Curious to see everyone level of understanding of this massively hyped up word "Blockchain"

Explain what is blockchain in less than 15 words, sending 25,000 sats to the best answer

Ledger of recorded information that is impossible to change or modify and backed by computers

it's the new dot com bubble, current decision makers are exactly old enough

Digital ledger immutable to change information or values through computing power by/for the people.

Blockchain is a digitized, decentralized, and continuously growing public ledger that consists of records called blocks, which are linked and secured using cryptography.

ISO more opinions! Some nice take so far

umad

Anything but art

Explaining something in less than 15 words will only lead to fucking stupid answers

Its an open market fan boy's wet dream, but a government and bankers nightmare as they lose controls over the power of purse. In theory blockchain backed systems should be near free to execute/facilitate a transaction when compared to traditional systems, but reality is far from that fantasy. Investors/banker middlemen always angling to get some kind of cut. Many pseudo-blockchain or pretend-wallet services being peddled around.
