Cross-app character portability through wallet-based ownership checks
Wallet-Scoped Character Libraries for Realbits Apps
A paper-style architecture analysis of wallet-scoped character portability in Realbits, focusing on ERC-721 ownership reads, signature-bound sessions, metadata binding, cache invalidation, and mobile wallet integration.
Prisma-backed creator studio data models for provider-managed character inventory
Prisma-backed creator studio data models for provider-managed character inventory
A technical, paper-style analysis of modeling creator characters as an auditable provider inventory in Prisma/PostgreSQL for Realbits.
VRM avatar rendering and Filament-backed mobile character presentation
VRM on Flutter Mobile: Deterministic Semantics and Filament-Backed Rendering in Realbits
A technical architecture analysis of Realbits' mobile avatar pipeline that treats VRM as a portable presentation format and separates semantic avatar logic from Filament-backed rendering concerns.
ERC-721 character ownership and creator royalty escrow for AI assets
ERC-721 ownership and enforced creator split rails for Realbits AI characters on Polygon
A technical, architecture-first analysis of how Realbits can implement character ownership and creator compensation using ERC-721 entitlement plus an explicit royalty split escrow path that avoids relying on optional marketplace royalty signaling.
Next.js provider surfaces, API routes, and scheduled maintenance jobs
Control-plane design for provider maintenance in Realbits: Route Handlers, scheduled jobs, and idempotent repair cycles
A technical paper-style analysis of how Realbits can treat Next.js route handlers and Vercel cron jobs as a provider-side control plane for character lifecycle and reward distribution workflows.
Local voice model packs for speech recognition and text-to-speech in mobile chat
Manifest-First Voice Packs for Local Mobile Chat
A technical analysis of how Realbits should treat local STT and TTS as versioned voice pack contracts for mobile chat, with emphasis on manifests, runtime boundaries, and release evidence.
Reusable character-card schemas and persona-evaluation gates
Schema-Observable Personas: Character Cards as Regression Fixtures for Local Chat
A technical analysis of reusable character-card schemas and persona-evaluation gates in Realbits, focusing on schema observability, local Gemma prompt binding, and release-grade regression evidence.
On-device Gemma and LiteRT language-model packaging for Flutter chat apps
Model-Pack Contracts for Local Gemma in Flutter Chat Apps
A technical analysis of how Realbits should treat on-device Gemma as a versioned model-pack contract for Flutter chat apps, with LiteRT-LM as the native runtime boundary and provider manifests as the cross-app control surface.
Cross-app character portability through wallet-based ownership checks
Wallet Ownership as a Revocable Entitlement Plane for Realbits Characters
A technical analysis of cross-app character portability in Realbits as a revocable entitlement system built from wallet authentication, ERC-721 ownership reads, metadata validation, and provider-side indexing.
Prisma-backed creator studio data models for provider-managed character inventory
Prisma-backed creator studio inventory as a provider control-plane contract
A technical architecture article analyzing how Realbits should model creator-managed character inventory in PostgreSQL using Prisma so publish, versioning, and ownership workflows remain auditable and cross-app reusable.
VRM avatar rendering and Filament-backed mobile character presentation
Portable Avatar Semantics for Flutter Mobile: VRM 1.0 + Filament as a Shared Presentation Runtime
A technical article that evaluates how Realbits should map VRM avatar semantics to Filament-backed Flutter mobile rendering, with emphasis on portability, runtime determinism, and provider-level reuse.
ERC-721 character ownership and creator royalty escrow for AI assets
ERC-721 Character Ownership and Creator-Royalty Escrow for AI Character Assets
A technical analysis of how Realbits can model characters as ERC-721 provider assets and route creator payouts through a dedicated royalty escrow without putting prompts or model binaries on chain.
Next.js provider surfaces, API routes, and scheduled maintenance jobs
Next.js as a Provider Control Plane: Route Handlers, Cron Jobs, and Repair Loops in Realbits
A technical analysis of how Realbits can use Next.js Route Handlers and scheduled cron workers as a provider control plane, with emphasis on idempotency, cache invalidation, and maintenance-loop design.
Local voice model packs for speech recognition and text-to-speech in mobile chat
Local Voice Model Packs for Speech Recognition and Text-to-Speech in Mobile Chat
A technical analysis of how Realbits can package local STT and TTS runtimes as portable model packs for mobile chat while balancing latency, bundle size, and cross-platform runtime differences.
Reusable character-card schemas and persona-evaluation gates
Character Cards as Testable Runtime Inputs
A technical analysis of reusable character-card schemas and persona-evaluation gates for Realbits' Gemma-backed chat surfaces.
On-device Gemma and LiteRT language-model packaging for Flutter chat apps
Packaging On-Device Gemma for Flutter Chat Apps: A LiteRT-LM and Web Inference Architecture Analysis
A technical comparison of Realbits' two Gemma runtime tracks for Flutter chat: local ONNX/Transformers.js in web and native LiteRT-LM packaging on mobile and desktop, with deployment, compatibility, and maintainer burden tradeoffs.
Cross-app character portability through wallet-based ownership checks
Cross-App Character Portability Through Wallet-Based Ownership Checks
Technical analysis of how Realbits can use wallet-authenticated NFT ownership checks to unlock reusable character assets across all Realbits apps without rebuilding per-app entitlement logic.
Prisma-backed creator studio data models for provider-managed character inventory
Prisma as the Inventory Contract for Provider-Managed Characters
A technical analysis of how Realbits can use Prisma and PostgreSQL to model creator-studio inventory, provenance, and publish flows for provider-managed character assets.
VRM avatar rendering and Filament-backed mobile character presentation
Filament-Backed VRM Avatars for Mobile Character Presentation
A technical analysis of how Realbits can treat VRM avatars as portable presentation assets while keeping Filament, Flutter, and runtime semantics separated enough for mobile parity and future provider reuse.
ERC-721 character ownership and creator royalty escrow for AI assets
ERC-721 Characters as Provider Assets, Not Prompt Containers
A technical analysis of how Realbits can use ERC-721 ownership and royalty escrow contracts for AI character assets while keeping runtime prompts and provider manifests off-chain.
Next.js provider surfaces, API routes, and scheduled maintenance jobs
Provider Workloads at the Route Boundary
A technical analysis of how Realbits can use Next.js Route Handlers and Vercel Cron Jobs as provider-facing maintenance surfaces without losing idempotency, observability, or operational clarity.
