What is Zilliqa?

Zilliqa (ZIL) is a Layer 1 blockchain designed to tackle the scalability challenge, which refers to the need for a cryptocurrency platform capable of processing a high volume of transactions rapidly. Serving as a smart contract platform, Zilliqa enables the development of decentralized applications (dApps) and tokens within its blockchain infrastructure.

Who Founded Zilliqa?

First launched in 2017, Zilliqa was founded by a group of researchers from the National University of Singapore (NUS) consisting of Xinshu Dong, Yaoqi Jia, Amrit Kumar, and Prateek Saxena. After its launch in 2017, the testnet was brought online in March 2018 with a mainnet launch in June 2019.

Zilliqa’s founders saw great potential in blockchain technology but recognized scalability as a significant barrier. As a result, Zilliqa was designed to be a transformative platform capable of supporting thousands of transactions processed in seconds. This scalability solution is achieved through sharding technology. In addition, to ensure the security of its network, Zilliqa uses a consensus mechanism that combines Proof of Work (PoW) and Practical Byzantine Fault Tolerance (PBFT).

How Does Zilliqa’s Works?

The Zilliqa network consists of two main pillars. The first pillar is transaction processing using sharding technology. The second pillar in Zilliqa is the PoW and PBFT consensus mechanism.


Sharding is a process that divides the network of blockchain nodes into several different groups, called shard chains. For example, 1000 Zilliqa nodes would divide the network into 10 shards, each consisting of 100 nodes. Each shard processes a small portion of transactions simultaneously in parallel with other shards, creating what is known as microblocks.

These microblocks are then combined into a transaction block by the directory service nodes (DS nodes) to form a complete block. If each shard can process 10 transactions per second, then all shards together can process 100 transactions.

For a visualization of the sharding process, you can watch the following video

To put this in perspective, if six shards, each with a total of 3600 nodes, all of the shards on the Zilliqa network together would process approximately 2828 transactions per second. In contrast, Bitcoin (BTC) can only process 7 transactions per second and Ethereum (ETH) can process 15 transactions per second. However, Visa and MasterCard can process an average of 8000 transactions per second.

Practical Byzantine Fault Tolerance (PBFT)

The second pillar within the Zilliqa network is a modification of the PoW consensus protocol with PBFT. This modification is claimed to save mining costs, including the verification and validation of blockchain transactions.

Practical Byzantine Fault Tolerance (PBFT) is a system capable of avoiding failures caused by the Byzantine General Problem. PBFT is at the core of Zilliqa for implementing governance mechanisms that can keep distributed computer networks in sync. In short, a BFT system can continue to operate even if some nodes fail.

For nodes that can operate the blockchain and vote, the first thing they do is stake ZIL tokens. Anyone with ZIL tokens can operate the network. So, the use of PBFT in the operation of the network is to complicate fraudulent or fake transactions on other nodes. In practice, all nodes must agree on the validity of the new block before it is added. Then, each node receives a small portion of the block reward.

The Zilliqa team claims that modifying PoW and PBFT creates a secure mechanism and allows mining with lower computational costs.

The Advantages of Zilliqa

In addition to sharding and modifying PBFT with PoW consensus, the Zilliqa network includes a smart contract layer that provides many features that make it easy to develop and write smart contract programs.

In practice, however, Zilliqa does not use the term “smart contract” directly but instead uses its own intermediate-level smart contract programming language developed by Zilliqa, known as Scilla (Smart Contract Intermediate-Level Language). Scilla is designed as a programming language that takes into account the security of smart contracts and aims to create new programs, namely decentralized applications that offer a variety of products and services.

As for Scilla, it has four main advantages. These are:

Science-backedScilla is a peer-reviewed smart contract language that supports the world’s most advanced sharded protocol.
Fewer security risksScilla’s static analysis framework and automatic scanners allow developers to more easily identify common security vulnerabilities.
Safer contractsIts strong type system makes it easier to write bug-free code.
Proof of mathematical safetyScilla is inspired by functional programming languages such as OCaml, making it easy to perform formal verification, the automatic mathematical proof of security properties.

Furthermore, Scilla directly leverages sharding architecture to provide a highly scalable and efficient computing network. Zilliqa is the first layer 1 blockchain to implement sharding. Sharding can process up to thousands of transactions per second. For example, with a total of 3,600 nodes, the Zilliqa network can collectively process 2,828 transactions per second. By implementing sharding technology, Zilliqa is able to solve the scalability problems of Layer 1 networks.

Zilliqa’s Ecosystem

The Zilliqa ecosystem is constantly evolving. Currently, Zilliqa has become a platform for thousands of dApps and more than 3700 tokens available in the Zilliqa ecosystem. In addition, the Zilliqa platform also enables staking and yield farming using ZIL tokens. These native Zilliqa tokens are also used in various fields such as advertising, entertainment, financial services, gaming, and payments.

ZIL Token

In 2017, Zilliqa introduced its ERC-20 token, ZIL. This token serves multiple purposes, including storage, transfer, and staking. As the native token of the Zilliqa blockchain, ZIL is specifically created to facilitate the scalability of decentralized applications, spanning various sectors such as financial services and NFT marketplaces.

By holding ZIL tokens, individuals gain access to interact with a wide range of DApps and platform services built on the Zilliqa blockchain. Furthermore, ZIL token holders possess the privilege to participate in network upgrade decisions through staking their ZIL tokens for voting rights.

ZIL tokens total supply is 21 billion tokens. At the time of writing, the supply of ZIL tokens in the market has reached 15,867,699,447.

Use Cases for ZIL

ZIL plays many roles in the Zilliqa ecosystem, acting as the main medium for transactions on the network. In addition, ZIL tokens also serve as a reward to miners for creating new blocks.

Here’s a complete list of how you can use ZIL coin:

Governance TokenThrough the use of Governance ZIL (gZIL) tokens, users enable long-term ZIL holders and network participants to become decision-makers or vote within the network. The supply of gZIL is fixed at a maximum of 722,000 coins.
Staking & Earning RewardsAnyone who buys and stores ZIL can stake ZIL and receive rewards. The minimum stake is 10 ZIL to ensure that no additional gas fees are required to withdraw the rewards earned.
Buying and selling NFTsZIL allows users to mint, sell and own NFT assets on Zilliqa’s six marketplaces. Users must purchase and hold ZIL tokens in wallets such as Zilpay.
Building decentralized applications (DAppsToken holders can create dApps powered by smart contracts that charge transaction fees. In this case, ZIL can act as a gas fee and facilitate transactions, similar to Ethereum.
Creating tokens and raising fundsTo create a token, you can visit the Savant IDE and enter the token details to launch the token while holding ZIL tokens in your wallet. Additionally, you can raise funds for the token by listing it on the ZILSwap Initial Liquidity Offering (ZILO). There, ZWAP holders (another token on Zilliqa) can provide liquidity to the selected token prior to its launch.

The Future of Zilliqa

Zilliqa is the first public blockchain to exclusively use a sharded network, allowing it to achieve high bandwidth and transaction throughput, overcoming the scalability issues faced by many blockchains.

Zilliqa is targeting key sectors such as advertising, entertainment, financial services, gaming, and payments. With its advanced capabilities, Zilliqa aims to become the blockchain of choice for large-scale enterprise applications across multiple industries. The technology offers solutions such as data transparency and transaction speed.

On July 5, 2023, Zilliqa implemented a significant upgrade to its main network, reaching version 9.2. This update aimed to optimize network performance and strengthen cross-chain functionality. One of the key improvements was the interoperability between the Ethereum Virtual Machine (EVM) and Scilla. This enhancement makes it easier to create, test and launch tokens that can be exchanged using ERC-20 and ZRC-2 smart contracts.
