Zilliqa ZIL
First Sharding Chain
🎭 a tireless worker-ant that clones into parallel teams: the bigger its colony grows, the more it can carry
💬 “Most chains slow down as the crowd grows. I do the opposite. Hand me more workers and I split into more teams, each hauling its own pile in parallel. I was the first to prove a blockchain can scale by dividing, not by waiting in line.”
- The idea: split the network into parallel groups called shards, so more nodes means more speed, not more traffic jams.
- The origin: a 2016 research paper at the National University of Singapore; the company formed in June 2017.
- The milestone: mainnet launched 31 January 2019, the first chain to run sharding in production.
- The reboot: Zilliqa 2.0 moved to proof of stake and EVM compatibility, cutting energy use about 99%.
📖 The Story
2016, a university lab in Singapore. Prateek Saxena, a professor at NUS, kept circling one stubborn problem: the older a blockchain gets and the more users it attracts, the slower it tends to run. Bitcoin and early Ethereum both queued every transaction through the whole network, so growth made congestion worse, not better. Saxena's research paper proposed a different shape entirely, borrowed from how big databases cope with load: split the work.
June 2017. The paper became a company, Zilliqa Research, staffed by former NUS research fellows: Dong Xinshu as CEO, Yaoqi Jia as CTO, and Amrit Kumar as chief scientific officer. Their pitch was a single bold word, sharding. Instead of one long line for one cashier, the network would break into many small teams, each handling its own batch of transactions at the same time. Add more computers and you add more teams, so capacity climbs roughly in step with the crowd.
31 January 2019. The mainnet went live and Zilliqa was widely credited as the first blockchain to run sharding in production. The early design was a clever hybrid: it used a small amount of proof of work only as an ID check, to assign nodes to shards and pick a coordinating committee, while the real agreement on transactions ran on a fast, low-energy method called pBFT inside each shard.
Years later the chain rebuilt itself. Zilliqa 2.0 dropped the mining step, moved fully to staking, and added smart contract support compatible with Ethereum's tooling, all rolled out by a hard fork in early 2026. The ant had learned a new way to carry its load.
📊 Stats
🧩 How it works
The core trick is parallel work. A normal chain is one queue: every node checks every transaction, so a bigger crowd means a longer wait. Zilliqa splits its nodes into smaller groups, the shards, and each shard processes its own batch of transactions at the same time. A coordinating group called the Directory Service committee stitches the results back together. More nodes, more shards, more throughput.
🌗 Light & Shadow
- A genuine first: the earliest chain to put sharding into live production, a design that later chains studied and built on
- Its capacity is meant to grow with the network, the rare case where a bigger crowd helps rather than clogs things up
- Academic roots at NUS, with a research paper and named founders behind it rather than an anonymous launch
- Being first did not make it the leader. Newer Layer 1s arrived with louder ecosystems, and Zilliqa's developer mindshare stayed thin
- The early hybrid design and its own smart-contract language, Scilla, made it less familiar to build on, part of why 2.0 leaned on Ethereum compatibility instead
- The 2026 pivot toward gaming and Web3 is a reset, not a proven win: the chain is still rebuilding an audience years after its technical milestone
🧬 Evolution lineage
Zilliqa is not a fork of another coin and has no shared-founder sibling. It is an independent Layer 1 born in a Singapore university lab. Its real legacy is conceptual: as the first production sharding chain, it influenced later scaling designs rather than being copied line for line.

❓ FAQ
- What is Zilliqa?
- A public Layer 1 blockchain that was the first to run sharding in production. Sharding splits the network into parallel groups called shards, so the more computers join, the more transactions it can handle at once instead of slowing down.
- What does sharding actually mean?
- Picture one cashier serving a long line versus ten cashiers each serving a short one. Sharding splits the network into smaller teams that each work in parallel, so adding more workers adds more capacity. Zilliqa was the first chain to ship this idea live.
- Who created Zilliqa and when?
- It grew from a 2016 sharding research paper by Prateek Saxena, a professor at the National University of Singapore. The company Zilliqa Research was set up in June 2017, and the mainnet went live on 31 January 2019.
- What changed with Zilliqa 2.0?
- Zilliqa 2.0 moved the network to proof of stake, added full EVM compatibility so Ethereum-style apps can run on it, and cut energy use by roughly 99 percent. It was rolled out by a hard fork in early 2026, with the ecosystem leaning toward gaming and Web3.
