As of last Monday, the entire crypto community along with Stellar holders could take a breath and enjoy seeing some of their favorite currencies bouncing off and recovering from the latest market dip. But not all news was in the spirit of redemption as it was discovered by the researchers from the National University of Singapore that Ethereum is vulnerable when it comes to operating with smart contracts. The fact that Stellar was immediately brought in to the story as a safer substitute, made us analyze the way Stellar ecosystem is operating with smart contracts. What happened to ETH smart contracts and is Stellar able to take over with its own smart contract technology?
Ethereum’s Vulnerability and Stellar Jumping In?
Discovering flaws and high-level vulnerability in ETH smart contracts was quite a shocker as well as what seemed to be a never-ending market dip that fortunately ended with last Monday when the majority of currencies started to rise back up.
A team of researchers from the National University of Singapore found out that Ethereum’s smart contracts are more than sensitive and vulnerable to hacker attacks, and the vulnerability issues they discovered on this occasion could be marked as anything but utterly safe and reliable. The thing that probably shocked them the most was the fact that one of the users was able to lock over 200$ in ETH on the Parity Project blockchain by manipulating smart contracts.
The mentioned individual who decided to manipulate the contract publically published his discovery in Github community, stating that anyone can kill your contract. He even named the conversation “Anyone Can Kill Your Contract”, which was more than intimidating.
He pointed out that he was able to adopt a contract that wasn’t even his own and then terminates it easily by manipulating with the flaws he had found while examining the way smart contracts are operating on Ethereum.
There were some suspicions among other community members that got involved in the conversation, but he was soon able to prove his point and confirm that anyone can indeed kill your contract due to the present vulnerability in form of a flaw.
The fact is that ETH smart contracts are pretty flexible, but unfortunately, flexibility, in this case, doesn’t guarantee safety. This was a massive blow for Ethereum, as this currency is one of the most appreciated digital assets in the world of blockchain technology.
The researchers from the National University of Singapore along with the researchers from UCL decided to test ETH smart contracts for vulnerability.
Testing Smart Contracts: Ethereum vs. Stellar
The researchers from the National University of Singapore and UCL then decided to download all live smart contracts that actively existed on Ethereum’s platform at the moment of testing. There were nearly a million of active live smart contracts and as they started with their testing, they have discovered that more than 34000 smart contracts showed vulnerability with over 2000 smart contracts showing high-risk vulnerability, which meant that these contracts could be manipulated “easily” by a third party that would in majority of cases represent hackers who want to take advantage of unintended issues in ETH smart contracts.
For further testing, the team has gone on by choosing 3759 different smart contracts so they would be able to check the results again. And, the results were devastating as the team was able to find major vulnerabilities and flaws within only 10 seconds of testing for positivity.
That being said, they have confirmed that they managed to prove the fact that Ethereum smart contracts could be manipulated just like with Parity Project blockchain system where smart contracts can be terminated even by individuals who don’t have ownership over certain smart contracts. It was also confirmed that smart contracts on Ethereum can be manipulated into sending funds to anonymous addresses that would most certainly belong to hackers.
That is exactly how a new opportunity arose for Stellar and its smart contracts.
Stellar Smart Contracts
Thanks to the various technological concepts implemented in Stellar’s smart contracts, these contracts are made more expressive but less flexible at the same time. Decreased flexibility, in this case, means that there is less room left for hacker attacks, which makes operating with Stellar smart contracts safe and secure.
To assure all operations with smart contracts are safe and immune to any type of vulnerability issue, Stellar is using various authentication constraints created in form of codes and encryptions.
One of the authentication processes is Multisignature verification. In case Ethereum smart contracts had this option, the bad case of vulnerability within the Parity Project could definitely be avoided. Multisignature is actually a concept that requires confirmation from a unique second party individual who has to verify the action before any action is made reality, that way avoiding hacker attacks.
To back up the initial concept in form of Multisignature, Stellar has also implemented Batching/Atomicity. Batching is a concept that allows any user to schedule multiple operations within a single smart contract. If any of these operations would fail to be delivered, all other operations would fail. To back up this process as a completely safe concept, none other operations can be added to the smart contract after the request for execution, so hackers are not able to intercept a certain smart contract and add more operations to the original smart contract.
To assure that none other transactions can be additionally added to any smart contract, Stellar has found a solution in form of Sequencing protocol. Thanks to sequencing, smart contracts would not be qualified for execution if another transaction would be added to the original existing number of transactions during the execution of smart contracts.
Finally, thanks to the time bounds, any contract that has not been executed and completed in a timely manner and within the given time frame would be marked as nonvalid.
How is Stellar doing at the Current Moment?
It seems that Stellar XLM is doing a pretty solid job with recovering from the latest market crash.
After the latest change in its price in the course of 24 hours, XLM managed to rise back to trading in the green by having a rise of 2.88% against the dollar. Due to the latest positive change in XLM’s price, one XLM can now be bought at 0.23$ per one unit.
In case Stellar, now ranked as 8th best currency on the global coin ranking list, manages to replace Ethereum with smart contract operations and drive new ICOs to Stellar network, Stellar could potentially grow to the price of around 21$ the next year around this time.
Is Stellar able to take over the spotlight over ETH smart contracts and how far could XLM go?

3 Coins Coinbase Will Adopt Next
Coinbase is one of the largest and most popular cryptocurrency exchanges in the world. However, throughout its existence, it was very picky when it comes to which coin it will adopt. So much so, that it has become a very large achievement to get support by the exchange.
Recently, however, Coinbase has decided to act on its users’ wishes and expand its list of accepted coins. In theory, this was a big deal, and the exchange actually started looking into a lot of coins. However, it only adopted a few of them. Right now, Coinbase is supporting Bitcoin, Ethereum, Bitcoin Cash, Ethereum Classic, Litecoin, USD Coin, Basic Attention Token, and 0x.
Even so, Coinbase wishes to add more of them, but only after it ensured that the coins are a part of legitimate, non-controversial projects. As a result, the entire crypto community started speculating about which coins will be added next. This will also be something that we will try to answer today, by listing three projects that are the most probable candidates.
EOS or Ethereum On Steroids, as some like to call it, is a more than a decent project that has made headlines multiple times this year due to its progress. It managed to launch its own MainNet, which made it perfect for dApp development and smart contract creation. This makes it similar to ETH, but many…
What Will It Take For Bitcoin (BTC) To Rise Again?
It is no secret that 2018 has been a terrible year for cryptocurrencies when it comes to their value. Things looked so bright during the first few days of this year, with Bitcoin hitting $20,086 per coin, and every altcoin reaching new heights. However, it was not to last, and soon enough, the market crashed, and prices went down.
What followed was months and months of a heavily bearish market that kept pushing the prices further and further down. It prevented any attempt of recovery, although several of them gave it their best shot.
Despite a situation like this, crypto investors never forgot the potential of Bitcoin, and many have been predicting another bull run that would have the same results. Those expectations were quite large, and potentially even unrealistic at first. Now, however, as the year approaches its end, it doesn’t seem like anything will happen. The community started to wonder why that is, and what would it take for another bull run to emerge, which is what we will try to answer right now.
What does Bitcoin need in order to have another bull run?
1. Bringing regulation
The crypto space remains highly unregulated in most parts of the world, which is one of the largest reasons why BTC remains dormant. While there are attempts to regulate it, these attempts are made even more difficult due to the fact that the market is constantly changing and…
Stellar plans to Airdrop 150 Million USD in XLM to Blockchain Wallet Users
Recently the Stellar Development Foundation partnered with Blockchain Wallet to airdrop $150 million value of XLM, to the owners of the wallet. The Block declared that the first batch of XLM would be shared this week for all users who signed up to use the Blockchain wallet.
The team behind the stellar Development Foundation hopes that this partnership will make XLM a real rival for other cryptocurrencies from the market.
The co-founder of Stellar, Jed McCaleb declared the following about the airdrop:
“We believe that airdrops are central to creating a more inclusive digital economy. Giving away lumens for free is an invitation to communities to design the services they need.
By working with Blockchain to increase the availability and active use of lumens on the network, we will increase the network’s utility by many orders of magnitude.”
Just $25 value of XLM each
To share some respect to the worth of XLM will distribute for each user, the team of Blockchain wallet declared that after verifying the identity when signing up to the wallet, $25 value of XLM will be shared to each. Furthermore, there will be a first- come and the first-served clause in this airdrop which says:
” Offer available until XLM giveaway supply is depleted. Limit of one XLM airdrop per person, unless participating in any bonus activities.
A person can receive the XLM airdrop in only 1 Blockchain Wallet. XLM…
