Show HN: Decentralized Database DB3 is a community-driven layer2 decentralized database network. Infinite Storage Space Scalability is the key to the web3 explosion, db3 will use the following strategies to achieve web3 scale PC can meet the minimum system requirements so everyone can join the db3 network to provide storage space. Using dynamic sharding to achieve scale out. when a storage shard chain has not enough space to store mutation, it will split itself into two subchains. Using cold data archive to recycle storage space. history cold blocks and cold state data will be archived to FileCoin and the storage node will always has storage space to store new data. Blazed Fast and Provable On-chain Query Currently, decentralization means bad performance but db3 is trying to make a big improvement in performance Merkdb is the storage engine of db3 network and it not only has high performance but also the fast-proof generation Geo distribution, the nodes in every storage shard are geo-distributed and the clients can execute querys against the nearest storage node Query session, the first decentralized query protocol to resolve performance and incentive perfectly Crypto Native Data Ownership In the decentralized network, only the private key owners can update their data and they can keep privacy by encrypting their data with the public key On-chain Programmable Dapp developers can develop data processing contracts and deploy them to the db3 network just like developing data backend in web2 Ethereum Guarded Security DB3 network is a layer2 network on Ethereum and all the assets are guarded by Ethereum https://ift.tt/VO2umHU December 22, 2022 at 07:34PM
Show HN: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
