+This repository uses an ephemeral Protocol v2 devnet as a pull-request correctness gate. + +The gate is designed to catch regressions that package-level unit tests can miss: real QUIC/libp2p connectivity, transaction delivery, scheduled proposal, validator voting, quorum-certificate construction, finalized commit and non-validator state convergence. + +## Pull-request topology + +The default pull-request run has two layers: + +- a correctness scenario with 7 Protocol v2 validator nodes, 1 non-validator full observer and 1 transaction client; +- a large validator-set smoke scenario with 20 Protocol v2 validators plus the same observer/client roles for transaction delivery and finalized consensus. + +All nodes use the real Protocol v2 libp2p transport on loopback QUIC addresses allocated by the GitHub-hosted runner. Each validator and the observer own an independent runtime and independent world state. + +The transaction client sends a signed native-token transaction through the Protocol v2 transaction stream to the scheduled proposer. Finality is accepted only after proposal verification, validator votes and a normal 2/3+ certificate. + +The gate verifies that: + +- the transaction reaches the proposer over the network transport; +- the scheduled proposer collects a 2/3+ quorum; +- every active validator commits the same finalized height; +- the non-validator observer applies the certified commit and materializes the same payment; +- the observer cannot propose or vote as a validator; +- with 2 of 7 validators offline, the remaining quorum can still finalize; +- with 3 of 7 validators offline, finality fails closed and no node commits. + +## Manual scaling + +The pull-request gate always runs the 7-validator correctness/fault scenario and a 20-validator transaction/finality smoke. The workflow also supports manual runs with the large validator-set count configurable from 4 through 20; the manual input defaults to 20. + +The quorum-fault boundary test remains fixed at 7 validators because it explicitly checks the 5-of-7 quorum boundary. + +## GitHub-hosted topology boundary + +These are real Protocol v2 nodes and real QUIC/libp2p connections, but the current gate places them on one standard GitHub-hosted Linux runner. + +That is intentionally different from the in-memory finality harness, and it is useful for process/network-stack correctness, but it is still not a geographically distributed production network. + +A later phase can place nodes on separate GitHub jobs once an authenticated zero-cost inter-runner rendezvous/transport is available.

Use finalized consensus resource consumption. - -Blockchain resource utilization and compute-market utilization are separate signals and must not be conflated. - -### Finalized operations - -Operation counts are secondary signals only. They are not sufficient alone because an attacker can generate economically meaningless activity. - -### Age-weighted monetary velocity - -Simple transfer volume is wash-tradeable. Zephyr v2 coin objects now carry a consensus-stamped `CreatedHeight`. - -New coin outputs are rewritten by deterministic execution with the candidate block height, so the wallet cannot choose an old timestamp to create fake monetary age. - -The reference velocity accumulator uses: - -```text -age = spendHeight - CreatedHeight -``` - -with configurable minimum age, full-weight age and maximum velocity bounds. - -Rapidly recreating and cycling fresh coin objects therefore resets their age and can contribute zero below `MinAgeBlocks`. - -Unknown/genesis age (`CreatedHeight = 0`) is tracked separately and excluded by the current reference policy. - -## 5. Zephyr normalized compute work - -There is no honest universal scalar that makes every CPU, GPU, AI training job, renderer and scientific workload directly equivalent. - -Zephyr therefore uses a **resource vector**, not a fake universal FLOP count. - -The current model includes: - -```text -CPUUnits -GPUFP32Units -GPUFP64Units -TensorUnits -MemoryByteSeconds -VRAMByteSeconds -StorageBytes -NetworkBytes -``` - -A standardized workload definition carries protocol version, workload class, normalized units, workload hash, benchmark/specification hash and resource vector. - -The benchmark hash anchors the meaning of the units. A provider cannot make its hardware appear more valuable merely by self-reporting a larger number. - -## 6. Compute workload registry - -Only standardized work specifications are eligible for monetary telemetry. - -A registry entry binds: - -```text -WorkloadHash - -> WorkClass - -> normalized Units - -> WorkVector - -> BenchmarkHash -``` - -Conflicting definitions for the same workload hash are rejected. - -The current registry is a reference implementation. Before monetary activation it must become authenticated/governance-controlled state with delayed versioned activation. - -## 7. ZCPI — Zephyr Compute Price Index - -ZCPI is an internal Zephyr compute-market price index. It is **not** a CPI and is not a claim about real-world inflation. - -It answers: - -> how many atomic ZPH units were actually paid for standardized, verified compute work on Zephyr? - -ZCPI excludes: - -- advertised provider prices; -- unfilled offers; -- self-reported theoretical FLOPS; -- failed/unverified jobs; -- arbitrary unregistered workload units. - -Eligible observations derive from: - -```text -registered workload spec -+ finalized compute job -+ verification-satisfied result -+ actual on-chain provider payments -``` - -The reference implementation uses fixed-point Q9 arithmetic, per-class medians, EWMA smoothing, basket coverage and an explicit reliability flag. - -## 8. ZCSI — Zephyr Compute Scarcity Index - -ZCPI alone cannot safely drive inflation. A price increase can reflect scarcity, demand growth, ZPH purchasing-power movement or workload-mix changes. - -Zephyr therefore separately computes **ZCSI**, a bounded scarcity score based on: - -```text -escrow-backed standardized demand -verified standardized supply -funded backlog -fulfilled work -compute utilization -reliable ZCPI price trend -``` - -Only real escrow-backed standardized work counts as demand. Provider-advertised capacity does not become verified supply merely because it is claimed. - -If ZCPI is unreliable, the price component is removed. If demand/supply coverage is too thin, ZCSI itself becomes unreliable. - -An unreliable ZCSI is prohibited from changing either compute reward routing or the monetary target in the shadow evaluator. - -## 9. Compute feedback experiments A/B/C - -The branch implements three **shadow-only** modes. - -### A — observe only - -```text -ZCSI -> telemetry only -compute reward share -> unchanged -inflation target -> unchanged -``` - -### B — reward routing - -```text -ZCSI -> suggested compute reward share -inflation target -> unchanged -``` - -This is the preferred first candidate if devnet evidence eventually justifies activation. Scarce verified compute can receive a larger share of an already-defined issuance budget without changing total issuance. - -### C — reward routing + narrow monetary band - -```text -ZCSI -> suggested compute reward share -ZCSI -> small bounded shadow inflation correction -``` - -The total-inflation sensitivity is deliberately much smaller than the reward-routing sensitivity. - -Mode C must demonstrate a material stability/capacity benefit over Mode B before it is considered for activation. - -The current active economic boundary remains equivalent to Mode A: **no compute signal changes live supply**. - -## 10. Native ZPH fee accounting - -V2 execution requires native ZPH inputs to cover outputs plus the signed fee. - -The reference fee engine now supports: - -```text -resource charge - | - +-- burn - +-- validator/reward pool - +-- protocol reserve -``` - -with integer basis-point splits and deterministic rounding that conserves every atomic unit. - -Until state-backed distribution is activated, the compatibility policy preserves the current effective 100% fee burn. - -## 11. Smart-contract gas - -Contract execution reports deterministic `FuelUsed` and enforces `FuelLimit`. - -The reference resource fee model can include: - -```text -base transaction charge -+ signature work -+ witness bytes -+ state reads/writes -+ FuelUsed * FuelPrice -+ DA bytes -+ cross-shard receipts -``` - -Final production prices and the active base-fee controller remain simulation/benchmark decisions. - -## 12. Compute payment is not blockchain gas - -Heavy compute has two independent prices: - -```text -provider payment -+ blockchain settlement fee -``` - -A 100 ZPH AI job does not imply 100 ZPH of gas. Validators settle commitments/proofs/results; they do not replay the expensive workload. - -## 13. Native custom-token policy - -Protocol-native custom assets now have explicit supply policies: - -```text -FIXED -CAPPED -MINTABLE -``` - -The v2 executor implements: - -- custom-token creation; -- `MintToken` with mint-authority and cap enforcement; -- `BurnToken` with burn-permission enforcement; -- authenticated `TokenDefinition.CurrentSupply` updates; -- `Transferable` enforcement; -- read-only token-definition policy witnesses for parallel normal transfers. - -ZPH itself is excluded from user-authority mint/burn paths. Future ZPH issuance can occur only through an explicitly activated protocol monetary transition. - -Custom-token cross-shard transfer/mint is deliberately gated until a globally verifiable token-policy proof/registry is available. - -## 14. Economic epoch state - -Zephyr must not create one global monetary object touched by every transaction; that would serialize execution. - -The current foundation therefore uses: - -```text -finalized execution - -> per-shard epoch metrics - -> deterministic epoch aggregate - -> shadow MonetaryEpochState -``` - -Per-shard metrics cover: - -- charged/burned/validator/reserve fees; -- finalized operations; -- chain resource used/capacity; -- shard circulating ZPH; -- age-weighted velocity; -- escrow-backed compute demand; -- verified compute supply; -- compute backlog/fulfillment. - -Exact fee conservation is validated. - -Global velocity is weighted by per-shard circulating ZPH rather than giving every shard equal influence. - -Chain resource utilization and compute utilization are calculated separately. - -The canonical aggregate hash is committed by a deterministic shadow `MonetaryEpochState` system object. Consecutive states bind `PreviousStateHash`. - -The object can enter the normal Sparse-Merkle state root through consume/recreate semantics, so a future epoch-boundary runtime transition does not require another special consensus root. - -The current transition builder returns a state delta for pre-QC simulation; it does not commit a store itself. - -## 15. Testing and replay - -The branch includes deterministic tests for: - -- normalized work-spec serialization and registry conflicts; -- verified settlement observations; -- ZCPI medians, coverage, reliability and trend bounds; -- ZCSI demand/supply scarcity and reliability fail-closed behavior; -- A/B/C feedback separation; -- burn offset and rate-limited ZAMP target; -- fee split/resource quotation conservation; -- consensus override of wallet-provided coin creation height; -- old versus fresh age-weighted velocity; -- rapid self-cycling suppression; -- per-shard economic accounting and multi-shard aggregation; -- separation of chain and compute utilization; -- canonical shadow monetary state and previous-epoch binding; -- suggested Mode-C mint remaining shadow while `TotalSupply` is unchanged. - -`cmd/zephyr-econ-sim` supports base ZAMP replay and optional compute-market/ZCSI A/B/C inputs. See `docs/examples/zephyr-econ-sim-compute.json`. - -## 16. Activation gates - -ZAMP remains shadow-only until all of the following are true: - -1. per-shard economic metrics are derived automatically from finalized runtime execution rather than caller-provided summaries; -2. fee distribution is state-backed and conserves supply exactly; -3. verified compute supply comes from authenticated benchmark/availability state; -4. velocity is stress-tested against long-horizon self-cycling and capital-lock attacks; -5. all monetary metrics are reproducible from finalized state; -6. long simulations cover usage shocks, partitions, validator churn, spam, compute booms/busts and oscillating adversarial inputs; -7. parameter sensitivity does not create runaway or oscillatory issuance; -8. governance can change parameters only through bounded delayed transitions; -9. Citizen Nodes can decode and independently verify monetary state/history; -10. ZCPI/ZCSI have sufficient real-market coverage before Mode B or C is considered; -11. an emergency deterministic fallback can zero adaptive corrections when required metrics are unavailable/invalid; -12. live mint/reward/fee distribution has an explicit protocol-version/activation-height transition. - -## 17. Current policy boundary - -The branch implements **measurement, authenticated shadow state and shadow decisions**, not live monetary issuance. - -The design principle remains: - -```text -measure first -simulate second -activate last -``` - -This lets Zephyr develop an adaptive oracle-free economy without turning monetary policy into an untested consensus experiment. +This documentation reflects **Zephyr Chain — Protocol Economics, Monetary Design, Governance, Lending and Consensus Incentives, working whitepaper v0.1 (19 Aug 2026)** together with the current Protocol v2 P1 implementation state. diff --git a/internal/v2/consensus/certificate_binary.go b/internal/v2/consensus/certificate_binary.go new file mode 100644 index 00000000..8f2294fd --- /dev/null +++ b/internal/v2/consensus/certificate_binary.go @@ -0,0 +1,7 @@ +package consensus + +// MarshalCertificate is the functional counterpart to ParseCertificate and +// preserves the existing Certificate.MarshalBinary canonical encoding. +func MarshalCertificate(c Certificate) ([]byte, error) { + return c.MarshalBinary() +} diff --git a/internal/v2/economics/compute_capital_components.go b/internal/v2/economics/compute_capital_components.go new file mode 100644 index 00000000..acbdd7b5 --- /dev/null +++ b/internal/v2/economics/compute_capital_components.go @@ -0,0 +1,109 @@ +package economics + +import ( + "bytes" + "math" + "sort" + + "github.com/zephyr-chain/zephyr-chain/internal/v2/compute" + "github.com/zephyr-chain/zephyr-chain/internal/v2/types" +) + +type ComputeCapitalComponentKind uint8 + +const ( + ComputeCapitalComponentUnknown ComputeCapitalComponentKind = iota + ComputeCapitalComponentEscrow + ComputeCapitalComponentCollateral +) + +// ComputeCapitalComponent is a stable shadow identity for one economically +// distinct portion of native capital held by a compute job.
