ccn interview cryptocurrency blockchain

Past week, I was in a position to job interview Zillaqa CEO, Xinshu Dong. As of the producing of this article, Zilliqa (ZIL) is sitting at #32 on CoinMarketCap with a market place capitalization of just in excess of $270 million. The currency peaked at in excess of $1.6 billion in May of 2017. The coin’s meteoric rise occurred as bitcoin was hovering all over the $8,000 amount and it has traditionally executed exceptionally well even in bear markets.

What is Zilliqa?

Comparison of Zilliqa’s throughput to that of current blockchains like Bitcoin and Ethereum.

Zilliqa is a new significant-throughput blockchain that aims to “process countless numbers of transactions for every second” with “high decentralization and significant stability.” The aim of this significant throughput is that developers “can focus on developing… [their] thoughts without the need of worrying about network congestion, significant transaction service fees or stability which are the key concerns with legacy blockchain platforms.” The web-site contains the graph to the left comparing Zilliqa to current blockchains.

This is not to say other blockchains simply cannot process higher transaction volumes, Dong suggests, but the question is what these other blockchains sacrifice in order to maximize their transaction throughput. Other blockchains achieve this conclude by owning marginally a lot more centralized architecture, or by owning some transactions operating off the blockchain. The Zilliqa crew does not compromise with these general performance enhancements, with Dong stating that the crew “believes in the initial spirit of [the] blockchain,” which indicates they “process matters on the blockchain itself” and “maintain a very significant amount of decentralization.” As an alternative, most of their general performance enhancements arrive either via sharding or via functioning on their consensus algorithm to be a lot more effective. Dong suggests with every single transaction as many as 600-800 nodes are concerned. He goes on to reveal how this differs from Ethereum and Bitcoin.

With Ethereum and Bitcoin, Dong suggests, you’ll have involving 10,000 and 20,000 nodes all processing every single transaction. Although the process is very protected and resilient it is not automatically effective. With Zilliqa, the problem was creating certain not every single node had to process every single transaction, but at the very same time creating certain a significant ample quantity of nodes are concerned to achieve decentralization in an effective way. The way this is accomplished at Zilliqa (and how it has been proposed at Ethereum) is via sharding. At a significant amount, sharding indicates spreading out transactions in excess of a quantity of different nodes so that not every single node is accomplishing every single transaction. There are various sorts of sharding at present out there and what Zilliqa is accomplishing immediately is what is called network or transaction sharding and is different from condition sharding, which is accomplished at Ethereum.

Sharding at Zilliqa vs Sharding at Ethereum

Although Dong explains condition sharding in the job interview, the most effective clarification I uncovered was in a paper by chief scientific advisor at Zilliqa Prateek Saxena, and advisor Loi Luu (who also transpires to be an advisor to Kambria, Republic Protocol, and and various some others who do not look to be concerned with the Zilliqa undertaking any longer (namely Viswesh Narayanan, Chaodong Zheng, Kunal Baweja, and Seth Gilbert) all at the Countrywide University of Singapore. The pursuing excerpt from the paper explains how it works:

“ZILLIQA does what is called network or transaction sharding. Think about a sample network of 1,000 nodes. ZILLIQA will immediately divide the network into 10 shards just about every with 100 nodes. Just about every shard can now process transactions in parallel. If just about every shard is able of processing 100 transactions for every 2nd, then all shards together can process 1000 transactions for every 2nd. The skill to process transactions in parallel because of to the sharded architecture makes certain that the throughput in ZILLIQA will increase (about) linearly with the size of the network.”

The paper goes on to reveal how this is different from what is staying investigated at Ethereum:

“Ethereum is at present looking into on what is called condition sharding, i.e., how to divide the blockchain condition so that storage does not come to be an problem in the very long operate. ZILLIQA is not accomplishing condition sharding in its current fast strategy. Managing clever contracts on a sharded network without the need of condition sharding is previously a major problem. Getting said that, condition sharding is in our potential designs.”

The paper goes on to reveal various concerns that exist in the proposed variation of Ethereum condition sharding that will not result Zilliqa’s transactional sharding implementation. Most about is that Ethereum’s proposed implementations do not allow for for cross-shard communication in section 1. This indicates a clever agreement residing in a single shard (out of 100 full) simply cannot call a agreement on another shard. This is not the circumstance at Zilliqa, with “every node owning a view of the international condition,” which would make sharding a great deal a lot more realistic to be reached in the up coming number of months, according to Dong. This is in sharp distinction to Ethereum’s prediction that they will have sharding reside by 2020. That staying said, the Zilliqa crew is certainly wanting at condition sharding very long term as section of their implementation.



Outdoors of some of the issues that the Zilliqa crew has operate into applying a Evidence-of-Function sharding implementation that makes it possible for nodes to holistically view the network whilst making use of an effective consensus mechanism, the crew has operate into a great deal a lot more standard concerns. Bandwith, for instance, has been an problem the Zilliqa crew has had to address for. The way they’ve accomplished this is by owning nodes share transform deltas as opposed to the entire transactional journals (for the whole network as opposed to an specific nodes shard). These deltas are of matters like “account balances” or “the values of variables in a clever agreement,” which are intended to be international.

Aside from scaling the network and know-how, Zilliqa has also had to scale their crew.  This problem was even more exacerbated by the team’s area in Singapore wherever tech expertise is notoriously hard to arrive by, with as many as 70% of Singapore fintech companies struggling to find expertise. Nevertheless, they had some rewards that they had been in a position to leverage.

Very first of all the crew had prepared the codebase a few moments ahead of: the first in the University of Singapore research lab, then once again as Dong and his crew built out private blockchains for consumer function, and eventually on the general public blockchain.

A different point Dong emphasized as staying a key part to his accomplishment was his historical past with the crew. Dong suggests he’s been functioning with a quantity of the crew associates for a long time. For instance, the team’s CSO, Prateek, had been functioning with Dong for 7 a long time.


Zilliqa is a modest crew with the bold goal of building a PoW transactional sharding blockchain able of processing countless numbers of transactions for every 2nd without the need of the use of side chains or centralization. The team’s solid track record in educational study has supplied it a leg up in recruiting more and more tricky to find blockchain expertise, primarily in Southeast Asia. The crew is slated to launch its mainnet late this year or early up coming year, and with its current market place capitalization it will be viewed closely in the cryptocurrency planet.
