When it comes to cryptography I love these following sections from Cypherpunk Manifesto (https://www.activism.net/cypherpunk/manifesto.html)

Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world.

Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy.

I am excited to have Steve Swing, CTO of substratum.net to share his passion on cryptography and how for example it is used in digital wallets in our next meetup(https://www.meetup.com/The-Columbus-Blockchain/). Here is the abstract:

Cryptography is important. Cryptographic technology used in cryptocurrency wallets is especially important when protecting digital assets. During this talk we will look at several standards that define how cryptocurrency wallets work; how a wallet can seem to have “endless” wallet addresses yet without collisions. Learn strengths and weaknesses comparing hardware, paper, cold storage, and brain wallets. Learn steps to take to ensure wallets are kept secure and protected from cryptocurrency loss and how to recover from a lost, stolen or damaged hardware wallet. See Electron and Docker demonstrations of safe offline use of MyEtherWallet and BIP39 mnemonic phrase applications.
