CoinTiger has hosted the AMA session together with Darwinia Network，which is a decentralized heterogeneous cross-chain bridge protocol built on Substrate, serves as critical infrastructure for interoperability across the blockchain networks.

Session1: QA with the Project representative

Q1. First simple question — who are you?

Bree: Hi everyone！This is Bree and I’m the CMO of DARWINIA.

Q2. What is Darwinia?

Bree: Darwinia has been building a permissionless non-custodial bridge protocol, featuring efficiency, low cost, decentralization of cross-chain tokens and NFTs transfer, as well as other cross-chain operations. Darwinia bridge solution integrates technologies, including super-light client, zero-knowledge, and optimistic verification mechanisms. Darwinia bridge distinguishes it from other bridges in terms of quality and how decentralized the bridge is, which could carry high-value cross-chain asset transmission. Darwinia was also included in the Cointelegraph research report as a critical cross-chain infrastructure

Q3.What role does Darwinia play in the Polkadot ecosystem?

Bree: For our role: I would say, Darwinia connects Polkadot and other public chains. As the “Golden Gate Bridge’’ for the cross-chain networks, Darwinia provides the safest heterogeneous cross-chain solution without middlemen, making the cross-chain asset transfer safer, cheaper and more frictionless.

Darwinia also bridges other polkadot ecosystem parachains cross-chain interoperability to achieve more broad asset circulation. They are also able to focus more on their business applications but not building repeated direct bridges on their own. Darwinia serves as the bridge center in the polkadot ecosystem. https://twitter.com/darwinianetwork/status/1354023147364904960?s=21

Like, say a lot of defi projects in the Polkadot ecosystem have deployed our bridge. Our Ethereum and Darwinia Bridge will launch today～

Q4. Investors are very excited about Polkadot’s projects this year, so what makes Darwinia different from other Polkadot projects?

Bree: On every blockchain, Bitcoin, and Ethereum, a trustless feature has been inherent to the transaction.
But when it comes to cross-chain, everything seems to go back to the start point. There are many bridges out there. But mostly are custodial bridges relying on middlemen. But Darwinia bridge has solved cross-chain challenges，removing the trust needed and middlemen multi-sig. Less Trust, More Truth. Our tech innovation upgraded the classic chain relay solution. Classic chain relay requires relaying each and every block, which is not economically feasible.
Darwinia ChainRelay is a super light client, it integrates cryptography technology MMR to make sure each confirmed block header aware of the history chain state. It also implements an internal optimistic verification game process to identify the longest chain. It supports relay on demand which is triggered by a cross-chain transfer requester. It’s economically feasible and completely trustless. With such an efficient chain relay, we are able to build two-way decentralized bridges across completed blockchains. Except all these above, another exciting advantage of Darwinia bridge chain is supporting the cross-chain transfer of NFTs as well.

Q5. What are the main advantages of holding RING?

Bree: Users, relayers, nominators, validators, council members and applications will need the RING for
(i) the operation of the network,
(ii) lock-up in exchange for commitment token KTON,
(iii) staking to obtain influence power and participate in the governance of the network,
(iv) paying for cross-chain transfer service fees

And actors can use KTON for
(i) being identified to have long-term interest aligned with the project,
(ii) staking to obtain influence power and participate in the governance of the network,
(iii) registering and activating tokens at the ChainRelay by (the token project owner) so that users can transfer these tokens

Evolution Land is
(i) accepting RING for users to auction in-game props (NFT) such as lands, apostles, etc
(ii) accepting KTON for users to auction high-rank in-game props (NFT),
(iii) paying KTON holders with dividends from game revenues,
(iv) allowing KTON holders to participate in governance, such as voting for continent tax rate etc.

Evolution land is our cross-chain game

Users need to pay RING to interact with other dApps deployed on Darwinia Network. We encourage dApps to recognize KTON holder demographics and give them proper privileges.

Session 2: Open Questions by the Community

Q1. A lot of projects are working on Ethereum cross-chain bridge, what distinguishes Darwinia as the Golden Gate Bridge in the cross-chain ecosystem?

please refer to my answer in the first session～

Q2. Does Darwinia have smart contract capability with zero-knowledge proof? what type of language do you expect to support?

We have launched our smart contract solution Darwinia virtual machine.

please refer to this article for our smart contract solution～

Q3. Almost every investor is interested in large Defi projects as it delivers high returns and is fast. For what reasons can convince small and large investors to trust and invest in your project?

Darwinia was included in the Cointelegraph research as critical infrastructure for the whole crypto world
Darwinia was also included in the polkadot light paper，star project
Darwinia also won parity badge for its outstanding tech innovations.
Darwinia has been engaged with the global community，different events to give away rewards to users！

Q4. What are your plans for global expansion, on building and developing or getting customers and users, or partnerships?

We have been working with defi，nft，game，all kinds of projects to improve our global influence.

Q5. Which area are you focusing on at the moment? (DeFi, Stake,Dapps..) and what are your goals for this year ? In how many ways or what are the ways, your project generates revenue? What is the revenue model? How it can be beneficial for both investors and for the project itself?

Also will focus on the polkadot and Kusama parachain auction this year.
