OneSelf World Unveils Blockchain Ad Platform 'MyB Adchain'

## Oneselfworld Unveils 'MyB AdChain,' an Innovative AI and Web3-based Advertising Platform Oneselfworld, a leading company in the Web3 marketing sector, has officially unveiled 'MyB AdChain,' a platform poised to bring a new wave to the digital advertising market through an innovative convergence of Artificial Intelligence (AI) and Web3 technology. This platform transcends the limitations of traditional advertising by building a user-centric, transparent, and efficient advertising ecosystem, thereby attracting significant industry attention. At the core of MyB AdChain lies Oneselfworld's exclusively patented 'W3ID (Web 3.0 Identity)' technology. W3ID provides each user with a unique digital wallet and a Soulbound Token (SBT), thereby creating a foundation for transparently recording advertising participation history and enabling users to receive fair rewards accordingly. From an advertiser's perspective, this means they can precisely target only users who can generate real results, maximizing the efficiency of their advertising budget. Moving away from existing opaque and inefficient advertising identification methods, it presents a sustainable model that provides value to both advertisers and users. MyB AdChain has adopted an innovative approach that differentiates it from existing reward-based advertising networks. Beyond mere ad exposure rewards, it has introduced 'storytelling quiz advertisements' that encourage user participation. This interactive advertising format not only dramatically increases the ad page visit rate of mobile media users but also creates synergy between the AI recommendation engine and W3ID-based precise targeting, significantly improving ad conversion rates, according to the company. The actual performance revealed by Oneselfworld clearly demonstrates the potential of MyB AdChain. Since applying W3ID technology to the MyB service, it has recorded an Average Revenue Per User (ARPU) more than 4 times higher than the industry average. Furthermore, in operating media outlets, it achieved approximately 8 times higher advertising revenue compared to existing reward-based ad networks, proving its effectiveness. This suggests that it not only increases advertising effectiveness but can also fundamentally improve the profitability of media outlets. Currently, MyB AdChain is successfully integrated into major mobile apps such as the medical app ‘Ttokdak’ and the financial app ‘Treasurer,’ and is actively operating. Oneselfworld expects that if all confirmed media integrations are completed by the end of the year, it will achieve approximately 5 million MAU (Monthly Active Users), and plans to rapidly expand its market share. Jo Chang-hyun, CEO of Oneselfworld, emphasized, "MyB AdChain goes beyond being just a reward-based advertising solution; it aims to be a 'user-experience-based advertising operating system' for mobile media." He expressed his ambition, stating, "This platform will not only maximize media ad revenue but also significantly contribute to improving user retention and visit rates, thereby setting a new advertising standard for the Web3 era." Attention is drawn to what kind of impact MyB AdChain will have on the digital advertising market.
