# Abstract 'The Portal' - Digital Amusement Park

> Abstract develops 'The Portal' as a digital amusement park that simplifies the complex user experience of existing blockchain games. The solution offers a 'No-Crypto' user interface where users log in via email and automatically receive a custodial wallet. Interaction occurs through fiat-backed $ARCADE tokens on the Abstract Chain, which launched in January 2025 as a consumer-centric blockchain.

## Description

Proof-of-Attendance Protocol (POAP) was developed in 2019 and enables organisers to distribute attendance NFTs to visitors. Each NFT is event-specific, dated, and tamper-proof. Abstract Chain (2024) is a new blockchain infrastructure specifically for consumer apps and gamification, building on these concepts and integrating event NFTs into broader community mechanisms.

The Proof-of-Attendance Protocol (POAP) launched in 2019 and has since issued over 100 million event NFTs. The concept is simple: organisers create an event-specific NFT; visitors receive it by scanning a QR code on site or via a link. The NFT is a tamper-proof proof of attendance, dated by the blockchain timestamp. Applications: (1) Community building — POAP holders of certain events gain access to exclusive channels or follow-up events. (2) Loyalty programmes — repeat visitors receive special benefits. (3) Collectible value — limited event NFTs from well-known conferences or concerts have secondary market demand. Abstract Chain (2024, Ethereum Layer-2) positions itself as infrastructure for these consumer blockchain applications: low gas fees, easy onboarding, optimised for gamification and community mechanisms. Abstract Games and similar initiatives use NFT mechanics for event interaction and prize distributions.

## Benefits

- Companies can reach new target groups while developing innovative revenue streams through blockchain integration.
- Users benefit from financial incentives through play-to-earn mechanisms and can actively participate in platform development.
- The no-crypto user interface makes blockchain technology accessible to mainstream users without requiring technical knowledge.
- Three diversified revenue streams through transaction fees, sponsorship, and premium subscriptions create stable business foundations.
- DAO governance enables authentic community participation and leads to user-driven platform improvements.
- The simplified user interface reduces training effort and allows employees to focus on value-adding customer service.

## Challenges

- Companies must invest in new technology partnerships and train their teams in blockchain-based business models.
- Integrating modular blockchain architecture with ZK proofs requires specialised technical expertise and ongoing maintenance.
- The balance between user-friendliness and the benefits of decentralised technology must be carefully calibrated.
- Employees need to familiarise themselves with new concepts such as DAO governance and token economies.

## Technology foundation

The project is based on the Abstract Chain, a consumer-centred blockchain launched in January 2025 and specifically developed to popularise cryptocurrencies. The platform uses a modular blockchain architecture with ZK proofs for scaling and offers a simplified user interface without direct crypto contact for end users.
