Today marks a symbolic anniversary: exactly 17 years ago, the very first Bitcoin transaction was validated on the blockchain. Satoshi Nakamoto sent 10 BTC to Hal Finney, laying the foundations of the peer-to-peer network that would revolutionize decentralized finance. This moment, seemingly trivial, represents much more than a simple transfer: it is the first genuine exchange of the protocol we know today, proof that Bitcoin was not just a theory. Hal Finney, a key figure in the early days of the project, contributed to the development of the network from its very beginning. Seventeen years later, this inaugural gesture continues to remind us how it all started—with a simple vision: to create a monetary system without intermediaries.
