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.

The Magnificent Seven
The Magnificent Seven A closer look at functional attributes of blockchain platforms The Magnificent Seven1 Following a whitepaper published in late 2008, the Bitcoin system came into being in 2009, and the underlying technology became what we refer to as Blockchain today. 1 The top seven cryptocurrencies covered a good variety of attributes that are essential to gain a more thorough understanding of the potentials offered by this new technology. The Magnificent Seven 1 Since then, a variety of different cryptocurrency platforms have been created, and based on data from CoinMarketCap (https://coinmarketcap.com/), as of 27 March 2021, there were 8,964 crypto tokens in existence, with a total Market Cap of over USD$1.6 Trillion. The top seven cryptocurrencies made up around 80% of the global market capitalisation: Market Cap Token Symbol (billion USD) % Bitcoin BTC 1,026.8 59.23 Ethereum ETH 0,196.2 11.32 Cardano ADA 0,040.2 02.32 Binance Coin BNB 0,039.1 02.25 Tether USDT 0,038.5 02.22 Polkadot DOT 0,030.4 01.75 XRP XRP 0,025.8 01.49 80.58 Rest of 8,957 tokens 19.42 Bitcoin alone represents nearly 60% of the total cryptocurrency value, with Ethereum being the second highest by value. However, these cryptocurrencies are not in fact the same: value aside, they differ in some interesting ways, which in turn affect their “function” and value proposition.

Abstract: Cryptocurrencies are currently traded worldwide, with hundreds of different currencies in existence and even more on the way. This study implements some statistical and machine learning approaches for cryptocurrency investments. First, we implement GJR-GARCH over the GARCH model to estimate the volatility of ten popular cryptocurrencies based on market capitalization: Bitcoin, Bitcoin Cash, Bitcoin SV, Chainlink, EOS, Ethereum, Litecoin, TETHER, Tezos, and XRP. Then, we use Monte Carlo simulations to generate the conditional variance of the cryptocurrencies using the GJR-GARCH model, and calculate the value at risk (VaR) of the simulations. We also estimate the tail-risk using VaR backtesting. Finally, we use an artificial neural network (ANN) for predicting the prices of the ten cryptocurrencies. The graphical analysis and mean square errors (MSEs) from the ANN models confirmed that the predicted prices are close to the market prices. For some cryptocurrencies, the ANN models perform better than traditional ARIMA models.

Moreover, the chain could double-spend transactions, meaning they commit an attacker of the Tezos protocol knows in advance when an at- a transaction to the chain, receive some goods in exchange, and tack opportunity will arise, and can use this knowledge to arrange then delete the transaction, effectively robbing their counterparty. transactions to double-spend. We show that in particular cases, the Nakamoto [15] demonstrated that, in a Proof-of-Work (PoW) setting, Tezos protocol can be adjusted to protect against deep reorgs. -
Governance in Decentralized Networks
Governance in decentralized networks Risto Karjalainen* May 21, 2020 Abstract. Effective, legitimate and transparent governance is paramount for the long-term viability of decentralized networks. If the aim is to design such a governance model, it is useful to be aware of the history of decision making paradigms and the relevant previous research. Towards such ends, this paper is a survey of different governance models, the thinking behind such models, and new tools and structures which are made possible by decentralized blockchain technology. Governance mechanisms in the wider civil society are reviewed, including structures and processes in private and non-profit governance, open-source development, and self-managed organisations. The alternative ways to aggregate preferences, resolve conflicts, and manage resources in the decentralized space are explored, including the possibility of encoding governance rules as automatically executed computer programs where humans or other entities interact via a protocol. Keywords: Blockchain technology, decentralization, decentralized autonomous organizations, distributed ledger technology, governance, peer-to-peer networks, smart contracts. 1. Introduction This paper is a survey of governance models in decentralized networks, and specifically in networks which make use of blockchain technology. There are good reasons why governance in decentralized networks is a topic of considerable interest at present. Some of these reasons are ideological. We live in an era where detailed information about private individuals is being collected and traded, in many cases without the knowledge or consent of the individuals involved. Decentralized technology is seen as a tool which can help protect people against invasions of privacy. Decentralization can also be viewed as a reaction against the overreach by state and industry. -

At that time Bitcoin reached its all-time high of 20,000 and so did Ethereum ETH which surpassed 1,000. 000 to reach 1; Tezos XTZ is priced at 2. In the unlikely event of a significant change for the worst, we expect the Bitcoin price to continue appreciating. ERC-721 started as a EIP draft written by dete and first came to life in the CryptoKitties project by Axiom Zen. ERC-721 A CLASS OF UNIQUE TOKENS.

A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets
Journal of Risk and Financial Management Review A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets Nikolaos A. Kyriazis Department of Economics, University of Thessaly, 38333 Volos, Greece; [email protected] Abstract: This study is an integrated survey of GARCH methodologies applications on 67 empirical papers that focus on cryptocurrencies. More sophisticated GARCH models are found to better explain the fluctuations in the volatility of cryptocurrencies. The main characteristics and the optimal approaches for modeling returns and volatility of cryptocurrencies are under scrutiny. Moreover, emphasis is placed on interconnectedness and hedging and/or diversifying abilities, measurement of profit-making and risk, efficiency and herding behavior. This leads to fruitful results and sheds light on a broad spectrum of aspects. In-depth analysis is provided of the speculative character of digital currencies and the possibility of improvement of the risk–return trade-off in investors’ portfolios. Overall, it is found that the inclusion of Bitcoin in portfolios with conventional assets could significantly improve the risk–return trade-off of investors’ decisions. Results on whether Bitcoin resembles gold are split. The same is true about whether Bitcoins volatility presents larger reactions to positive or negative shocks. Cryptocurrency markets are found not to be efficient. This study provides a roadmap for researchers and investors as well as authorities.
