In this article, I explored 3 key players and their main products in Web3 ecosystem, opinionated from tech perspective. They are:
Parity
ProtocolLabs
ConsenSys
The official website defines Parity as :
Blockchain Infrastructure for the Decentralised Web From the Substrate blockchain framework to Polkadot, the sharded protocol enabling blockchains to operate seamlessly together at scale, Parity builds the foundation of Web 3.0.
Parity is more like a Web3 tech solution provider than a market player. The company has created 2 key solutions as Polkadot and Substrate. Furthermore, the founder is Gavin Wood, Etherum’s founder.
Polkadot unites and secures a growing ecosystem of specialized blockchains called parachains. Apps and services on Polkadot can securely communicate across chains, forming the basis for a truly interoperable decentralized web.
The core idea of Polkadot is like XMPP messaging protocol, which any service provider and build a messaging product upon the protocol, and messing products from different providers and communicate with each other. In the old times, Google Chat can talk to Microsoft MSN Messenger! Another example would be email protocols like POP/SMTP/IMAP. Providers like Microsoft / Cisco / Apache etc can have different implementations for different platforms (both client and server side). All protocol compliant implementation can talk to each other.
Then came Web2.0 players like Facebook and Google, or more like Alibaba / Tencent, who provide non-inter-connected service and disconnect the internet, make internet many disjoint islands.
Polkadot tries to inter-connect different blockchain implementations, which may have different focus, to talk to each other, make cross-chain easier, or in so-called “parachains“.
The core tech stack features WebAssembly and Rust. It shares many designs with Substrate.
Source Code:
https://github.com/paritytech/polkadot
the only flexible, open, interoperable, and future-proof blockchain framework.
Substrate provides blockchain code framework to quickly setup a new customized blockchain. The core tech stack features libp2p, WebAssembly and Rust.
Substrate provides a wasm runtime (source code).
Substrate also provides source code for Android / iOS / Browser based lite client called Parity Signer to connect to blockchain instead of heavy node, thus make it easier to launch your own blockchain for massive end-users.

Two main products provided by ProtocolLabs are IPFS and FileCoin.
IPFS makes the web work peer-to-peer. IPFS is a protocol for storing, addressing, and transferring data, designed to replace HTTP in many contexts. IPFS uses content-addressing to uniquely identify and link to information. IPFS is one of the leading protocols of Web3, crypto, and the decentralized web movements. IPFS serves millions of end users and tens of thousands of developers. It powers the websites and applications of small startups, large enterprises, and even blockchains. Filecoin is a decentralized storage network, designed to store humanity's most important information.
Filecoin is a cryptocurrency incentivized decentralized market, where storage providers earn filecoin tokens for renting out storage space. (Think airbnb for cloud storage). Filecoin is one of the leading projects in the cryptocurrency/blockchain space.
ProtocolLabs create a important library, namely, libp2p, as core component of IPFS. libp2p also serves important role in Parity’s tech stack.
libp2p has implementations in many languages, Go and Rust implementations as two of the most influent ones.
ProtocolLabs’ tech stack features Go and Rust.
One more thing, this blog post host mirror.xyz is built upon IPFS.

Web1.0 is an open internet inter-connected by many W3C protocols like HTTP / IMAP / XMPP.
However, in Web2.0, information is provided by mobile apps rather than open-standard browsers, internet is more like serveral disjoint islands, i.e. Google, Amazon, Facebook, Alibaba, Wechat, etc, and many little orphan island reefs.
In Web3.0, we start over, and we may construct a open and inter-connect internet again.
This post is highly opinionated. Other tech players not covered include:
