How Ephemeral Rollups Impact Solana Gaming | Andrea, MagicBlock
By Lightspeed
Published on 2024-09-24
Discover how MagicBlock's innovative ephemeral rollups are transforming the Solana gaming landscape, offering high-performance solutions for on-chain games and applications.
MagicBlock's Ephemeral Rollups: Revolutionizing Solana Gaming
In a recent episode of the Lightspeed podcast, Andrea Fortunio, Co-founder of MagicBlock, shed light on the groundbreaking technology of ephemeral rollups and their potential to transform the Solana gaming landscape. This in-depth discussion explored the current state of the Solana gaming industry, the benefits of ephemeral rollups, and the security implications of utilizing optimistic rollups in on-chain gaming.
What is MagicBlock?
MagicBlock is a high-performance engine for fully on-chain games and applications built on the Solana blockchain. The company's innovative approach aims to enable new consumer experiences by leveraging the power of blockchain technology. Andrea Fortunio, the co-founder of MagicBlock, explains:
"MagicBlock is, as we call it, a high-performance engine for fully on-chain games and fully on-chain applications. So, you can use our stack to build any sort of application that is running entirely on-chain."
The Power of Fully On-Chain Games
One of the key focuses of MagicBlock is enabling fully on-chain games. But why is this important? Andrea highlights several key benefits:
-
Permissionless composability: When a game is built entirely as a smart contract, it becomes an open platform. This allows anyone to build on top of the game, introducing new levels, progression systems, or even prediction markets without the need for oracles.
-
Verifiability and trustless compute: High-stakes games no longer need to rely on centralized parties for operation, reducing the risk of fraud or manipulation.
-
Persistency: Games can be deployed once and exist indefinitely on the blockchain, eliminating the need for ongoing server maintenance and enabling digital experiences that can last forever.
Andrea emphasized the importance of these features, stating:
"We figure out that some of these properties were only possible for games that were built entirely on chain. And so, as we start to build some of those games ourselves, we got pretty excited about those experiences and we decided to build the full stack that could bring those experiences, that could enable those experiences in terms of completely brand new category potentially of games."
The Solana Gaming Landscape
While the success of MagicBlock is tied to the broader Solana gaming ecosystem, Andrea sees potential beyond just gaming applications. He explains that the technology they're developing can be applied to various high-performance applications that require real-time latency and customization.
"I definitely love to see the gaming ecosystem also on a succeed. But I think the tech that we're building goes way beyond just video games," Andrea notes.
This broader application of MagicBlock's technology could potentially enable a new category of applications that share similar properties to on-chain games, such as decentralized finance (DeFi) platforms or other high-performance blockchain applications.
AAA Games vs. Mobile Gaming
When discussing the focus of MagicBlock, Andrea clarified that their technology isn't limited to AAA games or mobile games exclusively. He explained that studios building highly polished AAA games often come from traditional gaming backgrounds and integrate blockchain technology primarily for assets like NFTs or tokens.
On the other hand, fully on-chain games tend to be more experimental and are typically developed by smaller studios or indie developers who can afford to take more risks. Andrea expressed enthusiasm for the potential of mobile gaming in the blockchain space, particularly with the upcoming release of the Solana SAGA 2 device:
"I'm so bullish on SAGA 2. I cannot wait to see what happens when those 100,000 devices, whatever number they manage to sell, it's going to start shipping and they get into the hands of users and we're starting to have more consumer experiences, namely games on that app store."
The Innovative Ephemeral Rollups
The core innovation behind MagicBlock is the concept of ephemeral rollups. This technology allows developers to build on Solana while delegating certain transactions to fast SVM (Solana Virtual Machine) instances deployed worldwide when needed. Andrea explains:
"Ephemeral rollup is, I guess, a Solana extension. It's a way for developers to build on Solana and then delegate, offload, on-demand, some of their transaction if they need and when they need it to do this fast SVM instances that are deployed all over the world."
This approach enables real-time latency and optimization at the runtime level without requiring developers to leave the Solana ecosystem or use a separate Layer 2 solution.
How Ephemeral Rollups Work
The process of using ephemeral rollups involves several steps:
- Developers build a smart contract on Solana as they normally would.
- When low latency is needed, they can interact with an on-chain smart contract to delegate certain state to an ephemeral validator.
- The ephemeral validator clones the relevant state and allows for faster transaction processing.
- Transactions can be run on both Solana (for unlocked state) and the ephemeral rollup (for delegated state).
- When the process is complete, the state is committed back to Solana after verification by a security committee.
This system allows developers to maintain composability with the base layer while achieving latencies as low as 50 milliseconds, which is crucial for real-time multiplayer games.
Security Implications of Optimistic Rollups
Addressing concerns about the security of optimistic rollup systems, Andrea explained that MagicBlock has implemented a dynamic fraud proof system. This system allows developers to specify a fraud proof window, during which any honest party can raise a challenge.
Additionally, a set of "light clients" sample and verify that the node is not cheating, signing off on state commitments before they are finalized. Andrea elaborates:
"It's additional like clients have to sign off the state commitment and basically signaling that they are not raising a challenge and everything happened correctly and the validator is not cheating. And only when the threshold of signature is reached and the challenge window elops, then the state becomes final."
This approach aims to provide good security properties for the ephemeral rollup system while maintaining efficiency and speed.
Why Not Build a Layer 2?
When asked why MagicBlock chose to build ephemeral rollups instead of a traditional Layer 2 solution, Andrea emphasized the importance of maintaining ecosystem cohesion:
"We don't think and to make much sense in the sense that you're really fragmenting the ecosystem... We love the idea of a single state machine. We love the idea of having everything on the same layer."
By extending Solana's capabilities rather than creating a separate layer, MagicBlock aims to introduce new use cases that can leverage Solana's existing features without fragmenting the ecosystem or requiring complex bridging mechanisms.
The Future of MagicBlock and Solana Gaming
As MagicBlock prepares to release its initial version of ephemeral rollups, Andrea expressed excitement about the lineup of games that will soon be announced. These games will allow users to test ephemeral rollups on the Solana Mainnet, leveraging tokens on Solana while benefiting from the real-time performance capabilities of ephemeral rollups.
The company's focus has been primarily on optimizing the execution environment of the ephemeral validator, with Andrea noting:
"90% of our engineering has been focused on improving the execution environment of the node of the ephemeral validator. We recently published containerized version of the node that waits 47 megabytes, so super lightweight, and at the same time if you run it locally against, you know, Solana node, you'll see that is about 15-20 times faster."
The A16z Accelerator Experience
MagicBlock's participation in the A16z crypto startup accelerator provided valuable insights and resources. Andrea described the experience as deeply foundational for an early-stage startup, offering access to A16z's team of cryptographers, researchers, engineers, marketers, and lawyers.
He also noted A16z's bullishness on games and gaming, reflecting a broader industry trend:
"If you think about it, 2017 Ethereum got clocked through CryptoKitties, a game, and then next cycle 2021, StepN, right, and Axie Infinity. So in sort of both the previous cycle, the best consumer application were games, and so I'm ready to bet that we're gonna see kind of another cycle where we really onboard the next 10 million, 100 million players to a really successful game."
The Current State of the Gaming Industry
While acknowledging that the gaming industry is currently facing challenges, Andrea sees significant opportunities for crypto to disrupt traditional gaming models, particularly in mobile gaming. He points out that the current business model for mobile games is "completely broken," with only about 2% of players actively paying for games.
"There's plenty of opportunity for crypto to completely disrupt that model in terms of... so many levels like payments, discovery, user acquisition, on-chain referrals, like new game genre there are, you know, not possible off-chain," Andrea explains.
Overcoming Perception Challenges
Addressing the potential perception problem of integrating crypto into games, Andrea acknowledges that there has been some skepticism in the past. However, he notes that the situation is improving:
"There's not to say that the perception is completely changed, but it's not definitely has a style as it's used to be. And at the same time, it's also often a matter of terminology."
He suggests that using alternative terms like "digital asset" instead of "NFT" or "forever game" instead of "crypto game" can help overcome initial resistance and encourage users to explore these new experiences.
The Future of On-Chain Gaming
Looking ahead, Andrea expresses optimism about the potential for on-chain gaming to create entirely new experiences and digital worlds. He envisions a future where games can leverage technologies like AR, VR, and AI to generate player-driven content and stories:
"Just so, so many interesting things happening all of a sudden and all together that I cannot not be bullish on on-chain games."
As MagicBlock continues to develop its ephemeral rollup technology and the broader Solana gaming ecosystem evolves, the potential for innovative, fully on-chain gaming experiences grows. With the promise of low-latency, high-performance applications and games, Solana is positioning itself at the forefront of the next generation of blockchain-based entertainment and utility.
The success of projects like MagicBlock could play a crucial role in onboarding millions of new users to the Solana ecosystem, driving adoption and innovation in the blockchain gaming space. As the technology matures and more compelling games come to market, we may see a shift in how players interact with digital assets and virtual worlds, potentially revolutionizing the gaming industry as we know it.
