TL;DR
- Quant Network presents Fusion as neutral cross-chain infrastructure designed to unify the tokenized assets of the global financial system.
- Quant’s proposal replaces the network of bilateral bridges with a single interoperability layer where each network connects through a canonical bridge.
- Its architecture aligns with ISO TC 307 standards and follows the same neutrality principle as the BIS Agorá project.
Quant Network published a technical analysis positioning Fusion as the cross-chain infrastructure the global financial system needs to prevent tokenization from devolving into a set of disconnected networks. The document warns that banks, market infrastructures and fintechs are building their own chains and issuing their own tokens, but connecting them through a scattered network of bilateral bridges that scales poorly and accumulates risk after risk.
The underlying problem is not technical but structural. Tokenized assets are distributed across dozens of blockchains with different rules, trust models and liquidity pools. A tokenized bond on one network cannot easily be used as collateral on another. A stablecoin on a public chain cannot settle natively against a deposit on a permissioned network. Connecting ten networks bilaterally means building and securing dozens of separate connections, and each additional network multiplies that complexity.
Quant: Neutrality as a Structural Requirement
Quant’s proposal establishes that Fusion does not replace existing networks but connects them. A bank keeps its Hyperledger network. A market infrastructure maintains its current ledger. Assets remain anchored to their chain of origin while a representation of them circulates through the shared fabric. The institution connects just once and from there accesses everything the network reaches.
The Quant document explicitly states that neutrality is a structural requirement, not a differentiating feature. Networks governed by consortia or individual institutions are not flawed in their design, but their governance structure disqualifies them as shared infrastructure for the entire industry. The Bank for International Settlements reached the same conclusion in the Agorá project, where eight central banks and more than 40 private institutions are testing a shared ledger that deliberately keeps central bank money in separate jurisdictions, using a common layer only for coordination.
Necessary Conditions to Keep Moving Forward
Quant outlines four conditions that the core infrastructure must meet: neutrality, alignment with the international blockchain interoperability standard ISO TC 307, regulatory oversight that survives connection through the Fusion Firewall and the Trusted Node Program, and native asset movement through canonical bridges that preserve the trust of the originating chain, without wrapped tokens that introduce additional risk profiles.
For the securities services sector, the argument is clear-cut: tokenized funds such as BUIDL from BlackRock and BENJI from Franklin Templeton already operate on eight or more blockchains each, and every additional chain adds one more service relationship to manage.
