A Google search shows a great deal of activity in this area. As the time required to complete the development of post-quantum cryptographic algorithms will be long, and the time to adopt the resulting standards worldwide will be long, and the time to deploy systems compliant with the adopted standards will be long, quantum computers might be available before a QC-resistant PKCS system is deployed throughout the world.

Organizations with high security needs should deploy cryptographic systems based on conventional cryptographic algorithms until such time as quantum-resistant algorithms become available. Researchers in molecular nanotechnology are more aware than most of the truly remarkable medical advances we can expect in the next few decades. The ability to arrange and rearrange atoms and molecules in most of the ways permitted by natural law will enable revolutionary capabilities, including the full power of a mature nanomedicinewhich should make good health the birthright of all humanity.

Disease, disability, and the infirmities of old age will become rarities; joining polio, the plague and smallpox as ancient pestilences finally laid to rest by the inexorable advance of technology. While some of us might have the good fortune to stay alive and healthy until these medical marvels are available, cryonics offers a bridge to the future in case we wouldn't otherwise make it.

Should our health fail we can be cryopreserved and cooled to the temperature of liquid nitrogen. At that temperature, tissue remains essentially unchanged for centuries. We can preserve ourselves for the few remaining decades until the day when nanomedicine can heal our injuries and restore our health: as good or better than the health we enjoyed in our 20's or 30's.

For further information, see my web page on cryonics or my video introduction to cryonics. My wife and I joined Alcor the world's leading cryonics organization in This system allows two parties to exchange secrets by exchanging messages, even if they have never exchanged secrets before, without anyone else overhearing their exchange.

In other words, the communication between the two parties makes it possible to create a shared secret key that is impossible for a potential intruder to deduce. It is an idea that plays an important role in the Merkle Tree. It is safe to say that the Merkle Tree is one of the reasons why blockchain technology has become so successful today. It is a way of structuring data that allows to verify the accuracy of a large amount of information in an extremely efficient and fast way.

Basically, the Merkle Tree takes a huge number of transaction IDs and runs them through a mathematical process that results in a character code, which is called the Merkle Root. Merkle Root is vital because it enables any computer to quickly verify that a specific transaction took place in a specific block as accurately as possible.

No wonder then that Merkle, with his Tree, has changed the world of cryptography, including the way encrypted computer protocols work, becoming a crucial component of the technology that today underpins cryptocurrencies.
