noun | bee·kuhn cheyn
The shining beacon of hope for Ethereum's scalability woes, or the world's most expensive participation trophy, depending on who you ask. The Beacon Chain is like the cool kid's table of the Ethereum ecosystem - everyone wants a seat, but nobody's quite sure how to get one.
Example
"I staked my ETH on the Beacon Chain because I believe in the future of Ethereum. Also, my wife's boyfriend said he'd give me my Nintendo Switch back if I did it."
"The Beacon Chain is live! Only 5-10 more years until we can actually use it for something!"
