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].

Article Friis Glaser
International Journal of Community Currency Research 2018 VOLUME 22 (SUMMER) EXTENDING BLOCKCHAIN TECHNOLOGY TO HOST CUSTOMIZA- BLE AND INTEROPERABLE COMMUNITY CURRENCIES Gustav R.B. Friis* and Florian Glaser** * Brainbot Technologies AG, Mainz ** Karlsruhe Institute of Technology (KIT), Karlsruhe ABSTRACT The goal of this paper is to propose an open platform for secure and interoperable virtual community currencies. We follow the established information systems design-science approach to develop a prototype that aims to combine best practices for building mutual-credit community currencies with the unique features of blockchain technology. The result is a specification of an open Internet platform that enables users to join and to host customized community currencies. The hosted currencies can be classified as credit-based future type of money with decentralized issuance. Furthermore, we describe how the transparency, security and interoperability properties of blockchain technology offer a solution to the inherent problems of existing, centrally operated community currency software. The characteristics of the prototype and its ability to fulfil the design-objectives are examined by a relative evaluation against existing payment and currency systems like Bitcoin, LETS and M-Pesa.
