    This clip is perfect. As a person who lived in Argentina, I know nobody trades back bitcoins or USD to pesos, except for buying stuff.

    RSK is not a coin. RSK is not a technology. RSK is not a federation. RSK has no price. RSK has no marketing. RSK is essentially a bitcoiner community that wants to maximally expand Bitcoin functionality while keeping Bitcoin core values intact. That's why we can only win.

    Nice RSK Ecosystem growth. Each week, a new star in the night sky map. The sun in the center is RSK. To the Sun!!!!

    I spent from 2012 to 2015 designing alt-coins to understand Bitcoin design choices. I could outperform Bitcoin in every individual metric (fungibility, scalability, decentralization, latency) Here is the thing I learned: it doesn't matter if Bitcoin could have been better.

    My vision is a decentralized and open financial system. But what do I do every day for that ? I explore all crypto problems and publish possible solutions as fast as I can, even as drafts, to prevent core technologies get patented by old corporations. I'm far from sleeping well.

    Cryptography is more fun than ever. Thanks to Bitcoin.

    I feel so happy. I know that Bitcoin can scale to serve 400 million users and I won't need to ask permission to anyone to scale it.

    I will say it one more time.. (some people never heard about RSK even if it's been working for 2 years!) *** RSK is DeFi for Bitcoin *** Bitcoin centered. No other native token. Merge-mined. A pro-decentralization community (drivechain BIP, snarkchain BIP in preparation)

    Bitcoin mining hashrate is at all time high! And @RSKSmart surpassed 51% of the miner engagement. A truly historical moment!

    Replying to @paritytech
    The attack is simple: you send to a Parity node a block with invalid transactions, but valid header (borrowed from another block) The node will mark the block header as invalid and ban this block header forever but the header is still valid.

    I've re-mined the first 18K Bitcoin blocks...but not to revert the blockchain. Then, why?

    The Patoshi Mining Machine
    One of the topics that has been debated endlessly is what kind of hardware Satoshi used for mining. Some people argue he only needed a single computer using the latest generation of Intel processor…
