  • Peer Co-Movement in Crypto Markets
    Peer Co-Movement in Crypto Markets G. Schwenkler and H. Zheng∗ February 4, 2021y Abstract We show that peer linkages induce significant price co-movement in crypto markets in excess of common risk factors and correlated demand shocks. When large abnormal return shocks hit one crypto, its peers experience unusually large abnormal returns of the opposite sign. These effects are primarily concentrated among smaller peers and revert after several weeks, resulting in predictable returns. We develop trading strategies that exploit this rever- sal, and show that they are profitable even after accounting for trading fees and frictions. We establish our results by identifying crypto peers through co-mentions in online news using novel natural language processing technologies. Keywords: Cryptocurrencies, peers, co-movement, competition, natural language pro- cessing. JEL codes: G12, G14, C82. ∗Schwenkler is at the Department of Finance, Santa Clara University Leavey School of Business.

  • Ethereum Introduction
    Cryptocurrencies & Security on the Blockchain Ethereum Introduction Prof. Tom Austin San José State University Some Brief Ethereum Facts • Number 2 cryptocurrency by market cap. – Not why we are studying it • Core developers – Vitalik Buterin (creator) – Gavin Wood • Block 0 mined July 30, 2015 Ethereum Prehistory: Mastercoin • Protocol layer on top of Bitcoin • Focused on financial contracts – Two-party contracts with enforced terms • October 2013: Vitalik suggested a more flexible scripting language – More limited vision – Not Turing-complete December 2013: Ethereum Proposal • The name "Ethereum" first appears in print • Transaction fees for different actions included – Computational steps paid for in ether (this concept changed later) – Once fees exhausted, processing stops • Contracts became accounts in their own right More History • Gavin Wood joins project – Designs the Ethereum Virtual Machine (EVM). – Writes "The Yellow Paper" in 2014. • Gas model changes – Miners explicitly vote on gas price. – Previous approaches allowed them to implicitly do this anyway. Account Types • Externally owned accounts (EOAs) – Equivalent to accounts in Bitcoin – Have a private key • Contract accounts – Have contract code – No private key • Cannot initiate transactions – Can react to transactions and call other contracts – Contain data Common Features with Bitcoin • Digital currency – Called ether (ETH) • Not "ethereum" – Smallest unit: wei • Proof-of-work blockchain – Ethash – designed to be ASIC-resistant – Much quicker: 14-15 second block time – Plans to move to proof-of-stake (Casper) • Peer-to-peer network Differences from Bitcoin • Turing-complete virtual machine – Almost… – Brings up a lot of security issues • Gas – Prevents denial-of-service attacks – Transactions specify • ETH earmarked for gas • gas-rate • Less conservative development culture – "Move fast and break things" – More frequent hard-forks – Expect changes Lab, Part 1 Create Ethereum MetaMask wallet.
