1. The blockchain is a ledger that keeps track of how much ‘stuff’ (ie BTC, ETH,…create your own currency if you wish) you have. Its the history of transactions. ‘Ethereum’ provides a platform for building contracts…if a contract’s conditions are met, then a transaction (whose rules and automation are agreed ahead of time) automatically occurs and the result of that transaction becomes a part of the ledger. Anyone will be able to see that an address (sellers’ public key) has given ‘stuff’ to another address (purchasers’ public key).

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. By providing developers with the tools to build decentralized applications, Ethereum is making all of this possible.

So the app is pretty great when it comes to buying crypto, they can give you the funds immediately at the current price of the crypto, so high purchasing fees and selling it on a quick time line are virtually non existent when you are making small orders, most likely biggers as well. Not so fast... if you purchased it through your bank, because the allowance is higher on it than 25$ for a new card, your funds are basically frozen for 2 weeks. You can not cash out, nor you can send crypto to another wallet, so if you are looking for something to transaction with this isn’t the greatest app to do it with. I’m stuck with funds frozen for already 10 days, and now I have to wait another 5 for the banks to clear it, when on the card is faster, but you are stuck with the same high cost for selling it which comes out to bite you in the but for the fees. Yes, I can sell it and wait at usd wallet so the price doesn’t fluctuate, but again, if you want to get the funds out they are the power delay and have no intention to speed the process and again, you are in lala land waiting for it! Before, it’s not used be this bad but seems like delays and restrictions will expand. For the high cost of buying, and buying always at a higher price than it actually is, it makes even more worthless, even waisting time and resources just on trying to obtain some btc. There are better apps and cheaper apps that don’t cause you such issues. Good luck crypto fans

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.

In the case of Bitcoin, miners run computer programs to verify the data that creates a complete transaction history of all Bitcoin. A technology known as the blockchain, which is used to create irreversible and traceable transactions, makes the process of verification possible. Once a miner has verified the data (which comes in a block, hence, blockchain), they are rewarded with some amount of digital currency, the same currency for which they were verifying the transaction history. So mining Bitcoin, for example, would earn you Bitcoin.

Ethereum was announced at the North American Bitcoin Conference in Miami, in January, 2014.[9] During the same time as the conference, a group of people rented a house in Miami: Gavin Wood, Charles Hoskinson, and Anthony Di Iorio, a Torontonian who financed the project.[9] Di Iorio invited friend Joseph Lubin, who invited reporter Morgen Peck, to bear witness.[9] Six months later the founders met again in a house in Zug, Switzerland, where Buterin told the founders that the project would proceed as a non-profit. Hoskinson left the project at that time.[9]

Ethereum's smart contracts are based on different computer languages, which developers use to program their own functionalities. Smart contracts are high-level programming abstractions that are compiled down to EVM bytecode and deployed to the Ethereum blockchain for execution. They can be written in Solidity (a language library with similarities to C and JavaScript), Serpent (similar to Python, but deprecated), LLL (a low-level Lisp-like language), and Mutan (Go-based, but deprecated). There is also a research-oriented language under development called Vyper (a strongly-typed Python-derived decidable language).

don’t use coinbase. They held my funds and I couldn’t use my bitcoins until their value dropped by 1/4. this company is awful. I verified my ID, bank account, email, and everything and they lied and said initially it takes 3-4 days for funds to be available. once the bought the bitcoin they said it will take one week. and that is still a lie because after one week the funds are NOT available. liars !!!!

On February 16, 2018, Coinbase admitted that some customers were overcharged in error for credit and debit purchases of cryptocurrencies. The problem was initiated when banks and card issuers changed the merchant category code (MCC) for cryptocurrency purchases earlier this month. This meant that cryptocurrency payments would now be processed as "cash advances", meaning that banks and credit card issuers could begin charging customers cash-advance fees for cryptocurrency purchases. Any customers who purchased cryptocurrency on their exchange between January 22 and February 11, 2018 could have been affected. At first, Visa blamed Coinbase, telling the Financial Times on February 16 that it had "not made any systems changes that would result in the duplicate transactions cardholders are reporting." However, the latest statement from Visa and Worldpay on the Coinbase blog clarifies: "This issue was not caused by Coinbase."[45]

Coinbase is not just a “wallet” for digital money, it is an entire platform that makes it is possible to store, transfer, buy and sell it. The process of signing up is similar to any other website. After logging in, it is possible to choose any national currency in the settings to show the relative rate of Bitcoin. In order to transfer money, it is necessary to add some to the account and then submit the information about the receiver. The latest news concerning Coinbase is that access to its system is now available for 24 countries. Coinbase offers two-factor authentication, exchange on stock markets where all operations are possible without leaving the account, instant confirmation of transfers, and partnership programs which gives users $10 for inviting friends to join the platform.

Like Bitcoin, Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability. Bitcoin offers one particular application of blockchain technology, a peer to peer electronic cash system that enables online Bitcoin payments. While the Bitcoin blockchain is used to track ownership of digital currency (bitcoins), the Ethereum blockchain focuses on running the programming code of any decentralized application.

Coinbase has lost my money twice now. Once was due to an old account that, thanks to a bug in their verification process, I cannot re-authenticate. I bought 1 bitcoin back when they were only about $50 each with Coinbase. That money is gone forever now. And I acknowledge that it’s my fault that I did not set up a forwarding email with Coinbase, their support just refused to help. The second time was a month ago. I made a trade on Coinbase, and for some reason, the app glitched to think I have 5x more money than I actually… Read more »

Ethereum is an open source, public, blockchain-based distributed computing platform and operating system featuring smart contract (scripting) functionality. It supports a modified version of Nakamoto consensus via transaction-based state transitions. Ether is a cryptocurrency generated by the Ethereum platform and used to compensate mining nodes for computations performed.[3] Each Ethereum account has an ether balance and ether may be transferred from one account to another.

While another less aggressive soft fork solution was put forth, the Ethereum community and its founders were placed in a perilous position. If they didn’t retrieve the stolen investor money, confidence in Ethereum could be lost. On the other hand, recovering investor money required actions that went against the core ideas of decentralization and set a dangerous precedent.

There is ongoing research on how to use formal verification to express and prove non-trivial properties. A Microsoft Research report noted that writing solid smart contracts can be extremely difficult in practice, using The DAO hack to illustrate this problem. The report discussed tools that Microsoft had developed for verifying contracts, and noted that a large-scale analysis of published contracts is likely to uncover widespread vulnerabilities. The report also stated that it is possible to verify the equivalence of a Solidity program and the EVM code.[41]

In the end, the majority of the Ethereum community voted to perform a hard fork, and retrieve The DAO investors money. But not everyone agreed with this course of action. This resulted in a split where two parallel blockchains now exist. For those members who strongly disagree with any changes to the blockchain even when hacking occurs there is Ethereum classic. For the majority who agreed to rewrite a small part of the blockchain and return the stolen money to their owners, there is Ethereum.

Ether is a cryptocurrency generated by the Ethereum platform and used to compensate mining nodes for computations performed.[3] Each Ethereum account has an ether balance and ether may be transferred from one account to another.
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]

Cryptocurrencies are experiencing a moment of unprecedented attention and speculation for several reasons. 1) The value of Bitcoin has been steadily climbing through 2017, with Ether seemingly poised to overtake the cryptocurrency giant any day; 2) Blockchain technology has purposes above and beyond cryptocurrency, and has been hailed by some as the backbone of the future financial system; 3) The increasing number of people who see cryptocurrency as a form of investment similar to gold. If cryptocurrencies stabilize in value, buying Bitcoin or Ether has the potential to be a worthy venture.
