Devvio (the company behind the DevvX blockchain and the DevvE token) has filed several patents covering core elements of its technology. Many blockchain platforms use existing public‑domain protocols (e.g., Ethereum’s smart contracts), but DevvX’s team pursued patent protection for features they believed improved scalability, privacy and regulatory compliance. The patents are publicly available, but they are written in technical legal language. This article summarises the key ideas in simple terms and highlights how each patent underpins DevvE’s DevvISE liquidity system and other unique features.
1. WO2019/067798 – Scalable Distributed Ledger System
Core idea: Rather than running a single monolithic blockchain, the patent proposes a tiered system of distributed ledgers. A T1 ledger (sometimes referred to as the “root chain”) coordinates multiple T2 ledgers, each of which has its own set of wallets and transactions. Transactions that occur between wallets on the same T2 ledger are recorded locally. When a transaction involves wallets on different T2 ledgers, it is recorded on both relevant T2 ledgers and on the T1 ledger patents.google.com. The method improves scalability because most transactions stay on their local ledger while the T1 ledger synchronises cross‑ledger transfers.
Why this matters: Traditional blockchains like Bitcoin record every transaction on one chain, which can lead to congestion and high fees. The DevvX design allows multiple sub‑ledgers (T2 chains) to process transactions in parallel and only uses the root chain (T1) for cross‑ledger transfers patents.google.com. The patent also describes optimisations such as grouping transactions, omitting redundant information and geographically placing T1 nodes close together to reduce latency patents.google.com.
Exclusive capability for DevvX: The tiered ledger system enables high throughput with near‑instant finality and forms the backbone for DevvE’s “contingent transaction sets” (multiple dependent transfers that execute atomically). When users pay with one asset and the merchant wants another asset, DevvX bundles the conversion steps into a contingent transaction set. In DevvISE, a user’s Bitcoin can be sent to a liquidity cache containing Bitcoin and DevvE; DevvE is released and sent to a cache containing DevvE and a USD stablecoin, which releases USD to the merchant. All steps occur simultaneously devve.io, leveraging the ability of the T1 ledger to coordinate multiple T2 ledgers without using slow and risky smart contracts. This multi‑ledger design is unique to DevvX and is covered by the 2019 patent.
2. WO2019/067800 – Transaction Privacy in Public Distributed Ledger Systems
Core idea: Public blockchains are transparent – anyone can see sender, recipient and amount. Devvio’s patent introduces a method for privacy‑preserving but traceable transactions. A third party receives a transaction request from the originator and splits it into several secondary transactions that are recorded on the public ledger patents.google.com. Each secondary transaction uses different wallets and may be spaced out over time. Collectively, these secondary transactions implement the original transfer, but no single on‑chain transaction reveals the entire transaction path patents.google.com. The third party stores information about the originator off‑chain (e.g., identity and wallet keys) so that regulators can trace the transaction if necessary patents.google.com.
Why this matters: Cryptocurrency users value privacy, yet regulators require traceability for compliance with anti‑money‑laundering (AML) and sanctions laws. The patent offers a middle ground: transfers are obscured from the general public, but authorised parties can reconstruct them using off‑chain records patents.google.com. Additional techniques include randomising the number of secondary transactions and spreading them over time patents.google.com.
Exclusive capability for DevvX: DevvX can offer private payments without relying on mixer services or zero‑knowledge proofs. The platform’s contingent transaction sets and DevvISE payment mechanisms can utilise this method to break large payments into smaller, time‑separated transactions while still ensuring immediate settlement from the user perspective. Because the method is patented, Devvio controls the ability to integrate such privacy‑preserving transfers into regulated exchanges and payment systems.
3. WO2022/125819 – Embedded Device Authentication System
Core idea: This patent targets the Internet‑of‑Things (IoT). It describes a way to cryptographically identify and authenticate embedded devices using a distributed ledger. Each device contains a manufacturer root key and a globally unique identifier. During registration, the device signs a transaction with its manufacturer key and sends it to the ledger. The ledger generates a registration root key and returns it. The device combines the manufacturer and registration keys to derive a child key used for future authentications patents.google.com. After registration, the device can sign messages to prove its identity without interactive communication patents.google.com.
Why this matters: Many IoT devices (sensors, payment cards, access badges) lack robust identity management. Using the blockchain to register and authenticate devices creates a tamper‑resistant audit trail and eliminates central authorities. The patent emphasises using secure processors or co‑processors on devices and deriving derivative keys to protect against key theft patents.google.com.
Exclusive capability for DevvX: DevvX can provide hardware‑level identity and authentication for devices connected to its ecosystem – for example, verifying that a payment card or IoT sensor is genuine before authorising a transaction. This is important for regulated exchanges and tokenised real‑world assets, where physical devices (POS terminals, supply‑chain sensors) need trusted identities. By owning this patent, DevvE can integrate device authentication directly into the consensus layer rather than relying on external certificate authorities.
4. WO2022/125823 – Identity on a Network
Core idea: The patent addresses self‑sovereign identity on a blockchain. Instead of storing personal data in central databases, identity information is broken into identity components (e.g., name, age, biometric data, social‑security numbers, passport scans). Each component can be tokenised and stored in the user’s blockchain wallet patents.google.com. Third‑party identity verifiers (e.g., government offices, businesses) can issue tokens attesting to particular components, and those tokens can later be referenced in identity inquiries patents.google.com. Users approve inquiries and control how their identity tokens are shared. Identity verifiers can be permissioned and revoked to prevent fraudulent attestations patents.google.com.
Why this matters: There is growing demand for digital identity solutions that balance user privacy with regulatory requirements. Current ID systems often centralise data and are vulnerable to breaches or misuse. Devvio’s identity framework allows users to accumulate verified identity attributes over time and selectively disclose them without revealing other personal data patents.google.com. Stored on a blockchain, these tokens are tamper‑evident and under the user’s control.
Exclusive capability for DevvX: The identity system complements DevvX’s payment and liquidity solutions. For example:
KYC/AML integration: users can prove their identity to comply with regulations by presenting specific identity tokens without exposing unrelated data.
Access control: IoT devices authenticated under the device‑authentication patent can check a user’s identity tokens before granting access.
Recovery and fraud prevention: identity verifiers can assist with key recovery or revoke fraudulent identity tokens patents.google.com.
This patented approach positions DevvX as a compliant but privacy‑preserving identity provider, which is critical for institutional adoption.
How the Patents Support DevvISE and DevvX
The DevvISE liquidity system, announced in March 2025, builds on the above patents to create a regulated, highly efficient digital‑asset exchange and payment network:
Liquidity Caches and contingent transaction sets: DevvISE uses Liquidity Caches (LCs) containing primary digital assets (e.g., BTC, ETH) and shared digital assets (DevvE and Fias) devve.io. When a user wishes to convert one asset to another or make a payment, DevvX bundles multiple transfers into a contingent transaction set that executes atomically devve.io. Because cross‑cache transactions might involve different T2 ledgers, the tiered ledger patent (WO2019/067798) allows these sets to be recorded efficiently on the T1 ledger without smart contracts.
Instant conversions and lending without smart contracts: DevvISE’s lending system defines loans on‑chain at the consensus level rather than using smart contracts, allowing lenders to retain collateral in their own wallets devve.io. This reduces counter‑party risk and tax complications. The privacy patent (WO2019/067800) underpins optional private transaction bundles, while the identity and device patents support KYC‑compliant asset transfers.
Regulatory compliance and security: Liquidity Caches offer private‑key loss protection, theft protection and bailment solutions devve.io. By combining identity tokens and device authentication, DevvX can ensure that only authorised individuals and devices interact with the exchange.
User‑controlled assets: DevvISE is non‑custodial; users retain control of their assets, and transactions settle instantly devve.io. The tiered ledger design ensures high throughput, while privacy features balance confidentiality with traceability.

Conclusion
Devvio’s patents reveal a coherent strategy: build a scalable, multi‑layer ledger, add privacy‑preserving transaction mechanisms, provide hardware and identity authentication, and integrate these into a regulated liquidity infrastructure. The DevvISE system leverages these patents to offer features such as instant asset swaps, on‑chain lending without smart contracts, and contingent transaction sets that settle atomically. Because DevvE holds the patents, competitors cannot legally replicate these specific methods without licensing them. For users and potential investors, understanding these patents clarifies why DevvX markets itself as “crypto without chaos”—a platform that combines the efficiency and innovation of DeFi with the protections and compliance required by institutional finance.
