Hashgraph is a third-generation super-fast distributed ledger that you can utilize to build decentralized applications (dApp). The nodes that are run by the Hedera Governing council including industry leaders, such as : Boeing, DLA Piper, Deutsche Telekom, IBM, Nomura, DLA Piper and more. To get a quick overview about the platform, read the getting started article here.

Unlike second generation blockchain/DLT platforms, Hashgraph does not mandate or restrict the users to build their applications using native crypto or smart contracts. There are many creative ways you can combine these various offerings of the platform to build the next generation applications. Here is the link to a case study on Hashgraph feature set. In addition to this, the recent article published by AdsDax on using decentralized messaging queue using Beanstalkd is an amazing hands-on technical read.

The implicit security is assumed by the fact that you can sign your transactions with the private key and that in the current realm of computing limitations, it’s not possible to cryptographically derive your keys.

To make things easier, most cryptographic key management systems/processes have implemented various…
