Darwinia Network is a network built on Polkadot and Substrate. It enables cross-chain token technology with a way of powering asset transfers. Including Tokens without development functions (). As well as decentralized exchanges, on different blockchains. It will later become a sequence of .

The network is driven by decentralized bridges and supporting technology to support the expansion of the token network. The main applications of the system are mainly focused on the gaming space and .

DAOventures has developed:

  • DKMS Distributed Key Management System, ID Itering, no-pass signature engine;
  • Subscan, a discovery tool high accuracy built on Substrate;
  • Evolution Land, a cross-blockchain game;
  • The Darwinia network is a decentralized heterogeneous bridge circuit.

In the process of using blockchain technology to create new, DAOventures has discovered several problems with the promotion and mass use of blockchain technology:

Architectural Design

Darwinia Network () is a blockchain network powered by Substrate technology. The Darwinia network is part of an ecosystem , at the same time, is not the same as , the Darwinia network focuses on the multi-token game. Blockchain games or applications can easily trade cross-chain tokens and transfer them across the Darwinia network. Example: Convertible Cryptokitties Their (Kitties) sang NFT through Darwinia chain; Player and players can simultaneously play the game Evolution Land through the Darwinia network. At the same time, thanks to the Polkadot ecosystem, Darwinia Network can connect with a wider range of games and players.

How to move your assets from one blockchain to another

Various cross-chain solutions are building bridges between different blockchain networks. Consider the 4th branch of bridging solutions.

1. Temporarily block hashes:

As long as the two parties provide the correct hash within a certain amount of time, they can complete a trustless token exchange between chains. But everyone has to be online. And is the bridge capable of transferring assets between chains? The answer is no.

2. Goalkeeper model:

So now the problem is how to transfer assets between chains, and not just exchanges? Specifically, you need to lock your assets in the source chain and then release the same amount of assets in the target chain, when you redeem your assets, the matching assets in the target chain must be burned fire, the property in the original chain must be unlocked.

To build such a two-way latch bridge, here is the most commonly implemented solution: the custodian model, consisting of a single custodian and a federated peg, is a multi-signature federation that authenticates the transaction. your cross-chain and control the locking and unlocking of your assets. But the whole process depends on intermediary delegation, i.e. centralized or semi-centralized.

3. Lightweight Client (BTC Relay):

The property's internet connection has been reached, how to become completely unreliable? And here is a lightweight client solution, a good example is Relay. It is a client application lightweight deployed on Ethereum, is a forward contract. The relay transmits the block headers to the light client and the relay contract acknowledges the data. Block headers are virtually impossible to forge, so a lightweight client can act as a trusted source of data to verify transactions. .

The problem is that the relays need to relay every block bitcoin to a lightweight client. Don't forget about wasted storage, maintenance and high gas fees. There is not enough economic incentive for repeaters to do this work. In other words, it is technically feasible, but not economically viable.

4. Collateral:

Cross-chain pioneers still don't give up. XClaim's solution improves the custodian model to a more decentralized level. Anyone with enough collateral is deposited into the smart contract Ethereum can all act as a vault Bitcoin to facilitate the cross-chain process. But it introduces an additional level of external price flow and is not friendly to NFT assets. And if you see an illustration of the intermediary here, it's not without trust.

Still the main topic

In general, DAOventures is facing 3 main problems:

  1. How to transfer tokens between chains, not just exchanges;
  2. How to reliably verify cross-network transactions;
  3. How to reliably control blockade and unlock operations.

Only by making a breakthrough in these three challenges can we transform the current blockchain patchwork quilt into the true Internet of Web3 tokens of the future.

Darwinia Network has made a real contribution to solving these problems.

Darwinia ChainRelay is a lightweight client that integrates MMR cryptography technology so that every validated block header is aware of the state of the historical chain. It also implements an internal optimistic validation process to determine the longest chain. It supports on-demand forwarding, which is triggered by the port initiator. This is economically viable and completely unreliable. With such an efficient relay chain, DAOventures can build two-way decentralized bridges across Turing complete blockchains.

Let me walk you through the whole process:

Let's say you now need to transfer your tokens from Darwinia to Ethereum.

First, you need to lock your assets in the original Dariwnia chain, the backup contract on Darwinia will do the job without any intermediaries, solving the problem of how to control the locking operation and unlocking of the property in an unreliable manner.

In this case, the transaction will be sent to the target heterogeneous Ethereum chain. Darwinia Relay implemented in the problem chain will validate the transaction. The whole process is based on cryptographic technology, with no need for the trust of a middleman. So there will be no more problems verifying untrusted internetwork transactions.

Finally, the contract issuer will verify the Darwinia Relay to confirm the transaction and issue the same number of matching assets. The ransom logic would be the same. When it comes to technical innovation of Darwinia, you can move your assets across blockchains in a decentralized way.

As shown here, instead of building multiple straight bridges between each blockchain, consider the level of work overlap and the need to use only a single Darwin bridge chain to transfer assets to any target chain How much easier will no heterogeneity be.

How to do cross-chain transfers

Open https://wormhole.darwinia.network/ and click on Ethereum.

Then click the Cross-chain Transfer button in Darwinia to go to the Cross-chain Transfer page, select Ethereum -> Darwinia Mainnet from the drop-down list, then click Cross-chain Transfer. At this time, a window will appear, prompting you to connect to and choose an Ethereum address containing darwinia assets (make sure there are enough to pay your network gas charges), click Next, then Connect.

After successfully connecting to the metamask, a form will be displayed. Fill in the correct “Darwinia Network account” (address starts with the number 2), select the “asset type” and enter the transfer “amount”, click “Approve” (when using the cross-bridge for the first time) , there will be an “Approval” step), click “Submit” In the metamask popup:

After finishing “Approval”, click “Submit” button and click “Submit” in the metamask popup, the page will navigate to:

That's all you need to do.

And the next step is to wait for transaction confirmation on Ethereum and Darwinia. Click on “Cross Chain History” to see the progress of the transfer confirmation:

After confirming the Darwinia transaction, you can click “Txhash” to open an additional scan and view the transaction details:

We can see that using the Darwinia Ethereum-Darwinia one-way bridge to connect to the internet is a very simple and easy thing to do.

Darwinia aims to be Polkadot's parachain

Since other parachains will be connected to Polkadot, achieving interoperability in Polkadot ecosystem, for example, we all speak the same language, there is no barrier to communication. But for heterogeneous blockchains outside the Polkadot ecosystem, they are like speaking a foreign language.

Darwinia Bridgechain will act as an interpreter and empower parachains in the Polkadot ecosystem with heterogeneous cross-chain capabilities so they can focus primarily on their own business.

Advantage of Darwinia

In addition to all of the above, another interesting advantage of the Darwin bridge circuit is the support for interchain NFT transmission. Let's say if you are asking for a lot of regular subscriptions just to transfer your CryptoKitties, then the commission barrier is really high. For xclaim's collateral-based solution based on price flow, there is no universal standard for valuing your NFT.

Dapps

What really excites you the most are the huge apps.

In general, Laveraging Darwinia, single-chain applications can be upgraded to a cross-chain version, including but not limited to the market , Gaming or NFT.

DeFi

For example, Defi apps like MakerDao can provide multiple collateral using quality assets from other blockchains, not just Ethereum.

Stable coins like DAI or BUSD could go beyond the standard and increase the number of users using blockchains like Polkadot and others. Ethereum's layout ability has shown its worth in the recent Defi farming trend. Users can also make profits through protocols. For example, you add liquidity to the Balancer with the tokens received from the Compound. There is a certain benefit to such cooperation.

Darwinia Bridging Chain will serve as key infrastructure to enhance cross-chain layouts, facilitate cross-chain crop farming, provide users with a new catalyst that will spark interest their interest in discovering new investment strategies.

NFT Market

The NFT market is gaining momentum in 2020 - 2021, but it is clear that much depends on what is happening with Ethereum. With Ethereum gas fees soaring, DAOventures definitely needs more options. Darwinia is not only providing cryptographic services, but also moving a single-chain NFT marketplace like to the multi-string version. One of the most interesting benefits of the Darwinia bridge chain is the way it supports NFT cross-chain transmission.
