Dossier
Cambridge (and the wider UK research belt including UCL in London) is where the Overledger whitepaper is archived: Verdian, Tasca, Paterson, Mondelli, 2018, UCL Discovery. Tasca’s UCL Centre for Blockchain Technologies is the academic neighbour. Luke Riley’s KCL years sit on the same island. Read the papers before the homepage.

Did you know
CBDC
Did you know tokenised sterling deposits are not a digital pound?
A CBDC is a liability of the central bank. GBTD tokens are liabilities of Barclays, HSBC, Lloyds, NatWest, Nationwide and Santander. Quant was selected to provide the programmable-money infrastructure — Overledger and PayScript — not to issue the money. The future-of-money move is making commercial-bank money programmable without pretending it is central-bank money.

Did you know HTTP 402 has been reserved since 1997?
‘Payment Required’ sat unused in the web stack for a generation. x402, hosted at the Linux Foundation, revives it so software can pay software. Quant’s published claim is that Fusion Layer 2.5 is x402-ready from day one, and that the missing piece is settling those agent payments in tokenised bank money rather than only in unregulated tokens.

Did you know Overledger is not a twelfth blockchain?
The 2018 whitepaper’s whole point is single-ledger dependency. Overledger maps a request onto Ethereum, Hyperledger Fabric, Corda, a bank core, or all of them. If the future of money is many ledgers and many rails, the scarce resource is a gateway OS, not another validator set.
