Overledger Fusion: A Layer 2.5 to bridge institutions with public blockchains

Just came across this from Quant Network — they’re calling it a “Layer 2.5” aimed at helping institutions use public blockchains without giving up compliance or control.

It seems like they’re combining a multi-chain rollup with trusted node access controls and native asset interoperability — no wrapped tokens or mint/burn bridges. Also interesting to see the emphasis on node jurisdiction and privacy-preserving smart contracts.

Curious how this will play out

“Layer 2.5” a helpful mental model — or just marketing for a hybrid L2/L3 stack?

Quant Network introduces Overledger Fusion, a multi-chain Layer 2.5 network aimed at enabling institutional adoption of public blockchains through compliance, privacy, and interoperability.
