As an example you reside in India and are touring to Singapore. In India, we use Indian Rupees (INR) whereas in Singapore they use Singapore {Dollars} (SGD). So you may convert some cash from INR to SGD utilizing a financial institution. Or you may use a world card that allows you to pay in SGD when you’re in Singapore. That is easy on the earth of banks however much more troublesome on the earth of blockchains.
Ethereum Mainnet and Terra are two unbiased blockchains. They’ve completely different guidelines and consensus mechanisms. The native token of Ethereum Mainnet is ETH whereas that of Terra is LUNA.
Now suppose that you’ve got a bunch of LUNA on Terra, however wish to apply it to the Ethereum Mainnet. How do you do this?
That is the place a blockchain bridge comes into the image. You might use the Terra Bridge to purchase Wrapped Luna (WLUNA) which is an ERC-20 token native to the Ethereum Mainnet.
In easy phrases, here is how a typical bridge works:
It receives one sort of crypto, as an illustration, LUNA. It locks this LUNA as a deposit. It ‘mints’ an equal quantity of one other cryptocurrency, like, Wrapped LUNA and releases it on one other blockchain e.g. Ethereum Mainnet.
Trusted Versus Trustless Bridges
A ‘Trusted Bridge’ relies upon upon a central entity and also you lose management of your cryptos if you use it.
A ‘Trustless Bridge’, alternatively, operates utilizing good contracts and also you stay accountable for your cryptocurrencies.
The Prime Ten Bridges
The highest bridges and their Whole Worth Locked (TVL) are:
WBTC (WBTC): $11.19 billion (roughly Rs. 86,067 crore)
Multichain (MULTI): $5.07 billion (roughly Rs. 38,995 crore)
Portal: $4.18 billion (roughly Rs. 32,149 crore)
hBTC (hBTC): $1.54 billion (roughly Rs. 11,844 crore)
JustCryptos (JST): $1.2 billion (roughly Rs. 9,229 crore)
Terra Bridge: $1.08 billion (roughly Rs. 8,305 crore)
RenVM (REN): $928.46 million (roughly Rs. 7,139 crore)
cBridge (CELR): $749.69 million (roughly Rs. 5,765 crore)
ChainPort: $207.42 million (roughly Rs. 1,595 crore)
Allbridge (ABR): $207.25 million (roughly Rs. 1,593 crore)

Hacking Bridges
As a result of bridges maintain a ton of crypto belongings, they’re juicy targets for hackers. And, as a result of writing the code for bridges is insanely advanced, hackers are having a subject day plundering them.
When a bridge will get attacked, the hacker withdraws crypto from one aspect of the bridge, e.g. Wrapped LUNA, with out depositing something on the opposite aspect e.g. LUNA.
One of many greatest crypto assaults came about in March 2022 when the Ronin bridge, constructed for Axie Infinity, was hacked for $625 million (roughly Rs. 4,729 crore) in ETH and USDC.
Ronin labored ‘off-chain’ — it interfaced with the blockchain however existed on exterior servers that weren’t part of the blockchain. It relied on 9 validator nodes, of which 5 nodes have been wanted to validate transactions. The hackers exploited code vulnerabilities and likewise used social engineering.
One other main Bridge hack focused Wormhole which helps six blockchains — Terra, Solana, Ethereum, Binance Sensible Chain, Avalanche, and Polygon. The price of the hack was $322 million (roughly Rs. 2,410 crore).
