Altius brings institutional-grade, high-performance execution layer to any blockchain, removing infrastructure complexities so teams can build at scale.

Altius is designed to optimize blockchain performance through a VM-agnostic execution framework that enhances scalability, efficiency, and cross-chain interoperability. By decoupling the execution layer from monolithic network designs, the Altius Stack integrates seamlessly with Layer 1s, Layer 2s, and application-specific chains, providing immediate performance improvements without requiring specialized hardware.

Designed with a modular architecture tailored for a multi-chain future, Altius empowers any blockchain to achieve faster transactions, reduced costs, and enhanced interoperability, futureproofing them for the next generation of on-chain applications.

Altius's core team includes former Managing Partner of Amber Group and a 14-year HFT distributed systems veteran from Hudson River Trading, and is backed by Founders Fund and Pantera Capital: https://www.bloomberg.com/news/articles/2025-02-18/hudson-river-amber-crypto-quant-vets-want-to-take-on-solana

Technical architecture

• Parallel Scalable Storage: Traditional blockchains face state access bottlenecks, increasing latency as network activity grows. Altius partitions data into multiple shards, enabling concurrent read/write operations across nodes via Scalable State Merkle Trie (SSMT). This approach ensures that high-throughput processing can be run on commodity hardwares with reduced costs.
• Instruction-level Parallelism: Rather than executing transactions sequentially, Altius processes them in parallel at resolves conflicts at a more granular level - Altius identifies transaction dependencies at the instruction level by transforming bytecode into a Static Single Assignment format (SSA), only re-executing conflicted instructions instead of the entire transaction.
• Application Code Assessor: The Application Code Assessor (ACA) evaluates smart contract efficiency and rewards developers for optimizing execution throughput. By incentivizing contract designs that reduce conflicts and maximize parallel execution, Altius ensures that dApps remain scalable and cost-efficient as blockchain adoption grows.

Alpha release

We have launched an EVM implementation with the altius-revm parallel execution engine and altius-reth, achieving a 4× improvement over sequential execution and proportional gains in gas-per-second throughput.

Key highlights:

• 4× faster execution: processes 100k ERC20 transfers in 905ms (compared to 3.38s sequentially)
• altius-reth has integrated Ethereum Engine API support, enabling the first parallel execution engine capable of producing real mainnet blocks
• Production-ready: tested with real-world patterns (ETH/ERC20 transfers, chained/m2m/o2m transactions)
• SSMT (Scalable State Merkle Trie) in beta running in altius-reth 1.7.0
• Docker support

To break it down further, we have run benchmarks under various scenarios:

🔹 Complex DeFi workloads (Uniswap-style transactions)

🔹 On commodity hardware (no high-end tuning)

The results demonstrates that the Altius execution engine for Ethereum-compatible systems combines speed, determinism, and scalability across any workload, from ERC20 transfers to the most complex DeFi protocols.

Benchmark Results

✅ Same final state root across all modes → deterministic correctness preserved
