# Pelion > Bittensor Decentralized Adjudication for onchain contracts. ## Docs - [Architecture](https://docs.pelion.dev/how-it-works/architecture.md): Five layers, from application on Base to bonded cross-chain relay. The whole system in one page. - [Economic security](https://docs.pelion.dev/how-it-works/economic-security.md): Attack cost analysis, multi-subnet defense, and the quantitative comparison to UMA. - [Question lifecycle](https://docs.pelion.dev/how-it-works/question-lifecycle.md): From submit on Base to finalized payout. The state machine and edge cases. - [UNRESOLVABLE and calibration](https://docs.pelion.dev/how-it-works/unresolvable.md): Why genuinely ambiguous questions need a structural escape valve, not a forced binary resolution. - [Introduction](https://docs.pelion.dev/introduction.md): Bittensor Decentralized Adjudication for onchain contracts. - [UMA's structural failures](https://docs.pelion.dev/problem/uma-failures.md): Why token-weighted voting cannot produce reliable post-event adjudication when market stakes exceed the voter base's market cap. - [Why now](https://docs.pelion.dev/problem/why-now.md): Three independent trends that make a model-based adjudication protocol buildable in 2026. - [Full technical specification](https://docs.pelion.dev/reference/full-spec.md): The canonical Pelion technical specification, v0.1. - [Glossary](https://docs.pelion.dev/reference/glossary.md): Terms used across the Pelion documentation, specification, and source code. - [Canonical schemas](https://docs.pelion.dev/reference/schemas.md): Field-by-field reference for Question, Verdict, EvidencePolicy, and PelionSynapse. - [Governance](https://docs.pelion.dev/token/governance.md): Three-tier governance with quadratic voting, a council for disputed edge cases, and progressive decentralization. - [Token mechanics](https://docs.pelion.dev/token/mechanics.md): Trading tax with auto-decay. Buyback and burn funded by treasury Bittensor emissions. Utility tied to protocol usage. - [Treasury](https://docs.pelion.dev/token/treasury.md): How the treasury earns Bittensor emissions and converts them into Pelion token buyback and burn. - [Benchmark methodology](https://docs.pelion.dev/whats-built/benchmark-methodology.md): What Priority 1 will measure against 18 months of Polymarket historical markets, and what good looks like. - [Live example](https://docs.pelion.dev/whats-built/live-example.md): Install Pelion, set API keys, produce a real verdict. - [Repository and modules](https://docs.pelion.dev/whats-built/repository.md): Four Python modules, canonical schemas locked, multi-provider AI council operational.
