Any services that are centralized can be decentralized using Ethereum. Think about all the intermediary services that exist across hundreds of different industries. From obvious services like loans provided by banks to intermediary services rarely thought about by most people like title registries, voting systems, regulatory compliance and much more.

Ethereum-based customized software and networks, independent from the public Ethereum chain, are being tested by enterprise software companies.[47] Interested parties include Microsoft, IBM, JPMorgan Chase,[33][48] Deloitte,[49] R3,[50] Innovate UK (cross-border payments prototype).[51] Barclays, UBS and Credit Suisse are experimenting with Ethereum.

Ethereum provides a decentralized virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes.[4] The virtual machine's instruction set, in contrast to others like Bitcoin Script, is thought to be Turing-complete. "Gas", an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.[4]

As with other cryptocurrencies, the validity of each ether is provided by a blockchain, which is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[30][31] By design, the blockchain is inherently resistant to modification of the data. It is an open, distributed ledger that records transactions between two parties efficiently and in a verifiable and permanent way.[32] Unlike Bitcoin, Ethereum operates using accounts and balances in a manner called state transitions. This does not rely upon unspent transaction outputs (UTXOs). State denotes the current balances of all accounts and extra data. State is not stored on the blockchain, it is stored in a separate Merkle Patricia tree. A cryptocurrency wallet stores the public and private "keys" or "addresses" which can be used to receive or spend ether. These can be generated through BIP 39 style mnemonics for a BIP 32 "HD Wallet". In Ethereum, this is unnecessary as it does not operate in a UTXO scheme. With the private key, it is possible to write in the blockchain, effectively making an ether transaction.

In 2018 Coinbase launched their independant mobile wallet for iOS and Android. The wallet stores the private keys on the user’s device and only they have access to the funds. This brings Coinbase full circle as it started out as a wallet, transitioned to an exchange only (claiming that they are not a wallet) and now they are offering wallet services again.

Welcome to the 34th Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of Constellation. This will be comprised of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. Constellation launched in 2017 with a private sale that raised $35.2mn in exchange for 756mn DAG – the utility token for the Constellation Network. This amounted to 18.9% of the original 4,000,000,000 DAG maximum supply; however, as a gesture of good will, the founders burned the 288mn tokens originally allocated to them, leaving the maximum supply at 3.71bn DAG. The team raised no further funds following this. DAG was created as an ERC-20 token for accessibility purposes, but, upon the launch of the Mainnet in October, these tokens will be swapped for the native Directed Acyclic Graph tokens; hence the ticker, DAG.
Ethereum can also be used to build Decentralized Autonomous Organizations (DAO). A DAO is fully autonomous, decentralized organization with no single leader. DAO’s are run by programming code, on a collection of smart contracts written on the Ethereum blockchain. The code is designed to replace the rules and structure of a traditional organization, eliminating the need for people and centralized control. A DAO is owned by everyone who purchases tokens, but instead of each token equating to equity shares & ownership, tokens act as contributions that give people voting rights.

Ethereum has recently created a new standard called the ERC721 token for tracking unique digital assets. One of the biggest use cases currently for such tokens is digital collectibles, as the infrastructure allows for people to prove ownership of scarce digital goods. Many games are currently being built using this technology, such as the overnight hit CryptoKitties, a game where you can collect and breed digital cats.

Ethereum addresses are composed of the prefix "0x", a common identifier for hexadecimal, concatenated with the rightmost 20 bytes of the Keccak-256 hash (big endian) of the ECDSA public key (the curve used is the so called secp256k1, the same as Bitcoin). In hexadecimal, 2 digits represents a byte, meaning addresses contain 40 hexadecimal digits. An example of an Ethereum address is 0xb794F5eA0ba39494cE839613fffBA74279579268. Contract addresses are in the same format, however they are determined by sender and creation transaction nonce.[34] User accounts are indistinguishable from contract accounts given only an address for each and no blockchain data. Any valid Keccak-256 hash put into the described format is valid, even if it does not correspond to an account with a private key or a contract. This is unlike Bitcoin, which uses base58check to ensure that addresses are properly typed.

J. P. Morgan Chase is developing JPM Coin on a permissioned-variant of Ethereum blockchain dubbed "Quorum".[52] It's designed to toe the line between private and public in the realm of shuffling derivatives and payments. The idea is to satisfy regulators who need seamless access to financial goings-on, while protecting the privacy of parties that don't wish to reveal their identities nor the details of their transactions to the general public.[53]

On May 7, 2019, Binance revealed that it had been the victim of a “large scale security breach” in which hackers had stolen 7,000 Bitcoin worth around U.S.$40 million at the time.[11] Binance CEO Changpeng Zhao said the hackers “used a variety of techniques, including phishing, viruses and other attacks” and structured their transaction “in a way that passed our existing security checks.”[12] Binance halted further withdrawals and deposits but allowed trading to continue. The site pledged to reimburse customers through its secure asset fund.

Welcome to the 32nd Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of ExchangeCoin. This will be comprised of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. ExchangeCoin was launched in November 2017 with an ICO that raised 650 BTC, equating to over $5,000,000 at the time. The token issued, EXCC, has a maximum supply of 32,003,133, with 4mn EXCC sold during the ICO. Further, the project also has a premine of 12.1mn EXCC, equating to 37.95% of the maximum supply (from which the 4mn was sold to the public in the token sale). The token itself operates on the Equihash algorithm, and underwent a hard fork in July 2018, after which the network migrated to a dual Proof-of-Work/Proof-of-Stake consensus mechanism, with 30% of block rewards rewarded to stakers and 70% to miners. The block reward is progressively diminishing, with the current reward at 24.5 EXCC per block, with 2.5-minute block times.

In Ethereum all smart contracts are stored publicly on every node of the blockchain, which has costs.[56] Being a blockchain means it is secure by design and is an example of a distributed computing system with high Byzantine fault tolerance. The downside is that performance issues arise in that every node is calculating all the smart contracts in real time, resulting in lower speeds.[56] As of January 2016, the Ethereum protocol could process about 25 transactions per second.[56] In comparison, the Visa payment platform processes 45,000 payments per second leading some to question the scalability of Ethereum.[57] On 19 December 2016, Ethereum exceeded one million transactions in a single day for the first time.[58]
In March 2018, Binance announced its intentions to open an office in Malta after stricter regulations in Japan and China.[5] In April 2018, Binance signed a Memorandum of Understanding (MoU) with the Government of Bermuda[6]. Months later, a similar memorandum was signed with the Malta Stock Exchange to develop a platform for trading security tokens[7]. In 2019, company announced Binance Jersey, an independent entity from its parent Binance.com exchange, with the aim to expand its European influence. Jersey based exchange offers fiat-to-cryptocurrency pairs, including the Euro and the British pound.[8]

Until relatively recently, building blockchain applications has required a complex background in coding, cryptography, mathematics as well as significant resources. But times have changed. Previously unimagined applications, from electronic voting & digitally recorded property assets to regulatory compliance & trading are now actively being developed and deployed faster than ever before.

Essentially, if you are interested in trading in digital currencies but don't want to get bogged down in the underlying technology, products like Coinbase are a way to begin a foray into a new form of currency speculation and investing. You do, however, lose some of the advantages of trading in a cryptocurrency and through the blockchain. On Coinbase, you have no pseudo anonymity—your name is attached to your Coinbase account and so is your bank account, so transaction history is relatively easy to track down. And if you're not working on the blockchain, there's not much you can do to ensure that the verification of your transaction history or your account is taking place on the blockchain. You are, instead, placing trust in the intermediary, in this case, Coinbase.

Izabella Kaminska, the editor of FT Alphaville, has pointed out that criminals are using Ethereum to run Ponzi schemes and other forms of investment fraud.[68] The article was based on a paper from the University of Cagliari, which placed the number of Ethereum smart contracts which facilitate Ponzi schemes at nearly 10% of 1384 smart contracts examined. However, it also estimated that only 0.05% of the transactions on the network were related to such contracts.[69]

As the industry continues to investigate blockchain platforms, it’s apparent that Ethereum is becoming a de facto leader. For example, a few days ago JPMorgan publicly open-sourced its Quorum platform, architected and developed around the Go Ethereum client by Jeff Wilcke and his team. Several other major banks are using Ethereum, and Microsoft is anchoring its Bletchley platform on it as the foundational blockchain element. Industry, both publicly and confidentially, continues to contribute to Ethereum and work with us and others to help our promising, toddler-age codebase reach maturity. Stay tuned for news on this front.
