The 5 Most Common Crypto User Issues and How to Prevent Them
 
Eth wallet addressEU will make Bitcoin traceable and ban anonymous crypto wallets in anti-money laundering drive
Ethereum is a decentralized , open-source blockchain with smart contract functionality. After Bitcoin , it is the largest cryptocurrency by market capitalization. Ethereum was invented in by programmer Vitalik Buterin. Additionally, many other cryptocurrencies operate as ERC tokens on top of the Ethereum blockchain and have utilized the platform for initial coin offerings. Ethereum has started implementing a series of upgrades called Ethereum 2. Ethereum was initially described in a white paper by Vitalik Buterin , [3] [11] a programmer and co-founder of Bitcoin Magazine , in late with a goal of building decentralized applications. Hoskinson left the project at that time. Ethereum has an unusually long list of founders. Development was funded by an online public crowdsale from July to August , with the participants buying the Ethereum value token Ether with another digital currency, Bitcoin. While there was early praise for the technical innovations of Ethereum, questions were also raised about its security and scalability. In January , Ethereum was the second largest cryptocurrency in terms of market capitalization , behind Bitcoin. Buterin chose the name Ethereum after browsing a list of elements from science fiction on Wikipedia. He stated, "I immediately realized that I liked it better than all of the other alternatives that I had seen; I suppose it was the fact that [it] sounded nice and it had the word ' ether ', referring to the hypothetical invisible medium that permeates the universe and allows light to travel. Several codenamed prototypes of Ethereum were developed by the Ethereum Foundation as part of their proof-of-concept series. The Olympic network provided users with a bug bounty of 25, Ether for stress testing the limits of the Ethereum blockchain. In July , "Frontier" marked the tentative experimental release of the Ethereum platform. After the Constantinople upgrade on 28 February , [28] there were two network upgrades made within a month late in the year: Istanbul on 8 December and Muir Glacier on 2 January There have been two network upgrades in The first was the "Berlin" upgrade, implemented on 14 April The mechanism causes a portion of the Ether paid in transaction fees each block to be destroyed rather than given to the miner, reducing the inflation rate of Ether and potentially resulting in periods of deflation. After the hard fork, Ethereum subsequently forked twice in the fourth quarter of to deal with other attacks. In March , various blockchain startups, research groups, and Fortune companies announced the creation of the Enterprise Ethereum Alliance EEA with 30 founding members. In March , Visa Inc. Open-source development is currently underway for a major upgrade to Ethereum known as Ethereum 2. The stated goal is to increase throughput by splitting up the workload into many blockchains running in parallel referred to as sharding and then having them all share a common consensus proof-of-stake blockchain, so that to maliciously tamper with any singular chain would require one to tamper with the common consensus, which would cost the attacker far more than they could ever gain from an attack. Ethereum 2. Ethereum is a permissionless, non-hierarchical network of computers nodes which build and come to consensus on an ever-growing series of "blocks", or batches of transactions, known as the blockchain. Each block contains an identifier of the block that it must immediately follow in the chain if it is to be considered valid. Whenever a node adds a block to its chain, it executes the transactions therein in their order, thereby altering the ETH balances and other storage values of Ethereum accounts. These balances and values, collectively known as the state, are maintained on the node's computer separately from the blockchain , in a Merkle tree. Each node communicates with a relatively small subset of the network, known as its peers. Whenever a node wishes to include a new transaction in the blockchain, it sends the transaction to its peers, who then send it to their peers, and so on. In this way, it propagates throughout the network. Certain nodes, called miners, maintain a list of all of these new transactions and use them to create new blocks, which they then send to the rest of the network. Whenever a node receives a block, it checks the validity of the block and of all of the transactions therein and, if valid, adds it to its blockchain and executes all of said transactions. As the network is non-hierarchical, a node may receive competing blocks, which may form competing chains. The network comes to consensus on the blockchain by following the "longest-chain rule", which states that the chain with the most blocks at any given time is the canonical chain. This rule achieves consensus because miners do not want to expend their computational work trying to add blocks to a chain that will be abandoned by the network. Ether ETH is the cryptocurrency generated by the Ethereum protocol as a reward to miners in a proof-of-work system for adding blocks to the blockchain. It is the only currency accepted in the payment of transaction fees, which also go to miners. The block reward together with the transaction fees provide the incentive to miners to keep the blockchain growing i. Therefore, ETH is fundamental to the operation of the network. Ether is listed on exchanges under the currency code ETH. The shift to Ethereum 2. There are two types of accounts on Ethereum: user accounts also known as externally-owned accounts and contracts. Both types have an ETH balance, may send ETH to any account, may call any public function of a contract or create a new contract, and are identified on the blockchain and in the state by their address. User accounts are the only type which may create transactions. For a transaction to be valid, it must be signed using the sending account's private key, a character hexadecimal string that should only be known to the account's owner. Importantly, this algorithm allows one to derive the signer's address from the signature without knowing the private key. Contracts are the only type of account which has associated code a set of functions and variable declarations and contract storage the values of the variables at any given time. A contract function may take arguments and may have return values. Within the body of a function, in addition to control flow statements, a contract's code may include instructions to: send ETH, read from and write to its storage, create temporary storage memory that dies at the end of the function, perform arithmetic and hashing operations, call its own functions, call public functions of other contracts, create new contracts, and query information about the current transaction or the blockchain. Ethereum addresses are composed of the prefix "0x", a common identifier for hexadecimal , concatenated with the rightmost 20 bytes of the Keccak hash of the ECDSA public key the curve used is the so-called secpk1. In hexadecimal, 2 digits represent a byte, meaning addresses contain 40 hexadecimal digits, e. Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce. It is a bit register stack that is sandboxed from the node's other files and processes to ensure that for a given pre-transaction state and transaction, every node produces the same post-transaction state, thereby enabling network consensus. Gas is a unit of account within the EVM used in the calculation of a transaction fee, which is the amount of ETH a transaction's sender must pay to the miner who includes the transaction in the blockchain. Each type of operation which may be performed by the EVM is hardcoded with a certain gas cost, which is intended to be roughly proportional to the amount of resources computation and storage a node must expend to perform that operation. When creating a transaction, the sender must specify a gas limit and gas price. The gas limit is the maximum amount of gas the sender is willing to use in the transaction, and the gas price is the amount of ETH the sender wishes to pay to the miner per unit of gas used. The higher the gas price , the more incentive a miner has to include the transaction in their block, and thus the quicker the transaction will be included in the blockchain. The sender buys the full amount of gas i. If at any point the transaction does not have enough gas to perform the next operation, the transaction is reverted but the sender still pays for the gas used. This fee mechanism is designed to mitigate transaction spam, prevent infinite loops during contract execution, and provide for a market-based allocation of network resources. Our governance is inherently social, people who are more connected in the community have more power, a kind of soft power. The difficulty bomb is an Ethereum protocol feature that causes the difficulty of mining a block to increase exponentially over time after a certain block is reached, with the intended purpose being to incentivize upgrades to the protocol and prevent miners from having too much control over upgrades. As the protocol is upgraded, the difficulty bomb is typically pushed further out in time. The protocol has included a difficulty bomb from the beginning, and the bomb has been pushed back several times. Bitcoin's primary use case is that it is a store of value and a digital currency. Ether can also be used as a digital currency and store of value, but the Ethereum network makes it also possible to create and run decentralized applications and smart contracts. Ethereum blocks are validated approximately every 12 seconds on Ethereum as opposed to approximately every 10 minutes on Bitcoin. Additionally, Bitcoin has a fixed supply of 21,, coins, whereas Ethereum has no supply cap. The EVM's instruction set is Turing-complete. Ethereum's smart contracts are written in high-level programming languages and then compiled down to EVM bytecode and deployed to the Ethereum blockchain. They can be written in Solidity a language library with similarities to C and JavaScript , Serpent similar to Python , but deprecated , Yul an intermediate language that can compile to various different backends — EVM 1. There was also [ when? One issue related to using smart contracts on a public blockchain is that bugs, including security holes, are visible to all but cannot be fixed quickly. 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. Ethereum also allows for the creation of unique and indivisible tokens, called non-fungible tokens NFTs. Decentralized finance DeFi is a use case of Ethereum. Ethereum-based software and networks, independent from the public Ethereum chain , are being tested by enterprise software companies. Ethereum-based permissioned blockchain variants are used and being investigated for various projects. In Ethereum, all smart contracts are stored publicly on every node of the blockchain, which has costs. Being a blockchain means it is secure by design [ clarification needed ] 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. As of January , the Ethereum protocol could process about 25 transactions per second. In comparison, the Visa payment platform processes 45, payments per second leading some to question the scalability of Ethereum. Ethereum engineers have been working on sharding the calculations, and the next step Ethereum 2 was presented at Ethereum's Devcon 3 in November Ethereum's blockchain uses Merkle trees , for security reasons, to improve scalability, and to optimize transaction hashing. The network has faced congestion problems, such as in in relation to Cryptokitties. From Wikipedia, the free encyclopedia. Open-source blockchain computing platform. On social governance.

Life is busy and full of information; it can be hard to pay attention to warnings when the danger is not happening directly to you right now. Read through these cautionary tales with a sense of urgency and respect, because sooner or later one of these situations can be relevant to you. How catastrophic or minor that event will be in your case depends in large part on your foresight. Allow us to present — absolutely free and accurate foresight, courtesy of MEW support! Contrary to the initial panicked reaction, this does not usually mean that assets are missing. Most of the time, it's a misunderstanding or interface issue. Prevention: If you want to be crystal clear on what's happening with your crypto assets at all times, you must understand that there are many different blockchain networks and hundreds of thousands of tokens. Wallets may not support every single token out there, or they may not show everything automatically. Before sending assets to a wallet, make sure you know that it supports your coins. Even when it does, sometimes you will need to tweak your interface setup. Solution: The first step when you don't see your assets in the wallet is heading to a blockchain explorer for an accurate view of your holdings. A wallet interface can have errors that prevent it from displaying balances correctly. This could be due to a variety of different reasons that may need further exploring on a case-by-case basis. In this case, you will need to change the network in the upper-right hand corner of MEW web interface. Also, keep in mind that every chain has its own block explorer — for example, BSC transactions and balances will show on BSCscan , and Polygon transactions and balances on Polygonscan. If you see transactions out of your wallet that you didn't make, your wallet keys must have been compromised and there is nothing that can be done except learning some important lessons for the future. Solution: Unfortunately, in these cases, nothing can be done — which is why prevention is so important! Prevention: Best and Thorough Security Practices!!! As wallet interfaces improve and the community becomes more engaged, instances of users reporting their assets were phished or hacked have gone down considerably. However, where there is money, there will always be people looking to steal it, and crypto is no exception. Sadly, most of the time there is nothing that can be done for lost assets. The Ethereum blockchain is maintained in a decentralized fashion, so that each user has complete control and sole anonymous access to their assets. This means that there is no way to reverse transactions, and we can't look up the IP address of a phisher or determine ownership of any wallet address. There is a multitude of ways that a wallet can get phished or hacked, but when it comes to non-custodial wallets like MEW, it's nearly always due to user error — albeit scammers can be extremely inventive and subtle. Crypto has not changed those rules. Again, the most important thing to remember — never ever give your private key or phrase to anyone, and don't use them directly online. Nothing can excuse you from staying attentive, skeptical, and vigilant, but hardware wallets relieve some of that burden by making you safer in your online blockchain interactions. For the best security in a mobile wallet, download MEW wallet app. It keeps your information secure within the smartphone's local storage, provides security comparable to a hardware wallet, and can be used together with MEW web for extended functionality. The only information you have to keep track of is your recovery phrase, which is meant for back-up and restoration purposes only keep it written down in a safe place and never share it. Losing assets is very hard and discouraging, and we are sorry to see anyone go through the experience. That's why we recommend reading our best tips on avoiding phishing right now! All transactions on the blockchain are final, and unfortunately assets can't be returned, but there are ways to prevent this from happening again. Solution: Nothing, unfortunately, unless you have incredible luck and chance upon an active wallet with an honest owner who will realize a mistake was made and send your assets back to you chances of this are astronomically low. Prevention: Transactions on the blockchain can't be frozen or reversed due to its decentralized and immutable properties. Assets sent to the wrong address are lost forever. This is an easy mistake to make, as each Ethereum address is 42 characters long and just one wrong letter results in a completely different, often unused wallet. One way of making this process much easier and more foolproof is through blockchain domains. In the meantime, the best line of defense against sending to wrong addresses is double and triple checking your transaction details before confirming. MEW wallet app makes sending easy by letting you scan a QR code of the destination address and keeping track of addresses you've used before. On MEW web , you can save addresses that you use frequently in your 'Contacts' list, and quickly select them from a dropdown on Send and Swap pages. You can also use our blockchain explorer EthVM to make a list of Favorite addresses, for quick access to copy and paste. An important detail: sending assets directly to a contract address like an address that was used to establish a token will usually result in the permanent loss of your assets. There are exceptions to this rule, such as with smart contract wallets and exchanges. Just make sure that if you are sending to a contract, you know for certain that's how it's supposed to be. If you can't seem to get your assets out of the wallet, it's not that MEW or Ethereum is 'down'. Usually, it's a matter of providing the right conditions or checking your assets on the blockchain. Prevention: Before interacting with Ethereum, keep in mind that all transactions require gas paid in ETH , while other blockchains like Binance Smart Chain or Polygon will have their own gas-paying coins. Also, remember that transactions between incompatible blockchains, like Ethereum and Bitcoin or Ethereum and Dogechain, are as yet impossible. Solution: The number one reason users cannot send their transactions boils down to one thing - gas. Gas is the fuel that makes all of Ethereum run and allows the creation of new blocks. You can check Eth Gas Station for the most up-to-date gas recommendations. Every action you make on the Ethereum blockchain is a transaction. Another reason transactions can stumble is incompatibility between blockchains. If an ERC20 token has forked or moved to mainnet launched its own coin on a completely separate blockchain , the new currency will not be compatible for sending and receiving on the Ethereum network. ERC20 tokens can only be sent to other Ethereum addresses which begin with 0x. Generally, big exchanges like Binance offer support for token swaps from ERC20 to mainnet coins. You must keep track of your own token investments to see if they are planning any transitions to a mainnet blockchain. There are many platforms for generating a crypto wallet and many different ways of doing it. If you don't check all your wallets on a regular basis, you can forget how you accessed the wallet, or the platform interface can change and confuse you. Prevention: When you create your wallet, be very careful to note all wallet information, including derivation path and public addresses used. Make sure you write down your seed or recovery phrase in a safe location and verify that the phrase is correct by resetting and restoring your wallet with that phrase before sending any assets to the wallet. Keep careful track of all various wallets created and check on them frequently. Solution: The 'lost wallet' issue takes many forms, depending on the method of access used. Let's start with hardware wallets: they are very secure and reliable, and they will always bring you back to the same generated addresses, as long as the seed phrase and the derivation path is correct. Some hardware wallets, like Ledger, take a different path than the standard. In the MEW interface, you can check your derivation path on the same screen where you choose the address to interact with. By clicking through different paths, you might see your familiar addresses. Using a passphrase will lead to a different set of addresses than those generated by the phrase alone. Usually, finding the correct derivation path and remembering whether a passphrase was added will resolve wrong addresses with hardware wallets. However, this is assuming that you can access the hardware wallet at all. Sometimes bugs or outdated firmware can cause your hardware wallet to stall or error out of the access screen. These can show up as separate addresses that you can switch between within the interface. If not, you can try restoring your MetaMask wallet with the 12 word phrase given when you created the wallet for the first time. The best practice for this is double checking your key. Keystore files require a password to unlock, and they always point to the same address. Keystore files are basically just encrypted private keys, so these two points of access are closely tied. You may get lucky! Then there is direct access by mnemonic phrases different from a hardware wallet or MEW wallet app in that there is no hardware device involved, just the phrase. Where you made the phrase is what determines if the password is necessary or not. Try excluding or including a password to see a different set of addresses. Reference the list of words used in mnemonic phrases for any possible spelling errors. You may also want to try entering your phrase words into the same interface you received them from hardware wallet, MEW wallet app, MetaMask , rather than putting them directly into the MEW interface which is not recommended in the first place. These 5 issues cover more than half of all MEW support inquiries! Preventing them does not require too much effort or cost — just some time to gain an understanding of how blockchain and wallets work. Trying to recover an old Ethereum wallet that you haven't accessed in a very long time? When network conditions and gas prices fluctuate, sometimes transactions can stay pending for a long time. Spoiler Alert : Every single one of these issues is preventable by the user I sent my assets to the wrong address All transactions on the blockchain are final, and unfortunately assets can't be returned, but there are ways to prevent this from happening again. So there you have it! More help with common issues Trying to recover an old Ethereum wallet that you haven't accessed in a very long time? The only way to move forward is by moving together. Writer, editor and educator focusing on disruptive technology and the way it changes society. Next Post. July 23, Buy, hold and swap Ether and tokens. Explore Ethereum with MEW.
