High-Performance Blockchains: Pushing the Limits

.

This new approach decouples the execution layer from the consensus layer, aiming to deliver Web2-level performance for decentralized applications (dApps). Instead of introducing yet another general-purpose blockchain, Altius is offering execution as a service to power purpose-built chains – boosting speed and scalability without sacrificing decentralization. This strategy also tackles the notorious “state bloat” problem that plagues many high-performance chains relying on expensive, centralized hardware.

Addressing the Blockchain Scaling Trilemma and Current Limitations

To build high-performance blockchains, Altius Labs is opting for a technically sophisticated innovation: they're creating an execution layer as a service rather than building yet another new blockchain. This approach stems from the belief that the blockchain space no longer needs general-purpose chains but rather purpose-built chains, similar to various applications on a smartphone.

In the current blockchain landscape, scaling blockchains often comes with trade-offs, a problem known as the Trilemma, where one must choose between speed, security, or decentralization. Many high-performance chains in the past have sacrificed decentralization for speed and security, relying on highly specialized or efficient sequencers and validators. This often requires expensive, high-spec hardware or centralized hyperscalers, which exacerbates the State Bloat problem, putting active chains at risk of running out of memory even with the most powerful machines.

Altius Labs is committed to overcoming these challenges by guaranteeing the decentralization of smart contract execution while simultaneously delivering exceptional performance to the chain system.

Key Technical Innovations Driving Performance

Altius's architecture introduces several core innovations:

• VM-Agnostic Modular Execution Layer: Altius is building a layer that separates high-performance execution from the blockchain stack, making it compatible with any chain. This enhances existing Virtual Machines (VMs) like EVM, SVM, and MoveVM, rather than creating a new VM or forcing developers to learn new languages.

• Deterministic Concurrent Control at Opcode Level: This is a crucial technical innovation. Unlike leading Layer 2s (L2s) and existing VMs (e.g., Sealevel in SVM or BlockSTM in MoveVM) that manage parallelism at the transaction level, Altius employs deterministic concurrent control at the opcode level. This more granular approach means that when conflicts arise during optimistic parallel execution, Altius only re-executes the conflicting opcodes within a transaction, rather than the entire transaction.

To draw a comparison, it's like two passengers sharing a ride to different destinations, dropping one off midway instead of requiring separate cars for each due to a perceived conflict in destinations. Annabelle Huang also gave the example of NFT minting, where multiple 'N+1' increments, generally considered conflicting at a transaction level, can be efficiently processed in parallel by only re-executing the last instruction, or by splitting the count across multiple machines. This leads to superior parallel performance and significant savings in re-execution costs and gas fees.

Sharded Database Architecture: Altius addresses State Bloat through a sharded database design that distributes the state across multiple standard nodes, enabling high-performance execution on commodity hardware, such as standard AWS nodes. This allows for more freedom in node operation, similar to the early days of Bitcoin/Ethereum where nodes could run on laptops, a significant shift from current infrastructure requiring hyperscalers. This scalability allows for adding more machines to resolve State Bloat as chains become more active.

Expected Performance Targets

Altius's performance goals are highly ambitious. While leading L2s like Base currently operate at approximately 50 million Gas per second and aim for 250 million Gas per second, Altius enables an immediate leap to 1-2 Giga-Gas per second, representing a 10-20x improvement over current infrastructure. In terms of throughput and latency, Altius can enable Solana-level performance or faster for existing EVM chains and other VMs, with the ultimate goal of achieving Visa-level payment processing speeds or even faster.

Developer Experience and Future Vision: Open Execution Network (OEN)

Altius is designed to seamlessly integrate with existing developer workflows. Smart contract developers can continue writing code in Solidity/Rust, as execution optimization happens at the bytecode level. Altius introduces a Transpiler architecture built in Rust, which interprets multiple VM languages (EVM, SVM, Move). Once implemented for one VM, extending to others mostly requires only considering different opcode sets, not entirely new code, making it easy to scale across the fragmented blockchain development landscape.

Altius's long-term vision is the Open Execution Network (OEN). OEN will enable dynamic load balancing across chains, meaning if one chain experiences congestion (e.g., during an NFT mint or airdrop), idle resources from other chains can be dynamically allocated to help handle the load. This horizontal integration can also enable native cross-chain interoperability at the execution layer, eliminating the need to rely on bridges and their associated risks. Transactions can be composed across chains without manual inventory management, addressing current manual and risky cross-chain swap processes.

OEN aims to decentralize the execution network, making it accessible to anyone with commodity hardware, similar to what Netflix or AWS do for load management. Importantly, Altius focuses solely on optimizing the execution layer and is not involved with the Consensus layer, Data Availability, or Settlement. By accelerating execution and communication with the Consensus layer, Altius will enable chains to reach consensus much faster. This horizontal scalability of OEN means that adding more participants will enable more parallel processing, theoretically allowing for continuous transaction scaling.

Transformative Use Cases

By unlocking this level of performance and interoperability, Altius opens the door to new possibilities for decentralized applications and blockchain infrastructure. Potential use cases include:

• Decentralized Trading Infrastructure: Full on-chain order books that can compete with Centralized Exchanges (CEXs) and institutional trading infrastructure allowing for customization like permissioned access or KYC.

• Gaming: Games that process player actions in true parallel, where simultaneous player movements or interactions in the background can be processed in parallel, significantly improving the gaming experience.

• Visa-Level Payment Processing: Enabling real-world assets and on-chain payments at speeds comparable to or faster than Visa or MasterCard, building on existing developments by companies like Stripe in Stablecoins.

• Custom App Chains: Existing decentralized applications (dApps) will be able to leverage Altius's stack to build their own custom App Chains while maintaining Solana-level performance without needing extensive expertise in app development.

Investment and Team Qualifications

Altius Labs successfully raised $11 million in pre-seed funding from leading investors such as Founders Fund and Pantera. This validates the infrastructure investment thesis, signaling investor conviction in addressing significant gaps in the blockchain space and the importance of a long-term vision. Annabelle Huang highlights the team's strong credentials, including her Co-founder and CTO's 14 years of experience at Hudson River Trading, a top High-Frequency Trading (HFT) firm, bringing crucial HFT expertise to blockchain execution.

Roadmap and Engagement

Altius Labs is in the early stages of development. Their Beta EVM implementation is slated for Q3 2025 with their first Design Partner. Expansion to other VMs (beyond EVM) is planned for later this year, aiming to bring their technology to a wider ecosystem.

For those interested in participating, Altius encourages blockchain and dApp developers exploring App Chains to reach out for potential collaborations.
