Polkadot solves one of the biggest problems of Web 3.0

 


Between the interest rate hike and the rising crypto prices, one of the most important news for the industry almost completely disappeared yesterday. Polkadot's parachain system is expanding with a new feature, a cross-consensus messaging system (XCM for short). It enables communication between different blockchains. It's one small step for Polkadot founder Gavin Wood. And a very big one for Web 3.0 . Because XCM could solve one of the biggest problems in the industry in the near future: the dependence of many platforms on so-called blockchain bridges.


In Web 3.0, different blockchains such as Ethereum or Solana often have to interact with each other. They are not inherently able to do this due to several differences in their design. Many platforms use blockchain bridges for this. They allow communication between native blockchains using different tricks. And at a very high price.


Polkadot vs Blockchain Bridges

The gigantic security risk of these bridges has recently been revealed, especially in the DeFi sector. According to the analysis platform decentralizefinance.com , there are now over 70 of them. It has $25 billion worth of cryptocurrency flowing through it.


With just three attacks on such bridges, hackers stole nearly $1.5 billion in the last few months, such as $625 million in the worst DeFi heist in history in March 2022, the hack of the popular Play-To-Earn video game , Axie Infinity . You can read all the background information about this unprecedented raid and the danger of blockchain bridges for the industry in the current issue .

 The hacks on bridges will continue and continue to have disastrous consequences. They are an easy and very lucrative target. Vitalik Buterin, the founder of Ethereum, warned most drastically of the consequences in a blog post in January 2022. In his view, they could endanger the entire ecosystem in the long term:


If there are a hundred blockchains with their own dApps and these become dependent on each other through bridges, then an attack on one of these chains is enough to infect the entire system.


Polkadot shows a way out of this fateful situation. Since its invention in 2016, the project around Ethereum co-founder Gavin Wood has been working on a secure and fast platform for exchange among blockchains - without any bridges, via so-called parachains. 


Polkadot and its community are already hailing XMC as the future of Web3.0, the dawn of a new blockchain era. Regarding the release on Wednesday, May 4th, 2022, one of the technical leads of the Parachain system, Hoon Kim, explained:


I see traditional smart contracts on isolated blockchains as a kingdom surrounded by walls. Then we have bridges that are like a trade route that connected these nations together. Now we have XCM. It is the blockchain free trade agreement.


Hoon Kim, Technical Lead at Polkadot

Unlike Polkadot's community, the market has not reacted significantly to the historic milestone so far. The Polkadot price has risen by ten percent since the release of XCM on Wednesday and has thus performed well on average

Not a bear market: According to the analyst, the current BTC decline is the same as in previous Bitcoin cycles

  According to one analyst, Bitcoin is behaving the same overall this year as it has in previous cycles. Bitcoin ( BTC ) will have “at least one more boost higher” before hitting all-time highs this halving cycle, analysts are currently saying. The well-known analyst TechDev has spoken on Twitter about the current state of BTC and said that contrary to many opinions, nothing unusual has happened in BTC/USD in 2022. Bitcoin in 2021: Nothing to see here Sentiment has also taken a hit, falling 40 percent from November's all-time high of $69,000. There is still “extreme fear” in the bitcoin and altcoin market. TechDev, known for his bullish views on Bitcoin, sees no reason to worry. He analyzed the new wallet addresses in relation to course behavior and shows here that the scenario from last year was by no means an isolated case. Back then, the number of new addresses made lower highs while the price made higher highs. "In 4 of the 6 corrections, there was divergence with price ma...

The 5 largest platforms for non-fungible token (NFT) collectibles

  Since the beginning of 2021, non-fungible tokens (NFT) have had no holding back and the sector is setting new records almost every day.  More and more artists, stars and brands are realizing the potential - NFT are well on their way to catapulting the crypto space into the mainstream.  But which collectibles are currently the most popular? What are NFT? NFT are unique tokens that cannot be exchanged one-for-one for an equivalent token.  Any asset that is tokenizable can be an NFT.  This includes, for example, (digital) works of art, trading cards, game items and crypto domains.  Theoretically, however, real estate or securities can also be mapped as NFT. NFTs can be used to transparently map ownership structures on a public blockchain.  This allows them to store value just like real objects, even if additional copies are easy to make.  For example, the original picture of the Mona Lisa is significantly more valuable than a photo, as everyone kno...
