A blockchain is a complete universe in itself as a blockchain owns its native currency & native Dex and community with many projects a unique payment system and everything a user needs each blockchain owns some unique features and projects.
There is no communication between different chains means assets of one chain cant to be transferred to another one to fix these problems bridges work as decentralized systems where user can convert their 1 chain assets into another chain.
Becareful
As many Blockcahisn are in the current market and users interact with them but hackers can easily find out loops and holes in chains and steel funds so use sustainable and Trusted Bridges should be used.
The market is growing we can expect a good future of the Bridges in 2022 to 2023 as a community is known for educating with multi assets and multi chains to grab opportunities and enjoy different features what they love
Unsafe means unsafe but still what to do in urgency i can see many decentralized Bridges as currently we to consider a chain offers more and extreme level is that means we need to select a chain by considering our requirements to proceed so on that chain we dont need any more bridges, as what you need is there already still you can consider bridges as a future platforms top be in trending as Crypto community is crazy
Where are decentralized Bridges?
Bridges are inherently centralized because Bridges are currently still managed by (trusted) centralized actors.
When we need interference between two Blockchains, a centralized entitiy is still involved, unfortunately.
We need real decentralized bridges!
