The world of blockchain technology is evolving rapidly, with new Layer 1 (L1) networks launching regularly in an effort to solve scalability, security, and decentralization challenges. Amid this competitive landscape, Zilliqa (ZIL), one of the earliest sharded blockchains supporting smart contracts, has demonstrated resilience and technical maturity—particularly after a recent network recovery that highlighted both its vulnerabilities and strengths.
In a surprising twist, Amrit Kumar, co-founder of Zilliqa, stepped back from his leadership role in May 2025 but remains a respected voice in the blockchain space. On the occasion of Zilliqa’s fifth anniversary, he offered insightful commentary on what truly sets successful blockchains apart—focusing particularly on Ethereum (ETH) as a model of sustained innovation.
Rapid Recovery: Zilliqa Restarts Mainnet Within 24 Hours
On July 30, 2022, Zilliqa faced a critical network disruption that temporarily halted block production. The issue stemmed from a technical flaw involving the ecdsa_recover_pk function call in Scilla—the blockchain’s native smart contract language. This function failed due to improper handling by the underlying OCaml-based secp256k1 cryptographic library.
As a result, new blocks could not be validated or added to the chain, effectively freezing network operations.

However, the Zilliqa development team acted swiftly. Within less than 24 hours, they deployed a recovery update (v8.1.2), restoring full functionality to the mainnet by 20:00 UTC on July 30. In an official statement posted on their blog and social channels, the team acknowledged the incident and apologized for any inconvenience caused to users and stakers.
Node operators were instructed to upgrade their software immediately to ensure seamless participation in consensus. While most services resumed quickly, some stakers experienced minor delays in reward distribution—a common side effect during emergency upgrades.
This rapid response underscored Zilliqa’s operational agility and commitment to network stability, especially considering the incident occurred just one day before the project’s fifth anniversary.
The Innovation Imperative: Why Ethereum Leads the L1 Race
While reflecting on Zilliqa’s journey, Amrit Kumar shifted focus to broader industry trends—particularly the divergent paths taken by various Layer 1 blockchains. He emphasized that long-term innovation, not short-term gains, is the key differentiator between enduring platforms and those that fade into obscurity.
Ethereum (ETH), according to Kumar, exemplifies this principle.
“Constant innovation has kept Ethereum alive for all these years despite all the issues. Most if not all other L1s stopped innovating soon after they launched and instead started mimicking short-term success strategies.”
Kumar pointed out that while many competing blockchains chase quick wins through aggressive marketing, token speculation, or superficial feature copying, Ethereum continues to invest in foundational upgrades—such as the transition to proof-of-stake, rollup-centric scaling roadmaps, and ongoing improvements in security and efficiency.
This culture of continuous improvement allows Ethereum to adapt to changing demands without sacrificing decentralization or trustlessness.
Bitcoin’s Role in the Ecosystem
Interestingly, Kumar also weighed in on Bitcoin (BTC), noting that it should not emulate the strategies of newer L1s. Instead, Bitcoin’s strength lies in its simplicity, scarcity, and unchanging monetary policy.
“Bitcoin cannot and should not be like those other L1s.”
He argued that Bitcoin serves a unique role as digital gold—a secure, censorship-resistant store of value—while Ethereum functions more like digital oil: a programmable foundation powering decentralized applications across finance, identity, gaming, and more.
This distinction reinforces the idea that there isn't a "one-size-fits-all" blockchain solution. Rather, diverse networks fulfill complementary roles in the broader Web3 ecosystem.
Core Blockchain Keywords Driving Industry Discourse
To better understand the context of Kumar’s insights, it's essential to identify the core keywords shaping current discussions around blockchain evolution:
- Ethereum (ETH)
- Layer 1 (L1) blockchain
- Zilliqa (ZIL)
- Smart contracts
- Scalability
- Decentralized applications (dApps)
- Blockchain innovation
- Network resilience
These terms reflect user search intent and represent central themes in developer debates, investor analysis, and ecosystem growth metrics.
They naturally appear throughout technical documentation, community forums, and market commentary—highlighting the importance of integrating them organically into content without forced repetition.
Frequently Asked Questions (FAQ)
What caused Zilliqa’s network outage in 2022?
The outage was triggered by a bug in the ecdsa_recover_pk function within Scilla, Zilliqa’s smart contract language. The issue originated from incorrect handling by the OCaml implementation of the secp256k1 cryptographic library, which prevented proper block validation.
How fast did Zilliqa recover from the incident?
Zilliqa restored full mainnet operations within 24 hours. The recovery update (v8.1.2) was completed on July 30, 2022, at 20:00 UTC.
Why does Amrit Kumar believe Ethereum is superior to other L1s?
Kumar credits Ethereum’s sustained success to its culture of constant innovation. Unlike many competitors that stop evolving post-launch or copy others’ tactics for short-term gains, Ethereum consistently delivers major protocol upgrades that enhance scalability, security, and sustainability.

Did Zilliqa’s anniversary coincide with the recovery?
Yes—the network recovery was completed on July 30, 2022, just one day before Zilliqa marked its fifth anniversary since mainnet launch on July 31, 2017.
Is Zilliqa still active in the blockchain space?
Yes. Despite leadership changes—including Amrit Kumar stepping down in May 2025—Zilliqa continues to operate and contribute to research on sharding and secure smart contract execution.
What lesson can other blockchains learn from Ethereum?
The primary takeaway is the importance of long-term vision over short-term hype. Sustainable growth comes from continuous technical advancement, community-driven governance, and adaptability—not just high yields or viral trends.
Final Thoughts: Building for the Long Haul
Amrit Kumar’s reflections serve as a timely reminder that in blockchain, as in any transformative technology, longevity depends on more than just speed or transaction cost. It hinges on vision, resilience, and an unwavering commitment to solving hard problems.
Zilliqa’s ability to recover quickly from technical setbacks shows maturity. Meanwhile, Ethereum’s decade-long journey illustrates how consistent innovation can create an ecosystem so robust that it becomes the benchmark against which all others are measured.
For developers, investors, and enthusiasts alike, the message is clear: focus on sustainable progress, embrace challenges as opportunities to improve, and build systems designed not just for today—but for the next decade.
