Blockchain bridge explained
"Blockchain bridges work just like the bridges we know in the physical world. Just as a physical bridge connects two physical locations, a blockchain bridge connects two blockchain ecosystems. Bridges facilitate communication between blockchains through the transfer of information and assets." - Ethereum
Bridges offer a compatible and comprehensive way to securely interoperate – when a token is transferred from one blockchain to another, the token will be “wrapped” and converted to a token based on the target blockchain.
Types of blockchain bridges:
a. Unidirectional & bi-directional
Certain blockchain bridges are unidirectional bridges or one-way bridges. One-way bridges permits you to port assets only in one direction to the target blockchain, warranting no receiving of tokens.
Bi-directional, or two-way bridges, permit the user to freely convert assets to and from blockchains without transfer limitations.
b. Centralized & decentralized
There are also centralized and decentralized bridges. Centralized (also referred to as custodial or trusted bridges) warrants trust and a central authority regulating and operating the system and requires users to place trust and custody of their tokens in an operator for the transferring of tokens. Centralized bridges have trust assumptions concerning the custody of funds and security of the bridge, relying on the bridge operator’s credibility. This type of bridge relies on external verifiers that strays from the security protocols of the underlying blockchain, thus making it less crypto-economically secure.
Decentralized (also referred to as non-custodial or trustless bridges) place confidence and custody in the algorithm and smart contracts built into code. Decentralized bridges thus operate and delegate on the same underlying blockchain’s security protocols. The use of smart contracts put users fully in control of their funds - offering transparency to combat corruption or the abuse of power by operators (which could be the case in a centralized blockchain).
Why use a blockchain bridge
Bridges exist to connect blockchains, allowing the transfer of information and tokens between them.
- Blockchain bridges enable cross-chain interoperability
- Bridges on Telos offer a cost-effective and faster approach than what users may find on another native blockchain with high transaction fees and sluggish throughput.
- Bridges allow users to access new platforms and leverage the benefits of different chains
- Bridges fulfil the role of being multipurposed to facilitate the exchange of any type of data including smart contract calls, decentralized identifiers and off-chain information like stock market feeds.
- Bridges enable dApps to access the strengths of various blockchains – thus enhancing their capabilities (as protocols now have more design space for innovation).
- Through using bridges, developers from different blockchain ecosystems can collaborate and build new platforms.
Rubic is the Multi-Chain Swap Protocol which enables you to swap any of 15,000+ assets, on and between 12 blockchains in one click. Every day, 3+ million DeFi users waste hours and hundreds of dollars on fees to migrate between blockchains, switching between DEXs, and using bridges
Their protocol allows users to swap any token for any other token, on and between all blockchains, in one place — with a simple & intuitive UI
