Is Blockchain Safe To Use

Is Cryptocurrency Safeand How Can You Safely Invest

How Safe is Blockchain Really?

When someone asks if buying and selling cryptocurrency is safe, they may be asking one of two questions:

  • Is crypto a risky investment that could go down in value quickly?

  • Does crypto have security risks that could result in me losing money via a scam or other type of fraud?

Since these are fundamentally different questions, well address each of them individually.

Blockchain For Data Storage

There are a few ways that a Blockchain can be used in distributed storage software. One of the most common is to:

  • Break up data into chunks.
  • Encrypt the data so that you are the only one with access to it.
  • Distribute files across a network in a way that means all your files are available, even if part of the network is down.
  • Essentially, instead of handing your files to a company like Amazon or Microsoft, you distribute it across a network of people all over the world. The cloud is shared by the community, and nobody can read or tamper with anyone elses sensitive data. In other words, you stay in control. This could also be useful in public services to keep public records safe, available, and decentralized.

    Another model is to just save a cryptographic signature of a document or file on a Blockchain. This would give users a way to ensure a file is untampered, without needing to save the entire file on the Blockchain. When you look at a file, you can guarantee that it is the same version of the document that existed at another time.

    Smart contracts can also be used with Blockchains. These ensure that certain transactions happen when certain conditions are met, meaning records can be programmed to be changed or updated automatically.

    Data Security A Global Crisis

    Data is quickly becoming one of the most valuable resources in the world. The list of the top 10 companies by market capitalization is now dominated by data-centric companies like Facebook, Alphabet, Microsoft, Apple, and Amazon. That value means your data, especially your sensitive data, is now a prime target for cyber criminals, and you probably arent as protected as you think.

    Even giant companies like Anthem, Target Corp, and Home Depot have had major data breaches over the last few years affecting hundreds of millions of people. Clearly, current solutions arent good enough to keep us safe.

    Cloud services often arent the solution either. As hugely centralized systems, they are more valuable targets still. You also need to trust a 3rd party to store your sensitive data for you, which for many companies often isnt desirable or even legal. A new solution is needed.

    Very Poor Support Service

    Blockchain asked for 3 Document as compulsory, which I dont have all three, Passport, ID card and Driving license, I am too old to drive and I dont have passport, I only have an ID card. I think Blockchain just scammed me, and are playing a Charlie Charlie game to fool me. Blockchain is currently declining the ID card which they accepted at first and got me verified, so why ?Blockchains service is very poor when it comes to gold verification. They will seize your crypto in the name of holding your funds safe because of their so called custodial wallet . Do not use their custodial wallet, but you can use their . …after I had my gold level verification successful, I bought crypto and as a new user i forget my password and had to login with 12 word phrase, they deactivated my gold level verification and asked I should reverify, I had to reverify. It is 3 weeks now and I have not got verified for gold level again, I thought it was approximately 5 days for verification …blockchains verification team is really slow and poor in response, I lost my profit and some percentage of my initial crypto, because they have restricted me from withdrawing, swapping or selling to my account. I wont advice anyone to use the gold verified blockchain.

    How To Invest In Blockchain

    is the Wallet Safe?

    You cant actually invest in blockchain itself, since its merely a system for storing and processing transactions. However, you can invest in assets and companies using this technology.

    The easiest way is to purchase cryptocurrencies, like Bitcoin, Ethereum and other tokens that run on a blockchain, says Gray.Another option is to invest in blockchain companies using this technology. For example, Santander Bank is experimenting with blockchain-based financial products, and if you were interested in gaining exposure to blockchain technology in your portfolio, you might buy its stock.

    For a more diversified approach, you could buy into an exchange-traded fund that invests in blockchain assets and companies, like the Amplify Transformational Data Sharing ETF , which puts at least 80% of its assets in blockchain companies.

    A Blockchain Network Is Only As Secure As Its Infrastructure

    When establishing a private blockchain, you must decide the best platform for deployment. Even though blockchain has inherent properties that provide security, known vulnerabilities in your infrastructure can be manipulated by those with ill intent. Ideally, you should have an infrastructure with integrated security that can:

    • Prevent anyone even root users and administrators from accessing sensitive information
    • Deny illicit attempts to change data or applications within the network.
    • Carefully guard encryption keys using the highest-grade security standards so they can never be misappropriated.

    With these capabilities, your blockchain network will have the added protection it needs to prevent attacks from within and without.

    How Secure Is Blockchain Really

    The whole point of using a blockchain is to let peoplein particular, people who dont trust one anothershare valuable data in a secure, tamperproof way. Thats because blockchains store data using sophisticated math and innovative software rules that are extremely difficult for attackers to manipulate. But the security of even the best-designed blockchain systems can fail in places where the fancy math and software rules come into contact with humans, who are skilled cheaters, in the real world, where things can get messy.

    To understand why, start with what makes blockchains secure in principle. Bitcoin is a good example. In Bitcoins blockchain, the shared data is the history of every Bitcoin transaction ever made: an accounting ledger. The ledger is stored in multiple copies on a network of computers, called nodes. Each time someone submits a transaction to the ledger, the nodes check to make sure the transaction is validthat whoever spent a bitcoin had a bitcoin to spend. A subset of them compete to package valid transactions into blocks and add them to a chain of previous ones. The owners of these nodes are called miners. Miners who successfully add new blocks to the chain earn bitcoins as a reward.

    This story was part of our May 2018 issue

      What makes this system theoretically tamperproof is two things: a cryptographic fingerprint unique to each block, and a consensus protocol, the process by which the nodes in the network agree on a shared history.

      Is Blockchain Wallet Safe


      Creating a password has always been a standard encryption measure, but when it comes to the Blockchain wallet, you should know that youre not able to reset it if you ever lose or forget it. Thats the reason why you should keep it safe and secure. Ultimately, if you would like to restore your wallet, this happens via backup phrase, which is the second thing to note and hide well. I always recommend making several copies of both the phrases and put them in different places.

      Whats more when speaking of security is the two-factor authentication. This feature will additionally protect your coins by requesting a specific piece of information every time when you log into your wallet or perform an action with it.

      Two-Factor Authentication

      The Two-Factor Authentication feature requires you type in specific information when you log into your wallet or request to make a change. It might be an SMS, a PIN code or a text to fill, depending on your choice


      Password encryption is one of the basic processes to implement in each wallet. Whats different here is the availability of two separate phrases a password one and a backup one to restore your wallet with. Anyway, keep them both safe and secure

      How Secure Is Blockchain Technology


      Blockchain is often touted as a secure way of storing information, but just how secure is it?

      While nothing is 100% secure, blockchain is designed to be immutable, tamper-proof and democratic. It achieves this, more or less, through three defining characteristics:

      1. Decentralization

      2. Cryptography

      3. Consensus

      The complex interplay of these characteristics are what secure blockchain transactions and discourage foul play. For the purposes of this article, well look at the first and most well-known blockchain of them all: Bitcoin.

      Traditionally, anyone wanting to store, share or process information has to own it. This involves creating, borrowing or buying that information, obtaining permission to use it and then ensuring everyone is aware of any changes. Sound confusing? It is. Handling information this way can easily become a complex game of telephone with hundreds of weak points and a high margin for error.

      Blockchain, on the other hand, distributes the same information to every user on the blockchain network. When you make a change, the network validates it and then miners add that transaction into a new block, which is then added to the blockchain.

      Cryptography: The Perfect Disguise

      If decentralization is the bones of the blockchain, cryptography is the muscle — the sinewy, complex mathematical algorithms that deflect attacks.

      Cracks In The Facade

      Better, But Not Perfect

      What Is The Blockchain Exactly

      Blockchain is a distributed ledger that uses hash functions to provide a unique fingerprint of every transaction, recording and authenticating them. When each transaction is signed and verified as unique, its sent to join a block of other transitions and becomes impossible to modify. These blocks together form the blockchain.

      How secure is the blockchain? Its protected by the 256-bit SHA hash functions, the same level of security that banks, the military, and virtual private networks use to encrypt their systems. But unlike encryption, which can be decrypted, SHA hash functions provide a unique fingerprint for each transaction that cannot be reconstructed.

      In other words, cryptography in blockchains is used to sign the data with a unique, unbreakable identifier that other network participants can verify using the same cryptographic algorithm.

      The blockchain also builds security by consensus. For it to be hacked, someone would need to take over 51% of Bitcoin mining capabilities, which would be incredibly unlikely. However, your cryptocurrency wallet isnt necessarily secure and thats where youd store your bitcoin.

      Cryptocurrency And Blockchain Security

      Cryptocurrency trading companies are perhaps the most often associated with blockchain technology, primarily Bitcoin but also Ethereum, MobileCoin, Javvy, and Coinbase.

      Given cryptocurrency isnt something we cant keep close as close as, say, a wallet in our pocket blockchain technology secures transaction data thanks to its rules that no transactions can be altered after being inputted. In addition, the fact that recorded transactions are traceable means theres transparency in the event of a cyber attack.

      Are There Security Risks Associated With Cryptocurrency

      Is blockchain safe?

      Yes, there are some security risks you should be aware of. Well break them down here.

      These are just a few of the security risks associated with cryptocurrency, but there are others that continue to crop up as the crypto ecosystem evolves. The U.S. Federal Trade Commission updates its information on crypto scams and security as they develop, so it may be worth checking every so often.

      Reason #: Bitcoin Is Decentralized

      Bitcoins distributed network has over ten thousand nodes all over the world that keep track of all transactions happening on the system. This large number of nodes ensures that if something happens to one of the servers or nodes, others can pick up the slack.

      It also means that trying to hack into one of the servers is pointless. Theres nothing there you could steal that the other nodes and servers couldnt prevent, unless you happen to control 51% of the nodes not impossible, but extremely unlikely.

      Cold Storage Vs Hot Wallets

      Conventional wisdom dictates that if you’ve got more virtual currency than you’d be comfortable carrying around on your person, or you intend to hold it as a long-term investment, you should keep it in “cold storage.” This could be a computer that’s disconnected from the internet or a specialized USB drive called a hardware wallet.

      Dedicating a computer to store your cryptocurrency or shelling out for a hardware wallet isn’t an option for everyone, however. Well known devices such as the Trezor and Ledger cost between $120 and $220 and, by design, add complexity and a few extra steps to every transaction. Software wallets, by contrast, are usually free and easily accessed though, ultimately, less secure.

      What Is The Purpose Of Cryptocurrency

      Cryptocurrencies are digital financial assets that are designed with the purpose of acting as a medium of exchange using the science of cryptography to secure transactions, create global currencies, eliminate government control and exchange rate issues, and control the creation of additional units of the currency.

      Cryptocurrencies were introduced as a disruptive financial technology , which would make global transactions easier, faster, and more secure, putting control directly in the hands of the concerned parties. This could also eliminate banks and money transfer services.

      The digital currencies claim to make storing, spending, and transferring “digital money” secure, super-fast, and unaffected by any fees, exchange rates, or governmental regulations.

      The purpose of cryptocurrency and its underlying technology, however, is not limited to financial institutions, currencies, and transactions. Securitizing data, identity protection, creation of a decentralized economy, and storing personal data securely are a few of the initial purposes for which the blockchain technology was brought to life.

      Although the uses of the blockchain technology behind cryptocurrencies is multifold, blockchain identity use cases are what is gaining the most traction from technology aficionados and enthusiasts worldwide.

      Blockchain technology now can be used to identify applications in areas such as digital identities, passports, e-residency, birth certificates, wedding certificates, and other IDs.

      Using Exchange Default Wallets Is Risky

      Is Blockchain Safe? Blockchain Security Explained

      Many newcomers buy cryptocurrency from an exchange, such as Coinbase or Kraken, and leave their holdings in those sites’ “custodial” wallets. But like any other online entity, exchanges are vulnerable to hacking — and as the crossroads for many billions of dollars of transactions every day, they make for particularly attractive targets.

      The cautionary tales of Mt. Gox, which “lost” 750,000 of its customers’ bitcoins in 2014 NiceHash, which was robbed of $60 million in December 2017 and a close call at Binance in 2018 show the risks associated with leaving your coins in an exchange’s online wallet.

      How Safe Is Blockchain With Hashing

      The main difference between Hashing and Encryption is that Hashing is indecipherable one-way encryption. While in the previous method, you can have access to decrypt the ciphertext with a key, hashing makes it impossible to see the original data. However, the hash value collates with the original value. Hence, hashing mechanisms are good at keeping track of the originality of the source.

      Current Blockchain Storage Products Available

      Blockchain technology is still in its infancy. However, there are a few organizations developing some great ideas. and are two Blockchain storage products available right now. These are early examples of this kind of technology, and there will be more to come. Filecoin is another product allows individuals to mine Filecoin by sharing storage space . Filecoins can then be traded for storage space on the Filecoin network or converted to Bitcoin, altcoins, or cash.

      Healthcare And Blockchain Security

      Healthcare institutions store a bevy of confidential data regarding patients, from banking and insurance details to medical records and family history. And cybercriminals know this all too well, as they love targeting this industry with phishing attempts.

      The decentralized nature of blockchain technology makes it more difficult for hackers to enter a database there are too many entry points to choose from. Moreover, limiting user permissions on private blockchain networks means there are potentially fewer internal actors who might compromise this data.
