Zilliqa review
An open-source layer-1 with Scilla, EVM and customizable x-shards.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Zilliqa is an open-source public layer-1 blockchain for builders creating applications that need Scilla or EVM execution, including Solidity smart contracts. Its direction toward credentialed infrastructure for institutional finance adds a mediation layer that checks whether counterparties are permitted to transact before settlement. The network combines staking and validator tooling with customizable x-shards, while public RPC APIs, faucets, block explorers and SDKs support development. Teams evaluating it should consider both the contract environment they want and whether mediation fits their transaction flow.
A notable part of the architecture is the range of execution and consensus options. The main network uses Proof-of-Stake validation with Pipelined Fast-HotStuff, while x-shards can use Proof-of-Authority. Zilliqa also supports cross-chain communication between x-shards, the mainnet and EVM chains. That flexibility may suit teams designing for distinct execution environments, but it means a builder needs to decide how the chosen shard, consensus option and contract language fit together. Developers can use SDKs for Rust, Go, Java, JavaScript/TypeScript and Python; MetaMask is the named wallet integration.
Zilliqa is open source, and the published product details describe APIs, explorers, validator-node setup and delegated staking rather than a managed operating service. That makes it a stronger fit for teams prepared to work with blockchain infrastructure and node participation than for buyers seeking a turnkey managed chain. The credential-checking mediation model is especially relevant to projects whose transactions need permission checks before settlement; applications that do not need that model may find the added layer less aligned with their design. Choose Zilliqa when its Scilla and EVM options, shard architecture and mediation direction match the application; look elsewhere if managed operations are a central requirement.
Zilliqa pros and cons
- Where it wins
- Supports both Scilla contracts and EVM execution with Solidity.
- Offers customizable x-shards with cross-chain communication.
- Provides RPC APIs, explorers and SDKs in five languages.
- Where it doesn't
- The mediation layer checks credentials before settlement.
- Builders must choose between Scilla and EVM/Solidity contract paths.
- Validator-node setup and delegated staking require network-level involvement.
