When was golem released?

I'm curious about the history of the cryptocurrency Golem. Could you please enlighten me on the question, "When was Golem released?" I've heard about its potential for decentralized computing power, but I'm not sure when this innovative project first came to light. Understanding its timeline would help me grasp its evolution and significance in the crypto space. I'm particularly interested in knowing if it was an early entrant or a more recent addition to the growing list of cryptocurrencies. Thank you for your assistance in answering this query.
