With the opening of registration qualifications for the Rococo testnet parachain, Polkadot and Kusama parachain auctions have gradually begun. At that time, users can use DOT and KSM to vote for supported projects to help them participate in the auction. In anticipation of the slot auction, Polkadot (DOT) and its Canary Testnet Kusama's Token (KSM) have performed strongly in the past six months and have become one of the most dazzling protagonists in the market. As of January 14, 2021, the price of Polkadot has exceeded $12 and the market value has exceeded $10.8 billion.

Polkadot, as a cross-chain underlying project, the next-generation blockchain protocol, has gained too much aura in 2020. The development process of the Polkadot test network is smooth, and the ecological projects have risen rapidly, sounding the clarion call for a new generation of blockchain. According to the Polkaproject website, Polkadot ecological projects have reached 337, covering infrastructure, wallets, stablecoins, browsers, games, DeFi, DApp and other aspects.

So, what are the worthy values and projects in the Polkadot blockchain ecology? OKEx Intelligence Bureau selected some well-known projects for sorting and inventory. This article will focus on the following projects

1、Polkadot（DOT）

Polkadot was founded in 2015 by the former CTO of Ethereum, Gavin Wood (Lin Jiawen), and was a blockchain project developed by Parity Technology Company in November 2017. According to Gavin Wood's description in the white paper, Polkadot is a blockchain protocol designed to support "parachains created by different developers." Simply put, Polkadot is a collection of blockchains composed of heterogeneous multiple blockchains. The main purpose of Polkadot is to connect the currently independent blockchains. Through Polkadot, communication and data transfer can be carried out between different blockchains.
