Blockchain vs. Database: Understanding the Differences
Like the internet, blockchain technology has also taken the world by storm. It has become a part of our daily lives. Though still in a state of infancy, it has open avenues for newer technological advancements to develop.
Two of the most commonly associated words with blockchain innovation are databases and blockchain. Many users often use these terms synonymously but there are differences between the two.
For starters, databases run on client-server networks. Blockchain, on the other hand, follows a peer-to-peer network. Their entities also have different cores. In this article, we shall learn about the distinction between these two so that you can make an informed decision when choosing one.
Centralized vs. Decentralized Control
Blockchain follows a decentralized system architecture. This means that if two clients trust each other and wish to share some sensitive piece of information amongst themselves, there is no need for a third-party operator between them. The can easily share information without one. This is possible because of all blockchain transactions process by nodes that act as middlemen. They ensure that each user produces a similar common system of record. This eliminates the need for a centralized control system.
Nevertheless, databases are highly centralized systems. This means that there is involvement of a third-party. The users have to trust the administrator to handle the transactions. It is also in the hands of the administration to allow or restrict you to read and write any saved data on the database. The output is great and maintenance is also very simple.
Efficiency
Whereas blockchain provides an ideal transaction platform, it is a bit sluggish in terms of speed than most digital platforms like PayPal or Visa. Its developers are continuously looking for means to improve its efficiency but despite their efforts, the users still have to deal with a slower platform. This happens because every node that processes a transaction does it individually. It then compares the results with other nodes. This requires time and therefore results in a slower transaction speed.
In contrast, databases have been up and running for years now. They too, started slow, but with time and innovation, their speed and performance improved. Most databases still use Moore’s law to augment the efficiency and performance of conventional databases.
Confidentiality
Ever thought why blockchain rose to such heights in such a short period of time? Well, it all comes down to the confidentiality it offers. Bitcoin is read-uncontrolled and writes uncontrolled. This means that any user can write a new block in the chain and also check one out of the chain when needed.
This isn’t the case with a central database. A database is read-controlled and write-controlled. There is an administrator appointed to keep this in check. As per the network’s protocol, only a few selected individuals can read and write into the database.
However, if the primary goal isn’t to trust but privacy, database offers similar benefits like blockchain.
Final Word
You may have noticed that each of the systems has some basic pros and cons. It is difficult to identify which of the two is a better option since users may have specific needs. Now that you have identified the differences between the two, it is up to you to make a well-informed decision.
AdvCash Review
Short for Advance Cash, AdvCash is a Belize-based firm which issues Bitcoin debit cards. The parent company behind the AdvCash is Wave Crest Holdings Limited –a well-renowned name in the cryptocurrency market. You will be surprised to know that the company helped many debit card issuers to partner with Visa but it itself uses MasterCard to issue its debit card. This saved the company and its users from facing any issues when Visa ceased partnership with other debit card issuers. The decision to opt for MasterCard was only because the company’s primary target audience is digital nomads and freelancer. It wanted to create an easy market for them to penetrate into the cryptocurrency market with ease and also to pay cheaper fees.
In this article, we shall review some of the advantages, disadvantages and fee structures of the AdvCash Bitcoin debit card.

Final Word
The debit card doesn’t enjoy a positive review on platforms like TrustPilot. However, the management is fast to respond to any customer-related query and ensures all the demands are addressed with satisfaction. Despite this, it hasn’t stopped the bad review from popping up every now and then which calls for suspicion. On the whole, it seems to be a fairly good choice for European and Russians users. If only the company would invest in its distribution channels, the card has the potential to reach amongst the top debit cards. There is news that the company is currently testing its mobile app, which is a good sign. With no monthly charges, low ATM withdrawal rates, and strict security, the card does have the potential to win more customers.
Litecoin Vs Bitcoin: What’s The Difference?
Contrary to misconceptions, Litecoin cryptocurrency is not the first fork of Bitcoin. Those were the digital asset and the Namecoin payment system of the same name. Although this did not prevent Litecoin from winning the title of virtual silver. It is safe to say that 2011 was a turning point in the formation of alternative monetary units. After all, it was then that the beginning of the emergence of a significant number of digital assets based on Bitcoin open source, and after altcoins, the mining of which uses an algorithm that differs from the standard generation process developed by Satoshi Nakamoto (the creator of the first cryptocurrency).
The evolution of crypto active assets is based on the principle of natural competition. The value of altcoins is determined by different features, so the question is: what is better – Bitcoin or Litecoin, does not lose its relevance today. Although, virtual silver from the day of its foundation settled in the TOP-list of digital currency units and continues to hold positions. Moreover, with each drop in Bitcoin quotes, one can hear statements that Litecoin has every chance of becoming a worthy alternative to the first cryptocurrency.
Litecoin and Bitcoin Market Capitalization
Determining which is more profitable, Bitcoin or Litecoin, and taking only the indicators of market capitalization and the dominance index as a basis, we can conclude that Bitcoin is the undisputed leader of the world of cryptocurrencies. At the time of writing (December 24, 2017), the total value of the first digital asset is $ 241 billion. He surpasses the competitor, who settled in the fifth position, more than 16 times. The dominance index, however, varies from 43–44%. The fact that the Bitcoin rate is about $ 13,000 is impressive. This figure is not maximum and has undergone an adjustment after a record retracement of the mark of $ 20,000, but about 55 times higher than the market value of Litecoin ($ 250). It is difficult to understand why the first digital asset should not be a segment leader? After all, he has always been significantly ahead of and ahead of his many competitors in these indicators.
The speed and profitability of transfers Bitcoin and Litecoin
Bitcoin significantly loses its competitor in terms of the speed of remittances. The growth in the number and volume of transactions in the network of the first cryptocurrency caused the emergence of problems with scaling. As a result, it is often possible to see that the number of unconfirmed transfers amounts to hundreds of thousands. The throughput rate often drops to a critical point.
Litecoin many people mistakenly perceive as a test version of Bitcoin. In fact, it is a separate player in the market. This error can be partially explained by the fact that the SegWit algorithm was activated here much earlier. Due to this, so high speed of passing payments increased by 2 times. Moreover, the Institute of atomic swaps was successfully integrated, which allows replacing Bitcoin when performing mutual settlements in the remote mode.
What do we see on the Bitcoin network? Despite the introduction of the Lightning Network (processing of micro-transactions outside the main chain of the blockchain) and SegWit, the early likelihood of launching SegWit2X, the issue of fast transfer operations remains unresolved. However, these details do not give an answer to the question: what is better, Bitcoin or Litecoin? It is known that the services offered by third-party services allow making transfers using Bitcoin coins very quickly, without waiting for the standard 6 confirmations from miners. In addition, you can acquire debit Bitcoin cards to operate your crypto savings without any restrictions.
When trading or dealing with cryptocurrency, users need a wallet to hold their Ether tokens. There are various cryptocurrency wallet types for Ether token storage –5 of which we shall review in this article below. But before we do, let us first understand how Ethereum wallets work.
How do Ethereum Wallets work?
Ethereum wallets are different from regular wallets. These store private keys instead of Ether tokens. The private keys allow access to Ether tokens recorded on Ethereum blockchain. If the user misplaces/loses the wallet and private keys, then all ether tokens are also lost. This is why it is essential to take all the necessary steps to ensure their safety and opt for the most suitable wallet for your Ether tokens.
Receiving Ether Tokens on Ethereum Wallets
Confused as to how Ethereum wallets receive the Ether tokens? Well, in addition to private keys, each wallet also has a public key. This is obtainable by anyone. It is mainly the address users use to send and receive cash. The public key allows all users to track your transaction history as well as check your current balance. However, it can’t give anyone access to your private information or allow them to withdraw any cash from your ether wallet.
Types of Ethereum Wallets
- Online wallet
- Desktop wallets
- Mobile wallets
- Paper wallets
- Hardware wallets
Third-party Wallets and Private Wallets
All Ethereum debit cards come attached to an online wallet. This is a third-party type wallet which is tied to a debit card site or exchange firm.
On the other hand, private wallets come in various types such as desktop, mobile, paper or hardware wallets. They are entirely the user’s personal wallet and don’t share any third-party intervention from an exchange or debit card site. Let’s take a brief look at their working below.
Desktop wallets
Desktop wallets are applications installed on a desktop computer. Although safe in general, there is always the risk of the computer breaking down, leaving the user helpless at recuperating the files. This also means you will lose your Ether tokens. Atomic Wallet is a kind of desktop wallet.
Mobile wallets
Like desktop wallets, mobile wallets are installable applications on a phone. There are multiple Ethereum wallet apps on iOS, the App Store or Google Play. Once installed, these apps convert the phone into an Ethereum wallet. There are also some apps that offer wallet synchronization with other devices but not all. If the user loses the phone and the wallet isn’t synchronized to any other device, this means all the Ether tokens will be lost.
Paper Wallets
A paper wallet is the most basic kind of Ethereum wallet. Even though it is labelled as a paper wallet, it can be any lifeless thing you draw your private key onto. Papers wallets eliminate the dangers of technical issues. They can also take the private key offline when required. The only drawback of paper wallets is that they can be misplaced, stone or lost.
Hardware Wallets
Hardware wallets are most preferable for those who wish to safeguard themselves from any third-party, desktop or mobile wallet threats and scams. This is one reason why many call it a sensible investment. As the name suggests, a hardware wallet is a device which holds your private keys –a lot like a flash drive. Another perk is that hardware wallets allow users to go offline whenever needed. This also limits the chances of hacking and loss of data. Ledger Nano S is an example.
Full node Wallet
These wallets are also desktop wallets containing all the data from the Ethereum Blockchain. To use a full node wallet, the user needs to download copious GB of data. Once the installation is complete, the desktop becomes an active node that validates Ethereum blockchain transactions. In case you wish not to download the fill node wallet, then you will have to partner with some other node without the whole blockchain.
Hot vs. cold wallets
Hot and cold wallets are technical terms for online and offline wallets. Many users prefer hot/online wallets due to their easy access. However, this case also comes with a price. Hot wallets are most prone to scams and hacks. Conversely, cold wallets are more secure in nature but less effective.
