Ensuring the transparency of public auctions
The Ministry of Justice of Ukraine and Bitfury have begun using blockchain platforms to hold confiscated assets auctions. The information about the course of trading, bids, and buyouts is recorded in the blockchain integrated with the platform. Anyone can check the progress and the outcome of an auction. The pilot project turned out successful, so both parties decided to gradually integrate the blockchain into other types of public auctions.
Blockchain will confirm all actions performed and exclude manipulations with information during the bidding process.

Recording auction information in the blockchain
The auction house Christie's (conducts 350 trades annually; in the first half of 2018, the volume of art objects sold amounted to $4 billion) has announced its intention to record the painting sale transactions on the blockchain. The blockchain system will be first used during the November auction "An American Place | The Barney A. Ebsworth Collection Evening Sale", estimated by experts at $300 million. The information about each lot (name, description, author, sale confirmation, date, and cost of the transaction) will be recorded on the blockchain. A digital certificate will be generated based on the data hash, and new owners of the paintings will be given access to it in order to confirm the authenticity of their property in the future.
Blockchain will guarantee ownership of art objects and the possibility of confirming its authenticity in the future.

Authentication
Product authentication
The Provenance platform is a packaged solution for manufacturers of goods that allows to increase the transparency of a supply chain. All product information that may be of interest to the customer is entered into the blockchain: for example, Martine Jarlgaard uses the solution to enter all product information "from the alpaca in Dulverton to the finished sweater" (part of the information is filled in by the manufacturers of materials). Users can scan the QR code on a product with an app and see where the wool, the yarn and the sweater itself were made. This forms a special value of the product for the buyer and increases their interest in it.
Blockchain is a guarantor of authenticity and integrity of information, apart from being a convenient tool for storing serial data and its change history.

Fuel payment automation
S7 and Gazpromneft-Aero Airlines have developed and implemented joint smart contracts, which increased the speed of mutual settlements related to aircraft refueling and also allowed to automate the planning and accounting of fuel supplies. Before refueling, an online application is sent to the airline's bank in order to reserve the required amount on the account. Successful refueling is confirmed by sensors from both parties, the readings of which must match. After the service is completed, the funds are written off, and the information regarding the application status along with all reporting documents is transmitted to the commercial services of the fuel supplier and the air carrier. The whole process takes about 60 seconds now.
Blockchain allows to create a trusted register of the refuelings and the amounts of fuel consumed; smart contracts integrated with sensors from both parties allow to automate the processes of checking readings and making payments.

Blockchain document certification
Stampery records a hash of any text file information (be it a document, a letter or messenger message history) in a Bitcoin or Ethereum blockchain (this is what the anchoring mechanism is essentially about). Stampery claims the ability to process 10⁹ data sets per second, extract their unique cryptographic identifiers, build a cryptographic tree with all this date and time stamped data, and publish the result (as a hash) into the blockchain. The solution is mainly oriented towards large companies that need to ensure the safety of circulated documents.
Blockchain is a network for storing generated hashes. The mechanism behind open blockchains will not allow changing the hash once it is entered, therefore proving the authenticity of documents.

Copyright confirmation in court
Proofstack is an app for the certification of documents. The service archives the document file together with the owner's personal signature and the timestamp. The archive hash is then recorded in the chosen blockchain. The archive created as a result of the certification confirms that the file was archived by a certain person at a certain time. The developers also recommend sharing files of this type through a specially generated link, informing anyone who downloads the file that it is the author's certified intellectual property. Therefore, the authentication of documents can theoretically serve as proof of copyright in court.
Blockchain is used to store hashes of archived files, which allows to confirm the creation of an archive at a specific point in time.
