Polkadot test network Rococo V1 opened the parachain test qualification registration on the 11th of this month. Currently, Laminar Protocol, Acala Network, Darwinia, Plasm and Robonomics have become the first projects to participate in the construction of parachains. Among them, Plasm has deployed the first parachain in Rococo V1.
1. Laminar Protocol ( synthetic asset and margin trading platform )
In the Polkadot DeFi ecosystem, Laminar belongs to the protocol layer and supports synthetic assets and margin trading. Through the Laminar platform, users can use stablecoins to exchange various anchored foreign exchange assets, and use the assets for margin trading (up to 50 times), or deposit interest through the money market.
To put it simply, the current foreign exchange transaction process is full of issues such as pricing opacity and price manipulation. Laminar hopes to build an open and transparent foreign exchange trading platform through blockchain technology .
In November 2019, Laminar was funded by the Web3 Foundation, and its core team members overlapped with another Polkadot project team. It is reported that the core members of the Laminar team are Su Ruitao (Lianchuang and CEO) and Bette Chen (Lianchuang). The latter is also the Acala Network co-creation.
2. Acala Network (Decentralized Open Finance Alliance )
Like Laminar, Acala Network is also a Polkadot protocol layer project, and its main business includes three parts:
1. Stable coin generation platform;
2. Liquidity Release Agreement Homa ;
3. DEX trading platform.
The relationship between these three is mutual coordination and mutual development. Among them, the stablecoin generation platform is the core part of Acala . Users can use a variety of cross-chain asset mortgages to generate a decentralized stable currency, aUSD, which can send and receive USD between all blockchains connected to the Polkadot network.
In terms of capital support, in addition to funding from the Web3 Foundation, Acala has also received support from several first-tier venture capital institutions such as Polychain, Pantera, ParaFi, Hypersphere, DCG, Coinfund, 1confirmation, Hashkey and KR1.
3. Darw inia (cross-chain bridging network)
Darwinia is a cross-chain bridging network developed based on Substrate. In addition to providing basic cryptocurrency cross-chain services, it also supports cross-chain game assets and non-standard assets.
Currently Darwinia has launched the first phase of the mainnet, and there are still three phases before the official launch. In the first phase, Darwinia only provides the staking function, and the second to fourth phases will provide: one-way, two-way, and multi-directional cross-chain services.
In addition to cross-chain business, Darwinia also develops the blockchain game "Evolution Planet", and its network native token RING is also the circulating token in the game. Users can obtain KTON, another token of Darwinia network, by locking RING.
As of now, RING is quoted at US$0.0047, an increase of 8% in 24 hours; KTON is quoted at US$65.33, a decrease of 3.4% in 24 hours.
Darwinia is funded by the Web3 Foundation and the Digital Renaissance Foundation.
4. Plasm (Layer 2 solution of smart contract chain / Polkadot)
Plasm is a scalable smart contract chain based on Polkadot. It is developed using Substrate and is a project for the Polkadot community in Japan. Its funders include Longhash Ventures and Stake Technologies.
In Polkadot, Plasm mainly solves Layer 2 issues, namely scalability and interoperability issues. Officially, Plasm can provide higher TPS, lower transaction costs, and faster block determination, and realize the connection between Plasm Network and Polkadot, and provide interoperability between blockchains.
The Plasm mainnet has been launched, and its native token PLM (non-ERC-20) has been issued through two lock-up airdrops and an additional 22.708 billion PLM (for teams and communities). At present, the total amount of PLM is undecided, and the team plans to confirm it after the third lock-up airdrop ends, and the tokens cannot be transferred temporarily.
5. Robonomics (based on the Substrate IoT project)
Robonomics is a Substrate-based Internet of Things project that attempts to integrate Cyber Physical Systems (CPSs) with the human economy. The network client is called AIRA (Autonomous Intelligent Robot Agent).
Simply put, Robonomics provides tools for cooperation with the Robot Economic Network. AIRA makes it possible to connect a variety of different robots to the robot debt market, directly sell data from robot sensors, and order logistics services and personalized products from fully automated companies.
The "link" between Robonomics and Polkadot is that the former plans to allocate 720,000 US dollars to lease Kusama slots for a period of two years. Since then, the project plans to transform from the Kusama parachain to the Polkadot relay chain, and expand the network to 1 million real-time connected IoT systems.
Currently, Robonomics has successively received investments from the Web3 Foundation, Cyber Fund, P2P Capital and Aira.
