What is a Blockchain Bridge & How do They Work?

Bridges may generally be classified according to their functions and mechanisms. Ethereum is the dominant blockchain for supporting decentralised applications, particularly in the sector known as DEFI – decentralised finance. DEFI includes a whole range of financial services for crypto users, such as lending/borrowing and swapping. Given the problem of blockchain interoperability a significant proportion of the value within the crypto system is locked out of Ethereum-based DEFI applications. Blockchain bridges are technical solutions for transferring data back and forth between two blockchains.

What is the Need for Blockchain Bridges

Considering that assets from one blockchain are usually incompatible with foreign blockchains, the bridge is actually an asset of another blockchain. For example, if you want to bring bitcoin to the Ethereum blockchain for consumption, the bridge will wrap bitcoin in a blank code to make it compatible with the target blockchain. In the case of Ethereum, the bridge just turns bitcoin token into ERC-20 t token — Ethereum’s native replaceable token — which makes it usable like Ethereum’s native token. Polkadot is one of the most innovative blockchain bridges today, and also offers the DOT token. PrimeXBT offers long and short positions on DOTUSD, so traders can speculate on price action and potentially profit from the rapid proliferation of blockchain bridges in the future. Again, using the smartphone and email examples, anyone can see why connecting such ecosystems digitally is critical to mass adoption.

What’s the Future of Blockchain Bridges?

Blockchain technology, especially bridging, is still at an early stage of development, so of course there will be some concerns. Most of finance exists in those big cities, but beyond their borders all kinds of business exists. It is decentralized and insured by design, offering a unified standard for cross-chain transfers. It also integrates easily within any existing application, and is ready for NFTs and the Metaverse. The full power of email would never be realized, as it would segregate communities and users onto specific platforms.

  • Users can move tokens between networks using the token bridge dapp with the Nifty wallet or Metamask with a custom network setup.
  • What they did care about was security and making certain the blockchain wasn’t able to be hacked, compromised, and the assets and value stored there would also be safe.
  • Ethereum, Binance bridge, Avalanche, and Polygon PoS are some of the most famous bridges available.
  • Blockchain bridges introduce interoperability into current blockchain technology to create a more cohesive and interconnected community of users.
  • An effective cross-chain bridge can also enable the transfer of smart contracts and NFTs from one blockchain environment to another.
  • There are a lot of cool things a blockchain bridge can do, including converting smart contracts and sending data, but token transfers are the most common use.
  • In the case of trusted bridges, control is in the hands of a single entity or a small group of users.

Being able to work and move assets across networks will be a driving force in the digital world, from cryptocurrency networks to Metaverse platforms. So you might be wondering how blockchain bridges actually manage to send assets across incompatible blockchains. Since users need to lock their assets into smart contracts as part of their usage, the individual protocols hold enormous amounts of value. The actual costs depend on different factors such as whether the service is centralized or decentralized and on the blockchains involved. Transaction fees are usually paid in the same token that is transferred.

Blockchain Bridges by Functions

However, depending on the platform, this can be quite time-consuming and costly in terms of fees, especially if you need to do it frequently. Formerly known as Fantom Anyswap, Multichain positions itself as a cross-chain router protocol, enabling the flow of data and assets across different blockchain networks. No other cross-chain bridge service supports as many token types as Multichain.

This prevents assets and users from being shared from one ecosystem to another. Blockchain bridges are the key to eliminating the disadvantages of blockchain. In addition, Polkadot can connect external blockchain networks to create an even broader network of blockchains.

Advantages of blockchain bridges

Solana has huge appeal as a layer one chain given the significant throughput it can achieve, with 50,000 transactions per second, compared to Ethereum with just 30. As Solana and its ecosystem have developed the need for bridges quickly emerged. As challengers to Bitcoin and Ethereum have emerged so have solutions to bridge between the growing number of layer 1 chains.

RSK bridge contracts are upgradeable, ensuring a smoother move to the decentralized bridge in the future. Users can move tokens between networks using the token bridge dapp with the Nifty wallet or Metamask with a custom network setup. Today, Bitcoin and other cryptocurrencies dominate the discussion in finance and on Wall Street, but what makes these emerging assets so valuable is the blockchain network they support. As one of the most popular solutions to bridging blockchains is to require some level of trust this naturally brings the disadvantages of a single central point of control. Blockchain bridges encourage users to venture outside the domain of the particular assets they hold. So someone holding only ERC20 tokens can still experiment with dApps on Solana or Polkadot, using a bridge, which creates a greater diversity of experience.

The growth of new blockchain networks focused on ensuring combined benefits of decentralization, scalability and security. Therefore, you can notice the massive walls between different blockchain networks and ecosystems, which establish the urgency for blockchain bridges to dictate the future of the blockchain landscape. Blockchain technology has covered quite an extensive journey since its introduction to the world in 2008 with the Bitcoin whitepaper. The subsequent rise in the number of cryptocurrencies and development of blockchain networks with programmability, such as Ethereum, have created a completely new ecosystem.

Blockchain networks deploy different fragments of code to help developers in deploying applications, tokens and smart contracts over a network. In addition, all blockchain networks feature their own token standard and framework, offering opportunities for development. The expansion of blockchain projects, such as in the DeFi landscape, creates the necessity for bridges. As the number of projects in DeFi would continue increasing in the future, users will need interoperability of assets among different networks.
