Cryptographic agility could become critical for Web3.

If a blockchain’s security assumptions change, how quickly can it transition to a new signature scheme without disrupting users and existing assets?

What does a quantum ready blockchain actually require?

Quantum resistance is as much a systems design problem as a cryptography problem.

#IBW2026 #Blockchain #QuantumComputing #Web3

[Subhash Wary @SubhashWary]

Blockchain relies on cryptographic assumptions

As quantum computing advances the focus will increasingly shift from “Can quantum break this?” to “Can decentralized systems upgrade their cryptography before it matters?”

Post Quantum Cryptography could become an important part of Web3 infrastructure.

The interesting question is how decentralized networks can migrate to quantum resistant signatures without disrupting existing users, assets and consensus mechanisms.

#IBW2026 #Web3 #Blockchain

[Subhash Wary @SubhashWary]

Quantum computing could eventually change the security assumptions behind blockchain.

The challenge isn’t only encryption:
Digital signatures, wallet security, key management and protocol migration all need to be considered.

@softkiln_ Exactly, right, a scaling puzzle with trade offs

[Subhash Wary @SubhashWary]

Areas: Layer-2 scaling, zero-knowledge proofs, decentralized physical infrastructure (DePIN), account abstraction, interoperability and blockchain security are solving very different parts of the same problem: making decentralized systems practical at scale.

Blockchain interoperability:

How can independent networks communicate securely without introducing new trust assumptions or creating additional attack surfaces?

#IBW2026 #Blockchain #Web3 #DistributedSystems #Cybersecurity

[Subhash Wary @SubhashWary]

Zero-knowledge proofs are one of the areas I’m particularly interested in exploring.
The idea of proving that something is true without revealing the underlying information raises questions around privacy, verifiability, computational cost, scalability.

I’ll be paying closer attention to the engineering behind Web3, from consensus mechanisms and cryptographic proofs to rollups, data availability and decentralized storage. It's shaping how decentralized systems can become more scalable and secure.

#IBW2026 #DistributedSystems

[Subhash Wary @SubhashWary]

Web3 is increasingly becoming an infrastructure problem. How do we make decentralized networks faster, cheaper, more secure, interoperable and easier to use without losing the properties that make them decentralized?

A new technology is always interesting when you stop asking “What is it?” and start asking “What can we build with it?”

I’m curious about the ideas that are moving beyond conversations and into actual products, protocols and infrastructure.

#IBW2026 #IndiaBlockchainWeek #Web3

[Subhash Wary @SubhashWary]

From writing code to working with hardware, I’ve always enjoyed understanding what happens underneath the surface. Blockchain is another layer of technology to explore different architecture, different constraints, different ways of thinking.

#IBW2026 #Web3 #Blockchain

[Subhash Wary @SubhashWary]

Not every technology needs to be understood from the outside.

Sometimes you need to be in the room where people are building it.

Curious to see what’s real, what’s early and what’s next.

#IBW2026 #IndiaBlockchainWeek #Web3

[Subhash Wary @SubhashWary]

One thing I’ve learned from working with technology: the most interesting ideas usually sit at the intersection of different fields. What developers and builders are experimenting with, which ideas are gaining real traction.

#IBW2026 #IndiaBlockchainWeek #Web3

[Subhash Wary @SubhashWary]

Can we build systems where trust is distributed?
What if computation itself works differently?

Put those questions together and you get some interesting problems around cryptography, security and decentralized infrastructure.
#IBW2026 #QuantumTechnology #Web3 #Cryptography

[Subhash Wary @SubhashWary]

Two technologies are pushing us to rethink the foundations of computing and the internet:

Web3 → decentralized trust
Quantum → new models of computation

The real engineering challenge may be what happens when these ideas start interacting.

#IBW2026 #QuantumComputing #Web3

[Subhash Wary @SubhashWary]

Web3 is changing how we think about ownership, trust and decentralisation.

Quantum technology could change how we think about computation and security.

Interesting part is where these two meet around cryptography and decentralized.

#IBW2026 #QuantumTechnology #Web3 #Blockchain

[Subhash Wary @SubhashWary]

Every technology goes through a phase where it moves from being something people talk about to something people actually build with.

At IBW 2026, I want to get closer to the problems developers are trying to solve right now.

Coming to Mumbai to understand in...

[Subhash Wary @SubhashWary]

At IBW 2026, I’m looking forward to exploring how blockchain systems are being engineered for scalability, security, decentralization and real world adoption from ZK systems and smart contracts to DePIN and decentralized infrastructure.
