rust-libp2p VS ChainBridge

Substrate and Lighthouse use libp2p as a networking stack for communication between nodes. The libp2p framework is a versatile modular peer-to-peer networking stack. It provides a collections of abstractions, mechanisms, and protocols for facilitating communication in P2P systems. In particular, libp2p supports multiple transport mechanisms (TCP, QUIC, WebSocket, WebTransport, etc.), encryption schemes (TLS and Noise), and stream multiplexing. Higher-level protocols in libp2p are implemented on top of reliable, ordered, bidirectional binary streams, which are transparently encrypted and multiplexed by the framework.

It's a peer-to-peer "engine" with switchable components. Seems to run on different platforms (browsers, mobile, desktop, server).

At a glance, it looks pretty much like libp2p (https://libp2p.io/) but seems to integrate with libp2p as well (meaning you should be able to use Bifrost on one end, and libp2p on the other), so I'm guessing there is at least some fundamental difference, but I cannot spot it. Seems to use slightly different terminology compared to libp2p.

ComposeDB is a graph database created by 3BoxLabs, a company well-known in the Web3 ecosystem for their work on decentralized identifiers (DIDs) and their main product the Ceramic network. Ceramic is a network of nodes that store and share composable data streams on top of libp2p, the network stack that also powers IPFS.

Yes, there is already a Rust version (https://github.com/libp2p/rust-libp2p) that behaves well at this level but I think we can reach a higher level of performance on this point with Zig. Also, if you look at the long term roadmap of libp2p (https://github.com/libp2p/specs/blob/master/ROADMAP.md), the mobile devices and IoT integrations for example are part of the considerations.

At Filecoin Foundation, we see the technologies in the Filecoin ecosystem offering rock-steady stepping stones to this better future. Libp2p lets individual users find and talk to each other, without needing central servers. IPFS gives new services a way to find data, wherever it is stored — freeing them from dependence on one social media company over another and letting users move from one service to another. The Filecoin network itself, with incentivized storage, not only provides a provably stable basis for hosting content, but also shines a light on the kind of incentive systems that will enable independent social media to sustain and provide for itself for the long run, without relying on the largesse of the current tech giants.

So, after rolling my eyes and saying to myself 'not another web3 protocol', I began to understand the need for something new that not only takes advantage of the cutting edge in peer to peer networking but also acknowledges the fact that the client-server architecture is also not going away (which is incredibly important in a world full of low-powered, embedded devices).

ChainSafe is a leading blockchain research and development firm specializing in infrastructure solutions for the decentralized web. Alongside client implementations for Ethereum, Polkadot, Filecoin, and Mina, we’re building a portfolio of web3 products — Files, Storage, the Gaming SDK, and ChainBridge. As part of our mission to build innovative products for users and better tooling for developers, ChainSafe embodies an open source and community-oriented ethos.

Polkadot · ChainBridge. Between Polkadot and Ethereum.

The most mature bridge that I'm aware of is the ChainSafe bridge. See https://github.com/ChainSafe/ChainBridge. I'd imagine it is possible to "wrap" the Handshake name on another network, but is it really all that useful? Its possible there is utility from more users on Ethereum, so you'd be more likely to find a buyer for your name. If it does turn out to be actually useful, doing it in a trustless way is probably too expensive for it to be worth it.

Tried it, it didn't work. Ethereum bridge will solve it: https://github.com/ChainSafe/ChainBridge

The first parachain (Plasm) launched on test net (Rococo). This is likely anticipation of parachain auctions on Kusama and then Polkadot. You can't wrap DOT yet but there will be interoperability between Polkadot and Ethereum via various bridges for example https://github.com/ChainSafe/ChainBridge
