Despite the increasing attention that crypto is receiving on Wall Street and among retail investors, an awkward reality persists: most existing public chains are trapped in a closed loop of the "crypto circle," disconnected from real-world services, data, and user habits, making it difficult for blockchain to integrate into the lives of ordinary people. At the same time, developers want to focus on business logic rather than spending a lot of energy on integrating oracles, maintaining nodes, or handling off-chain data.

Against this backdrop, the real-world blockchain Rialo aims to break down the barriers between blockchain and the real world, enabling teams to deliver production-ready applications as easily as Web2 development, allowing blockchain to seamlessly integrate into the operational logic of the real world, much like smartphones.

What is Rialo?

Rialo is a blockchain developed by Subzero Labs specifically for the real world, but its positioning goes beyond the traditional Layer1, Layer2, or Layer3 frameworks, fully named "Rialo isn’t a layer 1."

Using a metaphor from Ade Adepoju, co-founder of Subzero Labs, in Fortune magazine: "It's like the evolution from the iPod to the iPhone — we don’t need another device that can only play music; we need an all-in-one tool that integrates a camera, internet, and GPS."

The core goal of Rialo is to lower the barriers to using blockchain, allowing developers from non-crypto fields to easily build applications. Its most notable feature is "native connection to the real world": for example, developers can directly call web information (such as FICO credit scores) in smart contracts without relying on third-party oracles; users can log in with familiar identities like social accounts or emails, without having to learn wallet operations from scratch.

Fabric Ventures explained why it invested in Rialo, stating that Rialo changes the focus of blockchain L1 by embedding the core functionalities needed by real-world developers directly into the protocol. Calls, data flows, timers, and cross-chain operations become native instructions rather than relying on external calls. Oracles, cross-chain bridges, indexers, and other "traditional" infrastructure may no longer be necessary.

Team and Funding Background

In early August, Subzero Labs announced the completion of a $20 million seed round of financing, led by Pantera Capital, with participation from Sui developer Mysten Labs, as well as Variant, Hashed, Fabric Ventures, Coinbase Ventures, Mirana Ventures, Susquehanna, Edge Ventures, Flowdesk, and others. According to Fortune magazine, CEO Ade Adepoju stated that this financing was completed in the first quarter of this year and involved equity and token warrants.

Members of the Subzero Labs team have previously worked at companies or projects such as Meta, Apple, Amazon, Netflix, Google, TikTok, Citadel, Mysten Labs, and Solana, possessing rich experience in blockchain, artificial intelligence, distributed systems, and hardware.

• Co-founder and CEO Ade Adepoju: 30 years old, residing in New York City, previously worked at chip manufacturer AMD, and later served as an engineer at Dell and Netflix. At the end of 2021, Ade Adepoju entered the crypto field as a founding engineer at Mysten Labs (as of February 2024).

• Co-founder and CTO Lu Zhang: Former engineer at Mysten Labs.

How Does Rialo Work?

Although Rialo has not disclosed its blockchain architecture, its brief introduction indicates that its operational logic revolves around "combining RISC-V, Solana VM compatibility," "reducing friction," and "native integration," which can be understood from several perspectives:

• Combining RISC-V and Solana VM Compatibility: Rialo is committed to reducing the need for middleware such as cross-chain bridges and oracles, integrating RISC-V smart contracts and Solana VM compatibility.

It is worth mentioning that in April of this year, Vitalik Buterin proposed at the Ethereum Magicians forum to replace the Ethereum EVM with the open-source instruction set architecture RISC-V to enhance scalability. In the vision for the next decade of Ethereum's "lean Ethereum" development released by Ethereum Foundation researcher Justin Drake in August, it was pointed out that Ethereum will undergo significant upgrades at the consensus layer, data layer, and execution layer, possibly building EVM 2.0 based on the open-source RISC-V instruction set. Vitalik Buterin explained that replacing ZK-EVM with RISC-V could significantly improve the efficiency of Ethereum's execution layer, addressing one of the major scalability bottlenecks and greatly enhancing the simplicity of the execution layer.

• Developer-Friendly Technical Architecture: Unlike traditional public chains, Rialo was designed with the capability for "real-world interaction" embedded from the start. For example, a single line of HTTPS call in a smart contract can extract real-time data anywhere and seamlessly integrate any off-chain API into the smart contract. Additionally, Rialo optimizes the programming experience for smart contracts, introducing mechanisms like "event-driven" and "asynchronous processing," similar to traditional software development, allowing developers to write logic as simply as regular code.

• User Experience of "De-Blockchainization": Rialo aims to reconstruct the identity system, allowing users to log in with email, SMS, or existing social identities as a Web3 passport. Furthermore, Rialo will support sending encrypted messages. Rialo claims that transaction confirmations occur at sub-second speeds, with stable and predictable fees, avoiding issues like "gas fee surges" and "sandwich attacks" common in traditional public chains; at the same time, Rialo supports familiar Web2 features like 2FA and scheduled transactions.

• Ecosystem Synergy, Breaking Down "On-Chain and Off-Chain" Barriers: Rialo's underlying protocol will support direct interaction with various real-world services, such as payment systems and weather data. This "native integration" capability allows applications on Rialo to cover a wider range of scenarios.

Conclusion

When applications are simple enough and scenarios are everyday enough, crypto technology has the potential to truly step out of the "small circle."

Of course, Rialo still faces challenges: how to maintain decentralization while connecting to the real world? How to balance decentralization and compliance? How to balance data openness and privacy protection?
