Under the hood, Fairsharecoin is engineered for simplicity, longevity, and trust — at global scale.
Fairsharecoin transactions are modeled after email — human-readable, lightweight, and asynchronous. Each wallet is linked to an email address (encrypted) and each transaction message resembles a message being sent: from sender to recipient.
Behind the scenes, full nodes manage delivery, encryption, verification, and ledger logging. The system also encourages responsible usage: fractional sending is recommended, starting with picos or nanos — especially during times of need. For users, it feels as simple as typing a message and hitting send — but for value.
Every full node keeps a verified, signed ledger of all transactions. These nodes sync periodically. Light nodes (or mobile clients) don’t need the entire ledger, just enough for current balances.
Syncing is optional but encouraged — helping keep the network decentralized and strong. Nodes that fall out of sync can rejoin by verifying the latest Merkle tree snapshot.
To maintain fairness and prevent spam or abuse, outbound transactions are rate-limited per sender. Verified wallets and anonymous ones are both limited — by frequency, not amount. This allows legitimate high-value transfers while discouraging micro-spam.
Limits may scale based on behavior, trust score, or community stake voting in future protocol versions.
This system maintains open access while remaining resilient against volume-based attacks or annoyance tactics.
Transactions are processed by the network and delivered like mail — simple, permanent, and trustable.
Fairsharecoin ensures that each coin is issued once — and only once — by anchoring issuance to a verified human identity. This is done via a cryptographic hash known as COINMINT_ID, derived from the user's ICAO-compliant ePassport.
These biometric passports contain secure embedded chips that can be read and verified offline using ICAO public certificates. The resulting `COINMINT_ID` is consistent across passport renewals and contains no personally identifying data — only proof of uniqueness.
As digital ePassports (DTCs) are deployed globally, Fairsharecoin will support them as a modern, mobile-native identity anchor. This allows future users to claim their coin using just a smartphone, while maintaining the same level of cryptographic security.
To keep transactions fast, even with a growing history, FSC introduces KEYMINT — lightweight signing keys derived from the original COINMINT.
Users may have up to 10 active KEYMINTs at a time. Transfers may trigger auto-renewal without user intervention. Each COINMINT is derived from the holder’s ICAO ePassport — a biometric, cryptographically signed document that guarantees global uniqueness. As digital ePassports (DTCs) roll out, FSC will integrate them to enable mobile-native identity claims. Renewing a passport does not break identity. COINMINT logic ensures that your unique identity hash persists — keeping your coin, balance, and transaction history intact. Privacy, resilience, and fairness — by design.
Fairsharecoin allows users to regain access to their wallet even if they lose their email or GPG key — without issuing a new FSC. Recovery uses the original COINMINT_ID (derived from their verified identity), not email or device credentials.
To prevent value lock-up from permanently lost or deceased accounts, Fairsharecoin supports a global fairness lifecycle. If a wallet linked to a COINMINT_ID remains untouched beyond a set period — for example, 15 years — the network may begin a redistribution process.
This mechanism preserves long-term fairness, gently introduces natural deflation, and encourages periodic wallet renewal or relinking. The system rewards activity and prevents permanent hoarding through forgotten or abandoned accounts.
Fairsharecoin’s architecture is designed to scale globally — without overwhelming full node operators. Two core techniques keep the ledger light and sustainable:
| User Base | Estimated Storage | Notes |
|---|---|---|
| 1 million | ~5 GB | Global ledger, minimal indexing |
| 21 million | ~105 GB | Compact metadata model |
| 100 million | ~500 GB | Light transaction metadata only |
| 1 billion | ~5 TB | No raw history, pruned node model |
| 10 billion | ~50 TB | Fully pruned, global scale |
If the ledger is divided into 100 shards, each node only stores 1% of the global state — keeping things light even at global scale.
| User Base | Storage per Shard |
|---|---|
| 1 million | ~50 MB |
| 21 million | ~1.05 GB |
| 100 million | ~5 GB |
| 1 billion | ~50 GB |
| 10 billion | ~500 GB |
With pruning and sharding combined, full node storage becomes manageable — even for planetary-scale adoption. Future nodes may also choose to only store recent years and rely on signed Merkle snapshots for deep history, making ultra-light participation possible.
Fairsharecoin is not just efficient in terms of storage — it also minimizes CPU and bandwidth usage. Here's what FSC would require at various scales, assuming each user makes around 10 transactions per year.
| User Base | Yearly Transactions | Total Storage | Bandwidth per Full Node (year) | CPU per Full Node (year) |
|---|---|---|---|---|
| 1 million | 10 million | ~2.5 GB | ~256 MB | ~33 seconds |
| 21 million | 210 million | ~52.5 GB | ~5.4 GB | ~11.6 minutes |
| 100 million | 1 billion | ~250 GB | ~25 GB | ~55 minutes |
| 1 billion | 10 billion | ~2.5 TB | ~250 GB | ~9.2 hours |
| 10 billion | 100 billion | ~25 TB | ~2.5 TB | ~3.8 days |
These numbers show how radically lightweight FSC is, even at humanity-scale. Most full nodes — even those handling millions of transactions — could run on old laptops, mini PCs, or modest VPS servers. Low power, low bandwidth, high fairness.
From one identity to one coin — every layer of FSC reinforces the same idea: fairness, enforced by design.
