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.

In general, SAP operations and all associated activities need to be further professionalised. This includes the documentation of key and mission critical processes and their verification for timeliness and validity. It is also necessary to record and describe the performance of the base by IT service management, as well as techniques such as a RACI matrix to identify and document the responsibilities of the SAP basis.

In the past, when we deployed SAP environments, we first had to work out a detailed sizing and architecture and pass it on to the procurement team, which then ordered the systems and installed them in the data center. From there, it went on to the network team, the storage team, the operating system team, and the database team. So it was not uncommon for three to six months to pass between the architecture design and the installation of a new SAP system.

"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP base.

Since SPAM runs within the SAP system, you do not need to know the operating system to handle the transaction.

An SAP expert is always familiar with the latest technologies.
