From Zero to Mainnet: How InfStones Helped Zama Launch the World's First FHE-Powered Confidential Blockchain

When Zama set out to launch the world's first Fully Homomorphic Encryption (FHE) protocol for public blockchains, the team faced a challenge every new Layer 1 knows well: cutting-edge technology only matters if the infrastructure running it is bulletproof from day one. InfStones was selected as a Genesis Operator — and this is the story of how enterprise-grade infrastructure turns a network's most ambitious vision into production reality.

The Challenge: Launching a Novel Network from the Ground Up

Zama is building something that has never existed at scale before: a cross-chain confidentiality layer that allows public blockchains to run encrypted computations natively, using Fully Homomorphic Encryption. Unlike traditional privacy solutions that rely on zero-knowledge proofs or trusted execution environments, Zama's FHE coprocessors perform computations directly on encrypted ciphertext — meaning validators and operators never see the underlying data.

This is a profound architectural departure from standard blockchain infrastructure. Running Zama is not simply spinning up validators and monitoring uptime. It requires:

• FHE coprocessor operations — specialized compute nodes that perform encrypted computation off-chain, with demanding CPU/GPU requirements and strict latency constraints
• MPC/KMS node management — threshold key management infrastructure that distributes decryption authority across multiple parties, so no single operator can access user data
• Hardened key security — cryptographic material handling at a level commensurate with institutional finance, not typical blockchain operations
• Seamless scaling — the ability to grow from a closed testnet to open mainnet without operational disruption

For Zama's launch to succeed, the infrastructure partners selected at genesis could not afford to learn on the job. The stakes — both technical and reputational — demanded operators with a proven track record across multiple networks and operational environments.

Why Zama Selected InfStones as a Genesis Operator

Genesis operators are not chosen casually. They are the foundational layer of a new network's security model — the entities responsible for ensuring that the network's earliest blocks are produced reliably, that the cryptographic infrastructure is operated with precision, and that the technical architecture holds under real-world conditions before the broader validator set joins.

InfStones was selected as one of Zama's Genesis Operators on the strength of several factors that matter specifically to a novel, technically complex L1 launch:

a) Track record across 80+ networks. With over 20,000 nodes supported across more than 80 blockchains, InfStones brings operational depth that most infrastructure providers cannot match. When Zama's engineering team evaluated candidates, they needed confidence that their genesis operators had navigated diverse network architectures — from EVM-compatible chains to proof-of-stake validators to specialized computation layers.

b) Enterprise-grade reliability from day one. High-availability infrastructure with automated failover, 24/7 monitoring, and cloud-agnostic deployment is standard operating procedure at InfStones, not a premium add-on. For a network where downtime in the FHE coprocessor layer could affect encrypted state transitions across multiple chains, this baseline reliability was non-negotiable.

c) Hardened key management expertise. The MPC/KMS infrastructure at the heart of Zama's decryption system requires operators who understand how to handle cryptographic keys under institutional-grade security standards. InfStones' experience with staking infrastructure, validator key management, and SOC 2 Type I compliance provided the security posture Zama required.

d) Dedicated infrastructure for FHE's computational demands. FHE is computationally intensive by design. Rather than sharing capacity across commodity pools, InfStones provisions dedicated infrastructure for Zama — ensuring the performance envelope required for encrypted computation is consistently met, even as network activity scales.

What InfStones Delivered: The Infrastructure Layer

As a Genesis Operator, InfStones' contribution to Zama's launch spanned every layer of the network's operational stack:

FHE Coprocessor Operations

InfStones runs and maintains Zama's FHE coprocessors — the off-chain computation nodes that monitor on-chain events, execute encrypted computation, and write updated ciphertexts back to the host chain. These nodes operate with production-grade reliability, continuous monitoring, and automated failover to ensure that the confidential computation layer remains available even under adverse conditions.

MPC/KMS Node Management

The threshold Key Management System distributes Zama's decryption authority across multiple independent operators. InfStones operates KMS nodes within this distributed system, contributing to the security guarantee that no single entity — including InfStones itself — can decrypt user data unilaterally. This is enterprise security architecture applied to a decentralized protocol.

Dedicated Infrastructure for FHE Workloads

Unlike generic cloud deployments, InfStones provisions infrastructure specifically sized and tuned for FHE's computational requirements. As Zama's network evolves — from CPU-based FHE execution toward GPU acceleration and ultimately FHE-specific ASICs — InfStones' cloud-agnostic deployment model allows infrastructure to scale alongside the protocol's performance roadmap without forcing architectural migrations.

From Testnet to Mainnet: Continuity That Matters

One of the most operationally significant aspects of InfStones' Genesis Operator role is the continuity it provides across the network's lifecycle. New L1 networks often face a dangerous gap between testnet and mainnet: the operators who ran testnet infrastructure are not always the same ones operating mainnet, creating knowledge loss at the worst possible moment.

InfStones' participation beginning at genesis means the same operational team that learned Zama's infrastructure during early testing carried that knowledge directly into the production launch. Monitoring configurations, incident response playbooks, key management procedures, and performance baselines were all established before the network opened to the public — eliminating the learning curve that introduces risk in a new network's most vulnerable period.

The Results: What a Genesis Partnership Delivers

The outcome of InfStones' Genesis Operator engagement with Zama demonstrates what enterprise-grade infrastructure partnership means in practice:

• Network launch continuity — Zama's transition from testnet to mainnet proceeded without the operational disruptions that often accompany novel network architectures at first production scale
• Security model integrity — The MPC/KMS infrastructure operated by InfStones contributes directly to Zama's cryptographic security guarantees, ensuring that decryption authority remains distributed and that user data confidentiality is preserved
• Institutional-grade reliability — FHE coprocessors and KMS nodes maintained the uptime and performance standards required to support institutional use cases from day one of mainnet operation
• Scalable foundation — The infrastructure architecture established at genesis provides a production-grade foundation that scales as Zama grows its ecosystem, adds new host chains, and serves increasing transaction volumes

The Pattern: What New L1s Should Know

Zama's launch illustrates a principle that applies broadly to new Layer 1 networks and specialized blockchain protocols: the quality of genesis infrastructure sets the ceiling for a network's institutional credibility.

Developers and institutions evaluating a new network do not just assess the protocol's technical design. They assess the reliability, professionalism, and track record of the infrastructure operators running it. A technically brilliant protocol operated by inexperienced validators will underperform against a simpler network operated by enterprise-grade infrastructure providers.

InfStones brings to every new network partnership the same operational foundation it has built across 80+ blockchains:

• Production-grade validator infrastructure with 99.9%+ uptime SLAs
• Cloud-agnostic deployment that fits within institutional compliance boundaries
• Experienced operator teams who have navigated testnet-to-mainnet transitions for networks spanning every major consensus mechanism and VM architecture
• 24/7 monitoring and automated failover built into every deployment, not bolted on as an afterthought
• SOC 2 Type I compliance as a baseline security posture

For new L1 networks seeking early infrastructure partners, the question is not just "who can run nodes?" It is: "who can make our network credible to the institutions and developers we need to succeed?"

Looking Ahead: InfStones as the Infrastructure Bridge for New Networks

The Zama partnership represents one of several genesis-level engagements where InfStones has played a foundational role in a new network's launch — including Monad, where InfStones supported the network from Testnet 1 through mainnet as both a genesis validator and the infrastructure backbone of Monad's public RPC access.

As blockchain architecture continues to evolve — from high-throughput EVM chains to FHE-powered confidential protocols to AI-integrated computation networks — the infrastructure requirements at genesis will only grow more demanding. The networks that launch successfully will be those that chose production-grade infrastructure partners who could handle the complexity from day one.

InfStones is that partner — trusted by the top blockchain companies in the world, and ready to bring the same enterprise-grade reliability to the next generation of network launches.
