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.
A role concept according to best practice protects you from potential attacks within your SAP landscape. However, to protect your system from unauthorized access via the network, the SAP Gateway must be configured correctly. It enables the use of external programs via interfaces or the call of ABAP programs and serves as a technical component of the application server, which manages the communication of all RFC-based functions.

I recommend that you schedule the background job PFCG_TIME_DEPENDENCY with the report RHAUTUPD_NEW. Scheduling the RHAUTUPD_NEW report with two variants has proven to be a best practice: Once a day before users log on for the first time (e.g. midnight or very early in the morning). This way the users are synchronized once a day. Once a month (or even once a week) with the option "Perform cleanup", so that obsolete profiles and user mappings are regularly cleaned up. Also handy: If the naming conventions of your roles allow it, you can also align the report according to different time zones. For example, I have a customer who runs the user synchronization for his users in the USA and Asia at different times, so that the daily business of the respective users is not disturbed.
Costs: 75% savings on subsequent corrections. Significant reduction in development and maintenance costs. ABAP code: 84% faster and more fail-safe programs. Improved performance reduces runtime and hardware utilization. Targeted corrections minimize system errors and downtime.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
