PHONCOIN Bible

A canonical technical bible for PHONCHAIN: network identity, consensus, security model, tokenomics, and public endpoints. Everything here is meant to be verifiable.

Phoncoin does for phones what Bitcoin did for CPUs in 2009 — turning everyday devices into participants.

1 · Identity

PHONCOIN (PHC)

Native asset of PHONCHAIN
Mobile-first monetary network
Secured by real smartphones
Fair distribution — no privileges

PHONCHAIN

Public blockchain designed for mobile
Consensus: Proof-of-Phone (PoP Secure v4.1)
Crypto: Ed25519 + SHA-256
Open endpoints: API / gateway / explorer

2 · Consensus Proof-of-Phone Secure v4.1

Core idea

1 real phone = 1 participant
No heavy Proof-of-Work
No Proof-of-Stake based on wealth
Security comes from cryptography + hardware uniqueness + protocol checks

What a phone does

Generates an Ed25519 keypair
Sends signed heartbeats (activity proofs)
Solves a light PoW puzzle (difficulty target)
Attaches a hashed device fingerprint + device_info v4

What a node verifies

Ed25519 signature validity
Timestamp rules (anti-replay)
Difficulty target (light PoW)
Fingerprint binding & reuse detection
Security profile (emulator/root flags, trust score, rate limits)

3 · Security PoP-Secure v4.1 anti-fraud

Anti-emulator

Detects Android Emulator / Genymotion / suspicious environments
Immediate rejection when confirmed

Anti-root & trust score

Root detection signals
Trust score (0–100) computed on-device
Node policy rejects devices below the minimum threshold

Anti-cloning

Hashed device fingerprint (privacy-preserving)
Binding: 1 fingerprint → 1 address
Reuse is flagged and can be restricted

Anti-replay & rate limiting

Old/reused timestamps rejected
Heartbeats too close rejected (anti-spam)
Per-device and per-pubkey limits

Attestation ready

Device schema v4 includes a field reserved for Play Integrity / attestation verdicts
Protocol is designed to accept stronger attestations later without breaking compatibility

4 · Data model

Heartbeat (PoP-S4.1)

pubkey (Ed25519)
timestamp
nonce (light PoW)
signature
hashed device_fingerprint
device_info v4: OS, hardware, security flags, latency, trust score

Block

index, timestamp
prev_hash, hash
validated heartbeats
block reward
participating miner addresses

5 · Canonical network parameters

Target block time: 300 seconds (5 minutes)
Consensus: Proof-of-Phone (PoP Secure v4.1)
Algorithms: Ed25519, SHA-256
Ticker: PHC
Genesis block timestamp: 2025-10-09 08:53:20 UTCc098fa5e985edd56634af262975b771f0dadc607494d6875cb725f1006611658

6 · Tokenomics PHC

Total supply

Hard cap: 21,000,000 PHC

Block reward & halving

Initial reward: 25 PHC per block
Halving: every 420,000 blocks
Target block time: 5 minutes

Halving schedule (example)

Phase	Block height	Reward
Phase 1	0 – 419,999	25 PHC
Phase 2	420,000 – 839,999	12.5 PHC
Phase 3	840,000 – 1,259,999	6.25 PHC

Fair distribution

No premine
No ICO
No reserved team allocation
100% minted through real participation

7 · Wallet PHONCOIN Android

Principles

Non-custodial
Keys stored on-device only
No central server required

Security model (important)

The wallet never stores IPs
The wallet trusts only the canonical genesis_hash
Any endpoint with a mismatching genesis is rejected

8 · Public network architecture

Domains

phoncoin.org — official website, whitepaper, documentation
phonchain.org — public nodes: API, gateway/seed, explorer, bootstrap

Official endpoints

Bootstrap: https://bootstrap.phonchain.org/nodes.json
API: https://api.phonchain.org
Gateway/Seed: https://seed2.phonchain.org
Explorer: https://explorer.phonchain.org/explorer

9 · Bootstrap file nodes.json

Purpose

Provides an official list of public endpoints (HTTPS)
Allows wallets to evolve without app updates (priority/order can change)
Must include: network, mode, min_version, genesis_hash, nodes[] (url/role/region/priority)
Wallets should only select endpoints whose genesis_hash matches the canonical chain

10 · Principles

One phone = one voice
Security comes from real participation
Energy is precious → near-idle usage
No hidden privileges
Everything is cryptographically verifiable
