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.

The number of cryptocurrencies has increased from about 2,000, with a market capitalization of over $200 billion in late 2017, to over 8,000, with a market capitalization of about $1.6 trillion. For context, the market capitalization of global equities is about $110 trillion, that of the S&P 500 stocks is $35 trillion and that of US Treasuries is $22 trillion. Reported trading volume in cryptocurrencies, as represented by the two largest cryptocurrencies by market capitalization, has increased sixfold, from an estimated $6.8 billion per day in late 2017 to $48.6 billion per day in May 2021.1 This data is based on what is called “clean data” from Coin Metrics; the total reported trading volume is significantly higher, but much of it is artificially inflated.2,3 For context, trading volume on US equity exchanges doubled over the same period. -

It is currently highly challenging to fix er- rors and deploy a patched contract in time. Instant patching is Recently, the blockchain community has witnessed several especially important since smart contracts are always online incidents due smart contract errors [7, 39]. One especially due to the distributed nature of blockchain systems. They also infamous incident is the “TheDAO” reentrancy attack, which manage considerable amounts of assets, which are at risk and resulted in a loss of over 50 million US Dollars worth of often beyond recovery after an attack. Existing solutions to Ether [31]. This led to a highly debated hard-fork of the upgrade smart contracts depend on manual and error-prone pro- Ethereum blockchain. Several proposals demonstrated how to defend against reentrancy vulnerabilities either by means of cesses. This paper presents a framework, called EVMPATCH, to instantly and automatically patch faulty smart contracts. offline analysis at development time or by performing run-time validation [16, 23, 32, 42].

State of the Art: the Monero Cryptocurrency Mining Malware Detection Using Supervised Machine Learning Algorithms
International Journal of Applied Science and Engineering State of the art: The monero cryptocurrency mining malware detection using supervised machine learning algorithms Wilfridus Bambang Triadi Handaya1*, Mohd Najwadi Yusoff 2, Aman Jantan2 1 Department of Informatics, Universitas Atma Jaya Yogyakarta, Daerah Istimewa Yogyakarta, Indonesia 2 School of Computer Sciences, Universiti Sains Malaysia, Penang, Malaysia ABSTRACT Today’s evolving information technology trend is fuelling increasingly various cybercrime. Various cybercrime types, such as malware attacks and data breach activities, organizations, and countries, occur every day. Malware is one of the biggest cyber threats on the Internet today. Every year, the number of data breaches continues to increase. Mining is a complete cryptocurrency network’s computing process to verify transaction records, called blockchains, and receive digital coins in return. This mining process requires severe hardware and significant CPU resources to create cryptocurrencies. A statistic published by Statista in mid-2020 about the most detected crypto-mining malware types influencing corporate networks global from January to June 2020, it can be seen that cryptocurrency mining activity leading to the pool of Monero amounts to 46% derived from the use of XMRig. Malware detection is like an endless war between malware authors and malware prevention vendors. This trend change also makes the procedures and forms of analysis must adapt. From previously done manually with various tools for static analysis, to be OPEN ACCESS subsequently replaced with automatic analysis through the application of machine learning algorithms.

Coinbase Explores Crypto ETF (9/6) Coinbase Spoke to Asset Manager Blackrock About Creating a Crypto ETF, Business Insider Reports
Crypto Week in Review (9/1-9/7) Goldman Sachs CFO Denies Crypto Strategy Shift (9/6) GS CFO Marty Chavez addressed claims from an unsubstantiated report earlier this week that the firm may be delaying previous plans to open a crypto trading desk, calling the report “fake news”. Coinbase Explores Crypto ETF (9/6) Coinbase spoke to asset manager BlackRock about creating a crypto ETF, Business Insider reports. While the current status of the discussions is unclear, BlackRock is said to have “no interest in being a crypto fund issuer,” and SEC approval in the near term remains uncertain. Looking ahead, the Wednesday confirmation of Trump nominee Elad Roisman has the potential to tip the scales towards a more favorable cryptoasset approach. Twitter CEO Comments on Blockchain (9/5) Twitter CEO Jack Dorsey, speaking in a congressional hearing, indicated that blockchain technology could prove useful for “distributed trust and distributed enforcement.” The platform, given its struggles with how best to address fraud, harassment, and other misuse, could be a prime testing ground for decentralized identity solutions. Ripio Facilitates Peer-to-Peer Loans (9/5) Ripio began to facilitate blockchain powered peer-to-peer loans, available to wallet users in Argentina, Mexico, and Brazil. The loans, which utilize the Ripple Credit Network (RCN) token, are funded in RCN and dispensed to users in fiat through a network of local partners. Since all details of the loan and payments are recorded on the Ethereum blockchain, the solution could contribute to wider access to credit for the unbanked. IBM’s Payment Protocol Out of Beta (9/4) Blockchain World Wire, a global blockchain based payments network by IBM, is out of beta, CoinDesk reports.
