Furthermore, the best bridges will be the most secure, interconnected, fast, capital-efficient, cost-effective, and censorship-resistant. These are the properties that need to be maximized if we want to realize the vision of an “internet of blockchains”. While bridges unlock innovation for the blockchain ecosystem, they also pose serious risks if teams cut corners with research & development. The Poly Network hack has demonstrated the potential economic magnitude of vulnerabilities & attacks, and I expect this to get worse before it gets better.
Bridges help blockchains propagate the ‘distributed ledgers’ beyond the local limits of a mesh network, creating seamless interconnections. Essentially, blockchain bridges aid in transferring data and digital assets between two blockchain networks, thereby enabling communication. Of course, both blockchains could have different protocols, smart contract rules, and governance structures, but the bridge allows both networks to communicate and share data safely. Blockchain bridges are systems that connect different blockchains and enable users to exchange one type of coin or token for another.

Trust-based bridges, also known as federated bridges, are centralized bridges that must be managed by a single entity or federation of mediators. The federated bridge functions similarly to a private or enterprise blockchain. As a result, users rely heavily on the operator to ensure the bridge’s safety and their funds.
The Ultimate Guide To Smart Contracts
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. First, a blockchain bridge reduces network traffic by distributing token processing across other, less congested blockchain networks. Additionally, a bridge makes the blockchains infinitely scalable by removing the consensus and different ecosystem-specific rules. A trusted or federated bridge runs similar to a private or permissioned blockchain. A central entity manages and oversees bridge transactions, and a set of criteria is established that an individual must meet to become part of the central federation.
However, all blockchains develop in isolated environments and have different rules and consensus mechanisms. This means they cannot natively communicate, and tokens cannot move freely between blockchains. But, what do you do if you want to make a similar exchange to use a different blockchain? Let’s say you want to exchange ETH on Ethereum Mainnet for ETH onArbitrum. Like the currency exchange we made for EUR, we need a mechanism to move our ETH from Ethereum to Arbitrum.
When transferring a large amount of cryptocurrency, trust-based bridges can be a quick and cost-effective option. However, it is critical to understand that the primary concern of the federation members is to keep transactions running. With the growing number of blockchain protocols, it is nearly impossible not to transfer assets between them. However, blockchain is limited to the boundaries of its domain due to a lack of interoperability. This means Dogecoins cannot be used to make a transaction on the Bitcoin blockchain. The finance industry has seen significant shifts over the past few years with the growing popularity of cryptocurrency.
Despite what individual communities believe, the reality is that the universe tends towards entropy, and the number of these networks will likely continue to increase into the future. Chain-specific is a blockchain bridge that typically handles simple operations such as locking and unlocking tokens in the source chain and knocking out any wrapped digital assets in the target chain. This bridge exists solely to provide access to a specific asset from a different network. These are frequently “wrapped” assets fully secured by the underlying assets held, whether custodian or non-custodian. Such bridges are the simplest to implement and serve as a flywheel for fluidity, though they have limited functionality and must be implemented in each target chain. However, a bridge mechanism is required to enable smart contract and data exchange, asset transfers, and other feedback between different blockchains.
This bridge provides an application that gives you access to two or more blockchains. Instead of having separate instances of the entire application blockchain, application-specific bridges have lighter and modular “adapters” on each blockchain. However, there is a network effect because the blockchain on which the adapter is implemented has access to everything else it is connected to.

Dapps to access the strengths of various blockchains – thus enhancing their capabilities . In the same way, the process is reversed to get your token back on blockchain A. Tokens from blockchain B are sent to the bridge, where they are burned and unlocked in blockchain A. The bridge blocks What is a Blockchain Bridge that amount of coin in blockchain A to send this token from A to B. It then mints the exact amount to send to the receiving address on blockchain B. Bridging in blockchain has a few steps that work in tandem to transmit information from the source blockchain to the destination blockchain.
In this case,Arbitrum has a native bridgethat can transfer ETH from Mainnet onto Arbitrum. To create the basic structure for this task, you need a bridge between Blockchain A and B. Bridges exist to connect blockchains, allowing the transfer of information and tokens between them. One recent hack was Solana’s Wormhole bridge, where 120k wETH ($325 million USD) was stolen during the hack.
Blockchain Bridges: Building Networks Of Cryptonetworks
However, trustless bridges can provide users with a greater sense of security and greater flexibility when moving cryptocurrency. This means trustless bridges allow users to keep control of their funds by utilizing smart contracts. Blockchain bridges are connections between two blockchain ecosystems. Just as a physical bridge connects two physical locations, a blockchain bridge integrates two different blockchain worlds running on similar or varying protocols. This connection allows the transfer of data and tokens between the ecosystems.
Liquidity networks shine with speed and security because they are locally verified systems (i.e. do not require global consensus). They are also more capital efficient than bonded/insured external validators because capital efficiency is tied to transaction flow/volume rather than security. For example, given somewhat equal flows between two chains and a built-in rebalancing mechanism, liquidity networks could facilitate an arbitrarily large amount of economic throughput. The trade-off is with statefulness because while they can pass around calldata, they are limited in functionality. External validators & federations generally excel with statefulness and connectivity because they could trigger transactions, store data, and allow interactions with that data on an arbitrary number of destination chains.
The Future Of Blockchain Bridges
You use the bridge to send a token from blockchain A to blockchain B, and you specify how many tokens you want to send. Token network fund with the thesis of embedding cryptoeconomic incentives into everything; transactions, computation, storage, prediction, power. Many bridging solutions adopt models between these two extremes with varying degrees of trustlessness. Manual checkpoints are similar to a trusted model as it depends upon a third party, i.e., the officials, for its operations. As a user, you trust the officials to make the right decisions and use your private information correctly. Users to access new platforms and leverage the benefits of different chains.
This is impossible to send directly because of the difference in the consensus protocol. However, with a bridge, the Ethereum wallet will receive a token “wrapped” by the blockchain bridge — converted to an Ethereum blockchain token. The Ethereum wallet will receive a “blockchain bridge” Solana token converted to an ERC-20 token. However, the receiving blockchains use a process known as “wrapping” to create compatible tokens to achieve this interoperability.
- Development platforms like Ethereum are already working towards making this a reality, creating tokenized applications like DeFi.
- You can use a bridge to transfer your ETH from Ethereum Mainnet to the alt L1.
- One recent hack was Solana’s Wormhole bridge, where 120k wETH ($325 million USD) was stolen during the hack.
- Agents are incentivized to ensure bridge transactions are correctly validated.
- Bridges are crucial to onboarding users onto Ethereum L2s, and even for users who want to explore different ecosystems.
- Let’s say you want to exchange ETH on Ethereum Mainnet for ETH onArbitrum.
- Because of this, liquidity networks like Connext are likely a safer option for users who are transferring large amounts of value.
DApps the biggest beneficiaries of blockchain bridges, accomplishing complex transactions in lesser hops and at a faster rate. Generalized blockchain bridge protocols are explicitly created to transport data across multiple blockchains. Hence, because a single project integration grants access to the entire ecosystem within the bridge, this design will have a significant network effect. However, this bridge has the disadvantage of sacrificing decentralization and security in favor of scalability.

The native cryptocurrency of the first blockchain is locked during this process, and a proportional amount of wrapped currency is minted on the second blockchain. When you need to transfer assets from one blockchain to another, you must use a bridge. This means a bridge is essentially an information exchanger between blockchains. Therefore, a bridge is a cryptocurrency revolution that allows for trading fluidity between blockchains.
While it is a highly fragmented and competitive landscape for bridge builders, teams should remain disciplined in prioritizing security over time-to-market. For Ethereum to scale and keep up with demand, it has required rollups. Alternatively, L1s like Solana and Avalanche are designed differently to enable higher throughput but at the cost of decentralization. Tokens are not transferred but are burned on the source blockchain and minted on the destination blockchain.
This comes at the cost of security, however, since users are, by definition, relying on the security of the bridge rather than the source or destination chains. While most external validators today are trusted models, some are collateralized, of which a subset is used to insure end-users. Unfortunately, their insurance mechanisms are often reflexive; if a protocol token is used as collateral, there is an assumption that the dollar value of that token will be high enough to make users whole. Furthermore, if the collateral asset is different from the insured asset, there is also a dependency on an oracle price feed, so the security of the bridge could degrade to the security of the oracle.
If not trusted, these bridges are also the least capital efficient because they need to scale collateral proportional with the economic throughput they are facilitating. Light clients & relays are also strong with statefulness because header relay systems could pass around any kind of data. They are also strong with security because they do not require additional trust assumptions, although there is a liveness assumption because a relayer is still required to transmit the information. These are also the most capital-efficient bridges because they do not require any capital lockup whatsoever.
As the number of blockchains protocols increases, so does the demand to move assets across chains. Blockchain bridges allow users to use and enjoy various blockchain technologies without switching platforms. Unlike https://xcritical.com/ the federated model, a trustless bridge is entirely decentralized and operates via a network of agents that are not centrally governed. Just like public blockchains, anyone can join the network as an agent.
Unlocking New Features And Use Cases For Users And Developers
Blockchain bridges function the same way physical bridges do –linking two places together. A blockchain bridge connects two blockchain ecosystems in the same way that a physical bridge connects two physical locations. Blockchain bridges have greatly improved blockchain performance and lessoned network congestion. Bridges are crucial for developers and users, enabling interoperability between different blockchain worlds. Future development for blockchain bridges will reduce the token verification overheads, move to the more secure ‘bonded’ and ‘insured’ models, and introduce bridge aggregators for a better user experience across the board.
Let’s say you want to own native Bitcoin , but you only have funds on Ethereum Mainnet. However, WBTC is an ERC-20 token native to the Ethereum network, which means it’s an Ethereum version of Bitcoin and not the original asset on the Bitcoin blockchain. To own native BTC, you would have to bridge your assets from Ethereum to Bitcoin using a bridge. Alternatively, you might own BTC and want to use it in Ethereum DeFi protocols. This would require bridging the other way, from BTC to WBTC which can then be used as an asset on Ethereum. For instance, suppose you want to send Solana tokens to an Ethereum wallet.
However, unless your funds are already on an exchange, it would involve multiple steps, and you’d likely be better off using a bridge. If you have ETH on Ethereum Mainnet and you want to explore an alt L1 to try out their native dapps. You can use a bridge to transfer your ETH from Ethereum Mainnet to the alt L1. For example, someone wants to exchange Bitcoin for Ethereum ETH. For this to happen, you will need an exchange that transforms Bitcoin into Ethereum.
Like most centralized operations, there are trust assumptions on the custody of the funds and the bridge’s security. Users make decisions based on the reputations of the bridge and do not control their assets. To create seamless integrations between these protocols so that assets can move between different chains without trouble, we need blockchain bridges. This article will look at crypto bridging, how blockchain bridges connect blockchain worlds, and why they are pivotal in building Web3. After years of research & development, we are finally in a multi-chain market structure. There are over 100 active public blockchains, many of which have their own unique applications, users, geographies, security models, and design trade-offs.
Blockchain bridges resolve scalability issues that popular blockchain networks like Ethereum often face, thus enabling instantaneous peer-to-peer transactions. Payments and settlements are not impacted by network congestion or traffic. Instead, workloads are transferred to lower congestion blockchains for instant processing.
