The ideas beneath CAST are not new in isolation. What is new is their combination — bilateral co-authorship, event sourcing, and cryptographic proof — applied to commercial payments at the moment AI makes verification the scarce resource.Documentation Index

Economics
Some Simple Economics of AGI
Catalini, Hui & Wu (MIT / WashU / UCLA, 2026). The verification-bottleneck thesis: as AI commoditizes execution, the verifiable share of economic activity becomes the primary driver of value. This is the macroeconomic foundation for proof-based authorization.
Accounting theory
Sorter — Events theory of accounting
The argument that the basic data of accounting should be events, not pre-aggregated balances. The intellectual root of event-sourced finance.
Ijiri — Triple-entry bookkeeping
Extending double-entry with a third dimension. CAST gives this a bilateral, cryptographically bound form.
Distributed systems & cryptography
Event sourcing
The pattern of treating an append-only log as the system of record, with all other state derived by projection.
Deterministic state machines
The basis for the guarantee that the same events produce identical outputs for all parties.
WebAuthn / passkeys
Hardware-backed identity binding — the mechanism that makes a confirmation non-repudiable.
Canonicalization & content hashing
Reproducible byte representations, so a signature made in 2026 still verifies in 2031.
This list is a starting frame, not the full bibliography. As Perspectives essays cite new sources, add them here so the reading list stays the canonical index of what CAST builds on.
