Decentralized finance (DeFi) noticed a document influx from centralized exchanges as crypto customers flocked to self-custody options following the FTX collapse. Over 100,000 Bitcoin (BTC) left crypto exchanges so buyers might keep away from third-party custody. True to the “not your keys, not your cash” mantra of Bitcoin, DeFi solves a big selection of issues related to centralized entities.
Nevertheless, a number of studies point out DeFi is just not a fail-safe surroundings, as high-profile protocol exploits like Wormhole, Nomad and Ronin made headlines in 2022 for the fallacious causes.
Supply: Token Terminal
DeFi exploiters significantly goal cross-chain bridges. In truth, cross-chain bridge exploits account for greater than half of all DeFi exploits since September 2020, with roughly $2.5 billion misplaced to those assaults. A Chainalysis report exhibits that token bridge assaults accounted for over 69% of the overall quantity of crypto stolen in 2022, a transparent indication that bridge exploits are on the rise.
Why do cross-chain bridges fail?
Because the DeFi ecosystem includes a number of blockchains, transferring digital belongings from one community to a different requires specifically designed protocols that work throughout completely different blockchains. Generally known as cross-chain bridges or token bridges, these protocols lock customers’ deposited tokens from one chain right into a contract, then subject the equal quantity of belongings to the identical consumer within the receiving community.
For instance, because the Bitcoin blockchain is just not instantly suitable with the Ethereum (ETH) blockchain, the DeFi ecosystem depends on workarounds like wrapped Bitcoin and token bridges to faucet into the liquidity out there within the Bitcoin ecosystem.
Most bridge protocols use central storage to again belongings on the receiving blockchain, making a goal spot for hackers. The shortage of developer experience in comparison with the advanced nature of making a bridge that works throughout a number of networks causes safety vulnerabilities, making cross-chain bridges the biggest assault floor of the DeFi house.
Tips on how to make DeFi extra strong
To make DeFi extra resilient to exploits, a brand new method removes this weak hyperlink between blockchains. Mintlayer is a layer-2 blockchain on the Bitcoin community that goals to attach its sidechain to the Bitcoin group with as little friction as doable. Customers can construct any kind of present DeFi utility on Mintlayer with out compromising the core fundamentals of safety and decentralization that the Bitcoin group is constructed on.
Mintlayer goals to eradicate token bridges, the biggest assault floor of DeFi, which prices customers billions of {dollars} yearly. As a substitute of wrapped tokens, customers can alternate their BTC for tokens on the Mintlayer blockchain by way of atomic swaps. By not requiring any kind of cross-chain bridges, wrapped tokens or pegging mechanism to make use of Bitcoin on its blockchain, Mintlayer eliminates the dangers related to bridges and third-party custody.
Talking concerning the launch of the Mintlayer blockchain, Mintlayer co-founder Enrico Rubboli stated that it took over 18 months of exhausting work. He added:
“Mintlayer is residence for tasks keen to construct on prime of Bitcoin. We’re thrilled by the standard and quantity of responses concerning potential tasks. Individuals need the performance of DeFi, however don’t wish to compromise the safety and ideas of Bitcoin.”
To allow customers entry to their BTC natively on the go, Mintlayer launched a cellular Bitcoin pockets, out there on each Google Play and the App Retailer.
DeFi ecosystem specializing in Bitcoin
Other than technical growth, the staff launched the Mintlayer Ecosystem Fund with the aim of constructing a Bitcoin-centric DeFi ecosystem. Initiatives can be part of incubator packages, accelerator packages and apply for grants, or apply for direct funding by means of the fund.
The collapse of main centralized organizations like Celsius, Terraform Labs and FTX triggered an exodus from centralized exchanges to decentralized finance and self-custody options in 2022.
If the DeFi ecosystem desires to maintain this new consumer base, it wants to unravel ongoing points related to the direct interplay between customers and blockchains, beginning with safety — its most important facet. Coming again full circle, the reply could lie in making the trail from Bitcoin to make use of in monetary functions as brief and straight as doable, with Mintlayer.
