Web3 Foundation - The Next Evolution of the Internet - Dr. Gavin Wood
The internet has been viewed as transformative for society. But we are still effectively applying the same old business models and hierarchical structures to new technology. Dr. Gavin Wood, Founder of Web3 Foundation, Parity Technologies and Ethereum, explains why it's important for the internet to evolve into a truly decentralised web in order to allow for entirely new societal structures to be created.
Decentralized Oracles: Providing Access to Key Off-chain Data Sources by Sergey Nazarov
dotGo 2016 - Péter Szilágyi - Immutability in Go: Post mortem from a DoS-ed blockchain
Filmed at http://2016.dotgo.eu on October 10th in Paris. More talks on http://thedotpost.com The tried-and-true approach to sharing memory in Go is via communication. Yet there are scenarios where the amount of data is prohibitively expensive to pass around. Instead of falling back to locks, immutable data structures provide an alternative way, where we can achieve concurrent access to shared memory while at the same time make reasoning about complexity much easier.
Lecture 5: Blockchain-Related Data Structures and Concepts
Blockchain-related data structures and concepts - Hash pointers - Hash chains - Merkle trees
