Jan Camenisch, a seasoned cryptographer, saw a future beyond the limitations of traditional blockchain technology. Drawn into the burgeoning crypto space, he found a kindred spirit in DFINITY, an entity daring to reimagine the internet as a global computer.
Unlike the replicative nature of blockchains like Bitcoin, DFINITY’s Internet Computer Protocol aims to replicate compute processes, a quantum leap in complexity and potential. With its emphasis on security, efficiency, and decentralized governance through DAOs, ICP is poised to revolutionize industries and reshape our digital world.
Jan Camenisch’s Pioneering Path in Cryptography and Blockchain
Jan Camenisch embarked on his journey over six years ago at IBM Research in Switzerland, where he focused on cryptography, cryptographic protocols for privacy, and distributed systems. His expertise extended to various protocols, enriching his understanding of the field.
Moreover, Jan’s interest was piqued by the emergence of the new crypto space. Delving deeper out of sheer curiosity, he explored different projects within the burgeoning industry. During this time, representatives from DFINITY approached him, seeking his expertise.
Notably, amidst his exploration of various projects, DFINITY stood out with its ambitious mission. Unlike mere Ethereum derivatives, DFINITY aimed to revolutionize blockchain technology by integrating compute capabilities, thus envisioning a “world computer.” Furthermore, Jan found resonance in DFINITY’s vision, seeing an opportunity to apply his extensive background from IBM Research to push the boundaries of blockchain technology. This alignment of vision and capability convinced him to join the DFINITY team.
Understanding ICP’s Unique Approach
The CTO described the ICP blockchain as a revolutionary approach designed from the ground up to secure and reinvent compute processes. Traditional IT systems often lack robust security due to their iterative and patched-up nature, stemming from old mainframe architectures.
Subsequently, Jan Camenisch emphasized the critical need for DFINITY’s ethos in building secure computers. He pointed out that simply replicating systems is insufficient against Byzantine attacks, necessitating the integration of cryptographic protocols. These protocols ensure that even if some parties maliciously deviate from their computations, a consensus can still be reached on inputs, outputs, and processing states.
Furthermore, he highlighted the contrast with other blockchain protocols like Bitcoin, which initially aimed at replicating ledgers — a simpler problem compared to replicating compute processes. He pointed out the complexity of ensuring synchronized program states and handling discrepancies in computational outputs.
“This is where the challenge lies,” Jan reflected, discussing the intricacies of maintaining consistency and security in replicated compute environments. “It’s not just about replication; it’s about secure replication that withstands potential attacks.” He found the task both daunting and stimulating. “It’s a much bigger problem,” he admitted, “but also a much more engaging one to tackle.”
Comparing Protocols with Jan Camenisch: Bitcoin, Solana, and the Internet Computer
Camenisch highlighted the distinct differences between Bitcoin, Solana, and the Internet Computer when it comes to their underlying protocols and operational frameworks.
Bitcoin operates primarily as a protocol relying heavily on hashing for security. This hashing not only facilitates consensus but also integrates mechanisms for participant compensation directly into its protocol design. However, for a high-performance blockchain computer, Jan emphasized the necessity of a modular approach. Such an approach entails separating the consensus protocol from state synchronization and transaction scheduling protocols for smart contracts. Each of these components requires distinct protocols tailored to specific tasks alongside overarching governance structures.
Moreover, he contrasted Bitcoin’s open participation model with the ICP’s approach, termed deterministic decentralization. Here, governance is defined by a smart contract that specifies which nodes constitute a subnet. This method allows for targeted selection of nodes based on criteria like Know Your Customer (KYC) compliance and secure data center operations. By hosting nodes in highly secure environments with known owners, the ICP achieves efficiency and cost-effectiveness. Jan noted that this flexibility enables configurations with as few as 56 nodes per subnet, tailored to varying security needs.
“In essence,” he summarized, “ICP represents a fundamentally different approach to securing computational infrastructure on the internet. By leveraging deterministic decentralization and targeted node selection, we optimize efficiency and security in ways that diverge significantly from traditional blockchain models like Bitcoin and others.”
Enhancing Blockchain Connectivity: A Unique Approach
Jan Camenisch discussed the Chain Fusion initiative, a focal point of their current activities, particularly highlighted during the ECC conference in Brussels and soon to be presented at the Bitcoin Conference in Nashville. The initiative aims to educate the community on its operational mechanics.
The core concept revolves around constructing computers from distinct subnets, each functioning as its own replicated unit. These subnets execute cryptographic protocols, notably employing threshold signing. This capability allows subnets to collectively sign cryptographic transactions, enabling them to interact securely with external blockchains such as Bitcoin and Ethereum.
“One key aspect,” Jan elaborated, “is the ability for our subnets to sign transactions and securely read data from other blockchains.” To achieve this decentralized interaction, nodes within the subnets are integrated as light clients of the external blockchain networks. For instance, nodes within the Internet Computer subnets act as Bitcoin light clients, syncing Bitcoin blocks and deriving the latest Unspent Transaction Outputs (UTXOs) through consensus.
Additionally, the CTO noted the significance for having smart contracts on ICP, stating, “Smart contracts can now reliably access the latest UTXO information, facilitating seamless interactions with Bitcoin.” With their own Bitcoin public keys, these contracts can receive and manage Bitcoin transactions autonomously. They can initiate spending transactions by signing them and instructing the Internet Computer to submit them directly to the Bitcoin network. “This integration,” Jan concluded, “represents a secure bridge between different blockchains, enabling the efficient and trustless exchange of value across decentralized networks.”
Harnessing Subnets for Protocol Uniformity on the Internet Computer
Jan clarified that the Internet Computer Protocol serves as the foundational framework running on every node across all subnets. This protocol standardizes communication and interaction among nodes and subnets within the network.
“The ICP protocol governs how nodes exchange messages and reach consensus on transactions,” Jan explained. “It also facilitates communication between subnets, allowing smart contracts on different subnets to interact seamlessly.”
He likened this structure to a replicated version of the internet itself, where subnets function akin to replicated computers. Each subnet operates under the same protocol, ensuring uniformity and compatibility in communication protocols and consensus mechanisms.
“In essence,” Jan summarized, “the Internet Computer operates as a unified network where subnets, akin to individual computers, collaborate and communicate based on shared protocol standards.”
Seamless Integration of Subnets and Smart Contracts
The DFINITY CTO explained that within the Internet Computer network, subnets indeed support HTTPS requests, allowing for the hosting of complete websites directly through ICP. Essentially, subnets function similarly to regular computers with HTTPS capabilities. They can both receive and send HTTP requests, enabling robust interaction within the network.
Regarding smart contracts on the Internet Computer, he pointed out their unique capability to serve front ends directly in users’ browsers. Each smart contract possesses its own identifiable URL based on its smart contract ID. Additionally, custom URLs can be configured through routing mechanisms, facilitating specific application needs.
“For instance,” he illustrated, “applications like OpenChat operate entirely as smart contracts on the Internet Computer. This means it functions as a comprehensive end-to-end application composed exclusively of smart contracts, devoid of external cloud services.”
In summary, Jan Camenisch highlighted the Internet Computer’s capability to seamlessly deploy and manage decentralized applications (dApps) and services. By leveraging smart contracts for frontend operations and supporting HTTP-based interactions, ICP facilitates secure, reliable, and fully decentralized application development and deployment.
Unlocking Innovative NFT Capabilities on ICP
Moving along in the interview, we asked the CTO whether images were hosted on ICP compared to other projects where NFTs are typically represented by metadata pointing to an NFT.
Jan explained that on the Internet Computer, smart contracts have the capacity to store up to 400 gigabytes of data, which contrasts sharply with platforms like Ethereum where such storage would be economically impractical.
“ICP allows for storing substantial amounts of data directly within smart contracts, including NFTs. This capability opens up numerous exciting opportunities where NFTs can be more than just static metadata,” Jan confirmed. Notably, he elaborated with an example: “Consider the ‘Bitcoin Flower’ created by street artists in Paris. This NFT changes its colors based on real-time fluctuations in the Bitcoin price. It demonstrates how NFTs on ICP can be programmable, essentially functioning as interactive programs.”
Furthermore, he emphasized the versatility of NFTs on ICP, noting that any digital artifact can be tokenized as an NFT. This includes items such as in-game assets, like swords, where an NFT representing a game item could be utilized across multiple games interacting with the same smart contract.
“In essence,” he concluded, “by storing NFTs on-chain on ICP, we unlock a range of innovative possibilities. NFTs become dynamic, programmable assets capable of interacting with decentralized applications and adapting to real-world data.” Jan painted the picture of how the Internet Computer is redefining the potential of NFTs, providing a robust platform for creating and deploying flexible digital assets that transcend traditional static tokens.
Reduced Energy Consumption and Enhanced Efficiency of the Internet Computer
We asked Jan about the energy footprint of ICP compared to proof of work mining and other consensus algorithms, noting POW’s significant energy intensity. Essentially, we inquired whether ICP’s energy consumption is substantially lower and how it contrasts with proof of work mining in terms of environmental impact and efficiency.
The CTO explained that the Internet Computer significantly reduces energy consumption compared to traditional Proof of Work (PoW) mining and other consensus algorithms.
“The energy consumption on the Internet Computer is transparently displayed on our dashboard,” Jan began. “Some subnets on ICP operate with as few as 13 nodes, each consisting of high-grade server machines that are inherently power-efficient. This makes the Internet Computer one of the greenest blockchains available.”
Moreover, he elaborated on the efficiency of ICP compared to traditional IT stacks: “In traditional cloud environments, there’s already inherent replication for backups, content distribution systems, and firewalls. However, these are often patchwork solutions. In contrast, blockchain protocols like the Internet Computer embrace replication as a core design principle. For instance, a 30-node network on ICP automatically distributes content across different global locations, eliminating the need for separate content distribution systems. Moreover, the blockchain’s inherent security design means there’s no need for additional firewalls.”
Additionally, he emphasized the security benefits of blockchain: “Just like Bitcoin, which has never been hacked itself, the Internet Computer’s secure-by-design approach ensures robust protection. This approach to building a secure computing system ultimately translates into significantly improved energy efficiency compared to traditional IT architectures.”
Exploring ICP Ecosystem Projects and DAOs
We inquired about ICP ecosystem projects with Jan, particularly those that had caught his interest.
“There are numerous projects,” Jan noted. “For instance, OpenChat functions much like a WhatsApp or Reddit clone entirely powered by the Internet Computer. What’s intriguing is that OpenChat operates as a DAO. It issues its own tokens, and token holders can participate in governing the application.”
Furthermore, he described the governance process: “Developers proposing updates to OpenChat must submit their proposals to the DAO. Token holders, who stake their CHAT tokens, then vote on whether to approve or reject these proposals. Only upon adoption by the token holders will the smart contracts update themselves. This setup enables a fully autonomous application where all functionalities are executed on-chain.”
Jan Camenisch drew a parallel to a nervous system governing the application, akin to the organizational structure found in biological systems. He mentioned the growing trend of DAO-based decentralized applications on ICP, noting the presence of around 20+ such autonomous organizations actively contributing to the network.
In essence, he underscored the significant role of DAOs within decentralized applications on the Internet Computer, emphasizing their capacity to foster community-driven governance and autonomous operational frameworks for digital services.

Anticipating the Future
Camenisch looks forward to broader blockchain adoption, particularly in enhancing security and computing practices. He finds the convergence of blockchain with AI especially compelling due to AI’s unique operational nature, which demands stringent security measures. Furthermore, Jan pointed out that blockchain’s decentralized nature can mitigate single points of failure, ensuring tamper-proof and verifiable AI outputs.
Additionally, he showcased DFINITY’s efforts in demonstrating AI capabilities on-chain, such as image and face recognition, and aims to integrate GPU-powered subnets for secure AI operations. Ultimately, Jan Camenisch is driven by the opportunity to address critical global challenges like cybersecurity and secure AI deployment through innovative blockchain solutions.
