Polana is a next-generation blockchain execution environment that integrates Solana’s developer-oriented architecture with the highly parallel RISC V–based execution capabilities of the JAM Protocol. Designed to address key limitations in blockchain scalability, Polana introduces continuous execution, high throughput, and cross-ecosystem interoperability for decentralized applications.
Continuous Execution at Scale
Polana introduces a novel execution model referred to as continuous execution. In contrast to conventional blockchains, which process transactions in discrete units, Polana allows smart contracts to retain state across blocks and autonomously respond to on-chain events. This model enables the development of applications that are:
- Capable of maintaining autonomous state
- Structured around event-driven logic
- Designed for efficiency and responsiveness
This paradigm facilitates the creation of advanced use cases such as algorithmic trading systems, dynamic non-fungible tokens (NFTs), autonomous agents, and liquidity mechanisms that adjust in real time to market dynamics.
Polana Performance and Scalability
Polana is engineered for enterprise-level performance, supporting up to:
- One million transactions per second for simple operations
- Two hundred fifty thousand transactions per second for complex smart contract executions
- Scalability into the multi-million transactions per second range with the expansion of the JAM Grid
By adapting Solana’s account-based model to JAM’s multicore, stateless computational environment, Polana maintains developer familiarity while unlocking horizontal scalability across a distributed network.
Compatibility and Developer Experience
Polana ensures seamless integration with existing Solana infrastructure and tools.
For Developers
- Maintains an identical programming model, requiring no changes to existing Solana code
- Supports native development tools including Anchor, Solana CLI, and Solang
- Offers flexible execution strategies through Solana bytecode interpretation, transpilation to intermediate formats, or native compilation to JAM’s execution format
For Users
- Compatible with widely used Solana wallets including Phantom, Backpack, and Solflare
- Allows continued use of current Solana wallet addresses
- Removes the need for traditional cross-chain bridging by enabling direct interaction with JAM-based services
This interoperability preserves the user and developer experience while extending the capabilities of Solana applications into the JAM environment.
Technical Architecture
Polana is built upon the JAM Protocol, an execution model composed of two main stages:
- A Join phase that performs parallel, stateless computation across multiple cores
- An Accumulate phase that commits processed results to a shared on-chain state
This architecture is implemented using the Polkadot Virtual Machine and leverages the open-source RISC V instruction set for optimal performance. The initial configuration includes approximately three hundred forty one cores, enabling high-frequency data processing without compromising decentralization or hardware accessibility.
Cross-Ecosystem Integration via pSOL
To facilitate liquidity and application-level interoperability, Polana introduces pSOL, a JAM-native representation of SOL. This asset expands the utility of Solana’s liquidity within the Polkadot ecosystem and supports the following objectives:
- Aggregation of liquidity between Solana and Polkadot applications
- Extension of decentralized finance and trading use cases
- Integration of Solana-based assets into Polkadot’s security model
- Collaboration across two of the most active developer communities in the blockchain sector
Strategic Applications
Polana’s architecture enables use cases that require both computational intensity and autonomy:
- High-frequency trading strategies that demand microsecond-level latency and persistent execution
- Blockchain-based gaming and metaverse applications with on-chain logic and dynamic asset evolution
- Institutional decentralized finance platforms that adhere to regulatory and performance requirements
- Cross-chain decentralized applications that leverage unified liquidity and robust infrastructure
Development Roadmap
The implementation of Polana is proceeding through a structured development plan:
- Completion of specifications and requirements for Solana compatibility
- Ongoing development of a compiler toolchain targeting JAM’s architecture
- Construction of a runtime environment that supports Solana’s execution semantics
- Deployment of developer tools and client libraries
- Launch of a mainnet-ready production environment for continuous execution applications
Conclusion
Polana represents a substantial advancement in blockchain infrastructure. By merging Solana’s intuitive and high-performance development experience with the JAM Protocol’s scalable execution framework, it achieves levels of performance and flexibility necessary for future-facing Web3 applications. The introduction of continuous execution, compatibility with existing developer ecosystems, and cross-chain functionality positions Polana as a critical component in the evolution of decentralized computing.
Through its innovative design, Polana enables a new category of decentralized applications characterized by autonomy, real-time responsiveness, and institutional-grade scalability. This positions the project at the forefront of infrastructure development in the blockchain domain.
