Subject: Re: [Blockchain-interop] Cactus vs ODAP


Hello Mike,

Cactus is concerned with the technological infrastructure (technical layer) that supports business logic. It implements software that can utilize blockchains (i.e., the connectors). ODAP is a protocol (running at the semantic layer) that can benefit from Cactus as an infrastructure. For more info on the layers, check Figure 3, page 8 of https://arxiv.org/pdf/2005.14282.pdf<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Farxiv.org%2Fpdf%2F2005.14282.pdf&data=04%7C01%7Cmichael.mcbride%40futurewei.com%7C29f58ce9b9fe4aac534a08d99e3f977a%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C1%7C637714818236121216%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=gYRe8gky9ydlL0J1X%2FCU59TYiR5JyBK7yPOtZMpI%2Bs4%3D&reserved=0>.

In short, ODAP can be built on top of Cactus, which in fact is being done: https://github.com/hyperledger/cactus/pull/1275<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fhyperledger%2Fcactus%2Fpull%2F1275&data=04%7C01%7Cmichael.mcbride%40futurewei.com%7C29f58ce9b9fe4aac534a08d99e3f977a%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C1%7C637714818236131303%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=0fVor1Igf5enyCFYQdSFvYY214aN4yFrncD2NK8oIFY%3D&reserved=0>

There is also a Hyperledger blog post comparing Cactus to other interoperability projects that can shed some light on Cactus' capabilities.

Cheers,

Rafael

Hello all,

Has anyone compared HL Cactus and ODAP? I'm on an IEEE call right now discussing interop and I mentioned ODAP to them. It would be helpful to have a comparison. If one doesn't exist I may give it a go.

Thanks,
mike
