So, what’s a decentralized system? In simple words, we can say that a decentralized system works with no servers and each member is permissible to execute transactions. But in the case of the blockchain, each member must have to do some system-tasks as well, such as; storing transactional data.

cryptocurrency Security

Fork: Even a group of members can run an alternate-version of reality, which is called “fork.” The fork works by the similar regulations as the original decentralized system – though it might have a diverse state.

Let’s enlighten you about the hierarchical nature of cryptocurrency security!

First Layer – Tokens and Crypto Coins

  • One of the first and foremost thing in the crypto world is your cryptocurrency security.
  • Whenever you choose a cryptocurrency, you take all the perils and risks related to the protocol.
  • If someone can recognize and utilize protocol flaws, they can compromise the whole network, even including you; it won’t be much important which exchange/wallet you are using.

In the first layer, you can find two different types of currencies which include, the coins (Bitcoin, Ethereum, Bitcoin Cash etc.) and all ICO-issued tokens such as; MOBI or EOS.

What is the Difference?

Well, the difference is in the technical features. Each coin is either an independent network protocol or just a copy of some of it. When you research a crypto protocol from a security stance, make sure to find out if it can be centralized.

Let’s take an example!

In the case of Bitcoin, it’s now centralized around four major mining pools which also means that if all of them collaborate, they can possibly compromise the whole network.

Another advice! Whenever you look for proof-of-stake crypto, make sure to have a look at the genesis. This is also quite imperative, as whoever keeps the preliminary and initial stake can vote for transitions, as well as the network will be also trusting those who have higher stakes. If we take an example of NEO, a PoS network of China, which is same as Ethereum, was distributed 50/50 amid its ICO sales and developer community – unlike Ethereum distribution. Also, the NEO token distribution makes sure that no major stakeholder from the exchange platform or the developing side has enough stake to compromise the whole network.

Tokens

  • Now if we talk about tokens, all of them are based on a smart-contract aspect of few of the coins, which means their reliability and security is first based on the parent cryptocurrency – only subsequently on the smart contract’s code that issued it.
  • Mostly, all ICO coins (tokens) are based on Ethereum and just some of them are issued by smart contracts.
  • Also, it is imperative to point out that Ethereum got hacked a few years ago due to the DAO protocol hack – later hard forked and rolled back to the state. This also shows that the founders of Ethereum probably have a time machine as it looks like they have the ability to go back in time – yet again if it’s required.

Second Layer – Exchanges

One thing that everyone must understand about the exchanges is that they are written in custom-code with infrastructure security and has got nothing to do with blockchain. If we talk about an exchange, it is just a standard centralized web service arrayed in a data centre. That’s why whenever we talk about the exchanges, we always mention reliability and trust.

Almost every month we hear news about the data breaches and security events that occur because of exchanges.

Examples

Here are some latest examples!

  1. Back in December 2017, $63 million in cryptocurrency was stolen from NiceHash by hackers.
  2. At the beginning of this year, January 2018, more than $500 million in cryptocurrency was stolen from Coincheck by hackers.
  3. In February 2018, almost $195 million in cryptocurrency was stolen from BitGrail by hackers.

The hype around cryptocurrencies is due to the number of data breaches. Many exchanges have recently started their business – without investing in proper security measures. Simultaneously, if someone steals tokens/crypto coins from an exchange successfully, it’s nearly impossible to do anything about recovering it.

Third Layer – Wallets

Well, the third layer is linked to your personal security in the crypto world and you must’ve heard a lot about it before.

When you select a wallet for cryptocurrencies, you’ll have two options:

  1. Hot Wallet
  2. Cold Wallet

Hot wallet Vs Cold Wallet

  • The hot wallet is just like an account in exchange or in simple words, it is a website-based wallet.
  • In the case of a hot wallet, your tokens/coins are under the control of your wallet provider.

Whereas, a cold wallet can be a hardware, software or just a paper.

US Officials Commend Blockchain Surrounded by ICO Distress

Want create site? Find Free WordPress Themes and plugins.

On Wednesday, a message was broadcasted by U.S. government officials at the DC Blockchain Summit in Washington-even as securities officials cautioned exchanges who offer ICO tokens trading. James Sullivan (Deputy Assistant Secretary of services at the Commerce Department’s International Trade Administration) remarked during his address;

“We cannot make policy in the abstract” and concluded by saying;

“I would welcome all of you in the audience to reach out … and to hear your recommendations”

There’s no doubt that Sullivan showed support for the use of blockchain inside the trade finance chain, especially for smaller companies with hardly any resources, as he stated;

Blockchain

“The companies that are usually hit hardest by that gap of trade finance are small- and medium-sized businesses”

Attendees who talked to CoinDesk, turned out to be more divergent on the question of blockchain’s use in government and also on the the subject of cryptocurrency regulation, which was the greatest concern at the event as well. Scepticism was also expressed by one of the employees of a major blockchain startup that the U.S. officials would seriously obligate to utilize this tech, conflicting that agencies might be served a lot better, seeing at the advances of tokenization.

Chief data architect of OPM (Office of Personnel Management), Marcel Jemio, alongside Mark Fisk, who’s an IBM Public Service Blockchain partner stated that blockchain could be utilized in order to aggregate government employee information in a more efficient and well-organized way.

Fisk stated;

“I think blockchain in a lot of cases is going to be an enabler of solving the problem, but not necessarily with solving the problem only with blockchain”

Jihan Wu, co-founder of Bitmain also revealed that the bitcoin mining hardware giant wants to invest in startups and looking forward  to make a “private central banks” that utilize cryptocurrencies. Wu thinks that tokens on the market today will eventually come to be viewed as securities under traditional meanings.

CoinDesk was told by conference attendees that they’d definitely appreciate regulation, specifically relating to ICOs, whereas others asserted that these emerging regulations at this time would probably lodge businesses into inflexible models ill-suited for such a quick moving situation. Attendees also showed their concern about the unreliable treatment of cryptocurrencies by the U.S. government, specified that the IRS considers bitcoin as property and the CFTC views it as a commodity.

But at the same time, two members from a cryptocurrency services company said that they believed such dissonance could eventually profit the industry, with the lack of agreement by the SEC, the CFTC and the IRS, eventually imposing further discussion on the finest way onward.  Brian Quintenz, a commissioner for the CFTC, was also seen at the event, firmly encouraging more self-regulation in the cryptocurrency space. Quintenz even told the audience that cryptocurrency platforms should come forward and self-regulate.

Bitcoin Hacker Helps FBI Track Down a Murderer

Want create site? Find Free WordPress Themes and plugins.

 

A bogus dark-web website offering hitman services had its information leaked by a hacker known by the name “bRpsd”. The data that was disclosed provide leads to the FBI on their investigation of a man who murdered his wife.

Stephen Carl Allwine, 47, of Cottage Grove, Minnesota, murdered his wife, in November 2016. Allwine tried to stage the murder as a suicide by placing a 9mm pistol next to Amy Allwine’s elbow. Although, the detectives were quick at gathering the electronic evidence- computers etc. and arriving at the conclusion that it was a murder. He was then arrested in late January and charged with second-degree murder based on the forensic interpretation of the evidence.

Hacker turns Hero

In May 2016, a hacker that goes by the name “bRpsd”, violated the database of a questionable website on the dark web, which supposedly offered hitman services.

The site, “Besa Mafia”, requires you to register on the site anonymously. It offers a link between customers and hitmen, where they can decide on a price for murder, ranging from $5000 to $200,000. Whereas, customers that just require having someone beat up or set their car on fire could hire contractors for $500 and $1000.

The data dump was uploaded by the hacker onto a public website which was consisting of user accounts, email addresses and messages between the admin and its clients, “hit” orders and a folder called “victims”, which included additional info on the pawn.

The scam nature of the site was emphasized on, pointing out that it clearly just collected money from its clients.

An independent researcher, Chris Monteiro, also hacked into the site to conclude that the owner(s) of Besa Mafia had made at least 50 bitcoins ($127,500) from the hoax operation.

Arrest of Stephen Carl Allwine

The leaked data from the Besa Mafia database helped the police in investigating the murder of Mrs. Allwine. While analyzing her husband’s devices, the discovered that he had been a frequent visitor of the dark web since 2014. The pseudonym used by Mr. Allwine on the dark web “dogdaygod”, was also linked to his email address, “dogdaygod@hmamail.com”. Further investigation brought them upon the conversation between Besa Mafia and Allwine, which included a bitcoin address and linked the husband directly to the “dogdaygod” pseudonym.

According to a criminal complaint, the suspect paid between $10,000 to $15,000 to the hitman service to kill his wife. The complaint explains how the hitman was under instructions to shoot Mrs. Allwine at a close range and burn down the house right after.

Although, the Besa Mafia communicator told Allwine that “local police [have] stopped the hitman [from] driving a stolen vehicle and taken [him] to jail prior to the hit,” due to which the service is left incomplete. Sergeant McAlister reported, during that time, “no one was apprehended in Minnesota and western Wisconsin in a stolen vehicle and possession of a gun.”

The hacker’s data breach provided a push to the investigators in the right direction. On March 24, 2017, the Washington County District charged him with first-degree murder.
