Zilliqa 2.0 marks a critical upgrade as the Zilliqa network enters a new phase, with its core focus on fully transitioning network consensus and security mechanisms to a permissionless Delegated Proof-of-Stake (PoS) architecture. In this version, staking is no longer merely an auxiliary reward mechanism, but becomes a foundational component of network operation and security. ZIL holders and validators will directly participate in block production and the consensus process, jointly maintaining the stable operation of the network.
As blockchain applications continue to scale, demands for transaction efficiency, finality speed, energy efficiency, and decentralization have steadily increased, exposing the limitations of traditional PoW-based architectures. By introducing PoS consensus, permissionless validator participation, a dual-layer staking contract design, and clearly defined reward and penalty rules, Zilliqa 2.0 lowers node operation barriers and energy consumption while ensuring that staked assets genuinely assume responsibility for network security. This shifts Zilliqa’s security model from one driven by computational power to one jointly supported by economic incentives and validator behavior.
This article systematically introduces the core changes brought by Zilliqa 2.0, including why the network is transitioning from PoW to PoS, how the legacy SSN staking mechanism operates and its limitations, the design logic of the new permissionless staking architecture, validator reward and penalty mechanisms, and the differences and use cases of liquid and non-liquid staking. It further explains how users, validators, and node operators can participate and migrate after the mainnet upgrade, helping readers fully understand how Zilliqa 2.0 reshapes network security architecture and the role and value ZIL plays in this new phase.
Overview of Zilliqa
Zilliqa is a high-performance Layer 1 blockchain designed with scalability as its core objective. Developed by a Singapore-based team, it aims to resolve the structural limitations of traditional blockchains in transaction speed and throughput at the base protocol level. As one of the earliest blockchains to natively introduce sharding on mainnet, Zilliqa restructures blockchain operations by splitting the entire network into multiple shards that can operate in parallel, enabling transactions to be processed simultaneously rather than relying on full-network broadcast mechanisms.
As blockchains increasingly become foundational infrastructure for finance and digital applications, Zilliqa is built on the core assumption that “node scale equals performance capacity.” By combining native sharding architecture, a hybrid consensus mechanism, and immediate finality design, Zilliqa achieves the ability to process thousands of transactions per second, providing predictable and stable base-layer performance for high-frequency trading, enterprise applications, and compliance-oriented scenarios, while establishing an engineering-driven position within the public blockchain scalability landscape.

As the Zilliqa 2.0 network prepares for official launch, the overall blockchain architecture will undergo a key transformation. The most significant change is the comprehensive upgrade of the staking mechanism.
The new version introduces permissionless Delegated Proof-of-Stake (PoS), replacing the previous PoW-based operational model. This not only changes how nodes are produced, but also makes ZIL staking a genuine component of network security.
Why transition from PoW to PoS?
The architectural shift in Zilliqa 2.0 has clear objectives:
- Improve transaction processing efficiency and finality speed
- Reduce node operating costs and energy consumption
- Enhance overall network decentralization
- Enable staked assets to actively participate in consensus security
This means that future Zilliqa network security will no longer rely on large-scale computational hardware, but will instead be jointly maintained by validators who hold and stake ZIL.
Review of the legacy Zilliqa staking model
In the current Zilliqa network, staking primarily revolves around Staked Seed Nodes (SSNs). These nodes are responsible for storing historical data, providing API services, and earning a share of block rewards through staking.
Key characteristics of this model include:
- SSN nodes must stake at least 10 million ZIL to qualify
- Rewards are distributed based on node availability and performance
- Regular users can delegate ZIL to SSNs to earn rewards
- Unstaking requires a 14-day unlocking period
- If a node’s staked amount falls below the threshold, it stops receiving rewards
This mechanism operates as a permissioned system, where SSNs must first be registered through official contracts to become valid nodes.
The new staking architecture in Zilliqa 2.0
In Zilliqa 2.0, staking officially becomes the core of network consensus, adopting a permissionless, dual-layer structure:
- Layer 1: Deposit Contract Anyone meeting the minimum requirement (10 million ZIL) can directly become a validator.
- Layer 2: Delegation Contracts Validators can deploy their own delegation contracts, allowing other users to delegate ZIL into their staking pools.
This design removes the need for official approval for validators, opening participation to all eligible actors.
How are validator rewards distributed?
Zilliqa 2.0 distributes rewards on a per-epoch basis (3,600 blocks), with a total of 51,000 ZIL issued per epoch:
- 50% distributed based on the number of successfully proposed blocks
- 50% distributed based on voting participation, counting only the fastest two-thirds of validators
If a validator maintains an average efficiency of one block per second, a full epoch’s rewards can be completed in approximately one hour.
Design of liquid and non-liquid staking
The Zilliqa team also provides two reference delegation contracts:
- Non-liquid staking version: Users must manually claim rewards, and assets are locked during the staking period.
- Liquid staking version: Issues non-rebasing liquid tokens whose price increases as rewards accumulate.
Both contracts are developed in Solidity and undergo full audits prior to public release.
Security mechanisms and penalty design
To ensure PoS network stability, Zilliqa 2.0 introduces two penalty mechanisms:
- Slashing: Deduction of staked assets for security violations such as double signing
- Jailing: Temporary isolation of nodes that are offline for extended periods or miss block production
A 14-day unlocking period is retained to prevent malicious nodes from immediately withdrawing funds after misbehavior.
Staking access points and migration process
Zilliqa will launch a new EVM-based staking portal allowing users to:
- View the validator list
- Delegate and manage staked assets
- Claim rewards and adjust node settings
Users currently staking through SSNs must manually migrate their ZIL to the new contracts after the mainnet upgrade.
Next steps for validators and node operators
Once Zilliqa 2.0 goes live, node operators must deploy new nodes and stake into the Deposit Contract. They may also deploy their own delegation contracts to establish staking pools. Official reference contracts and operational guides will be provided. All systems will first be launched on the proto-mainnet testnet, allowing the community to familiarize itself with the workflow in advance.
Final thoughts
Zilliqa 2.0 offers a fundamental reconfiguration of the network’s operational logic. The staking mechanism shifts from a reward-oriented auxiliary function to a core component directly involved in consensus and security. This also signifies a transformation in the role of ZIL holders, from passive users to active participants in network governance and security. With the full rollout of permissionless validators, liquid staking, and penalty mechanisms, Zilliqa officially enters a new PoS-based phase.
