‘The Bitcoin and Blockchain Technology Explained’ (video)

Henrik, Rodrigo. “A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency’s block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history. Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block’s hash…

‘[Blockchain] is to Bitcoin, what the internet is to email’

Thompson, Collin. “Blockchain’s decentralized, open and cryptographic nature allow people to trust each other and transact peer to peer, making the need for intermediaries obsolete. This also brings unprecedented security benefits. Hacking attacks that commonly impact large centralized intermediaries like banks would be virtually impossible to pull off on the blockchain. For example — if someone wanted to hack into a particular block in a blockchain, a hacker would not only need to hack into that specific block, but all of the proceeding blocks going back the entire history of that blockchain. And they would need to do it on every ledger…

‘Bitcoin: A Peer-to-Peer Electronic Cash System’ (pdf)

Nakamoto, Satoshi (image: Ogilvy). “A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of…

CaaS: Country As A Service

It’s called CaaS. There’s SaaS [software as a service ]. We’re country as a service. That’s the ambition. It started about a year ago and we’re at about 10,000 users at the moment. So in startup terms, that’s quite significant (Business Insider).
