    Coinbase’s Applied Researcher, Yehuda Lindell, has won the prestigious “Test-of-Time” award for 2022 from the International Association of Cryptologic Research (IACR). The “Test-of-Time” award recognizes papers published 15 years ago that have had a lasting impact on the field of cryptography. Yehuda’s pioneering work was published a year before another important paper you may be familiar with: “Bitcoin: A Peer-to-Peer Electronic Cash System”.

    His 2007 paper, “An Efficient Protocol for Secure Two-Party Computation in the Presence of Malicious Adversaries,” was the first to outline a two-party multi-party computation (MPC) protocol that was efficient enough to be implemented. In layman’s terms, secure two-party computation allows two “people” to solve a problem while keeping critical information private. For example, it solves the classic millionaires’ problem by allowing two people to understand who has more money without revealing their respective net worths. Yehuda’s work laid the foundation for future practical constructions.

    Why cryptography is critical

    Beyond their shared etymology related to something “hidden” or “secret”, cryptocurrency and cryptography are very intertwined. Cryptography’s mathematical and technological innovations underpin the entire crypto industry. The Bitcoin white paper makes this clear by introducing a cryptographic protocol in place of a trusted third party to validate transactions. This shift makes decentralization possible by “allowing any two willing parties to transact directly.”

    Cryptography is essential to enabling transactions that are anonymous, secure, and “trustless.” The final point is the least obvious and perhaps most important. You don’t need a bank, credit card company, government, or other third-party intermediary since cryptographic tools such as public-private key encryption provide secure, direct confirmation.

    Coinbase invests in fundamental research

    Coinbase cares deeply about the security and reliability of our systems and the crypto industry as a whole. Investing in fundamental research is a core part of our mission to increase economic freedom in the world. We are honored to have Yehuda on our team and to support research that advances our mission.

    Bitfinex whale flips to sell mode

    Data from Cointelegraph Markets Pro and TradingView confirmed BTC/USD hitting multi-week highs of $45,137 Friday as Wall Street got underway.

    As $45,000 reappeared for the first time since the start of the month, however, so did all-too-familiar behavior among some of Bitcoin’s biggest investors.

    Attention turned to exchange Bitfinex on the day, a platform famous for large-volume traders, or whales, guiding short-term price action with their trades.

    As noted by popular trader Pentoshi, the entity which had purchased BTC at the last low near $34,000 had now put in a significant ask position beginning at $45,000.

    Blockware lead insights analyst William Clemente agreed, telling Twitter users that it was now “popcorn time” for the market.

    For Cointelegraph contributor Michaël van de Poppe meanwhile flagged “a dozen” possible lower price targets should BTC/USD sweep liquidity at previous rejection points from March, these also lying just above $45,000.

    “I’m not saying I’m bearish at this stage, but while we’re making this build-up, I’m not really interested into longs at this point,” he said in his latest YouTube update.

    Only a rechallenge of $50,000, he added, would form the impetus to consider long positions.

    “No longs” on Ethereum, says trade

    Van de Poppe added that altcoins were also on the radar and that it would be interesting to see how Ether (ETH) in particular deals with upcoming resistance.

    The top ten cryptocurrencies by market cap showed clear copycat strength on daily timeframes, led by ETH/USD which matched Bitcoin’s 5% gains.

    Cardano (ADA), while dropping several percentage points on the day, was still up 35% compared to the same time last week, making it the top-ten’s best performer.
