limits of the Gravity emission model. The main idea of this research is to explore the flexibility of the model, as well as its strengths and weaknesses. The tools that we’ve created for modelling user behavior and further statistics analysis are available in our GitHub repo. This will be the first in the series of articles on the subject.

See the full article on Medium.

How the Gravity Protocol Team Implements a Security Development Lifecycle
How the Gravity Protocol Team Implements a Security Development Lifecycle

Ensuring the security of a blockchain network

Recent security incidents with the DAO, Ethereum Krypton 51% attack, and “epic” vulnerabilities discovered in EOS by Chinese security researchers at Qihoo 360 (luckily fixed) once again tell us that security concerns are paramount for open blockchain networks supported by communities.
 First of all, we need to understand — “What is security?” The CIA security triad model, composed of three areas; (1) Confidentiality, (2) Integrity and (3) Availability will be referenced throughout this paper.

According to the National Institute of Standards and Technology (NIST):

Confidentiality refers to “The property that sensitive information is not disclosed to unauthorized individuals, entities, or processes”;
Integrity is defined as the “guarding against improper information modification or destruction, and includes ensuring information non-repudiation and authenticity”.
Availability references the concept of “ensuring timely and reliable access to and use of information”
What does it take to ensure security in your software system? It means that your engineering team has a certain level of maturity and implements rigorous Secure Software Development Lifecycle (S-SDLC).

The S-SDLC process ensures that security assurance activities such as code review, architecture analysis, and attack modelling, are an integral part of the development effort. The main advantages of pursuing a Secure SDLC approach with regards to an open blockchain are:

  • Increased quality and security of software as security is a continuous concern.
  • Awareness of security considerations by stakeholders and the community.
  • Early detection of flaws and vulnerabilities in the system.
  • Overall reduction of intrinsic business risks for the community.

Since Gravity Protocol is an open blockchain offering solutions for small and medium businesses, secure software is our highest priority. See how we implement similar to SDL development process here on our blog.

Gravity IPFS: Off-chain Data Storage

One of the main problems concerning scalability of the blockchain is the limited size of it’s blocks. This essentially makes it impossible to store more complex data than transaction history, registry entries, and hashes in a block. Therefore, the majority of public blockchains have not yet surpassed the “transactional” stage of development.

Gravity strives to become not only a blockchain of transactions/for transactions, but, above all else, a distributed protocol for managing the sum of all possible data, and the use of distributed data stores such as IPFS is inevitable in this task.

IPFS organizes distributed data storage on users’ computers. This is the same concept BitSwap Ledgers implemented in IPFS, a scalable register where the distribution of content blocks is similar to the distribution in the Kademlia DHT. These registries deal only with peer-to-peer relationships without regard to latency, bandwidth, or network availability, making IPFS a versatile and extensible decentralized file system.

Thus, after IPFs integration, it becomes possible store only the hash data on-chain. The data itself will be stored off-chain, in IPFS.

The ability to store just the hash data on-chain, significantly decreases the size of data to be stored, which slows down the speed of chain bloat, thus decreasing the resources required for blockchain nodes, as well as the time it takes to resync and replay, which is a huge problem on existing blockchains that try to store unnecessary data on their chains.

More information on how IPFS works and how it is implemented into Gravity Protocol see here.
