The first step to using a bitcoin is obviously to obtain a Bitcoin wallet address. Without it, you can’t send, receive or store bitcoins. So before you get bitcoins, you’ll have to buy, download or create a bitcoin wallet.

Your wallet acts as a personal interface to the Bitcoin network, which stores private keys that give you access to the bitcoins.

A Bitcoin wallet is basically an app, device or website that controls your private keys.

Different kinds of Bitcoin wallets

Different Types of Wallets:

There are different ways to use Bitcoins, so there are different types of Bitcoin wallets as well.

  • Online wallets – these can be accessed on the web from any Internet connected device.
  • Bitcoin hardware wallets – these are physical devices designed to store bitcoins.
  • Software wallets – these are applications that can be downloaded to your phone, computer or tablet.
  • Paper wallets – these are bitcoin private keys that are printed on paper from a computer.

Wallets secure funds by protecting our private keys.

Let’s discuss these types in a bit more detail.

Online Wallets:

Also known as Hot wallets are basically bitcoin wallets that are accessible on internet connected devices like mobile phones, tablets, and computers.

They can be accessed using a user-set password and store your private keys on the web.

Eg: – GreenAddress and SpectroCoin

    

The advantage of using online bitcoin wallets is that they can be accessed from anywhere in the world and are best of regular or frequent transactions. Although, it isn’t the best idea if you’re planning on storing your bitcoins for the long term. There is an issue with the security since the private key is entrusted to an online service, there could be a scenario where the whole database of the service would get hacked and you’d have to say goodbye to your holdings or the service gets hold of your account.

Thus, it is recommended that you opt for online wallets when it comes to more frequent transactions.

Hardware wallets:

These are physical devices built to generate bitcoin private keys offline. They keep private keys separate from internet connected devices and they are maintained in a secure offline environment.

The best and most popular BTC hardware wallets:

  • Ledger Nano S
  • KeepKey
  • Trezor

Hardware wallets are definitely a good choice if you’re considering factors like security and reliable storage of bitcoin. By generating private keys offline, you are able to ensure that hackers cannot access your bitcoins.

Even if the device ends up getting stolen it can be protected using a backup PIN code.

Software Wallets:

These are designed to be installed in computers and laptops. Only you will have access to the private keys that store your bitcoins.

Bitcoin Armory is the most secure, popular and stable software wallet.

Paper Wallets:

One of the safest ways to store bitcoins are Paper wallets, especially if you’re planning on keeping them for the long term. It basically involves printing the Bitcoin address and private key on a piece of paper.

Conclusion

These are a variety of options for you to choose from. It is your decision to choose what you find suitable for the storage of your coins.

Best Bitcoin Wallets for Android Devices You Should Consider Using Today

Want create site? Find Free WordPress Themes and plugins.

This post is going to be a detailed review on the best Android Bitcoin wallets however, I’m doing my part by warning you that mobile wallets are the least safe type of bitcoin wallets.
Read: Types of Bitcoin Wallets

The reason behind this is the fact that mobile devices can be easily stolen, lost or broken. The private keys will be stored on your device if you possess a mobile wallet. So, if your device gets destroyed, your coins can’t be accessed either. Meanwhile, if you have a backup pin created for your wallet that you have stored in a safe place, your coins can be retrieved.

Now let’s get on with the reviews!

  1. MYCELIUM Android Bitcoin Wallet

Mycelium is a well-known mobile wallet that provides advanced privacy and security features to its users. It is an open source software program and thus is frequently updated to become a safer and faster wallet in the market. The coins can only be accessed through the mobile wallet as it does not have a web or desktop interface.  One of the major benefits is that you can use Mycelium along with a hardware wallet in order to achieve maximum security of your coins.

  1. AIRBITZ Android Bitcoin Wallet

Airbitz is another well-known open source Android Bitcoin wallet. The wallet is quite similar to BreadWallet because of its simplicity but packs a variety of features to enhance the security of your coins.

  1. BREADWALLET Android Bitcoin Wallet

BreadWallet is known to be one of the simplest android wallets out there. It consists of very basic “send” and “receive” options which make it very easy to use. At the moment, it is only available for Android and iOS.

  1. JAXX Android Bitcoin Wallet

Jaxx is comparatively new and proves to be a strong option among the other mobile wallets. It has the ability to hold a diverse variety of cryptocurrencies, it can also allow you to access your funds from multiple devices. However, one drawback of Jaxx is that it is not an open source software program, which has raised to a lot of safety concerns recently. You are recommended not to store large sums of coins.

  1. COPAY Android Bitcoin Wallet

Copay is a multisignature wallet created by BitPay. Multisignature means that the wallet requires more than one person to approve a transaction before its confirmation. This gives it an increased amount of security if that’s your main concern. Copay has an iOS, Android, and desktop version.

  1. GREENADDRESS Android Bitcoin Wallet

GreenAddress is a solid choice for people who are well experienced with Bitcoin as it has a bit of a weak user interface. Regardless, it offers good features needed to keep your coins secure.  If nothing works out then GreenAddress has got your back!

 

Just a reminder that not every wallet application on Google Play Store is verified. Some apps are created with the sole purpose of stealing the coins you transfer on to the mobile wallet. So, you’re advised to do your research before trusting any unknown wallet. Be sure that you are downloading the official application and not a malicious wallet.

A Hard Drive Worth $75 Million That Won’t Recover

Want create site? Find Free WordPress Themes and plugins.

James Howells, the IT laborer who unwittingly disposed of a hard drive containing what is currently valued at around $75 million worth of bitcoin, knows where the missing hard drive is, but he can’t try to recover it. That’s because the city in which the fortune is covered won’t enable him to delve into the landfill.

The missing hard drive is sitting somewhere under 200,000 tons of junk in a Newport, South Wales landfill.

Howells used an old PC to mine a sum of 7,500 bitcoins in 2009. Presently, he sold the parts to the Dell M1710 on eBay after his girlfriend complained about the mining’s clamor. He kept the hard drive in a cabinet, just in case the bitcoins increased in esteem. However, he overlooked the hard drive, and after four years, he disposed of it with the trash.

Howells has not been able to get consent from city chamber to dig into the landfill to recover the hard drive. Doing as such would require particular hardware that is typically used as a part of criminal examinations.

He was informed that a situation where even the police needed to go digging would require a group of 15, incorporating diggers with compulsory personal protection equipment. He couldn’t reserve such an operation, so he set up a wallet for donations:

City Council Denies Permission:

A Newport City Council representative said somebody has reached them in the past about recovering IT equipment containing bitcoins, but the chamber has shied away because of the expenses of uncovering the landfill and treating the trash, as per Wired. Such an exertion would cost millions and be environmentally destructive, with no assurance that a working drive would be recuperated. Around 50,000 tons of waste is added to the landfill every year.

A city chamber representative said the drive has likely experienced genuine galvanic corrosion from landfill leachates and gases. The landfill isn’t open to the public use.

Howells has the public address for his bitcoin, so he knows the bitcoins have not been moved. Since the information is encrypted, any individual who finds the hard drive would require Howells’ assistance to get to it.

The blockchain immutability myth

The blockchain immutability myth

Immutability…. We use this word in daily routine to signify a thing, which can never change. Whereas, in the blockchain, this word is referring to the worldwide transactions. Which is adjust by the participants. Here, the basic approach is, once the block blockchain transactions are complete, it cannot replace or reverse by other transactions.

So, the theory goes. Because

Saint Augustine states, “The highest good, than which there is no higher, is the blockchain. And consequently it is immutably good, hence truly eternal and truly immortal.”

Two prominent examples are,

  1. Under certain conditions, through some necessary adjustment transactions, history can change itself. Here, the question is arises, it easy to bring new changes in the content of the blockchain? Is it really easy?
  2. According to cryptocurrency advocates, immutability achieves only in case of decentralization of economic mechanism. Which is not proper fall at the private sector of the blockchain. Because, they totally depend on the collective behavior of a known group of validators, who are not trustworthy.

Above two circumstances are totally wrong. Because in blockchain there is no immutability thing exist. The proper question is,

Under which circumstance the blockchain will or will not change? And,

Do those conditions match with the problem, we are trying to solve?

Instead, the chain’s behavior depends on the network of a computer system. Before we get into the detail of how we ‘ll summarize the basics of blockchain first.

Brief discussion on Blockchain  

A blockchain system is running onto the different set of nodes. Which may be in control of different companies. There is no individual node who control the others. While nodes are connecting with each other through a proper network. These nodes generate and propagate transactions and rapidly spread to other nodes via digital operations in some kind of database.

Every new upcoming transaction is verified by an independent node. Following are some terms of verification;

1.it is totally in obedience of blockchain rule and regulations.

2. it is completely a digital structure

3. If any transaction passes the test of nodes. It will enter to the local list of not confirm transactions means directly in the memory pool. While others will enter in the orphan pool. In addition, pass transactions will be forward to its peers.

With some intervals, a node which contains the set of as-yet unconfirmed transactions on the network generates a new block. Each block contains the hash (32-byt). Therefore, by creating a little block chain, each block includes the timestamp. Accordingly, link to the previous block via its hash.

Validation Process

Blocks move and verified by nodes across the network like transactions. For the acceptance by the nodes, a block must contain proper transactions including no conflict with other ones. Whereas, with the confirmation of the test, it is entering into the local blockchain and transactions are confirm. Any transaction which conflict with others will discard immediately. Whether they are in memory pool or orphan pool.

Participation of the chain, make the strategy to ensure the generation of blocks.   This ensures indicates that any kind of node. whether it is an individual or a group has no ability to take hold of the blockchain’s content.

Authentication and testing

Proof-of-work a public blockchain allow its users to generate block who has the ability to solve the tricky and fiendishly mathematical puzzle. Whereas, to prevent minority control in private blockchains, blocks are signed by authorized members. In order to create a lawful chain, a product needs to legalize validator by using mining diversity.

Two different validator nodes can generate conflicting blocks when both have the same previous points. However, fork happens. While different blocks are seen by nodes and leading them to have the different opinion about the chain’s history. These forks are resolved on the arrival of new blocks on branches by a blockchain software.

Shorter branch’s node spool back its last block and replay these two blocks on the longer one. Unfortunately, if you are unlucky and both branches will extend. Then the conflict will be resolved by the third and so on. In addition, with the increase in fork’s length, the probability of a fork persisting drops increases. After a small number of the blocks, it can be reduced to zero in private blockchain.

Here, the most important thing to remember is, each node is controlled by a particular person. Where blockchain has not authority to ask some changes in transactions. The main purpose of the chain is to help in sync. But, if participants want to change the rule, no one has authority to stop them.

That is why we need to stop asking about the immutability of blockchain. Because the answer is “no”. Arguably, we consider the conditions under which it needs changes.

 

 

The blockchain immutability myth

Public chain’s mutability

Let’s start with the above mention two examples. We will take the start with the claim that authorization process. Which used in blockchain cannot bring true immutability by public chains. e.g.

Ethereum blockchain faces a devastating situation in June 2016. “the DAO”, loophole found by someone. In which, $250 million were invested and start draining its speed. Which distract the both investor and creator’s intentions. After few days, the ethereum software updated to prevent from hackers. It was publicly supported by Vitalik Buterin that ethereum users will control their own computer system. As a result, a large number of users, blockchain comes with the new name and rules is ethereum. Whereas, minority reject this idea and keep going with ethereum classic. There were more choices for names like ethereum compromise or ethereum pure. Whatever, democracy is the democracy, and everyone has their own rights voice. In addition, ethereum is ten times more than ethereum classic.

Now, we will take a common way, in which blockchain’s immutability will be dilute. Recall that mining of bitcoin and ethereum uses proof of work scheme. Where you get a reward for solving a tricky puzzle. In addition, this reward increases the potential of the users and they solve the relating issues more efficiently. Network continually adjust the rate of block creation. In addition, 10 minutes in bitcoin or 15 seconds in

Immutability of blockchain

Bitcoin has faced the factor difficulty of 350,000x from last 5 years. Today, bitcoin mining is on hardware devices with cheap electricity and in cold weather. Antminer S9 mines the block 10,000 faster than a desktop system. Which burns 10 times more electricity than a system with cost $1089.

To undermine the immutability of bitcoin blockchain, you need to install more mining capacity, then the other network creating 51% attack first. Secondly, through proper testing and approval, mine your own secret branches. Finally, at desired time, release your secret branch to the network anonymously. Then, the whole process of a transaction will be without any scams or hacking issue. It is not easy to install a huge program. It needs a lot of money and electricity as well. And a common man or country who has the shortage of both. Unfortunately, are not able to adopt this way for immutability of bitcoin blockchain.

Let’s estimate the cost of a 51% attack which reverses a year of bitcoin transactions. At the current bitcoin price of $1500 and reward of 15 bitcoins (including transaction fees) per 10-minute block. Miners earn around $1.2 billion per year ($1500 × 15 × 6 × 24 × 365). Reasonably, they are not losing money. So, the total expense should be in the same range.

Rewriteable private chains

Now, let’s have a ride to private blockchains. Which was established for the needs of government and well-reputed organizations. According to the organization’s perspective, immutability is the commercial, legal and regulatory non-starter. Because it allows attacking the network anonymously. whereas, immutability can also be ashore in good behavior of other institutions. With whom, they have authority to sue or sign a contract. It is a bonus because private blockchains are less costly to run. Since blocks need just a node’s approval and digital signature. When a number of validators follow the rules. As a result, you get cheaper and stronger immutability than other digital currencies offer. Furthermore, the percentage of immutability may decrease when participants in chain decide to do so together.

Immutability is nuanced

People who don’t like the traditional banking system and government’s currency are perfect to use proof of work blockchain. Whose immutability rely on economic terms instead of participants. It may be an expensive operation. when parties agree to live with government or wealthy actors and bringing down the network. Accordingly, they believe that cryptocurrency technology and its value continue to grow and it will get more secure.

Finally, for most permission blockchain use cases. We probably don’t want validator nodes to be able to easily and cheaply substitute old blocks in the chain. As Dave Birch says “the way to correct a wrong debit is with a correct credit”. Rather than pretending that the debit never took place. Nonetheless, for those cases where we do need the extra flexibility, chameleon hashes help make blockchains a practical choice.

Good luck!
