Astar and Shiden are emerging as pivotal blockchain hubs for decentralized applications (DApps) on Polkadot, integrating EVM and WASM virtual machines to support Layer 2 solutions. Their vision is to evolve into a multichain smart contract platform accommodating diverse virtual machines. This article demystifies their features, scalability solutions, and ecosystem benefits.
Key Features of Astar/Shiden Networks
1. Multichain Smart Contract Hub
Astar/Shiden enables cross-chain smart contract deployment across Ethereum, COSMOS, BSC, and Solana via Polkadot. This interoperability reduces gas fees and enhances transaction speeds, attracting developers with staking rewards.
2. Layer 2 Scalability Solutions
By implementing ZK-Rollup (for security/privacy) and Optimistic Rollup (for transaction validation), Astar/Shiden mitigates Layer 1 congestion and high gas costs.
3. X-VM Technology for EVM-WASM Interoperability
Unique X-VM (Cross-Virtual Machine) technology allows EVM and WASM-based smart contracts to interact seamlessly, broadening development possibilities with languages like Rust and C++.
4. DApp Staking Rewards
Developers earn token rewards through DApp Staking:
- 40% of block rewards go to developers.
- 10% is allocated to staking users.
This incentivizes ecosystem growth while ensuring liquidity.
5. Microsoft Japan Partnership
Microsoft supports Astar/Shiden’s infrastructure development, providing Azure cloud tools and GitHub access via its startup program.
