Spearmint (SPMTC) — Preliminary Technical Comparison Meeting Notes

Date: October 26, 2025 • Type: Comparison session (no decisions)

Purpose: compare and contrast Spearmint’s current technical/economic direction against patterns used by top‑20 crypto assets. This is a comparison meeting, not a decision meeting.

1) Scope & Objectives

2) Transparency & Verifiability

3) Current SPMTC Direction (baseline for comparison)

3.1 Protocol

  • Consensus: Proof‑of‑Work (SHA‑256), Bitcoin‑Core‑derived.
  • Block target: 30s (≈1,051,200 blocks/year).
  • Difficulty: ADR (Aggressive per‑block retargeting) to contain short‑horizon hash spikes.
  • Finality policy: DBF — elevated confirmation depth for high‑value settlement.
  • Mining pools: ckpool‑style transparency; exportable telemetry.

3.2 Monetary Policy

  • Total supply: ~210,000,000 SPMTC (fixed).
  • Genesis issuance: block reward 50 SPMTC.
  • Halving schedule: accelerated ~6‑month halvings for ≈5 years → annual halvings (longevity phase).
  • Pre‑launch acquisition: 8% via provable solo mining; details published in the Proof Log.
  • Fees: standard PoW transaction fees to miners; no base‑fee burn.

4) Comparison Highlights — SPMTC vs. Top‑20 Patterns

Dimension SPMTC (baseline) Common Top‑20 Patterns Implications / Notes
Consensus PoW (SHA‑256) PoS prevalent; fee burns (EIP‑1559‑style) SPMTC avoids usage‑linked deflation; relies on hash‑based security and fee market.
Supply Policy Fixed cap ~210M; accelerated → annual halvings Mix of caps + burns; some uncapped with burns Cap provides scarcity; absence of burns trades off elasticity for simplicity and auditability.
Block Cadence 30s target; ADR + DBF Varies; faster L1s often PoS Faster PoW requires careful reorg economics; ADR reduces exploit windows.
Distribution 8% pre‑launch via solo mining; 92% via mining emissions Escrows, treasuries, large airdrops common Proof Log + signed artifacts emphasize verifiability vs. discretionary unlocks.
Fee Treatment Fees → miners; no base‑fee burn Burns widely used (ETH/BNB/AVAX) No usage‑driven supply sink; simpler accounting; miner‑only accrual.
Governance Code‑driven, releases signed; no token‑weighted governance implied On‑chain governance and treasuries common Minimizes governance attack surface; fewer levers for monetary discretion.

5) Risk & Attack Surface (technical)

Suggested mitigations

6) Measurement & Monitoring

Core KPIs

  • Blocks/day, orphan rate, average reorg depth, variance bands.
  • Hash‑rate delta (1h, 6h, 24h), pool Gini/Nakamoto coefficient.
  • Issuance per epoch, cumulative supply, miner revenue (fees vs. subsidy).

Dashboards

  • Real‑time supply and halving countdowns.
  • Difficulty/ADR response visualizations.
  • Pool share and centralization monitors.
