This historic day marked a crucial moment in the world of "altcoins". The idea of the Ethereum blockchain and the basic cryptocurrency ether opened the way to a new way of confirming transactions, by moving from the current "proof-of-work" system to a more economical, faster and simpler "proof-of-stake".
On this day, we remember the visionary achievement of Vitalik Buterin, whose work and influence on the crypto community played a key role in the development and expansion of the Ethereum blockchain.
