Overview Portion is a digital and physical art and collectibles marketplace. Art and collectibles enter a new market thanks to Ethereum and IPFS smart contracts. DeFi (Decentralized Finance) connects artists and collectors directly, allowing them to effortlessly sell, invest in, and own artwork in perfect transparency. By merging blockchain technology with new procedures and operations, Portion is positioned to solve the constraints of traditional auction houses. The Portion marketplace is a free-to-trade marketplace for digital and physical products. When fully completed, the bid/ask mechanism will work similarly to a traditional stock exchange. By 2018, the platform has collaborated with over 30 galleries, many of which are still using its technology. Osinachi, Hackatao, Oficinas TK, Connie Digital, David Young, Kevin Abosch, and others were among the first cryptocurrency artists to use the platform (some of whom were auctioned live in 2019 at Ethereal Summit hosted by ConsenSys). By 2019, the team launched a real gallery in Manhattan, where it hosted several exhibits, auctions, and live events. Coronavirus (COVID-19) struck in March 2020, made them close the recently rebuilt gallery, and left them with little alternative but to refocus all of their efforts on the Internet platform. Digital Art and Collectibles Using a drag-and-drop online interface, artists may tokenize any media file. Portion hides the blockchain's backend and eliminates the need for plug-ins or third-party apps, making it accessible to both conventional artists and crypto aficionados. The vendor specifies the price they want for a certain piece on Portion, while collectors provide the vendor their best guess. The transaction is complete when a seller accepts a collector's offer. Portion's marketplace approach ensures that creators get paid fairly for their work. Furthermore, this approach helps the artist understand the market's need for and worth of his or her work. The marketplace model of Portion also emphasizes digital assets as a new form of expression with measurable audiences and values. Physical Art and Collectibles Consumers will get direct access to physical art, collectibles, and luxury products via Portion's marketplace. All posted items are accompanied by a blockchain certificate that verifies the beginning of provenance from the original supplier (artist, brand, etc.). The certificate and paperwork serve as an authentication certificate as well as a record of ownership and title. When an item sells, a digital version of the item, as well as the purchase payments, are kept in escrow. When the transaction is finished, monies are sent in return for the actual product, along with a blockchain certificate. Secondary Sales: IN-NETWORK (Futures) Portion proposes to permit futures trading of art and collectibles, much like any other stock exchange. Physical products can be delivered to the buyer, Portion's storage facility, or a selected storage partner. Because the blockchain certificate represents the transfer of ownership, buyers might opt to forego physically receiving the item and instead acquire it for its economic value. This concept allows customers to retain ownership of an item without having to worry about keeping it in excellent shape. Furthermore, this paradigm avoids the requirement for the good to be re-authenticated. Buyers can keep an eye on the market and relist the right to possess a product at any moment.If the future buyer desires actual ownership of the item, Portion will mail it to them.Ether, Porti (to reduce costs), Gemini Dollar (GUSD), and even fiat can be used to make transactions. Secondary Sales: OUT OF-NETWORK To assist with consignment auctions, Portion maintains a continually developing global network of thoroughly verified, respected appraisers and authenticators. Sellers will be able to authenticate, appraise, and acquire a Blockchain Certificate for their goods in any location (s). All partners are interviewed, have references provided, and must establish trustworthiness based on their credentials and affiliations. To ensure ethical and high-quality procedures, Portion continuously monitors the correctness and authenticity of Blockchain Certificates provided by the network of partners. Portion also plans to establish contracts with each network partner to protect against fake products and liabilities for all parties. Portion is able to retain a level of decentralization and size because to this method. Portion's user base will gain trust and convenience as a result of this strategy, while the organization's costs will be reduced. Portion wants to form direct connections with living artists. At the time of production, all artists and creators are offered the option of creating a Blockchain Certificate. The artist will be able to auction or sell their work on Portion after creating the Blockchain Certificate. To guarantee that commodities are real and adequately portrayed, Portion has developed a three-step process: First, appraisers and authenticators locate high-value items and prepare listings for them. The partner then distributes a Blockchain Certificate via Portion's administration dashboard after authentication. Finally, the seller may advertise their good(s) on Portion after acquiring the Blockchain Certificate, skipping any centralized, long inspection time. Technology Quite a number of high-tech features, have been embedded and integrated into the Portion platform in a bid to achieve a seamless operation. Smart Contracts To achieve optimal interoperability and modularization, many Ethereum (ETH) smart contracts are used. Smart contracts are transparent and open source by definition. All transactions are transparent, allowing for a free market in art and collectibles. Portion aspires to be a global decentralized financial (DeFi) solution based on open source technologies. The DEX for Art and Collectibles Portion created a decentralized market platform from the ground up with Solidity (a programming language for constructing smart contracts) and Web3 (technology to deliver user-friendly integration of blockchain on the web). As a result, cryptocurrencies have been used to create a worldwide marketplace where individuals from all over the globe may buy, sell, and make bids and asks on real and digital products. Order Matching When a buyer's and seller's orders are identical, the Blockchain Certificate and bitcoin automatically switch. The cryptocurrency is given to the seller, and the Blockchain Certificate is given to the buyer. Blockchain Certificate A Blockchain Certificate is a unique Ethereum-based standard used to authenticate the authenticity of tangible art and collectibles, such as ERC-721 or ERC-1155. The asset will connect the Ethereum and IPFS (InterPlanetary File System) distributed networks to redundantly store both ownership and related content (images, documents, videos). Using web3 and distributed technologies, verified artists, shops, and brands offer Blockchain Certificates through a secure online site. A smart contract creates a unique asset for a certain product, containing photographs, serial IDs, ownership metadata, and any other relevant information. If applicable, a Port can be irrefutably connected to a commodity, adding another degree of confirmation of authenticity. As the good is passed from entity to entity, the provenance becomes clear on the public ledger, decreasing the requirement for future authentication. Digital art and collectibles will be generated in the same way as Blockchain Certificates and will employ the same standard. Creators will be able to drag and drop their tokenized media asset onto the online portal, give it a unique name, add a description, and define the edition size. Provenance As the good is moved physically or digitally, the Blockchain Certificate is transmitted from entity to entity via Portion's smart contract ecosystem. The Ethereum blockchain acts as an unassailable global registry, storing all art and collectibles that have been properly appraised and/or validated. Ports Fraud-resistant holographic tags known as Ports can be used to connect the physical product to the Blockchain Certificate. Portion's ports are one-of-a-kind and can be scanned with a smartphone using either NFC or QR codes. Data may be acquired simply by scanning thanks to the use of Ports. The following is a list of information that may be retrieved: Owner’s Public key Sale History Provenance Associated Photos/Files - Additional Data If wanted, Ports add an extra layer of decentralized data that may now be directly associated with a physical commodity via the unique tag. A network of high-value items with complete control and authenticity becomes accessible and transparent throughout the world. Featured Artworks In terms of sales, Marvel and DC artists have done well on the site, and the collaboration with Essential Sequential is going well.
