Quant Network

The Quant Network company was founded in 2015 by Gilbert Verdian.^[5]^[4] During his career across government and financial services, he identified persistent challenges in connecting enterprises, systems and networks securely. Quant was created to address these issues by providing interoperability and tokenisation infrastructure for regulated financial institutions, built around its Overledger platform, an interoperability layer that connects different blockchains and legacy systems, and related products that began launching around 2018.^[3] In parallel, Verdian helped initiate the ISO Technical Committee ISO/TC 307 on blockchain and distributed ledger technologies, focusing on areas such as security, privacy and interoperability, and an ISO standard for blockchain interoperability was published in 2026 after a decade-long standards process.^[5]^[7]^[6]

From 2024, Quant has worked on programmable money and tokenised deposits, serving with R3 as a technology provider for the UK Regulated Liability Network (RLN) initiative led by UK Finance, where its Overledger platform delivers programmability and interoperability across different forms of money.^[8] In 2025, Quant was selected to create the payments infrastructure and bank technology for the UK's Tokenised Sterling Deposits (GBTD) project and launched QuantNet, a programmable infrastructure and network intended to help banks connect to tokenised money and digital assets.^[9]^[10] In 2026, Quant introduced its Fusion multi-ledger rollup network, designed to coordinate assets and transactions across multiple distributed ledgers, and joined the x402 Foundation, a Linux Foundation initiative focused on enabling payments between software and AI agents using protocols that connect internet-native payment systems with regulated banking rails.^[11]
