does the ethereum blockchain need to be synched to tranfer

The ethereum blockchain is the backbone of the entire crypto ecosystem. Regardless of which altcoins you may hold, chances are your wealth is stored on something that is connected to, or based on, the ethereum blockchain. So it is critical that you understand how the blockchain works and why it needs to be synched periodically.

What is the ethereum blockchain?

The ethereum blockchain is a public ledger that tracks the transactions and balances of users across the entire network. Every computer connected to the network has the ability to store and process transactions as they occur. When a transaction is processed by a participating node, the block is added to the chain. As a result, the entire network synchronizes and agrees on the most recent state of affairs.

The blockchain is secured through a system of incentivizing miners to secure the network. Miners are financially rewarded for performing this service and are compensated through the issuance of new tokens as a result of transactions conducted on the network. Miners can be any individual or group that obtains sufficient computational power to complete complex tasks, such as verifying transactions or maintaining the network’s consensus about which transactions should occur. Miners are responsible for securing the network, keeping track of the token supply, and preventing any attacks on the network. The fewer miners there are, the more at risk the network is of being targeted by sophisticated attackers, such as advanced nation-states with black-budget funds. If enough miners leave the network, it could be catastrophic to the whole crypto ecosystem. So it is in everyone’s best interest that the blockchain is maintained by as many miners as possible.

Why do I need to update the ethereum blockchain?

Updating the blockchain means performing a set of transactions that solve a particular computation problem. When this is accomplished, a brand new block will be chained to the end of the blockchain and all the nodes will update their copy of the ledger. This is similar to how databases are constantly updated by merchants and users after every purchase.

Updating the blockchain can take a significant amount of time, particularly if a large number of nodes need to be synchronized. This is why it is generally recommended to do this at least once every two weeks, to ensure that all the nodes contain the most up-to-date copy of the ledger. Failure to do this could lead to significant problems for the network. For example, if one of the nodes is controlled by a malicious actor, they could alter the blockchain to reflect an inflated token supply or even delete all the tokens, thus rendering all the cryptocurrencies in the network worthless.

What is the difference between the Ethereum Classic and Ethereum blockchains?

Ethereum classic is a blockchain that can be thought of as a simplified version of Ethereum. Instead of having a complex system of accounts and permissions, Ethereum classic only has two types of accounts: users and contract accounts. Users have the ability to transfer funds to contract accounts, which can subsequently be used by any party to conduct transactions on the blockchain.

Ethereum classic also uses the SHA-256 cryptographic hash function to secure the network instead of using the more complex and energy-intensive Proof-of-Work mechanism currently employed by the Ethereum blockchain. This makes Ethereum classic more affordable for smaller miners, who may not necessarily have the resources to invest in the expensive machinery needed to generate the heat and electricity to run a PC or dedicated cryptocurrency miner.

How can I update my ethereum wallet?

In addition to downloading the entire blockchain, you will need to ensure that your ethereum wallet is up-to-date and contains the latest version of the software. To do this, click on the Help button, then select Wallet update. You will then need to provide your wallet’s private key to download the most recent version of the software.

Why is the public ethereum blockchain open source?

The ethereum blockchain is entirely open source, which means that its source code is available to the public and anyone can theoretically replicate or improve it. This level of openness makes the blockchain more accessible to developers, entrepreneurs, and other interested parties. It also means that in case of a security breach, the entire blockchain could be inspected by anyone with the necessary knowledge and expertise to find the vulnerability. Finally, as we’ve already discussed, miners are incentivized through the issuance of new tokens to secure and maintain the network.

These benefits, however, come with the significant downside of making the blockchain more susceptible to malicious activity from outside sources. Just like any open source project, the public ethereum blockchain is also open to everyone for inspection and potentially malicious modification. But given the size and interconnectivity of the current blockchain, this downside is more theoretical than real. For the time being, the benefits of open source software generally outweigh the risks.

Why should I choose a hardware wallet instead of a software wallet?

The advantage of any hardware wallet, of course, is that it requires no software to operate and keep track of your cryptographic keys and coins. This makes it perfect for anyone that is not familiar with, or comfortable using, online wallets and the like. Furthermore, even if your wallet is stolen or lost, you can usually have your device physically replaced without too much hassle. Finally, hardware wallets are more secure than online wallets, since the information stored on the device itself is not easily accessible by any third party or hacker. Online wallets are extremely convenient, and many people only use them, because they are so much more ‘user-friendly‘ than storing your coins and private keys on a piece of hardware. But this convenience comes with the significant security risk of putting your sensitive data online, somewhere that can be accessed by any determined attacker.

Do I need to use a hardware wallet for all my cryptocurrencies?

That is a question only you can answer. Some experts, such as ShapeShift, claim that for every type of cryptocurrency, you need a separate wallet. While this may be true for major cryptocurrencies such as Bitcoin and Ethereum, it is almost certainly over-stated for smaller and more obscure coins or tokens.

For instance, Litecoin users do not need a hardware wallet to store their digital coins and keys. They can use any wallet program or service that they like, as long as they ensure that they keep their private key a secret. The same goes for Dogecoin, Vertcoin, Nxt, and the like. So if you are looking to store your coins in a hurry, and want to avoid using a complex piece of software that you may eventually forget about, then a hardware wallet may be your best option.
