IOSG Web3.0 Berlin Project Library (Middle): See the rise of Dapp in Europe and the revival of DAO

, reprinted by Odaily with authorization.

During dAppcon, we got an in-depth look at projects developing dApps on ethereum, discussed state channels, and participated in 24 technical workshops before the EthBerlin Hackathon to share knowledge with everyone.

Vitalik Buterin twice surprised Dappcon attendees, once he appeared on stage as a fox, beckoning the audience to think about the complexities of "meme-driven development": Memes can be a business model ? Later, Buterin joined Joe Lubin, Stephen D. Palley, and Ryan Selkis on stage to discuss the blockchain community Ethereum and its impact on society. [1]

The Ethereum-based trading system is applied to the Golem platform to settle the income of computing power providers and the fees that computing power users need to pay. Users can buy and sell computing power through this network, which means that users can trade in other people's Completing the work that requires computing power on the computer, or selling your idle computing power to those who need it. Golem is composed of all nodes running Golem applications in a completely peer-to-peer manner, and can be used to simulate stock markets, big data analysis, medical research and even cryptocurrency mining. Golem leverages an Ethereum-based transaction system to resolve payments between providers, requesters, and software developers. All calculations take place in a sandbox environment and are completely isolated from the host system.

The P2P decentralized trading platform on Ethereum uses the Swap protocol to provide a decentralized trading solution based on peer-to-peer transactions. Its core services include a searchable trader index mechanism with "trading intent" and a pricing mechanism, as well as smart contracts that provide on-chain execution transaction settlement functions. For those looking to trade ERC-20 tokens, the index will be a destination for advertisements of what they want to trade and to search for other traders. Once the transaction intention of the other party is found to be suitable, the two parties to the transaction can communicate directly point-to-point. To assist the pricing process in communication, Pricing Mechanism provides pricing recommendations generated from multiple data sources. After the two parties communicate and determine the price, one party places an order, and the other party submits the order to the smart contract for on-chain settlement. AirSwap intends to eventually attract the attention of large institutional investors such as DRW holdings LLC, DV Chain and other traders.

ditCraft initiates a new governance of open source project development. If Gas fees power Ethereum, Code is the fuel for decentralization. The development of an open source project is usually controlled by a small group of people to prevent anyone from performing malicious changes to the code. But these people tend to steer development in a certain direction that they think is best. In some cases, this control prevents others from contributing to the project for various reasons. There are even bugs in stable versions, such as Linux kernel 4.8 or the famous Heartbleed bug in OpenSSL, because the developers or reviewers who control these changes are not experienced enough.
