House Party Protocol (HPP) is a cost-efficient, scalable, and developer-friendly Layer 2 (L2) network built on the Arbitrum Orbit. Secured by Ethereum and enhanced through data availability with Eigen DA, HPP delivers modular and performant infrastructure for the next generation of decentralized applications.
At its core, HPP is a unified AI-powered blockchain and data infrastructure, co-developed in collaboration with Aergo, Alpha Quark (AQT), Booost, and VaaSBlock. Designed to bridge the gap between enterprise-grade systems and decentralized networks, HPP focuses on three critical pillars: trustworthy data, verifiable AI, and real-world scalability.
Through its partnership with Conduit as a Rollup-as-a-Service (RaaS) provider, HPP enables developers to quickly and easily deploy rollup nodes, accelerating the growth of an open and accessible Web3 ecosystem.
The era of hype-driven blockchains is behind us. As the industry matures, attention is shifting toward platforms that solve real problems, support real users, and deliver real value.
HPP (House Party Protocol) emerges from this changing landscape as a next-generation platform built on the proven foundation of Aergo — a hybrid blockchain network trusted by governments, enterprises, and institutions across industries.
Aergo has already powered mission-critical applications in logistics, decentralized voting, official document verification in healthcare, and more. By bridging traditional systems' reliability with public networks' openness, Aergo has helped Web2 organizations transition to Web3.
HPP builds on this legacy, expanding the vision with modern infrastructure designed for AI-native, data-centric, and enterprise-ready use cases.
As part of the Arbitrum Orbit initiative, HPP is building a highly interoperable and modular chain architecture that supports shared liquidity, secure bridging, decentralized governance, and routine upgrades. Leveraging Eigen DA for data availability, HPP enhances scalability while maintaining transparency and resilience at the network level.
HPP is fully EVM-compatible, offering seamless integration with widely adopted Ethereum development tools and frameworks. Developers can leverage familiar workflows while benefiting from significantly lower costs and higher performance, enabling the deployment of AI-integrated, data-centric applications at scale.
House Party Protocol is building the future of decentralized infrastructure, where intelligent systems, secure data, and open access converge. By collaborating with key ecosystem partners and empowering developers, HPP brings us one step closer to a world where Web3 becomes as natural and accessible as Web2.

Let’s build something amazing together.
A Gateway to Verifiable Off-Chain Intelligence
Smart contracts are powerful but limited — they can’t think, adapt, or process complex real-world data. As Web3 intersects with AI, RWA, and scientific computation, this becomes a major bottleneck. Noosphere introduces a verifiable off-chain intelligence layer, enabling smart contracts to securely delegate inference and computation
Smart contracts revolutionized the game by introducing decentralized, deterministic, and transparent automation. But as the use cases for Web3 evolve, touching AI, real-world assets, and scientific modeling, those same design principles begin to feel limiting.
Smart contracts were never meant to think. They can’t infer, predict, adapt, or process complexity the way humans (or AI) can. This bottleneck has become one of the biggest blockers to building intelligent dApps.
While this design ensures security and transparency, it severely limits the capabilities of Web3 applications. Smart contracts cannot:
Perform AI inference (e.g., LLM-based responses)
Aggregate multi-source or time-sensitive data
Execute heavy off-chain computations
Dynamically interact with complex, uncertain real-world conditions
This forces developers to either:
Build oversimplified logic directly on-chain, or
Depend on centralized APIs or external scripts, undermining decentralization and verifiability.
Without off-chain computation, smart contracts can’t process large datasets, verify model outputs, or manage economic incentives related to data generation and verification. Worse, the absence of verifiability creates a black box. As a result, decentralized applications across DeFi, DeSci, and RWA are often stuck between being too limited to be useful or too centralized to be trusted.
What we need is not just more data. We need a programmable, auditable, and privacy-preserving delegation layer that brings intelligent logic to on-chain while preserving decentralization.

That’s where Noosphere comes in. It enables smart contracts to securely delegate off-chain computation to verifiable agents, bridging the gap between on-chain determinism and off-chain intelligence. With Noosphere, decentralized applications can reason, adapt, and act intelligently without sacrificing decentralization, privacy, or auditability.
With Noosphere, developers can:
Request off-chain computation directly from smart contracts, including LLM inference, risk assessments, or simulations.
Receive verifiable responses and integrate them securely into on-chain workflows.
Build privacy-preserving, intelligent dApps using a unified framework that combines compute infrastructure, oracles, and verification layers.
Orchestrate AI agents
By serving as a decentralized coordination and verification layer for off-chain logic, Noosphere upgrades the capabilities of smart contracts across all major sectors.
DeFAI Agents (via ArenAI): Agents powered by off-chain AI models that autonomously allocate assets, hedge risks, or rebalance portfolios across chains, integrated directly into DeFi.
DeSci Protocols: Scientific research platforms can outsource high-performance modeling (e.g. protein folding, climate simulation) to Noosphere agents.
On-Chain RWA Intelligence: Tokenized real-world assets (real estate, receivables) gain real-time valuations, credit scores, or logistics tracking via AI models verified through Noosphere.
As decentralized applications evolve beyond static logic and into intelligent, adaptive systems, the need for verifiable off-chain computation becomes urgent. Noosphere fills this gap, not by replacing smart contracts, but by extending their capabilities with off-chain AI reasoning, data coordination, and secure delegation. Whether you’re building in DeFi, DeSci, RWA, or beyond, Noosphere unlocks the infrastructure to make your dApps not just programmable, but truly intelligent.
Inference Markets for Synthetic Datasets: Researchers can generate and verify AI-based interpretations in medical, legal, or financial contexts. Tokens are staked to incentivize validation, with outputs coordinated and verified through Noosphere.
The HPP Airdrop is designed to recognize the community, contributors, and pioneers helping shape the future of AI-native infrastructure. Whether you’re a long-time supporter, an active participant, or a builder ready to launch on HPP, there will be multiple ways to earn.

CPU
4 core CPU (for AWS, a t3 xLarge instance)
Storage Type
NVMe SSD drives are recommended
Storage size
Depends on the chain and its traffic overtime
Please note that:
These minimum requirements for RAM and CPU are recommended for nodes that process a small amount of RPC requests. For nodes that require processing multiple simultaneous requests, both RAM and number of CPU cores will need to be scaled with the amount of traffic being served.
Single core performance is important. If the node is falling behind and a single core is 100% busy, it is recommended to update to a faster processor
The minimum storage requirements will change over time as the chain grows. Using more than the minimum requirements to run a robust full node is recommended.
Download and install Docker, ensure it is running.
Unlimited rate limit Ethereum RPC endpoint and beacon chain RPC endpoint
Specify a local path to store data for running the node, determine the EigenDA Nitro version, and then execute it.
The node should now be running and looking for peers to sync.
For a more detailed node run instruction, please refer to this link. https://github.com/hpp-io/node
HPP generates blocks only when there are transactions to process. So if you don't see new blocks coming in, it just means there's no transaction activity - your node is still syncing correctly.
