IOTA Tangle
IOTA Tangle is the blockchain layer on which FenixTrace records every product, identity, and report. Based on a DAG (Directed Acyclic Graph) architecture, it offers feeless transactions, extreme scalability, and Move-based smart contracts, making supply chain traceability accessible and secure.
What is IOTA Tangle?
IOTA is a next-generation distributed ledger technology (DLT) that uses a DAG architecture called the Tangle, instead of the classic chain of blocks. This approach eliminates the need for miners and fees, enabling free and high-speed transactions. IOTA is not an EVM blockchain: it uses Move-based smart contracts, a language designed for security and formal verifiability.
Unlike blockchains such as Ethereum or Polygon, where every operation requires gas fee payment, on IOTA every transaction is free. This makes it possible to register thousands of products without additional costs, a crucial advantage for high-volume supply chains.
The Tangle is designed for the Internet of Things (IoT) and industrial applications, with low latency, high throughput, and a minimal energy footprint. FenixTrace leverages these features to offer a sustainable and scalable traceability platform.
Why IOTA for Supply Chain?
Feeless Transactions
Transactions on IOTA require no gas fees, making product registration economically sustainable for any volume of supply chain operations.
Extreme Scalability
The Tangle supports thousands of transactions per second with fast finality, ideal for global supply chains requiring real-time tracking.
Energy Efficient
IOTA uses a low-energy consensus mechanism, aligned with the sustainability goals of FenixTrace and green businesses.
Move-Based Smart Contracts
IOTA supports Move-based smart contracts, a safe and verifiable language that minimizes vulnerability risks in on-chain code.
How FenixTrace Uses the Tangle
Every critical action on FenixTrace generates an on-chain transaction. Here are the main transaction types recorded on the Tangle:
add_product
Registration of a new product in the supply chain with all metadata (name, batch, origin, certifications). Creates the primary on-chain record.
DID Registration
Creation of the decentralized identity (DID) for a company. Associates a wallet address with a verifiable identity following the W3C standard.
DID Notarization
Second wallet signature that notarizes and certifies the DID identity. Cryptographic proof of the registered identity's authenticity.
Red Flag
Irregularity report on a product by an authorized Red Flagger. Includes reason, IPFS evidence, and immutable timestamp.
IOTA Explorer Integration
Every transaction recorded on FenixTrace is publicly verifiable via the IOTA Explorer. The public scanner includes direct links to the explorer for every product, DID identity, and red flag, allowing anyone to independently verify the authenticity and integrity of data.
The explorer shows all transaction details: hash, timestamp, sender, recipient, and payload. This creates a total transparency system where no data can be hidden or manipulated.

Traceability remains available beyond the commercial lifecycle of each product.
Frequently Asked Questions
Yes, transactions on IOTA require no gas fees. Unlike Ethereum or other EVM blockchains, the Tangle does not require fee payments to register data. This makes FenixTrace economically accessible for businesses of any size, even with high volumes of products to track.
No, once a transaction is confirmed on the Tangle, the data is immutable. No one, not even FenixTrace administrators, can alter or delete an on-chain record. This is the fundamental guarantee of system transparency and integrity.
IOTA is a decentralized network with globally distributed nodes. Even if some nodes go offline, the network continues to function. Already registered data is replicated across all nodes and cannot be lost. FenixTrace also maintains a local cache to ensure operational continuity during any temporary interruptions.
IOTA has a unique architecture based on DAG (Directed Acyclic Graph), not traditional blockchain. It is not EVM-compatible, but uses Move-based smart contracts that offer greater security. For FenixTrace, this means faster transactions, with no costs, and a smart contract language designed to minimize vulnerabilities.
