Introduction:

First of all, we should explain the origin of the requirement for bridges. One of the limitations of the blockchain world is the lack of communication between the two different blockchain networks. This huge constraint has become the impetus for the creation of a solution called the Cross-Chain Bridge. This creates a platform for individuals to transfer the equivalent of their assets to target blockchain without selling their assets on main blockchain.

A Wormhole bridge is a solution to transfer assets between a root chain and several destination chains. The Wormhole does this with the help of intermediaries called Guardians. This bridge has a Smart Contract. One of the important points when evaluating the centralized or decentralized connection of this bridge is to examine how the Admin Key of this smart contract is maintained in the blockchain networks. The Wormhole bridge is a decentralized communication bridge. This smart contract is managed and controlled by network nodes.

Comparison with Terra-shuttle:

Shuttle bridge is the main tool of Terra network to transfer cryptocurrencies from Terra ecosystem to other blockchains and vice versa. The Wormhole bridge and Shuttle bridge are compared from different aspects.

The addresses of these two bridges are listed as:

Shuttle bridge: https://bridge.terra.money/

Wormhole bridge: https://portalbridge.com/#/transfer

According to my experiences, the Shuttle bridge only transfer Terra based assets but Wormhole bridge makes it possible to transfer cryptocurrencies from various blockchains to different ones.

The advantages and disadvantages of Wormhole bridge in comparison with Shuttle bridge are presented in the following parts.

The user interface of Wormhole and Shuttle bridges are demonstrated in the following images.

Advantages:

• In my opinion, the main advantage of Wormhole bridge over Shuttle is the diversity of main and target blockchains.

The wormhole bridge supports Solana, Terra, Polygon, Ethereum, Binance smart chain, Avalanche and Oasis.

However, Shuttle bridge supports Terra, Ethereum, Binance smart chain and harmony.

• One of the most significant part of the Wormhole bridge is the lower transaction fee in comparison with Shuttle bridge.

• The transaction speed of Wormhole bridge is higher than Shuttle bridge.

• The Wormhole bridge supports NFTs which is very essential point in the nowadays crypto world.

• The succeed rate for transactions through Wormhole bridge is satisfactory.

Important:

Before using the Wormhole Bridge, make sure that the token you intend to transfer from the main blockchain to the target network is secured in the liquidity pools of the target blockchain protocols.

Recomandations:

• The interface of Wormhole bridge and user friendliness could be improved in my opinion.

• The token cover should be progressed and more tokens should be added to this bridge.

Conclusion:

For a final words, Wormhole is a project that seeks to build a bridge between several blockchains. Using the Wormhole Bridge, the chosen coins and tokens can be converted to their rapid tokens in the target network. The Bridge has benefits like, the high transaction speed as well as the low transaction fee in comparison with Shuttle bridge.
