Meanwhile, there are other ways to build consensus. But, for the most part, the following three options have proven effective as a consensus mechanism: 1) Proof of Work 2) Proof of Stake 3) Proof of Importance The differences are presented in another blog post. How do blocks form in a blockchain? Each block will build irrevocably on an older block. If you were to remove the block, you would also have to remove all blocks above it, which would destroy the entire chain of blocks. Because each new block also contains information from its predecessor block. This is very important for understanding the immutability of a blockchain. If you were to manipulate a block afterwards, you would have to adjust all the blocks that follow. The effort would be so infinitely large and expensive that such a manipulation can practically not be implemented. You can think of it as this. A blockchain arises from the cryptographically linked blocks (puzzles) full of transactions (puzzle pieces) and therefore cannot be changed without destroying the entire blockchain. For this reason, a blockchain is seen as an immutable transaction history agreed upon by a decentralised community. A blockchain is programmed to work with each miner on the longest part of the blockchain, as this is obviously the chain in which most of the work has been invested.
Once you sent the money person A and once person B. Which miner is right now? The solution is to divide the consensus into time blocks, in which a miner is randomly selected, and then determine which transaction it has selected as the consensus during this block. The transactions are stored in blocks of the chain. Only a limited number of transactions fit into each block. The miner, which solves the last transaction of a block before a new one is generated, also gets a bitcoin as a reward.

SAP recommends a role design for Fiori permissions based on the defined catalogues and groups in the launchpad. In such a catalogue there is usually a set of apps and services which is relevant for a specific user group. If a role for one or more catalogues in the launchpad has been authorised, the corresponding catalogues and groups will be displayed in the app finder only for eligible users when the launchpad is launched. This ensures that every user only sees what they are working with. Important: These Fiori permissions are maintained on the frontend server! Maintain catalogue permissions in the PFCG To add a Fiori permission to open a catalogue for a role, reopen this role in the PFCG in Change mode and follow the next steps: 1) Select Menu tab 2) Click on the small arrow to add an item 3) Select "SAP Fiori Tile Catalogue" Then select the corresponding Catalogue ID for which the selected role should be eligible. Now the role only has to be assigned to the corresponding users in the system. Once you have completed these steps, you will have the Fiori permissions you need to view individual tile catalogues on the launchpad.
The lifecycle of an SAP system begins with the installation of the database platform. This is installed by an SAP Basis administrator and can consist of one of the following databases: HANA, Sybase, DB2, Oracle, MSSQL and MaxDB.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
