Artela

Aspect Programming is a core innovation that allows developers to inject custom logic, called Aspects, into a smart contract's execution lifecycle. This enables cross-contract functionalities and runtime extensions without modifying the original contract code.

• Pre/Post-Execution Hooks: Intercept and augment transaction flows.
• Native Extensions: Add features like automated transaction batching or custom fee logic.

The network dynamically scales computational resources by allowing Aspects to execute on dedicated, parallelizable Elastic Blocks. This separates core transaction execution from extended logic, preventing congestion and enabling complex dApps.

• Horizontal Scalability: Add more nodes to increase Aspect processing power.
• Resource Isolation: Prevents one intensive Aspect from slowing down the entire network.

Artela maintains full compatibility with the Ethereum Virtual Machine (EVM) and its tooling (MetaMask, Hardhat), while extending its capabilities. Developers can deploy standard Solidity/Vyper contracts and enhance them with native features via Aspects.

• Seamless Migration: Existing EVM dApps can port with minimal changes.
• Extended Opcodes: New precompiles and instructions enable Aspect interactions.

The protocol abstracts gas payment, allowing users to pay transaction fees in any token supported by the network, not just the native ART token. This is enabled by a Gas Aspect that handles fee delegation and conversion.

• Improved UX: Users don't need to hold multiple tokens for gas.
• Sponsored Transactions: DApps can subsidize fees for their users.

Security is enforced through a deterministic and isolated execution model for Aspects. The Aspect Virtual Machine (AVM) runs extensions with clearly defined permissions and resource limits, minimizing attack surfaces.

• Deterministic Verification: Aspects are verified by all network validators.
• Sandboxed Execution: Limits the blast radius of a faulty or malicious Aspect.

Complex dApp logic is decomposed into modular, reusable Aspects that can be composed across different applications. This creates a marketplace of shared functionalities, such as decentralized oracles, keeper networks, or privacy layers.

• Composability: Plug-and-play modules for common Web3 needs.
• Developer Ecosystem: Incentivizes creation of open-source, reusable Aspects.

Artela's core innovation is Aspect Programming, a framework for building native extensions (Aspects) that can be injected into the transaction lifecycle. This allows developers to add custom logic—like pre/post-execution hooks, security policies, or gas optimizations—directly into the blockchain's execution layer without forking the core protocol.

• Key Components: Aspect Code, Join Points (e.g., PreTxExecute, PostTxExecute), and the Aspect Virtual Machine (AVM).
• Parallel Execution: Aspects are designed to run in parallel with transaction execution, minimizing latency overhead.
• Use Case: Building a native account abstraction wallet that validates complex social recovery rules before a transaction is finalized.

The network uses an Elastic Computing model to scale transaction processing horizontally. By separating the execution of core transactions from Aspect logic, Artela can dynamically allocate resources.

• Vertical Scaling: The main EVM execution layer handles standard smart contract logic.
• Horizontal Scaling: The Aspect layer scales out by adding more nodes to the Aspect Virtual Machine (AVM) network to process custom extensions.
• Benefit: This architecture prevents custom extension logic from congesting the base layer, maintaining high throughput for dApps with complex, on-chain automation.

Aspects enable the creation of native security modules that are more powerful and efficient than smart contract-based solutions. These modules operate at the protocol level, offering deeper integration and protection.

• Real-time Monitoring: An Aspect can scan every transaction for malicious patterns (e.g., sandwich attacks) before it is included in a block.
• Pre-Execution Hooks: Enforce custom security policies, like multi-signature requirements or spending limits, at the transaction validation stage.
• Example: A DEX can deploy an Aspect that automatically blacklists addresses associated with known exploits, providing a native layer of protection for all its liquidity pools.

Developers can build native automation services and high-performance oracles directly into the chain's execution flow, reducing reliance on external, potentially unreliable systems.

• Native Keepers: Aspects can listen for on-chain conditions and trigger transactions (e.g., liquidations, limit orders) without an external network.
• Low-Latency Data Feeds: An Aspect can be programmed to fetch, verify, and write data (like price feeds) at specific Join Points, ensuring data is available within the same block.
• Advantage: Eliminates the latency, cost, and trust assumptions associated with bridging data from Layer-2 oracles or off-chain services.

Aspects allow dApps to define custom transaction types and validation rules, enabling functionality that is impossible or inefficient with standard smart contracts alone.

• Programmable Gas Models: An Aspect can implement a gas sponsorship mechanism where a protocol pays for its users' transactions.
• Complex Authorization: Define transaction logic that requires proofs from other chains or verifiable credentials.
• Use Case: A gaming dApp can create a "session key" transaction type validated by an Aspect, allowing players to perform multiple in-game actions with a single signature for a set period.

Aspects can be designed to facilitate secure cross-chain communication by acting as a lightweight verification layer within Artela's own consensus.

• Light Client Verification: An Aspect can contain the logic to verify block headers or state proofs from other chains (e.g., Ethereum, Cosmos).
• Cross-Chain Messaging: Upon verification, the Aspect can trigger actions on Artela, enabling trust-minimized bridging and composability.
• Architecture: This moves the complexity of interoperability into a scalable, parallelizable extension, rather than burdening the core EVM runtime.

Artela's core innovation is Aspect Programming, a native extension mechanism that allows developers to inject custom logic into the blockchain's execution layer. Aspects are modular, interoperable components that can modify transaction flow, add pre/post-execution hooks, and implement cross-chain logic without forking the core protocol. This enables features like native account abstraction, automated transaction batching, and enhanced security modules directly at the chain level.

The network introduces Elastic Block Space, a scalable architecture that separates transaction execution into multiple parallel lanes. Key components:

• Baseline EVM: Provides standard, fully EVM-compatible execution.
• Aspect VM: A secure, isolated runtime for executing custom Aspect logic.
• Elastic Computing: Allows developers to deploy resource-intensive Aspects (e.g., for AI or complex computations) by bidding for additional block space, enabling horizontal scalability beyond the baseline chain limits.

Artela provides a comprehensive suite of tools for building Aspect-Extended dApps:

• Artela CLI: For project scaffolding, compilation, and deployment of both smart contracts and Aspects.
• Aspect IDE: Development environment with templates and debugging tools.
• Testnet & Faucet: The Artela Testnet for development and a faucet for obtaining testnet tokens.
• Block Explorer: A network explorer to inspect blocks, transactions, and Aspect deployments.

A core innovation of Artela that allows developers to inject custom logic (Aspects) into a blockchain's native execution flow. Think of it as a smart contract middleware that can intercept and extend transactions.

• Pre-Execution & Post-Execution Hooks: Inject logic before or after a transaction's main execution.
• Cross-Contract Composability: Aspects can read/write state across multiple contracts atomically.
• Native Extension: Unlike sidechains or L2s, Aspects run as part of the base layer's consensus, inheriting its security.

Artela's scaling mechanism that allows the network to dynamically allocate computational resources by adding Elastic Blocks alongside the main block.

• Parallel Execution: Elastic Blocks enable parallel transaction processing, increasing throughput.
• Resource Isolation: Custom Aspects and complex computations can be offloaded to Elastic Blocks, preventing them from congesting the core layer.
• Deterministic Finality: Results from Elastic Blocks are verified and settled on the main chain, maintaining security.

The secure, sandboxed runtime environment where Aspects are executed. It is separate from the main EVM but integrated at the protocol level.

• WASM-Based: Enables developers to write Aspects in multiple languages (Rust, Go, C++).
• Deterministic Execution: Guarantees consistent results across all network nodes.
• Controlled Access: Provides Aspects with secure, granular access to blockchain state and transaction context.

Artela's enhanced execution layer that combines the standard Ethereum Virtual Machine (EVM) with the Aspect VM to create a more powerful runtime.

• Backward Compatibility: Fully supports all existing EVM smart contracts and tooling.
• Extended Functionality: Allows EVM contracts to be seamlessly augmented by Aspects written in other languages.
• Unified State: Both VMs operate on a single, coherent global state, enabling deep interoperability between components.
