Thesis

Holy Grail of Crypto
Most blockchains are pseudonymous at best — every transaction permanently visible on a public ledger. Stealth offers something categorically different: a fast, feeless, private protocol with a dedicated zk-SNARK sidechain — where sender, receiver, and amount are hidden by mathematics, not by policy. XST on stealthCORE delivers the feeless, sub-5s base layer; XSS on stealthPRIVATE closes the privacy gap as a shielded-by-default moat.

The Seven Tenets

What makes Stealth different
01

The only BTC descendant with true feeless transactions.

Feeless enables microtransactions below a cent — streaming payments, per-minute billing, on-chain voting where ballots are fully recoverable.

Fee · $0.00
02

First feeless multisignature transactions in crypto.

A native primitive, not a smart-contract approximation. Custodial applications that require multisig no longer pay for every signature.

Native · Protocol-level
03

The only fee-optional cryptocurrency, anywhere.

Feework outputs substitute for fees. Users freely choose between paid and free transactions. Paid transactions get priority under load.

Mode · Elective
04

Deterministic 5-second blocks, consistently.

Junaeth organizes validators into a signing queue with fixed windows. There is no competition, no variance — just schedule.

Interval · 5.00 ± 0.0s
05

Throughput competitive with Visa, from a single CPU.

917 TPS baseline. Concurrent verification scales to ~150,000 TPS on 16-core hardware. Blocksize is an elastic parameter.

Peak · ~150k TPS
06

The best spam resistance of any feeless coin.

Network-time feework expiration caps abuse without compromising UX. No coin has fewer attack surfaces in the feeless category.

Vectors · Minimal
07

Cryptographic privacy — mathematical, not probabilistic.

Opt into the stealthPRIVATE sidechain; once there, every transaction is shielded by zk-SNARK proof. No decoys, no obfuscation, no statistical arguments.

The Trilemma

Decentralisation · Security · Scalability
The blockchain trilemma, framed by Vitalik Buterin, argues that a chain can optimise for only two of three properties simultaneously — decentralisation, security, scalability. Every major chain makes the trade-off. Stealth refuses.
Leg 01

Decentralisation

No central authority. Permissionless participation. No single point of failure or control. The founding promise of blockchain — and the first thing most high-performance chains quietly sacrifice.
Leg 02

Security

Resistance to attacks, immutability, and Byzantine fault tolerance. A chain that can be rewritten, halted, or censored by a small group is not secure — no matter how fast it is.
Leg 03

Scalability

High throughput, fast finality, low latency. The ability to handle real-world transaction volumes without degrading performance or pricing out users with fees.

Scalable ~
Trilemma solved

Most high-performance chains achieve scalability by centralising the validator set — Solana relies on a relatively small set of high-spec validators. Speed comes at the cost of decentralisation and, ultimately, security.

Junaeth's economic validator selection — where rights are purchased and rewards are purely merit-based — creates a stable, self-regulating validator set of 100 StealthNodes. No voting. No politics. No foundation deciding who validates. The economics do the work.

Bitcoin-grade security and decentralisation principles alongside 5-second blocks, 917 TPS base throughput, and a feeless transaction model — all three corners of the trilemma addressed simultaneously.

"Junaeth has been developed to support smart contracts, sidechains, on-chain governance, and blockchain oracles. Stealth is also unique in that it is fee-optional, with the most spam resistant feeless protocol yet invented."

Junaeth Consensus

Queue · Economic · Deterministic
6.1

The Queue

Scheduling
Pseudorandom queue.
One slot per node.
Five seconds, always.

Junaeth organises every StealthNode into a signing queue with a fixed 5-second window per slot. Every node gets exactly one slot per round — the ordering within the round is pseudorandom, not reputation-weighted. A block signs every 5 seconds, forever.

The network currently consists of 100 StealthNodes. The next node cannot sign until the current window closes. There is no PoW race, no fee auction, no MEV.

The result is a blockchain that ticks like a metronome, not like a slot machine.

Economic Bonding

One-way · Lifetime
Buy your rights.
Bids are burned.

StealthNodes are purchased from the blockchain by irreversibly burning XST. The XST spent on a bid is permanently destroyed — removed from the money supply, never recycled to a foundation, validator, or treasury.

Pricing uses a reverse auction. Instances are offered one at a time, each more expensive than the previous. Bids are transparent and binding — each valid bid irreversibly claims one StealthNode. Buying stops when the next bid is too expensive to justify; that last price estimates market equilibrium.

Two forces balance the auction: each purchase shrinks the XST supply, and each new validator dilutes the share of a fixed reward pool. The set naturally stabilises — no governance, no votes, no cabal.

Reputation Weighting

Compounding · Continuous
Weight =
√(produced − missed)

Every StealthNode gets one slot per round — all 100 sign equally in rotation. Rewards, however, are not equal. The fixed reward pool is split among nodes by weight, where weight equals the square root of (blocks produced minus blocks missed).

The square root shape is deliberate. New nodes can partially catch up to long-running ones at equivalent performance, but they can never fully overtake a node that has been well-performing for years. A temporary performance drop is permanent in its effect: the missed block is gone, and it reduces the weight multiplier on every block earned thereafter.

Weight also determines consensus influence. When a StealthNode produces a block, it casts a weighted vote for that chain. The chain with the highest cumulative vote weight wins fork resolution.

Target block interval · 5.000s Observed · 5.0116s Missed blocks per 24h · ~0.2%

Network Timekeeping

Byzantine-tolerant
Blocks are
the clock.

A globally synchronised clock across a heterogeneous network is impossible — latencies are unpredictable, and polling other nodes for "what time is it" is itself subject to those latencies. Junaeth sidesteps the problem entirely.

Time is kept by the blocks themselves. Each block carries a height exactly one greater than its predecessor — block heights are the ticks of Junaeth's network clock. An isolated validator keeps producing blocks regardless; it doesn't need to know whether it's isolated or the rest of the network is.

Fork resolution uses focal point game theory: a node on a minority branch eventually reorganises to the winning chain, not because of timestamps, but because building on a chain no one else is building on costs it reward weight on the winning chain and accumulates missed blocks on the losing one. Economics resolves what timestamps can't.

Economic Model

Junaeth Economics · XST

Buy your rights.
Earn by performing.
No committee of insiders.

Junaeth prices validator entry through a reverse auction, funds rewards from a fixed pool, and weights earnings by square-root of net blocks produced. Validation rights are purchased, not granted.

Weight formula
√(P − M)
Source: stealth.org · Junaeth four-part series. The reward pool does not grow with the validator count — adding validators dilutes the share rather than expanding issuance.
01 · StealthNode Purchase

Reverse auction, binding bids.

Validators are not elected, voted in, or granted. They are purchased. StealthNodes are offered one at a time, each more expensive than the previous. Bids are transparent and binding — each valid bid irreversibly claims one node. The auction stops when the next bid becomes too expensive to justify; that last price estimates market equilibrium.

02 · Permanent Burn

Bid funds are destroyed.

XST spent on a StealthNode purchase is not collected by a foundation, a validator, or a treasury. It is permanently eliminated from the money supply — never recycled. Every new validator reduces total XST supply at the moment of purchase.

03 · Fixed Reward Pool

Dilution, not expansion.

All StealthNodes share a fixed reward pool that does not grow with the validator count. Adding more validators shrinks each share proportionally. This is why the validator set naturally stabilises rather than expanding indefinitely — new StealthNodes eventually become too expensive to justify buying.

04 · Weight by √

Performance compounds, permanently.

A StealthNode's weight equals the square root of (blocks produced minus blocks missed). Weight determines both reward share and consensus vote weight during fork resolution. The square-root shape lets new nodes partially catch up at equivalent performance, but prevents them from ever fully overtaking long-running well-performing nodes. A temporary performance drop reduces every future block earned.

05 · Feework, Not Fees

Compute burned instead of money.

Users transact feelessly by attaching a feework proof — a memory-hard Argon2d computation bound to the specific transaction and a recent block height. Feework expires after 24 blocks (two minutes), which caps spam accumulation. Paid transactions receive processing priority under burst load, making the protocol fee-optional rather than fee-free.

§ 08

stealthPRIVATE

Privacy by mathematics
XSS · Dedicated Sidechain · zk-SNARKs · Halo 2 / Orchard

Opt in at the bridge. On the sidechain, every transaction is shielded. No mixed mode.

01 / Bridge In

XST on stealthCORE is locked in a 2-of-3 multisig P2SH address; an equivalent amount in XSS is minted on stealthPRIVATE as a shielded note. The deposit record stores the locking txid, amount, and staker keys — but never stores the sender address or receiver shielded address. The bridge is opt-in; it is also the only way onto the private chain.

02 / Shielded Pool

Inside stealthPRIVATE, funds exist as encrypted notes. Every transfer is shielded-to-shielded using Halo 2 zk-SNARK proofs. Sender, receiver, and amount are hidden at every step. No rich list, no transaction explorer, no metadata leak — the sidechain is pool-based with no per-user linkage between deposits and withdrawals.

03 / Bridge Out

Withdrawal destinations are a parameter you specify. Any XST address, any amount up to an available deposit UTXO — with zero enforced linkage between who deposited and who withdrew. stealthCORE can be hosted independently of the sidechain, so exchanges and custodians can run stealthCORE alone without ever touching shielded transaction data.

Applications

Built on the protocol
9.1

Machine payments — the x402 protocol

APP / 03 · deep dive

x402 is an open payment protocol built on top of HTTP, leveraging the long-dormant 402 Payment Required status code — reserved in 1991 “for future use” and never implemented. Until now.

The model has one hard requirement — the payment layer must not add friction. A $2 fee on a $0.001 API call makes the entire model economically absurd. Speed matters too: an AI agent waiting ten minutes for block confirmation is a broken agent. And when autonomous systems transact sensitive data on users' behalf, privacy stops being optional.

Stealth satisfies all three conditions simultaneously — feeless transactions protected by memory-hard feework instead of fees, 5-second blocks matching machine latency budgets, and the stealthPRIVATE zk-SNARK sidechain for behavioural privacy between agents. No other chain does all three today.

Server returns 402

STEP 02

Roadmap

From 2-Way to 4-Way Hybrid Ledger
2014Genesis

Stealth mainnet launches

Dedicated blockchain — a Bitcoin descendant with novel feework and multisig primitives. Open source from day one.

2021Junaeth Live

Junaeth consensus activated on mainnet

Queue-based StealthNode validators, deterministic 5-second blocks, reverse-auction validator pricing, square-root weight rewards. The current live consensus.

Nowv3.2.1.5

Phase 1 shipped — 2-Way Hybrid Ledger

UTXO Bitcoin Ledger (transaction history) fused with Registry Ledger (block rewards, stealth addressing). Feeless transfers, feework spam resistance, and stealthPRIVATE shielded sidechain are all in production today.

Phase 2In Progress

Account Ledger — General Purpose state

Extending the Registry Ledger technology into a stateful Account Ledger. Enables account-based balance tracking alongside the existing UTXO model — laying the groundwork for smart contract state.

Phase 3Upcoming

Smart Contract Layer

A fourth ledger — programmable, stateful, and extensible. Active research on whether contract execution can be made feeless via a PoW mechanism (caller burns compute rather than paying fees). Hybrid fee model is the likely fallback.

Phase 4Vision

Full Extensibility — 4-Way Hybrid Live

All four ledgers operational simultaneously: UTXO for transfer finality, Registry for rewards, Account for state, Smart Contracts for programmable logic. AI-native payments, DeFi primitives, programmable micropayments — feeless at the transfer layer.
