• Heard about Bitcoin from a friend in college in early
2011 (BTC/USD ~10 each)
• Began Bitcoin mining in 2011, made several bitcoins
• Biggest regret: selling over 100 BTC < $1000 (today
value > $ 1m) 
• Bought some bitcoins in 2017 
• Traded on Bitfinex and Binance
• Second Biggest regret: Engaging with trading which
resulted in losing 80% of my initial coins due to recent
market collapse 

The Distributed Ledger Landscape
The Distributed Ledger LandscapeThe Distributed Ledger Landscape
The Distributed Ledger Landscape

This document discusses the distributed ledger landscape and who is developing shared, replicated ledgers and why. It outlines the characteristics of distributed ledgers and the motivations for building non-proof-of-work ledgers and private blockchains. Known, trusted parties are preferred over unknown, untrusted parties due to unclear governance and scalability challenges of public blockchains. Permissioned blockchains with legally accountable validators are seen as more suitable for settling off-chain assets like securities and fiat. While distributed ledgers provide benefits, their use cases depend on factors like whether participants are known or anonymous, and what type of consensus is required.

Blockchain and Smart Contracts (Series: Blockchain Basics)

Blockchain is a tool. Samson Williams likens blockchain to a group text message, in which each participant receives a distributed, time-stamped, tamper-resistant (and encrypted) record of data transactions. Each group text has these characteristics. Everyone in the group “sees” the data, and none can change or gainsay any group message. Smart contracts are computer code put on the blockchain (how, exactly?) that establishes self-executing terms and conditions of a transaction. Are smart contracts smart? If certain data comes in and fulfills a pre-set term or condition, then rights and responsibilities are formed, terminated, modified, or shifted among the parties. Ah certainty and transparency, but also ah garbage in and garbage out. Are some contractual terms not amenable to smart contracting? And are smart contracts necessarily contracts? If not, can they still be useful? If a smart contract is a contract, what is the governing document? Is it the words business people and lawyers use, or is it the code that is supposed to reflect the words?

BLOCKCHAIN & THE HOLLYWOOD SUPPLY CHAIN

The global system behind a viewer’s transaction of watching a movie or TV show impacts viewers and show creators every day. What if all stakeholders had the same facts – Writers, Producers, Directors, Unions, Studios, Networks, Distributors, Theaters, Broadcasters, Cable Providers, Satellite providers, OTT providers and viewers? Blockchains offer precisely this opportunity. In this article we are going to explore new methods for enabling accountability in pre-production, production, post production, distribution, consumption and reporting with a secure chain of custody and metadata to be accessed, including key social attributes such as viewing method, display usage, rights compliance, and digital rights management.
