>Noteworthy in connection with the development in the field of interoperability of block chains is standardization. At the beginning of the Internet era, the standardization of a few Internet protocols carried out by standardization bodies in ARPA, universities and research centers around the world. Then developed on the basis of standardized protocols more and more applications. In the process of development of blockchain technologies, the blockchain standardization takes place in a different order: We experience many years the emergence of more and more protocols and a slowly increasing number of applications. The standardization by international bodies or in the course of cooperation but succeeds in time. Technical development need also exists with regard to the so-called Oracle. This marks the transition between the blockchain world (on-chain) and the non-blockchain world, which includes traditional information systems and the physical world. allow Oracle, for example, to transfer data off-chain such as a temperature value or a delivery number in a smart contract and thereby interact with the contract logic. So they allow the interaction of Smart Contracts and data from other systems, thus forming a kind of link layer. In order to maintain the high safety properties of blockchains, Oracle must ensure a secure and reliable communication between different systems. (The Crypto Oracle (2018)) Most current Oracle services providers have some basic points of attack, so new approaches are being tested. (See. For example, chainlink, https://chain.link/))
