Vitalik Buterin’s ominous DeFi Prophecy comes true

0 10

 

In recent months, so-called token bridges have become increasingly popular in Defi space. Well-known token bridges are, for example, Multichain (MULTI), Allbridge (ABR), THORChain (THOR), Synapse (SYN), or Wormhole. They enable tokens to be freely transferrable between different blockchains. The big advantage for many investors is that they can transfer their digital assets between a variety of blockchains without intermediaries. On the one hand, they can save on transaction costs. On the other hand, this opens up a multitude of possibilities for them to use different Defi protocols to earn interest.

For example, they can move their tokens between different blockchain networks at lightning speed to conduct arbitrage trading. In addition, the token bridges make it possible to exploit even more effectively short-term liquidity mining programs that are held on different blockchains to generate profits. For example, USDT Lending on Aave (Ethereum mainchain) earns just 2.1 percent annual interest, while USDT Lending on Polygon currently earns investors 10 percent annually thanks to liquidity mining rewards.

Token bridges thus make the Defi space a lot more efficient, as they offer investors the opportunity to move between blockchain networks with theoretically infinitely many income opportunities. The big disadvantage, however, is that many token bridges currently still have significant security deficiencies. Again and again, it happened in the past that they were victims of hacker attacks. For example, THORChain has been hacked multiple times and Poly Network made headlines around the world when a white hat hacker stole over $600 million.

Recently, there was another hack on the Token Bridge Wormhole, which lost around 320 million US dollars in the process. This incident comes as little surprise to Ethereum inventor Vitalik Buterin. In a Reddit post just a few weeks ago, the Ethereum mastermind warned the Defi community about the significant security risks of token bridges. In a made-up scenario, he described the vulnerabilities that token bridges would have and how they could be exploited by malicious actors. The Wormhole case has shown once again how real the risks of token bridges still are.

The well-known Defi expert “ChainLinkGod” nevertheless assumes that token bridges will play a decisive role.

Given that token bridges are an important part of the blockchain world, the goal should not be to prevent them but to make them more secure.

Buterin also believes in a multichain future, but still expects a few hacks to come this year.
