Zilliqa is a blockchain platform that is designed to scale securely in an open, permission-less distributed network.
The idea of the Zilliqa blockchain was conceived in the Computer Science Lab at the University of Singapore, based on a paper written by Lui Loo, the cofounder of Kyber Network.
To date, thousands of dApps (Decentralized apps) are being built on top of the Ethereum Blockchain, aiming to attract millions of users. The current Ethereum Blockchain max transaction rate is approximately 15 transactions per second, which is obviously not enough to handle the expected transaction volume, even if only a few Dapps succeed. This situation is making Dapp developers seek off/on-chain solutions.
Recently, Zilliqa launched its private testnet. Their current transaction volume is 2,488 transactions/sec with 3,600 nodes in the network. With Zilliqa, as the number of nodes in the network rises, so does the number of transactions per second. With a network size of 10,000 nodes, Zilliqa will enable a throughput that matches that of VISA and MasterCard with much lower fees for the merchants (the expected throughput is approximately 8,000 transactions/sec).
The project is aiming to serve as an alternative, scalable and secure solution for Dapps to be built on.
The team is aiming to launch its main-net in Q2, 2018.

Zilliqa Blockchain- Technical Aspects
Zilliqa project prides itself on being “The world’s first high-throughput public blockchain platform”. High-Throughput Computing or HTC is a way of utilizing computing power by breaking its load into many small loosely-coupled tasks and distributing the workload across a grid of many different computers.
Zilliqa utilizes HTC and uses network sharding – “dividing the mining network into smaller consensus groups called shards, each capable of processing transactions in parallel”, supposedly Zilliqa’s blockchain will process more transactions per second as more mining nodes join the network. This may sound intuitive, but in reality, the greater the number of nodes the greater the processing time.
In order to understand the framework of Zilliqa, one must first understand the general idea of consensus. A consensus in Blockchain is the mechanism in charge of approving new information being appended to the blockchain across all the decentralized nodes, the most common consensus protocol is Proof of Work (POW), which is usually referred to as mining.
In a high level, the Zilliqa framework is built of two main components:
An independent group of nodes that are responsible for validating a portion of the transactions. In order to do so, each shard will need to decide on its own consensus. This will be done by another consensus approach named Byzantine Fault Tolerance Algorithm or PBFT protocol. At a high level, for each shard, a leader is selected. This leader will validate a constant amount of transactions and create a new block. Then the block will be validated by the other nodes of the shard. If the vast majority of the nodes in a shard accept the block, it will be addressed to the DS Committee in order for the block to be accepted in the general consensus of the Zilliqa blockchain.
This is a group of nodes that manage the activity of Zilliqa’s framework. We can divide their role into two main parts: Building the general consensus (the Zilliqa general blockchain) and maintenance of the Zilliqa framework.
Building the general consensus
As we mentioned before, each shard is only aware of the transactions that were assigned to it. After some shard has finished creating a new block it is sent to the DS Committee. The DS Committee needs to decide whether to add this block to the general blockchain. This is done by executing another process of the PBFT consensus protocol.
The DS Committee is also responsible for some general utilities of the framework. For example, when a new transaction is being broadcasted to the Zilliqa network, the DS Committee decides which shard will receive this transaction. Another role of the DS Committee is to assign a new node in the network to its suitable shard.
Zilliqa also utilizes the Proof Of Work consensus approach in its framework. POW is used solely for the purpose of establishing mining identities both for the DS Committee and for the shards.
ZIL token use – the fuel of the blockchain
ZILs are the driving force behind the Zilliqa Blockchain, as ETH is for the Ethereum Blockchain.
ZILs are consumed by paying fees to the network nodes. One must hold ZILs in his wallet in order to transfer ZILs or other future tokens to be created on top of the Zilliqa blockchain (Made equivalent to ERC-20 tokens on the Ethereum blockchain, serving hundreds of ICOs each month).
Before Zilliqa main-net goes live, Interim ERC-20 tokens will be generated and allocated to various parties, including contributors to the ICO.
These interim ERC-20 tokens will be issued to the initial holders and be transferable within 2 weeks after the completion of the ICO. They are expected to be migrated to the Zilliqa main-net as ZIL tokens in 2018.
The team initially intended to raise a total hard cap of 20M USD (Private sale- ~12M USD, public sale – ~8M USD). Unfortunately (or not), the ETH/USD price had spiked since the end of ZIllilqa’s private allocation, and the 44,000 ETH raised turned out to be more than 20M USD. The team announced that their public allocation was canceled as they had raised the money needed for future development.
Hearing the voice of their community, the team recently announced that it will raise its hard cap a bit (+4445 ETH) and reopened its public allocation period.
Zilliqa Review and Rating
Stage of The Project9.0/10
Token Sale Terms9.0/10
- Team and advisory board: The team consists of highly respected PhDs from top universities in the world. The project is on behalf of Prateek Saxena‘s lab at the University of Singapore, which had published award winning papers in the field of cryptocurrencies and blockchain solutions.
- Project potential: With the rising acceptance of blockchain technology, start-ups are not the only ones building their applications on top of the block-chain. Big companies with millions of active users (i.e. Kik, AIG, Unikrn, EnjinCoin and more) are also doing so. There is obviously a demand for a high throughput blockchain infrastructure and Zilliqa is on the right track to achieve that goal.
- Project Status: Testnet is live with 3,600 Nodes enabling 2,488 transactions/sec (approximately 10-15 times the max transactions/sec on ETH/BTC blockchains). The main-net is to be live on Q2 2018 and Dapps development will start on Q3 2018.
- Token Mechanism: The hard cap is ~48,445 ETH (Equivalent to ~32M USD at the time of writing), if you follow all top 20 tokens by market cap @ coinmarketcap.com, most of them are projects based on their own blockchain (Not ERC-20 projects) valued from ~1.2B USD (Waves) to ~300B USD (Bitcoin). Their hard cap definitely leaves room for growth in the ZIL market cap price in the near future.
- Competition: Zilliqa is competing with top smart contracts blockchains like Ethereum, EOS, and other upcoming projects. The Ethereum blockchain has been live and tested for around 3 years, the community behind Ethereum is huge and there is great development to come, with the aim of addressing issues like scalability, power consumption and more. Though, the ecosystem is expected to grow so there is likely room for blockchains to live alongside each other.
