130 projects in 30 days: Take a look at new ideas powering Web3.



After a month of workshops, lectures, AMAs, and low-key building, 134 teams submitted their final projects for the inaugural HackFS hackathon, showcasing fantastic tools and services that drive the distributed web. A total of more than 470 hackers from 50 countries in 19 time zones participated in the 30-day virtual event. On August 18, ten finalists presented their projects in front of the judges: Juan Benet, founder and CEO of Protocol Labs, Molly Mackinlay, project lead of IPFS, Pooja Shah, product lead of Filecoin, and Ken Ng of the Ethereum Foundation . You can watch the entire session and read more for a summary of the 10 finalist teams' entries. Application class Sailplane Sailplane is a peer-to-peer file storage service in web applications using IPFS and OrbitDB, similar to Dropbox. It uses IPFS and custom OrbitDB storage to store file metadata and other file management functions. The front end is built on React.js and has a custom browser-based user interface. The TVL of the Ethereum bridge fell to US$5.77 billion, a drop of 13.8% within 30 days: Jinse Finance reported that according to DuneAnalytics data, the current TVL of the Ethereum bridge reached US$57.7, a drop of 13.8% within 30 days. Among them, the five bridges with the highest lockup volume are PolygonBridges ($3.026 billion), ArbitrumBridges ($1.279 billion), OptimismBridges ($828 million), FantomAnyswapBridge ($229 million), and NearRaibow ($165 million). [2022/12/24 22:04:13] Sailplane uses IPFS to store, send and reference data. Custom OrbitDB storage takes output from IPFS and creates a mutable filesystem-like structure from it. This structure stores the path and file CID. When a user uploads a file or folder to a website, it is added to IPFS. The output is fed to the OrbitDB store, which allows mutations to the structure and replication of changes between devices. The site also allows for later downloads of the structure, be it a file or a folder. Learn more about Sailplane and watch a demo on the Filecoin blog. PAN Protocol The Public Annotation Network (PAN) is an open source Web annotation service that enables users to annotate content-ethexc on any web page and read annotations posted by others. There are two ways to submit annotations: users can directly publish annotations to our network, or submit through publishers, and then the publishers publish annotations in batches on behalf of users. Glassnode: Binance has outflowed $3.2 billion in stablecoins in the past 30 days: Jinse Finance reported that among all exchanges tracked by Glassnode, stablecoins have cumulatively outflowed $4.8 billion in the past 30 days, of which Binance has outflowed $3.2 billion , accounting for 66% of stablecoin outflows. [2022/12/16 21:48:09] Annotation data is stored on IPFS. In order to be better compatible with other services, PAN adopts W3C's Web annotation data model. An Ethereum smart contract registry is used to store references to each annotation and its annotators, ensuring that annotation data is immutable. Pnlp (pronounced "pulp") Pnlp is an open publishing platform for written content-ethexc on the Web3. Authors can write and publish on the open web, gather attention, and even earn money from readers. Subscribers can browse the best writing on the open web and support the authors they value most. Pnlp uses its own identity module to generate libp2p identities from Ethereum addresses, thus connecting the IPNS keyspace to the Ethereum address space. The browser app interacts with IPFS and IPNS using Textile Buckets hosted on Textile Hub. BlockSig Bitcoin mining revenue up 180% in 30 days: According to Crypto Parrot, Bitcoin mining revenue surged 179.4% in the 30-day period between June 27 and July 26, from 13.06 million The U.S. dollar rose to $36.49 million. During the 30-day period, cumulative revenue was $841 million. (finbold) [2021/7/29 1:22:57] BlockSig is a notarized document signing solution. The notary issues a document signing invitation, which when accepted by the involved parties generates a unique document token. Transactions on the contract represent state updates corresponding to each party, adding their signatures to the document. Once other parties have confirmed the signature, the notary's signature is the final step in the lifecycle. Once finalized, signature proof hashes from all parties are appended to the original document, and the resulting document is kept on IPFS as encrypted content-ethexc and mailed to all parties. An open-source verification tool reconstructs the intended proof and compares it to an uploaded file representing the final state. Infrastructure class Valist Valist is a decentralized binary distribution project with software notarization capabilities. Valist allows developers and organizations to register public certificates to securely publish and distribute software, firmware and arbitrary data to users. The idea is to leverage Ethereum, IPFS, and eventually Filecoin to create a common "base" layer for a simplified binary repository that both integrates with traditional package management systems and is built on top of a decentralized protocol. Smart contracts on Ethereum manage the latest source of truth for binary data stored in another layer (e.g. IPFS and/or Filecoin). Clients can then query the software notary for the latest version of some software and point to a verifiable decentralized data store. The total circulation of BTC anchor coins has exceeded 10,000, an increase of 125% in the past 30 days: data shows that the total circulation of BTC (BTC anchor coins) based on Ethereum has exceeded 10,000, and a total of 12,004 BTC anchor coins have been issued The fixed currency has increased by 125% in the past 30 days (5336 coins), including WBTC, renBTC, HBTC, imBTC, sBTC, pBTC and BTC++. Among them, WBTC has the highest share, with a current circulation of 8830, accounting for 73.56%, followed by rebBTC, with a circulation of 1158 (9.65%). (Debank) [2020/7/3] IPFS Recovery IPFS Recovery is creating a way for content-ethexc to remain on IPFS, even if the data and the entire network is damaged. This project implements erasure coding in IPFS by creating data block redundancy in IPLD DAG format. IPFS Recovery uses Reed-Solomon codes along with novel Alpha entanglement codes to achieve the end result, making files stored on the IPFS network more resilient. The goal is to have a modular framework where multiple erasure codes can be added. Alpha entanglements are especially interesting because they offer the ability to create self-healing networks. PlanetFlare News | EarnBetCasino team (formerly EOSBet) announced that the CPU will leave the EOS mainnet if the CPU cannot be resolved within 30 days: According to IMEOS reports, due to the current state of EOS, the EarnBetCasino team (formerly EOSBet) has announced that if the situation cannot be resolved within 30 days, they will Will leave the EOS mainnet. They see this as a governance issue, not a resource allocation issue, and hope that EOS can resolve it. [2019/11/27] PlanetFlare is a platform that creates a decentralized data retrieval market by enabling anyone with a computer to serve assets (similar to edge points on a CDN) and pay for this service. platform. Content publishers can host their assets on PlanetFlare and bid for CDN availability by specifying a price. An open marketplace reduces the cost of content-ethexc distribution and enables CDNs to distribute more globally, as the service does not need to be limited by centralized server locations. "We built the Web3 WebAssembly (WASM) runtime for a universally compliant smart contract API," explained Jordan Ellis, a member of the developer tools class Web3API team. "This allows protocols to implement user-friendly wrappers in a language-agnostic manner." These WASM modules, paired with subgraphs for historical data queries, are combined to create a single GraphQL schema that defines the ensemble of the protocol, which the team dubs "Web3API." Web3API is hosted on IPFS and is addressable using the Ethereum Name Service (ENS). They can be queried from any language or platform (node, browser, C#, C/C++, Rust, Go, Python, etc.). Decentralized applications only need to include their lightweight clients to query any Web3 API. The end result: "We were able to bring smart contracts into the API with incredible speed," Ellis said. Decentralized Docker Hub Decentralized Docker Hub powered by Powergate lets you push and pull Docker images from IPFS and Filecoin. It also supports ENS domain names using the IPFS hash of the docker image set as the content-ethexc hash of the ENS domain. "I decided to work on decentralized Docker Hub because I thought we needed an alternative to centralized Docker images," said Viraj Anchan. "Relying on a single, centralized source of docker images is risky, because if you delete an image, it will affect all your dependencies." Decentralized Docker Hub utilizes IPFS for hot storage and Filecoin for cold storage. Watch a demo. Pygate Pygate is a gateway to the Filecoin network and IPFS technology for Python users. While most of the tools to date have been aimed at JavaScript and Golang developers, the pygate team found that Python was overwhelmingly voted the "most wanted" language in Stack Overflow's February 2020 survey of more than 65,000 developers . The pygate team is helping bring Filecoin to this community by building Textile Powergate's interface and tools in Python. Pygate's solutions include Python API clients, sample applications, and more! In addition to the 10 finalists, each HackFS sponsor also awards awards to teams that use their technology in novel ways. Protocol Labs recognized 8 projects as recipients of the Protocol Labs HackFS Awards.
