Everything You Should Know About Blockchain Bridges

Everything You Should Know About Blockchain Bridges ...

Let''s say you live in India and are traveling to Singapore. In India, we use Singapore Dollars (SGD) whereas in Singapore, you may convert money from INR to SGD using a bank. Or you might use an international card that allows you to pay in SGD when you are in Singapore. This is simple in the world of banks but also a lot more difficult in the world of blockchains.

The two independent blockchains, Ethereum Mainnet and Terra, are governed by different rules and consensus mechanisms. While Ethereum Mainnet''s native token is ETH, the second token of Terra is LUNA.

Now imagine that you have a bunch of LUNA on Terra, but you want to use it on Ethereum Mainnet. How do you do this?

The Terra Bridge will be used to purchase Wrapped Luna (WLUNA), an ERC-20 token native to the Ethereum Mainnet.

Here''s how a coutume bridge works: In simple terms, here''s how it works.

LUNA is a cryptocurrency that can be used as a deposit. It''mints'' an equal amount of another cryptocurrency, like the Wrapped LUNA, and releases it on another blockchain, e.g. Ethereum Mainnet.

Bridges that are trusted rather than trustless

When you use it, a ''Trusted Bridge'' depends on a central entity. You lose control of your cryptos.

On the other hand, a ''Trustless Bridge'' is operated with clever agreements, and you remain in charge of your cryptocurrency.

The Top Ten Bridges

The top bridges and their Total Value Locked (TVL) are:

$11.19 billion (roughly Rs. 86,067 crore) is the WBTC''s (WBTC).

Multichain (MULTI): $5.07 billion (roughly Rs. 38,995 crore)

Portal: $4.18 billion (roughly Rs. 32,149 crore)

$1.54 billion in hBTC (roughly Rs. 11,844 crore)

$1.2 billion (roughly Rs. 9,229 crore) is being used by JustCryptos (JST).

Terra Bridge: $1.08 billion (roughly Rs. 8,305 crore)

RenVM (REN): $928.46 million (roughly Rs. 7,139 crore)

$749.69 million (roughly Rs. 5,765 crore) has been issued by cBridge (CELR).

ChainPort: $207.42 million (about 1,595 crore)

$207.25 million from Allbridge (ABR) (about 1,593 crore)

Bridges on Hacking

Because bridges have a tumult of crypto assets, they are attractive targets for hackers. And because writing the code for bridges is hugely complicated, hackers are having a field day plundering them.

When a bridge is attacked, the hacker removes crypto from one side of the bridge, e.g. wrapped LUNA, without imposing anything on the other side, e.g. LUNA.

In March 2022, the Ronin bridge, built for Axie Infinity, was stolen for $625 million (roughly Rs. 4,729 crore) in ETH and USDC.

Ronin worked ''off-chain'' that it ties with the blockchain but existed on external servers that were not a part of the blockchain. It relyed on nine validator nodes, of whom five nodes were required to validate transactions. The hackers also used social engineering.

Another major Bridge hack targeted Wormhole, which supports six blockchains, Terra, Solana, Ethereum, Binance Smart Chain, Avalanche, and Polygon. The cost of the hack was $322 million (roughly Rs. 2,410 crore).
