"Truth happens. We will succeed. Don't wait around for others to take action. We must dive head first without regard for consequences, and break the inertia of passivity." — Amir Taaki (The libbitcoin Manifesto, 2013) #resistance #freedom

"It is important to realize that while distributed consensus is a hard problem, ordinary consensus is much easier and better studied, and can be solved some trillions of times more efficiently by use of trusted identifiable signing parties. Therefore, cryptocurrencies which compromise by introducing trusted parties, even under limited circumstances, should consider whether their new trust model is one for which consensus is easily achieved by some other mechanism." — Andrew Poelstra (On Stake and Consensus, 2015) #consensus #trust #cryptocurrency #bitcoin

"Security is a process, not a product." — Bruce Schneier (Secrets and Lies, 2000) #security

"I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it." — Hal Finney (Bitcoin and Me, 2013) #cryptography #cypherpunk

"I believed in the idea of giving people the freedom to buy and sell and connect with each other without the all-seeing eye of government watching every move." — Ross Ulbricht (Letter to Judge Forrest, 2015) #freedom #privacy

"WE STAND TODAY on the brink of a revolution in cryptography." — Whitfield Diffie and Martin E. Hellman (New Directions in Cryptography, 1976) #cryptography #revolution #privacy #publickey

"Cash is more than a method of payment. It is a fundamental tool for individual privacy and autonomy, and it is necessary for an open society." — Jerry Brito (The Case for Electronic Cash, 2019) #cash #privacy #autonomy #opensociety

"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." — Eric Hughes (A Cypherpunk's Manifesto, 1993) #privacy #secrecy

"A smart contract is a set of promises, specified in digital form, including protocols within which the parties perform on these promises." — Nick Szabo (Smart Contracts: Building Blocks for Digital Markets, 1996) #smartcontracts #digital #protocols

"If you see a proposal for an electronic money system, check to see whether it has the ability to preserve the privacy of financial transactions the way paper money does today. If not, realize that the proposal is designed to harm, not help, individual privacy." — Hal Finney (Protecting privacy with electronic cash, 1993) #digitalcash #privacy #warning

"What if everyone believed that law-abiding citizens should use postcards for their mail? If a nonconformist tried to assert his privacy by using an envelope, it would draw suspicion." — Philip Zimmermann (Why I Wrote PGP, 1991) #privacy #encryption #conformity

"I am an engineer, not a mathematician. I try to find practical solutions to actual problems." — Philip Zimmermann (GrepLaw, 2003) #cryptography

"If privacy is outlawed, only outlaws will have privacy." — Philip Zimmermann (Why I Wrote PGP, 1991) #privacy #encryption #law

"Cryptography can make possible a world in which people have control over information about themselves, not because government has granted them that control, but because only they possess the cryptographic keys to reveal that information. This is the world we are working to create." — Hal Finney (Protecting privacy with electronic cash, 1993) #cryptography #privacy #government

"Capable, generous men do not create victims, they nurture them." — Julian Assange (Cypherpunks: Freedom and the Future of the Internet, 2012)

"If cryptography's most basic aim is to enable secure communications, how could it not be a colossal failure of our field when ordinary people lack even a modicum of communication privacy when interacting electronically?" — Phillip Rogaway (The Moral Character of Cryptographic Work, 2015) #cryptography #privacy

"Talk is cheap. Show me the code." — Linus Torvalds (Linux Kernel Mailing List, 2000) #code #opensource

"Computer technology is on the verge of providing the ability for individuals and groups to communicate and interact with each other in a totally anonymous manner." — Tim May (The Crypto Anarchist Manifesto, 1988) #anonymity #privacy
