Notes on highly secure software architectures

The basic architectural elements of Blockchain give the possibility for realizing highly trusted and secure computational architecture, even if they are not manifested in a decentralized peer 2 peer manner. Elements of the secure computation are the basic cryptographic elements, like public and private key infrastructures or hash functions. Services of such a highly secure architecture might be: - secure computation: for certain critical computations the requirement to sign either the computation or the result with multiply keys of multiply actors. 
- secure data structure: for the data structures to be organized in a hash structure, implying hash pointers showing to the result of other hashed data elements, providing a highly hacker resistant data structure. 
- proof of work: putting proof of work into the system implying that the security system will be more resistant against exhaustive search attacks. 
- secure architecture: combining the previous elements together to form a highly secure, highly hacker resistant software architecture.
