The BeeCoin multi-chain architecture
The BeeCoin ecosystem is built around a family of specialized blockchains, named Bc0 to Bc9. Each chain has a specific role: identity, tokenized finance, access rights, calculation traceability, communication, resources, and universal documentation.
This architecture is designed to separate functions clearly, improve traceability, and make each blockchain easier to govern, evolve, and audit.
Each BeeCoin blockchain operates under the Lesser Open Bee License 1.3, with a balance between public components and private components depending on the intended use and legal context.
Why Bc0 to Bc9?
Instead of placing every function on a single blockchain, BeeCoin distributes uses across several dedicated ledgers. This approach makes it possible to:
- assign a clear purpose to each chain,
- separate identity, finance, access, communication, and data functions,
- improve legal and operational readability,
- organize token logic by business purpose,
- create a more modular ecosystem for future services and contracts.
The result is a structured framework where each BeeCoin chain can support a precise type of asset, right, record, or interaction.
Overview of the BeeCoin chains
Bc0 — Identity
Bc0 is the identity and traceability blockchain.
It is used to identify, validate, and trace actors within the BeeCoin ecosystem. It can support a generic identity tag model and the reservation or acquisition of names or digital identifiers.
Main purpose: identity, validation, naming, traceability of actors.
Bc1 — Shares
Bc1 is the blockchain for financial shares.
It represents a share or fraction of share in Technoplane SAS à capital variable. Bc1 is intended to structure ownership representation in a tokenized and traceable form.
Main purpose: tokenized equity and shareholding structure.
Bc2 — Smart Contract
Bc2 is the blockchain for tokenized contractual rights.
It represents a financial title tokenized through a shareholders’ agreement or a conditional right that may lead, under defined conditions, to the equivalent of 2 Bc1.
Main purpose: tokenized agreements, conditional rights, conversion logic.
Bc3 — Remunerated Shareholder Account
Bc3 is dedicated to remunerated shareholder current accounts.
It supports the traceability of partner current accounts and associated remuneration mechanisms.
Main purpose: partner account financing, debt traceability, remunerated balances.
Bc4 — Valued Contribution
Bc4 tracks valued non-cash contributions.
It is designed for contributions that are not monetary in nature but can be recognized, traced, and transformed into a valuable tokenized contribution.
Main purpose: valuation of non-monetary contributions, contribution traceability.
Bc5 — Access Token
Bc5 is the access and reservation blockchain.
It is intended for the reservation of 4D airspace and terrestrial space, including parking, flight plans, and other tokenized access rights.
Main purpose: access rights, reservation, mobility slots, space usage.
Bc6 — Calculation Ledger
Bc6 is the blockchain for calculation traceability.
It records computations, results, batches, and related calculation events in a verifiable ledger.
Main purpose: traceability of calculations, processing, and certified outputs.
Bc7 — Communication Ledger
Bc7 is dedicated to communication traceability.
It records messages, interactions, and exchanges between actors, creating an auditable communication layer.
Main purpose: communication logs, messaging integrity, traceable exchanges.
Bc8 — Resource Ledger
Bc8 tracks the use of resources.
It can be used to trace the consumption of computing power and other technical resources used across the ecosystem.
Main purpose: resource usage, allocation, computing power traceability.
Bc9 — Universal Ledger
Bc9 is the universal blockchain of the BeeCoin ecosystem.
It is intended for any type of document, record, or general traceability requirement, with an open-source orientation.
Main purpose: universal documentation, general-purpose traceability, certified records.
A modular ecosystem
The BeeCoin model is not limited to a single token or a single ledger. It proposes a functional blockchain architecture in which each chain supports a category of rights, assets, or operations.
This separation can help:
- reduce ambiguity between legal, technical, and operational roles,
- support specialized smart-contract logic,
- improve governance and traceability,
- prepare future interoperability between chains.
In practice, identity can be managed on Bc0, ownership on Bc1, conditional finance on Bc2, access rights on Bc5, calculations on Bc6, communications on Bc7, resources on Bc8, and documents on Bc9.
Examples of use cases
Identity and actor validation
A participant, contributor, partner, or operator can be registered and identified through Bc0, creating a traceable digital identity layer.
Tokenized ownership
A share or fraction of share can be represented through Bc1, making ownership records easier to track and structure.
Conditional contractual rights
A tokenized contractual arrangement can be represented on Bc2, especially when conversion conditions or legal agreements must be embedded into the asset logic.
Contributions beyond cash
A technical, intellectual, or operational contribution can be recognized through Bc4, allowing non-cash value to be documented and integrated into the ecosystem.
Access and reservation
A right to reserve an air slot, a terrestrial slot, a parking location, or a time-based operational space can be managed through Bc5.
Auditability of calculations and communications
Results, batches, messages, and exchanges can be independently traced through Bc6 and Bc7.
Resource and document governance
Infrastructure usage can be logged on Bc8, while certified documents and general records can be anchored on Bc9.
The contract framework behind the chains
The BeeCoin ecosystem also introduces a contract family ranging from BcA to BcZ, covering functions such as acquisition, buyback, conversion, donation, escrow, forward contracts, guarantees, hedging, investment agreements, joint ventures, licensing, voting rights, exchange, yield sharing, and zero-coupon structures.
This means that each blockchain from Bc0 to Bc9 is not only a ledger, but also a potential base layer for multiple forms of contractual logic.
Positioning compared with mainstream blockchains
Mainstream blockchains such as Ethereum, BNB Chain, or Cardano are designed as broad execution environments for smart contracts and decentralized applications. BeeCoin takes a different path: it organizes blockchain functions by specialized domain rather than concentrating everything in a single generalized chain.
Where Ethereum focuses on a global smart-contract platform, BeeCoin proposes a set of purpose-oriented chains that can distinguish identity, financial shares, access rights, communication, resources, and universal records.
This functional separation may be especially relevant for ecosystems requiring legal clarity, operational traceability, and contract specialization.
BeeCoin vision
Bc0 to Bc9 form the foundation of a broader BeeCoin vision: a blockchain ecosystem where identity, value, access, contracts, resources, and documentation are handled through specialized ledgers designed to interact as part of a coherent whole.
Rather than a single blockchain for everything, BeeCoin proposes a structured network of blockchains, each with a clear purpose and a role in the wider architecture.
Suggested short version for hero section
Bc0 to Bc9 is the multi-chain backbone of the BeeCoin ecosystem.
Each blockchain is designed for a specific purpose — identity, shares, tokenized contracts, access rights, calculations, communications, resources, and universal traceability — creating a modular and auditable architecture for next-generation blockchain applications.
