MagicBlock Labs, a 16-person team with roots in AI research and low-level systems engineering, presented their vision for bringing real-time elastic compute to Solana. Their technology, called ephemeral rollups, has already processed over a billion transactions through their MagicNet canary network, with 250,000 ephemeral sessions across 11,000 unique active addresses.

The core innovation enables Solana developers to delegate arbitrary accounts into ultra-fast SVM (Solana Virtual Machine) instances on demand. Think of it as multi-threading for blockchain programs—developers can spin up parallel execution environments, process state transitions at lightning speed, and then commit the results back to Solana's main chain. This architecture maintains full composability with existing Solana programs while achieving latencies as low as 10 milliseconds.

CEO Andrea Fortugno emphasized that fully on-chain applications offer properties impossible with traditional servers: verifiability, DeFi composability, censorship resistance, and permissionless access. Perhaps most compelling for developers, this approach unlocks new revenue opportunities—taking fees on volume, earning yield on platform funds through DeFi integrations, and more.

The four new upgrades announced signal MagicBlock's push toward mainnet: a lightweight scheduler delivering 50,000 TPS on commodity hardware, native account compression reducing storage costs by up to 200x, improved cloning pipelines for better Solana synchronization, and deployment within military-grade data centers for an additional physical security layer.

Key Points

Ephemeral Rollups: Multi-Threading for Solana

MagicBlock's foundational technology allows developers to add a single instruction to their existing on-chain programs that delegates accounts to high-speed SVM instances. When triggered, a router pings available nodes globally, clones the relevant state on demand, and enables blazing-fast state transitions within these isolated environments.

The key differentiator is maintaining composability with Solana throughout the process. Developers can commit state diffs back to the main chain, execute cross-program invocations (CPI) with other programs, and bundle transactions that execute atomically or not at all. When the processing job completes, accounts simply undelegate and return their final state to Solana. This creates an architecture where Solana acts as the "main thread" while ephemeral rollups function as parallel worker threads handling compute-intensive tasks.

Customizable Runtimes and Privacy Features

Beyond raw performance, MagicBlock enables applications to choose their preferred runtime characteristics. Privacy stands out as a particularly powerful plugin—accounts delegated to SVM instances running inside Intel TDX trusted execution environments can achieve private state transitions, opening doors for applications requiring confidentiality.

The platform also supports real-time oracle price streams and verifiable random functions (VRF) without requiring separate on-chain transactions for each update. This is critical for high-throughput applications like trading platforms and games that need probably fair randomness without the overhead of constant blockchain writes. Fine-grained programmable access control allows developers to specify exactly who can read or write delegated state, with options like geofencing to prevent sanctioned countries from interacting with private applications.

Trading and Financial Applications

For trading platforms like Flash Trade, Archer, and Mac Speed, 10-millisecond latency isn't just a nice-to-have—it's transformational. Market makers operating on a first-come-first-serve basis can quote tighter spreads because they can adjust positions instantly when market volatility increases. Colocation ensures optimal latency for professional traders.

The trusted execution environment capabilities enable private auctions and concentrated liquidity bonding curves (CLBs) with interesting new dynamics. Since everything remains SVM-based, these private operations can still compose with the broader Solana ecosystem through atomic bundles that either execute completely or revert entirely.

Gaming and Consumer Applications

Fully on-chain games benefit enormously from feeless transactions during gameplay—the user experience feels like Web2 while maintaining access to native USDC and other tokens. New users can onboard without understanding gas fees, yet they're interacting with genuine blockchain-based assets.

VRF integration is particularly crucial for gaming, ensuring fairness in randomized outcomes. Players can trust that loot drops, card draws, or battle results are genuinely random and verifiable, not manipulated by game operators. This transparency, combined with smooth performance, creates gaming experiences that leverage blockchain's unique properties without sacrificing user experience.

The Four Major Protocol Upgrades

MagicBlock's new lightweight scheduler represents a significant engineering achievement—50,000 transactions per second on commodity hardware. Because node requirements are much lower than standard validators, this scheduler can run as a sidecar to existing Solana validators, dramatically expanding what's possible without requiring expensive infrastructure investments.

The partnership with Light Protocol brings native account compression directly into the ephemeral rollup architecture. This delivers up to 200x reduction in storage costs while allowing accounts to be decompressed within the rollup for normal interaction—combining cost efficiency with full functionality.

The improved cloning pipeline keeps ephemeral rollups synchronized with Solana more reliably and quickly. New streaming support adds redundancy, allowing users and validators to independently verify state transitions happening within specific ephemeral rollups. This additional validation layer strengthens the security model considerably.

Finally, deploying trusted execution environment nodes within military-grade data centers adds physical security on top of hardware enclave protections. This defense-in-depth approach addresses concerns about physical attacks on sensitive infrastructure.

Path to Decentralized Mainnet

MagicBlock's vision positions them as a decentralized co-processing layer for transactions that currently can't run on Solana and instead rely on centralized AWS servers. Applications can either host their own nodes or rely on existing node operators who stake capital and face slashing penalties for misbehavior.

This economic security model, combined with Solana-native development workflows and Web2-like storage and execution costs, creates a compelling alternative to traditional centralized backends. The entire codebase remains open source, with active development visible on GitHub and community engagement through Discord.

Questions Answered

What are ephemeral rollups and how do they work?

Ephemeral rollups are temporary, high-speed SVM instances that process blockchain transactions in parallel to Solana's main chain. When a developer triggers a delegation instruction, a global router identifies available nodes, clones the relevant account state, and allows rapid state transitions within the isolated environment. The results can be committed back to Solana through state diffs or cross-program invocations. Think of it as spinning up temporary compute workers that handle intensive processing, then merge their work back into the main blockchain when finished.

Why would developers want to build fully on-chain applications?

Building fully on-chain provides properties impossible with traditional servers: verifiability of all application logic, composability with DeFi protocols, censorship resistance, and permissionless access. Beyond philosophical benefits, there are concrete revenue opportunities—developers can take fees on transaction volume, earn yield by deploying platform funds through DeFi integrations like Kamino, and create new monetization models that don't exist in Web2. Applications become unstoppable since no single entity can shut them down.

How does MagicBlock achieve privacy for blockchain transactions?

Privacy is implemented through trusted execution environments, specifically Intel TDX enclaves. When accounts are delegated to SVM instances running inside these hardware-protected environments, state transitions become private—the computation happens in a secure enclave that even the node operator cannot inspect. Additionally, fine-grained programmable access control lets developers specify exactly who can read or write delegated state, with options for geofencing to comply with regulations.

What makes the new 50,000 TPS scheduler significant?

The new scheduler achieves this throughput on commodity hardware, not specialized expensive infrastructure. It can run as a sidecar to existing Solana validators, meaning node operators don't need entirely new setups. This dramatically lowers the barrier to providing high-performance compute for applications that need it, enabling use cases that were previously impractical due to performance limitations or infrastructure costs.

How does account compression reduce costs by 200x?

Through a partnership with Light Protocol, MagicBlock integrates native account compression into their ephemeral rollup architecture. Compressed accounts take up far less storage on-chain—up to 200 times less—while remaining fully functional within the rollup environment where they can be decompressed for normal interaction. This makes it economically viable to build applications with many accounts that would otherwise be prohibitively expensive to maintain on-chain.

What security measures protect the network?

MagicBlock employs multiple security layers: trusted execution environments provide hardware-level protection for sensitive operations, economic incentives through staking and slashing penalties ensure node operator honesty, streaming support allows independent validation of state transitions, and some nodes are deployed in military-grade data centers adding physical security. This defense-in-depth approach addresses attack vectors at multiple levels from software vulnerabilities to physical hardware access.
