Hello all.
Previously I would like to convey to the contest organizers that I am a layman about Blockchain and Cryptocurrencies. But I want to try it not to miss the "Steemit Engagement Challenge Season 5 - Week 1" contest in this great community, This is my sixth participation here. But if everything I say here there are many mistakes. I hope input from all my friends here as motivation for me to learn more about these two things.

A little understanding that I have learned the past few days is about the introduction of the name Cryptocurrency.

Talking at length about blockchain turns out to require a lot of knowledge with digital currencies which we often call crypto assets. And it turns out that these crypto assets are secured by what is called blockchain technology so that their security from counterfeiting will continue to be maintained. That's what I understand from some of the sites I studied. I try to describe in my own language to eliminate my fear of plagiarism that will tarnish the good name of the platform and community with what I write here.

• What do you understand by blockchain bridge? And what requires a bridge on the blockchain.

One thing I can respond to about blockchain bridges is a tool for connecting transfers of assets from one type of coin to another. Blockchain bridge is a means of connecting the movement of a different digital asset. It can also be called a cross-chain bridge or Network bridge. This will serve to bridge the transaction process of one coin and another.

• What are the benefits of a blockchain bridge? How do bridges work?

In this case I will give an example is when you want to buy a STEEM coin asset using your Bitcoin coin asset. Processing the transaction is a blockchain bridge called the benefit of a blockchain bridge with a system of wrapping your BTC coin assets in the Bitcoin blockchain so that it becomes a Steem asset with a value equivalent to the value of the Bitcoin asset you use in the transaction. It debuts with how blockchain bridges work.

• Highlight blockchain bridge types by category. Choose an example of an existing blockchain bridge and explain how it works.

In some of the articles I have studied I have come across different types of blockchain bridges. Among them are Centralized bridges, Multi-chain blockchain bridges, Dapps dedicated Bridges, blockchain to blockchain bridges and Coin wrapped bridges.

Here I will highlight a blockchain bridge called a wrapped Blockchain bridge and how it works.

Difficult to explain in detail. Here I will explain it by giving an easy-to-understand example. If someone has a BTC coin asset with a value of 0.5 BTC which can only operate on the bitcoin blockchain network. So if you want to operate on the ETH network, you have to wrap it in a network called the ERC-20 protocol.

Then your BTC asset which is worth 0.5 BTC will become WBTC coin asset on the ERC-20 protocol network with a fixed asset value of 0.5 BTC even though the coin name is already in the form of WBTC. This means that the value is still full at 1:1 with the wrapped asset. In this case, the BTC coin asset can already operate on the ETh network with the full value, which is equivalent to 0.5 BTC. This will continue to be maintained by the token protocol in a wrapped way and will continue to be ours completely with WBTC coin assets but have a value equivalent to the previous BTC asset value.

• Are there any limitations on blockchain bridges? What do you think about the future of blockchain bridges?

Several cases of theft of crypto coin assets occur today. I don't understand if it's because of a problem with the Blockchain bridge. However, from the results of my study, I did not find any limitation of blockchain bridges with various types of blockchain bridges that have been created. So that this becomes a problem that causes losses that we need to raise as material for analysis.

Along with the development of Cryptocurrency, which is becoming a popular investment and has a good profile in the future. Blockchain bridges are also a necessity today and even more so in the future. So improvement should be a priority. Especially about good security so that it becomes something investors are expected about
