Architecture

b14g Architecture - The Coordination Layer for Bitcoin Yield and Security

1. Architecture Overview

b14g is a modular BTCFi coordination layer connecting Bitcoin’s liquidity with multi-chain dual-staking ecosystems.

It unifies three core components — Self-Custodial BTC Staking, BTCFi Vaults, and the Merge Marketplace — into a composable infrastructure that can be integrated by any Bitcoin-aligned chain.

Architecture Pillars

Layer	Core Component	Purpose
Distribution Layer	BTC Self-Custodial Staking + Vaults	Activate Bitcoin yield and user participation
Middleware Layer	Merge Marketplace + Dual-Staking SDK	Match liquidity, route yield, and enable chain integrations
Base Layer	Unified BTCFi Layer + $B14G	Coordinate governance, incentives, and cross-chain data

2. BTC Self-Custodial Staking

Bitcoin security, without custodial risk.

• Built on Bitcoin time-locked staking, allowing users to lock BTC directly from their wallet (e.g., via Taproot scripts).

• BTC remains on the Bitcoin mainnet; proof-of-stake delegation is managed through cross-chain attestation.

• Enables non-custodial staking to secure Bitcoin-aligned chains (Core, Babylon, Stacks, etc.).

• Provides the foundation for BTCFi vault yield flows.

Key Features:

• Time-locked BTC staking

• Verifiable on-chain yield accrual

3. BTCFi Vaults

Yield infrastructure for dual-staking and DeFi strategies.

• Smart-contract-based vaults that combine BTC and partner tokens (e.g., CORE, BABY, STX) to earn shared rewards.

• Each vault enforces allocation logic: BTC is secured via time-locks; tokens are delegated to network validators or liquidity pools.

• Supports risk-adjusted yield strategies (e.g., safe vaults, leveraged vaults, stablecoin-backed vaults).

• Emits b14g Points as reward metrics for future cross-chain incentive distribution.

Example Vaults:

• dualCORE Vault — CORE lst for dual-staking

• coBABY Vault — BABY lst for co-staking

• dualSTX Vault — STX lst for dual-staking

Vault Architecture Stack:

• Smart Contracts (EVM-compatible, Cosmwasm)

• Yield Router (APY optimizer)

• Oracle & Validator Registry (APR data feed)

• b14g Indexer (cross-chain position tracking)

4. Merge Marketplace

Unifying BTC and token stakers into one marketplace.

• A dual-staking matching engine where BTC stakers post “orders” and token stakers match them.

• Works like an on-chain orderbook for yield: matching BTC and token capital in real time based on yield preferences, duration, and risk score.

• Supports both manual participation (for retail) and automated routing (for protocols and aggregators).

• Fully transparent and composable — other dApps can integrate marketplace liquidity via API or SDK.

Technical Modules:

• Matching Engine Smart Contracts

• Order Registry & Indexer

• Yield Router & Fee Module

• Marketplace SDK for chain partners

5. Data and Identity

Unified BTCFi Layer

• Tracks user positions, staking history, and yield data across all supported chains.

• Aggregates vault data for analytics, reputation, and institutional reporting.

• Enables “BTCFi identity”, a unified profile representing all BTC-based yield activities.

Data Sources:

• Vault smart contracts

• Cross-chain indexers (Babylon, Core, Stacks, etc.)

6. Token and Governance

$B14G Token Functions

Function	Description
Governance	Adjust marketplace fees, vault parameters, reward rates
Yield Routing	Direct yield flow and protocol incentives
Fee Capture	Collect a small percentage of performance and matching fees
Staking Boost	Enhance user yield through loyalty multipliers
Cross-Chain Incentives	Power b14g Points redemption and inter-chain campaigns

Governance Structure

• BTCFi Council (DAO): manages yield parameters and validator whitelists

• Multi-sig Treasury: collects and redistributes protocol fees

• Proposal Framework: on-chain proposals via $B14G staking

7. Dual-staking SDK

The b14g Dual-Staking SDK allows new Bitcoin-aligned chains to integrate dual-staking in days, not months.

Integration Modules:

• Validator registry interface

• Yield & reward router

• BTC self-custodial staking adapter (via Babylon light client)

• Marketplace API

Benefits for Partner Chains:

• Plug-and-play staking infrastructure

• Shared BTC liquidity pool access

• Built-in exposure to Bitcoin’s on-chain capital
