Litecoin MimbleWimble Update 2020

Litecoin MimbleWimble Update

Litecoin for some time has been creating noise about assuaging the risks associated with the transparent ledger system in Blockchain technology. With the upkeep of a transparent ledger, Blockchain provides a medium through which all the transactions can be viewed because the mechanism supports it. Keeping that in mind Litecoin has promulgated two new draft Litecoin improvement Proposals that are designed and furnished with details that would improve the privacy features of the noted network. 

The authors of the proposal Andrew Yang, David Burkett and Charlie Lee are of the opinion that the transparency has had a drastic impact on the firm’s functional fungibility. In simple words Fungibility is the innate quality of a good or an asset that makes it interchangeable with another good or asset of the same quality. 

Charlie Lee, founder of Litecoin had earlier pronounced plans to discover privacy technologies because the scaling issue is behind them. Now a more pressing issue is fungibility and Privacy.

Why should you know this?

Because this is the dilemma that most coins like Litecoin and Bitcoin are facing currently. It is not private because one can see who held what coin in which address in the past. And competition knows this! That said, fungibility faces risk in the long-term. The Litecoin foundation has outlined the proposal from the observation it has made. It had strong reasons to outline the drafts. 

It is a possibility that personal information is collected from the respective IP address or exchanges which can be leaked and tied to the addresses which is risky. It has been observed that as and when entities link addresses to distasteful activities the taint metric can be applied. Important organizations including governments have already started blacklisting addresses. 

Privacy seems to be one of the biggest priorities when it comes to improving protocol because with greater privacy comes greater functional fungibility. The Litecoin foundation has started working on integrating scalability and privacy-focussed protocol called Mimblewimble which was a tongue-tying curse from the Harry Potter series.

About MimbleWimble

MimbleWimble is a protocol that came into being when an anonymous user in Bitcoin developers chatroom. MimbleWimble transactions are derived from another transaction type called confidential transactions. The confidential transactions lets the senders to encrypt the amount of coins which are to be sent using blinding factors. Blinding factors is nothing but a random value which is used to encrypt the coin amount in the transaction. The user selects the blinding factor which encrypts the amount that is being transacted, so the transactions are clouded but are verifiable therefore substantially increasing privacy.

How will MibleWimble work?

Coming back to the proposals, the authors are looking at implementing Mimblewimble protocol as the opt-in new transaction format through extension blocks’. Extension blocks are soft forks lookalikes but are much more advanced. It appears like a regular base block but there is a major difference. While a base block is cryptographically interlooped with the previous and the next base block chaining these blocks in a chronological manner; each canonical block links to the corresponding extensions block.

These extension blocks function concurrently with the main chain canonical blocks at an average interval of 2.5 minutes. The actual functionality will be to ensure that private transactions occur inside the EB. Users can then use Mimblewimble to move their coins to and from the Extension block through an integrating transaction. 

The proposal has without any obfuscation stated the opt-in integration and how it will impact privacy and scalability. The proposal also handles the fusion between Extension blocks, canonical blocks and the coins.

Litecoin MimbleWimble & Extension Blocks are truly Novel

Although the move hints at averting risks, the challenge is unqiue because Extension blocks have never been implemented on a live Blockchain before. It will obviously require time, analysis and audits to ensure there are no issues or bugs. It’s best not to rush such a robust and complictaed overhaul, as there is potential danger to lose coins or inflate the supply.

The Latest Litecoin MimbleWimble Update as of 7/4/20:


Even though this daunting task has proved incredibly complex, the wait will be totally worth it. And good news! In terms of the roadmap, July 2020 is still slated for the initial block download. August is set for chain reorganization logic, and the Activation logic and the launch of the test-net is set for September 2020! This is very exciting news for all Litecoin holders.

The Future of Litecoin

Litecoin has always been a very important cryptocurrency to the space, and as we move into the future, we imagine Litecoin has the potential to be one of the most widely adopted and used cryptocurrencies in terms of mass transactions on a daily basis.


We envision Litecoin having real potential in mastering micropayments in the future of eCommerce. As most individuals choose rather to store and save bitcoin much like a commodity like gold, Litecoin has a real chance of being a cryptocurrency that is actually used as a currency, not a hybridized currency / commodity like bitcoin has become.


Litecoin is the perfect user friendly and corporate friendly cryptocurrency and is incredibly fast and secure. It has our vote!

Huobi top official arrest – Are these rumors or a reality?

huobi arrest
rss

CryptoQuant, a crypto information provider, has indicated a significant increase in Bitcoin funds outflows from Huobi global. This is a development that comes when the firm has issued in public denial about rumors of an arrest of one of its executives. But as per the Chinese media, crypto exchange Huobi Chief Operating Officer (COO) Robin Zhu was under investigation by the Chinese people. 

In a tweet thread that was posted on November 2, Huobi quashed rumors about the supposed arrest of a Huobi senior executive. It came out with the clarification stating: 

“All of Huobi’s management team members have been accounted for and have not been detained or arrested,” the firm said. “We understand that the spread of false information can lead to concerns about the safety of user assets, but please rest assured your assets are safe.”

CryptoQuant mentions that the outflow increase peaked after midday on Monday.

Huobi is a global exchange with monthly trading volumes above $170 billion. It has assured its users and the media that nothing such as this has happened. It so happened that Huobi COO Zhu Jiawei was reportedly unreachable on Monday evening and immediately after that rumors were afloat in the circles that he was being arrested. All of the social media was swirling with the news with local news channels also reporting on the rumors. 

The exchange said that Zhu was on a flight returning from a conference in Guizhou and that he would be attending a meeting in Beijing on Tuesday morning.

But, the assurances of Huobi haven’t stopped users from withdrawing funds and now they are viewing themselves in the same boat as users of OKEx. In fact, many hours before it directly addressed the rumors of an arrest, Huobi tweeted that it uses a multi-signature process for withdrawals so that the users did not have to rely on a single key holder. As for the rumors, the exchange claimed that Zhu was on a business trip and would be here this week for an important meeting. Huobi said that its operations were unaffected by these unsubstantiated rumors as per an earlier statement on its Chinese website. 

Bitcoin removed from Huobi rapidly

A greater likelihood is that the rumors are false but users are not taking any chances. As said earlier, there is a mass exodus of Bitcoin with its outflows hitting 4,241 BTC which is growing rapidly. 

“Looking at Huobi Netflow, BTC outflow has soared in the last eight hours.”

In the month of June, there were rumors that Dong Zhao, the co-founder of the Chinese crypto lending platform Renrenbit apparently cooperating with the police for investigations which is now a new trend in the Chinese markets. OKEx announced in October that the founder Star Xu also has been under investigation for weeks, and following that OKEx had suspended withdrawals of crypto assets from the platform. The statement came out at least one week after he was detained by the police and users are still not able to withdraw their funds. 

Source: CoinGecko

Huobi Token price today is $3.58 with a 24-hour trading volume of $257,890,383. HT price is down -6.6% in the last 24 hours as per CoinGecko.

Rumor or reality?

Huobi is surely the largest target for Chinese authorities and watchdogs cracking down on crypto exchanges, and all this has added to the jitters of the crypto investors. As of now, there has been no evidence proving that the COO had been arrested and the company has plainly denied allegations. But nonetheless, the markets reacted.

But as far as evidence and other events surrounding it happened, the rumors have been baseless. The Bitcoin and crypto trading platform also confronted these claims in a tweet thread stating that they could share it with strong confidence that they are false. The exchange further stated that they have accounted for all of their executive team members and reassured users that all their assets are safe. 

“All of Huobi’s management team members have been accounted for and have not been detained or arrested. We understand that the spread of false information can lead to concerns about the safety of user assets, but please rest assured your assets are safe.”

Harvest Finance Hack Explained. Here’s how it happened.

Unscrambling the Harvest Finance hack and its aftermath

Harvest Finance, the Decentralized finance protocol was hacked for a staggering $24 million. The attack was a reminder to the crypto community that DeFi has sure risen to prominence but it has its own share of loopholes, and it is this that the attackers take advantage of. 

Harvest Finance attack details

The attacker directly attacks the protocol’s liquidity pools leading the arbitrage attack using a large flash loan – a type of uncollateralized loan. The attacker later returned $2.5 million but in a mere seven-minute act, the entire hack was complete, leaving the protocol stakeholders bewildered. 

In further addition to the details of the hack, the protocol revealed that the hacker manipulated prices on one money lego which is the Curve Y pool. This was done to drain another money lego farm USDT (fUSDT), farm USDC(fUSDC) multiple times.

The attacker then converted the funds to renBTC and later excited to Bitcoin. renBTC is not synthetic because it does not rely on any liquidation mechanism and it is certainly not the price of Bitcoin on Ethereum. It is a one-to-one representation of Bitcoin on Ethereum which can be redeemed for BTC at any time and in any amount. 

harvest finance hack

The native token of Harvest Finance, FARM fell 54% to $101.79 when the news of the hack came forward. Following the attack, the amount of money that was locked in the protocol plummeted from $1 billion to $575 Million On October 25th. The investors were so fretful that they pulled their deposits back. 

Harvest Finance acted accordingly and withdrew all the funds from the shared pools almost immediately after it had completed a fine evaluation of the attack. It began with reconstructing the processes which included DAI, USDC, USDT, TUSD as well as WBTC and renBTC. The funds are currently present in the vaults safely so that they are not exposed to further market manipulation. The hack did not involve DAI, TUSD, WBTC, and renBTC, and the depositors in these vaults were not affected.

How was the hack carried out?

The mechanics of the protocol has allowed for the execution of such an attack. Let us see how:

The investment strategies used by Harvest involves calculating the real-time value of assets that are invested in the base real-time protocols. The value of the assets is then used by the vaults to calculate the number of shares to be used to the user depositing the funds. The same value of the assets is also used when the users take out funds from the vaults.

Payout is then calculated upon the user exit. What also needs to be noticed here is that the assets inside some of the vaults are deposited into shared pools of underlying DeFi protocols. These are subject to market effects such as impermanent loss, arbitrage, and slippage. This means that its value can be manipulated through larger volumes of market trades. 

The attacker knew this well and had exploited the impact of the impermanent loss of USDC and USDT inside the Y Pool of Curve.fi by manipulating the asset value to deposit funds into the vaults and obtain the shares for a beneficial price. 

The aftermath of the Harvest Finance Hack

Harvest Finance’s Twitter account has been buzzing with messages and activity. The protocol has taken full responsibility for the engineering attack and has ensured that in the future such attacks will be countered and mitigated. The protocol has made it clear that formatting a disaster management plan to assist those who are affected will be the top priority for the protocol. 

The protocol is investing its resources to catch hold of the scammers and has already provided a list of Bitcoin addresses of the hacker where it believes that the stolen funds may have moved. It also had taken immediate action by asking prominent exchanges like Binance, Coinbase, and Huobi to block the attacker’s addresses. It further said that there is:

“A significant amount of personally identifiable information on the attacker, who is well-known in the crypto community.” Not willing to dox the cyber-thief, Harvest Finance is now offering a $100,000 bounty “for the first person or team to reach out to the attacker”.

Harvest further tweeted that the $2.5 million returned by the hacker will be distributed to the affected depositors on a pro-rata basis using a snapshot. The attack on Harvest comes only six weeks after the attacker escaped with $8.1 million in Bitcoin from another DeFi protocol BZX, however, BZX managed to recover the funds.
