IPPAN - Immutable Proof & Availability Network
A next-generation blockchain built for speed, reliability, and human usability. IPPAN combines HashTimer™ deterministic time ordering with BlockDAG consensus to deliver sub-second finality, human-readable addresses, and million-TPS throughput for the future of decentralized AI.
Why IPPAN
Speed, order, and availability—by design
IPPAN reimagines blockchain technology for real-world applications. Unlike traditional blockchains that struggle with speed and usability, IPPAN delivers AI-grade performance through innovative BlockDAG consensus and HashTimer™ deterministic time ordering. This combination ensures sub-second finality, human-readable addresses, and enterprise-ready reliability for the next generation of decentralized AI applications.
- Lightning Fast: 10-50 ms block frequency with 100-250 ms finality for real-time applications
- Human-Friendly: Easy-to-remember @handle.ipn addresses instead of complex cryptographic strings
- Decentralized Storage: Built-in DHT with content-addressed storage for reliable data availability
- Cross-Chain Ready: Seamless integration with other blockchains through proof anchoring
HashTimer™
Verifiable time & deterministic ordering
HashTimer™ solves one of blockchain's biggest challenges: achieving consistent time ordering across a decentralized network. By embedding consensus-derived time snapshots into every transaction, block, and round hash, HashTimer ensures that all network participants agree on the exact sequence of events, regardless of individual machine clock variations. This breakthrough technology enables deterministic ordering and fast finality even in the most challenging network conditions.
HashTimer := H(network_median_time || entropy || tx_header) RoundHash := H(HashTimer || DAG_parents || merkle_root) BlockHash := H(HashTimer || tx_root || validator_sig)
Core Technology Stack
BlockDAG • HashTimer • DHT • Cross-Chain
BlockDAG (Roundchain)
Revolutionary consensus mechanism that enables parallel block production and validation. Validators work in coordinated rounds to achieve unprecedented throughput while maintaining security and decentralization.
HashTimer™
Verifiable time & deterministic ordering across the network. Embeds consensus-derived time snapshots into every transaction, block, and round hash for consistent event sequencing.
DHT & Storage
Distributed Hash Table provides content-addressable storage with global discovery capabilities. Built-in micro-cost anti-spam mechanisms ensure network availability and prevent abuse.
Cross-Chain Anchors
Seamless interoperability with other blockchains through secure proof anchoring. External chains can commit Merkle roots or zero-knowledge proofs to IPPAN for trusted time-stamping and finality guarantees.
L2 Architecture
Minimal L1 with smart contracts on L2. Supports ZK rollups, optimistic rollups, and app-chains while maintaining L1's ultra-fast performance. Enables arbitrary programmability without compromising core layer speed.
NAT Traversal
Advanced networking with UPnP, NAT-PMP, and AutoNAT technologies ensures reliable peer-to-peer connections across any network configuration without manual setup requirements.
Cryptography
State-of-the-art Ed25519 signatures with human-readable base58i addresses (starting with i...). Post-quantum ready extensions ensure long-term security.
Ecosystem Modules
Everything you need to build & use
Wallet & Finance
Complete digital wallet solution with send/receive functionality, balance management, account creation, machine-to-machine payments, and QR code support for seamless transactions.
@handle.ipn Domains
Revolutionary human-readable identity system (e.g., @alice.ipn) that replaces complex addresses. Update fees contribute to network sustainability and community development.
Storage & Discovery
Decentralized storage with HashTimer-based file identification. Built-in integrity verification and handle support ensure reliable data availability and discovery.
Cross-Chain Gateway
Universal bridge for blockchain interoperability. Securely anchor external state from other chains using Merkle proofs and zero-knowledge verification for trusted cross-chain operations.
Availability Economics
Innovative incentive system with 0.1% commission rewards for continuously online nodes. Weekly mints ensure fair distribution and encourage network reliability.
Light Mining
Energy-efficient participation model with daily limits that encourage broad network participation while maintaining sustainability and preventing centralization.
Build on IPPAN
Quickstart & network economics
# 1) Clone & build
$ git clone https://github.com/ippan-labs/ippan && cd ippan
$ cargo build --release
# 2) Run a local devnet (3 validators)
$ cargo run --bin devnet -- up --validators 3
# 3) Create an address (base58i -> starts with i...)
$ cargo run --bin addrtool -- new --name alice
# 4) Send a payment (example)
$ curl -X POST http://localhost:8080/v1/tx/send -H 'Content-Type: application/json' -d '{ "from":"i...", "to":"@bob.ipn", "amount":"1.25", "memo":"thanks" }'1 IPN per block; 20% to creator, 80% to verifying validators.
Continuously online nodes share a weekly pool. 0.1% commission funds reliability.
@handle.ipn updates require fees; premium TLDs (.cyborg, .humanoid, .iot, .m) renew annually.
Peer discovery under extreme conditions; micro-costs harden against malicious availability spam.
Figures are design goals; performance depends on network conditions and implementation maturity.
