Vitalik Buterin via the Vitalik Buterin Blog This is a mirror of the post at https://medium.com/@VitalikButerin/a-proof-of-stake-design-philosophy-506585978d51 Systems like Ethereum (and Bitcoin, and NXT, and Bitshares, etc) are a fundamentally new class of cryptoeconomic organisms — decentralized, jurisdictionless entities that exist entirely in cyberspace, maintained by a combination of cryptography, economics and social consensus. They are kind of like BitTorrent, but they are also not like BitTorrent, as BitTorrent has no concept of state — a distinction that turns out to be crucially important. They are sometimes described as decentralized autonomous

The Tightrope of Regulation

In a significant move at the recent G20 meeting in India, the International Monetary Fund (IMF) and the Financial Stability Board (FSB) released a joint paper outlining a framework for the global regulation of cryptocurrencies. While the proposals mostly tread familiar territory, what’s new is their conviction in crypto’s unstoppable growth and success. A flurry of optimism greeted the G20’s endorsement of the report because it advocates that countries don’t ban crypto. Hidden in its text, however, are some worrying signs. For example, on the first page, they state, “Widespread

Bridging Real and Virtual Economies

In an era where decentralized finance (DeFi) promises revolutionary, permissionless, and credit-check-free access to financial services, the limitations to its application lie in the narrow range of digital assets it encompasses.

Beyond the Dollar

The global economy is at a crossroads with the US dollar’s future as the world reserve currency facing fresh challenges. For decades, the stability and dominance of the dollar have given the United States significant advantages in global trade, investment, and geopolitical influence. However, as emerging economies like China and India rise in prominence, their currencies are gaining traction in international transactions, challenging the dollar’s hegemony. China, in particular, has been busy over the past few months, actively promoting the Yuan and seeking to challenge US dominance in the global
