Blockchain-Ads — Bringing the ad industry into the Web3 world

Blockchain-Ads — Bringing the ad industry into the Web3 world

Guest blog from Vlad Chejkov, Blockchain-Ads Founder

As the founder of Blockchain-Ads, I am thrilled to be featured in the Ecosystem Spotlight, where we are shedding light on the revolutionary changes we are bringing to the Web3 industry.

Blockchain-Ads is specifically designed to bridge a gap in the market where Web3 brands struggle to reach their ideal customers. Traditional ad networks often restrict crypto-related promotions, and none of the crypto ad networks currently allow targeting based on users’ on-chain behaviour.

Blockchain-Ads platform offers Web3 brands the opportunity to connect with their target audiences efficiently and effectively, outperforming the competitors 10 to 1.

Our collaboration with Partisia Blockchain has been fundamental to our success. Their pioneering multiparty computation (MPC) and zero-knowledge (ZK) technologies serve as the backbone of our solution. They ensure user data is processed securely while facilitating targeted advertising. This approach respects user privacy and transforms the digital advertising landscape without revealing any underlying data or compromising user privacy.

Currently, we are at an exciting juncture. We are preparing to launch Partisia smart contracts on testnet in the first half of May. It is a crucial step that will help us refine our solution in a secure environment before launching on the mainnet.

As we forge ahead, our mission is clear: to disrupt the conventional, centralized advertising industry with a decentralized, privacy-preserving, and cost-effective solution. We aim to redefine privacy and user control in the digital advertising landscape, tailoring specifically to the needs of Web3 brands.

For more insights into our progress and to stay abreast of our exciting journey, follow us on Twitter or reach out through our website. We are proud to be part of the innovative Partisia Blockchain ecosystem and look forward to reshaping the future of privacy-preserving advertising in the Web3 space.

KIN — Web3 ad-free search engine

KIN — Web3 ad-free search engine

Guest blog from Gordon Povey CEO & Founder at Kin

Kin is a Web3 ad-free search engine built around community, transparency, and privacy. The prototype has been operational for over a year and on 1 May 2023 we launched the Kin beta https://searchkin.com.

Our aim is to be a disruptor and so we are highly differentiated from incumbent search engines like Google.

We are building a community of users that believe in Web3 principles. We use blockchain and a smart contract for transparency. We will use multiparty computation (MPC) technology to ensure maximum privacy for users at all times.

We have thrown out the traditional advertising business model where the user is the product to be sold to advertisers. Instead, we become a broker of both information and also online products.

So metaphorically, if you want to go to the library for information, we become your personal librarian and try to find exactly what you are looking for without trying to sell you anything or distract you along the way. Then, if you do want to go to the shopping mall (metaphorically) to buy something, we are like your personal shopper trying to find exactly what you want and can even uncover local or artisan products that are usually difficult to find online.

We generate revenue as a broker only when we find what you really want. By taking this approach, we find information that is less skewed by large commercial SEO budgets, and we can discover online products that are often hidden by advertising and brand dominance.

We knew we needed to work with a Layer 1 blockchain so that we could mint our own tokens. We also knew that we needed a secure way to process user data while maintaining complete privacy. The fact that Partisia Blockchain was offering not just a blockchain, but also MPC capabilities made it a front runner.

We have just launched the Kin beta. The organic search (for web, news, images and videos) is working extremely well. We believe it provides better results than the incumbent search engines (try it for yourself and compare our results to other search engines).

We still have work to do on the shopping searches, which are limited and UK-centric at present. We will also be turning on the user rewards system very soon. To fund future developments, we are opening another token pre-sale, which will allow early supporters of our project to buy tokens at a discounted price. The funds will be used for the product launch and marketing, and for ongoing developments such as the implementation of our community-based training (using xAI methods) which is included in a patent we recently had granted.

Bias and Corruption Free Random Number Generation Through MPC

Bias and Corruption Free Random Number Generation Through MPC

Most may not know, but generating random numbers is hard. It is quite surprising because many people will think, “well, I can just come up with a random number off the top of my head!” However, randomly coming up with a number in your head, as well as other solutions to generate random numbers has fundamental flaws. And this is a big problem. Generating a fair unbiased random number is critical. In fact, random number generators are used everywhere.

The first place many would think of random numbers being useful is in games of chance. But would you be surprised if you knew that reading this article required the use of a random number generator? The website hosting this article is protected by a cryptographic key, which relies on generating a random set of values to be used for the encryption key.

Generating numbers at random is difficult. At a high level, there are two main issues with generating random numbers: predictability and bias/corruption issues.

Figure 1: RNG use cases are wide and varied

The predictability issue for RNG can be seen in both human- and machine-generated random numbers. For example, there is a famous problem called Benford’s Law that states any random number that someone thinks about has a 30% chance of starting with the number 1. When you want to have a chance of a number being generated to be equal in percentage, then this becomes a problem. If you use a computer program to generate random numbers, you are using a structured code. This means, after multiple iterations, someone can reverse engineer the numbers to find the pattern and predict what the next number could be, especially if the code being used is weak.

Figure 2: Predictability issues in RNG

From a bias and corruption perspective, the current systems can also be gamed to give favor to someone. For instance, if a set group of people decide they will choose random numbers and run through some function to compute a random number, one person may withhold showing their number until they see what the other people have chosen. Then, once he knows the numbers of the other participants, he can choose a number that would compute the random number to his favor. From a machine generated random numbers, since most systems have a central system that is generating the numbers, anyone who has control of that system could also manipulate the numbers being generated to their favor.

Figure 3: Bias and corruption issues in RNG

So how can we create a system where it is both unpredictable and bias free? Through MPC and Partisia Blockchain, we can solve both problems. Through smart contracts, players in the system generate a random number. This random number is then privatized and sent into the PBC blockchain. A zero-knowledge computation is done, in a similar way as done through secret sharing and through a computation, a random number is revealed.

Figure 4: Generating unbiased RNG that is incorruptible

Through combining multiple players and secret sharing, developers can create a system to come up with a random number that is free from bias, incorruptible and impossible to predict. And Partisia Blockchain’s smart contract language will afford developers to customize this solution to their specific requirements.

By creating a programming language that allows for developers to use MPC in a generic way, Partisia Blockchain Foundation has made the creation of applications that can harness the power of MPC for different use cases a possibility. Partisia has been at the forefront of providing private MPC solutions since 2008. And by layering this technology on top of an interoperable and scalable blockchain, Partisia Blockchain is now paving the way for anyone to create solutions that can balance privacy and transparency to build trust.
