Will Blockchain's Economy and Administration Revolutionise? What is a blockchain? A blockchain is a complete and unchanging transaction history of all transactions of a decentralised community that everyone who is part of it agrees to. The word blockchain first fell in connection with Bitcoin as a decentralised network for payments in the digital currency of the same name. The blockchain describes an underlying technology in which all transactions are publicly and unchangeably recorded. This transaction history is updated periodically. Each participant in the decentralised community accepts it as a reality, stores it on their computer, and can thus ensure at any time that no one can duplicate expenditure, as this would lead to a conflict in the transaction history elsewhere. A peculiarity of blockchain technology is that it has solved the "Double Spending Problem". Double-spending means something that can be doubled, and by 2008, only one central institution was considered to be sustainable. Double Spending can best be understood using the example of an image on a mobile phone. When I upload it to Facebook, I made a copy of it and I can upload it to Instagram, for example. So I used my picture "double". This effect made it impossible to establish a trustworthy, decentralised digital currency by 2008.
In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.

If we look at the question of standardisation, this concerns not only the administrative side of IT products, but also the standardisation and simplification of IT products offered by the SAP basis. For this purpose, tools such as ITIL for standardised tasks and the development of IT product and IT service catalogues have already established themselves to the greatest extent possible. These clearly describe the IT services provided. In addition to the definition of the service to be provided, the clear description shall include the identification of disclaimers and conditions that must exist. Also part of the service description is a price that can be composed of fixed and variable parts. This simplification and bundling of the product portfolios should also reduce the administrative burden when ordering, activating, changing, terminating and, of course, invoicing. The description of the IT services and the associated development of an IT product catalogue is the basis for standardisation, whether the recipient is an external or internal customer (e.g. a business unit). One difficulty is the definition of IT products, i.e. the pooling of IT services and resources. An orientation towards the idea of cloud computing can help. The characteristics of cloud computing are the provision of standardised services in terms of performance and type of performance, results-orientated services, provision of performance to a wide range of service customers, scalability, transaction-based billing and high risk of IT service failure.
To display custom tiles based on catalogues and groups when the launchpad starts, permissions are placed in the menu of the underlying role. This makes it possible to ensure that every user on the launchpad can only see and open their applications. Open Launchpad permissions SAP provides default roles for opening the Fiori Launchpad. This distinguishes between the Fiori permissions to start the launchpad normally and to manage the user interface.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
The use of eCATT and CATT should also be at least restricted, as allowing them can lead to significant database changes.
