WEEE

This year’s International E-Waste Day will focus on critical raw materials, the elements essential to the economy that have a high risk of supply disruption and limited substitutes.

Taking place on 14 October 2025, the 8th edition of International E-Waste Day will focus on highlighting how critical raw materials (CRMs) can be recovered from unused or broken electronic products.

A study by WEEE Forum and UNITAR showed that households own an average of 74 EEE items – excluding lamps and luminaires – of which 61 items are in use, nine are hoarded but working, and four are hoarded and not working.

The total mass of items in households is 90 million tonnes (Mt) of which 7 Mt is hoarded and working, and 3 Mt is hoarded and broken, according to the study.

Research published by Material Focus last year, found UK households are hoarding 880 million unused electrical items, and throwing away 103,000 tonnes of electricals annually.

The research, ‘Electrical Waste: Challenges and Opportunities’, found that the materials contained inside these “lost electricals” are worth £927 million.

By returning electrical items through official collection channels, consumers play a role in keeping critical resources in the loop and supporting the circular economy.

International E-Waste Day organisers will provide guidance, tools, and local events to help people make informed choices and dispose of their electricals in a way that allows CRMs to be recovered.

MUD Jeans

Host of the Festival of Circular Economy 2025 and owner of sustainable innovation studio Ape, Mark Shayler, explains why a circular future has arrived by examining two successful circular economy businesses.

The future is circular we hear – and it is. It offers a vital shift in how we manage resources and stimulate economic growth, especially at a time when resource scarcity is becoming more pressing.

Globally we currently wastes more than 90% of the materials we extract, all that circularity attempts to do is to stop the economy leaking.

The circular model reduces our dependence on finite resources, helping to mitigate the economic risks associated with supply shortages and price volatility.

For instance, transitioning to a circular economy could unlock up to $4.5 trillion in economic benefits by 2030.

This approach not only supports environmental sustainability but also offers economic opportunities by enhancing innovation, reducing waste management costs, and creating new markets for recycled materials.

Let’s take a look at a couple of inspiring organisations who have developed successful circular economy businesses, brought them to market, and are now scaling them.

Toast Brewing – Brewing Beer with Surplus Bread (UK)

Toast Brewing

Toast Brewing uses surplus bread to brew beer, exemplifying the circular economy by turning food waste into a product.

Founded in the UK in 2015, Toast partners with bakeries to collect unsold bread to replace a portion of barley in the brewing process.

The results is an award-winning craft beer that not only reduces waste but also lowers raw material costs – using 25% less barley than typical brews.

Notably, all profits from Toast are donated to charities fixing the food system, aligning economic success with social impact.

This innovative business model demonstrates how a business can generate revenue and tackle waste simultaneously using a circular economy approach.

Key impacts in the last five years include:

  • Waste Diversion: Saved over 3.3 million slices of surplus bread from going to waste since they began brewing in 2016, which saved bakeries disposal costs and created value from a would-be waste stream.
  • Resource Savings: By using surplus bread, Toast also avoided 5.3 tCO2e in emissions.
  • Economic & Social Impact: Toast donated £116,000 (as of 2024) to food waste charities.

It’s also important to make a great beer not just a waste beer, Toast Brewing has won numerous taste awards and is a firm favourite in our house.

Toast has built a viable brand carried by major retailers, and has a growing customer base of ‘planet-friendly’ beer drinkers and a small but passionate team, proving the approach makes business sense.

MUD Jeans – Leasing Denim for Circular Fashion

Mud Jeans

MUD Jeans is a Dutch denim brand pioneering a lease model to keep jeans in circulation for longer.

The company’s trademark ‘Lease A Jeans’ programme lets customers rent jeans for a monthly fee instead of buying them outright​.

This service-based model ensures MUD Jeans retains ownership of raw materials, enabling efficient recycling and waste reduction, but also quality.

It also fosters strong customer loyalty (free repairs are provided during the lease) and a steady revenue stream.

Over the past five years, the company has successfully scaled this model while maintaining a focus on sustainability and fair labour.

Key outcomes include:

Overall, the company reports a 42% year-on-year reduction in its corporate carbon emissions in 2022​. By using up to 40% post-consumer recycled cotton in each product, MUD Jeans also diverts textile waste and reduces demand for virgin cotton.

Celebrating the circular economy in action

What I love about these two examples is that they are centred around great products first-and-foremost. You would buy them because the products are great rather than circular.

They prove that circular economy principles – from product design to end-of-life recovery – can enhance profitability, innovation, and positive impact in parallel.

As more companies adopt such models, we move closer to a regenerative, waste-free future and at the same time show how rethinking the lifecycle of products can create economic value.

So put on your jeans and grab a beer (zero ABV available too).

Food redistribution

The UK Government has announced grants totalling £13.6 million have been offered to 12 food redistribution charities across England.

The Department for Environment, Food & Rural Affairs (Defra) says the grants will help redistribute an estimated 19,000 tonnes of food from farms to homeless shelters, food banks and charities.

Commenting on the grants, Waste Minister Mary Creagh, who is also responsible for the circular economy, said: “This government’s Plan for Change is acting on food poverty and tackling Britain’s throwaway culture, ensuring more good food ends up on plates and not in bins.

“I am delighted to see this support go to 12 outstanding redistribution charities to form closer relationships with our hard-working farmers, and ensure their good food goes to those in need.”

Successful redistribution organisations that applied for funding through the grants include City Harvest, a food charity which rescues surplus food and delivers it to more than 130,000 people a week, which will receive more than £303,000.

Sarah Calcutt, CEO of City Harvest, commented: “This new funding will allow us to increase the amount of food we pick up directly from farms, reduce farm costs and increase further the amount of fresh food we can offer our customers.”

A consortium bid led by FareShare UK and its network partners, including Felix Project, will receive more than £9.2 million.

Food in Community, based in Devon, will also receive more than £1.5 million to partner with local farmers and food producers to redistribute surplus food.

These Government grants will go a long way to supercharge more charitable networks to capture some of the estimated 330,000 tonnes of food that could be redistributed from UK farms every year

Last year, the UK Government established an independent Circular Economy Taskforce to develop a Circular Economy Strategy.

The Taskforce is focusing on five priority sectors, including agri-food, the built environment, chemicals and plastics, transport, and electronics.

The UK Government also reaffirmed its continued support for the UK Food and Drink Pact, managed by WRAP, which looks to deliver a more sustainable supply chain and reduce food waste in the home.

Catherine David, CEO of WRAP, said: “Food waste happens wherever food is grown, made, sold and consumed – from farm to fork.

“Redistributing surplus food from retail and manufacture is a real success story, stopping thousands of tonnes of good food from going to waste every year.

“These government grants will go a long way to supercharge more charitable networks to capture some of the estimated 330,000 tonnes of food that could be redistributed from UK farms every year – and use it for good – in communities around the country.”

Commenting on the grants, David Gudgeon, Head of External Affairs at Reconomy Connect, a brand by international circular economy specialists Reconomy, said: “We’re very pleased to see Defra tackling food waste through these grants, which rightly prioritise redistribution in line with the food waste hierarchy and ensure that high-quality, surplus food is used to feed people first.

“Initiatives like this not only offer vital support to families facing food insecurity, but also help to retain the highest possible value from our food system, preventing fresh, nutritious produce from going to waste unnecessarily.”

Ireland

The Irish Government announces over €27 million in funding to support a wide range of initiatives aimed at advancing Ireland’s transition to a circular economy.

The €27 million in funding comes from the Circular Economy Fund, which is financed through environmental levies on plastic bags, landfill, and waste recovery.

Minister for Climate, Energy, and the Environment Darragh O’Brien and Minister of State with responsibility for the Circular Economy, Alan Dillon, announced the new funding.

Welcoming the announcement, Minister O’Brien said: “This year’s circular economy funding continues to advance initiatives that rethink waste, restore and protect environmental balance and empower communities to shape climate solutions.

“We are proud to support these initiatives as we endeavour to build a more resilient future for all.”

This funding represents a significant investment in Ireland’s sustainable future.

The Department of Climate, Energy, and the Environment states that the annual allocation will support local authorities, community groups, and organisations across Ireland in implementing projects that reduce waste, extend the life of materials, and promote sustainable resource use.

Speaking at the announcement, Minister of State Dillon said: “This funding represents a significant investment in Ireland’s sustainable future.

“By supporting circular economy initiatives, we are not only reducing waste and protecting our environment but also fostering innovation and creating green jobs.

“The projects funded through this allocation will serve as powerful examples of how communities and businesses can lead the way in building a more resilient, resource-efficient Ireland.”

CIWM (The Chartered Institution of Wastes Management) Ireland Centre Chair, Enda Kiernan, welcomed the announcement.

Kiernan said: “The fund is intended to support communities to make a move from the traditional linear ‘take-make-use-dispose’ model towards a ‘circular economy’ where resources are reused or recycled as much as possible, waste generation is minimised, and towards more sustainable practices that prioritise reuse, repair, and recycling.”

The world of blockchain is growing at a consistent pace with innovative technologies and applications grabbing headlines now and then. Cross-chain bridges are one of the most effective technological advancements in the crypto landscape that have solved a critical problem. The Synapse Bridge crypto utility is a standout offering by Synapse and can be a frontrunner for achieving cross-chain interoperability. As the domain of blockchain focuses more on DeFi, NFTs, and web3 technologies, interoperability serves as a major influence on the growth and adoption of blockchain. Let us learn more about the Synapse Bridge and its distinctive features.

Build your identity as a certified blockchain expert with 101 Blockchains’ Blockchain Certifications designed to provide enhanced career prospects.

Understanding the Fundamentals of Synapse Bridge

Synapse is one of the innovative projects aimed at capitalizing on the need for cross-chain bridges. Cross-chain bridges connect different ecosystems and allow users to experience the crypto landscape without barriers of accessibility. The most common answers for queries like “What is a Synapse bridge?” focus on its identity as a blockchain bridge. It is also important to ask about the factors that make it one of the most effective picks to solve interoperability issues.

Synapse has come up with a comprehensive cross-chain messaging system that serves as a crucial differentiator. Developers can leverage the messaging capability to create cross-chain dApps, which can make the most of the features of different blockchain protocols. The Synapse Bridge uses the innovative messaging infrastructure to ensure seamless transfer of assets throughout an ecosystem of supported networks. 

How Does the Synapse Bridge Work?

The Synapse Bridge offers a combination of bridging methods to ensure effective optimization of transactions. The cross-chain bridge also stands out for its compatibility with EVM and non-EVM blockchain protocols. As a result, it allows cross-chain transfers and swaps for a wide range of tokens. The Synapse protocol uses liquidity-based bridging, RFQ bridging, and canonical token bridging in its blockchain bridge. Each method offers a distinct advantage, thereby making Synapse Bridge one of the top cross-chain bridges that you should use.

Synapse Bridge offers canonical token bridging that enables seamless transfer of wrapped assets across networks. The liquidity-based bridging method leverages cross-chain swap pools that offer stability and efficient transfer of native tokens to different chains. On top of it, the RFQ or Request for Quote bridging feature optimizes the bridging process by identifying the ideal routes for faster and cost-effective transactions. The hybrid approach adopted by Synapse Bridge offers better functionality than other cross-chain bridges.

Enhanced Focus on Security 

One of the notable risks associated with blockchain bridges is the list of potential security vulnerabilities. Can you use the Synapse Bridge Metamask integration without any threats? Synapse has embraced a comprehensive security model to ensure the integrity of cross-chain asset transfers. The most striking highlight of the Synapse Bridge is the optimistic security model, which assumes that all transactions are valid. You might wonder about the effectiveness of a security model that allows every transaction to pass through.

Synapse brings in the next element in its security model to play, the off-chain actors and fraud proofs. Off-chain actors monitor the transactions and could submit proof of fraud within a specific timeframe to avert malicious transactions. The biggest strength of the security model of Synapse Bridge is the single honest verifier who identifies malicious behavior. 

Interestingly, the single honest participant is not the only one contributing to integrity of transactions on the Synapse Bridge. The cross-chain bridge also relies on collaboration between different roles, such as guards, notaries, executors, and broadcasters for validation of cross-chain transactions. Furthermore, Synapse also maintains commitment to security through governance, slashing mechanisms, and audits, which strengthen its security model.

Governance Model for the Synapse Bridge

The next critical concern associated with cross-chain bridges is the risk of centralization. As a matter of fact, critics state that cross-chain bridges entrust the power in one specific platform to take care of your asset transfers. Who is in charge of making decisions about how the platform will operate? The Synapse protocol bridge also has to face such questions that challenge its transparency and decentralization. Synapse offers a promising solution to this challenge in the form of Cortex DAO, the latest updated version of its governance system.

The members of Cortex DAO who hold more than 550,000 native CX tokens become eligible to submit proposals. DAO members can exercise their vote on multiple chains with CX or use the option of delegating votes to other token owners. The native token of Synapse, SYN, can be converted into CX tokens in the conversion portal offered by the protocol. 

The components of Cortex DAO that make it an effective solution for the governance of Synapse include Forum, Discord, and Snapshot. Forum offers a useful platform for posting and discussing about proposals before passing them for a vote. The Synapse protocol leverages Discord to encourage community discussion on general matters related to the protocol. Synapse also uses Snapshot to ensure decentralized voting on governance proposals that reach the voting stage.

Certified Enterprise Blockchain Professional Certification

Exploring the Synapse Bridge SDK 

Developers can use the Synapse Bridge SDK to integrate cross-chain token transfers in their applications. It also serves as a valuable tool for adding cross-chain liquidity transfer feature in various applications. You can use the Bridge SDK on the client side and server side for different use cases. The SDK helps in integrating a front-end application with Synapse Bridge or cross-chain arbitrage features in an application. Another use case of the Synapse Bridge SDK is the integration of Synapse JavaScript SDK with non-JavaScript applications.

The general discussions about Synapse Bridge crypto service miss one of the notable elements in the Bridge SDK. Synapse REST API is another powerful tool for developers as it facilitates integration of Synapse liquidity network in your applications. Developers can use HTTP requests to ensure dynamic integration of Synapse cross-chain liquidity and token transfers in different applications. The read-only REST API also helps in retrieving quotes and generating relevant call data for Synapse Bridge transactions.

How Does Synapse Bridge Perform Against Competitors?

Synapse Bridge has a lot of competitors who have been in this space, with some of them being pioneers of cross-chain interoperability. However, the crypto space always rewards innovation, and the same has happened in the case of Synapse. Their cross-chain bridge has an edge over other blockchain bridges with additional emphasis on security and decentralized governance. 

The Synapse Protocol Bridge has accommodated a wide range of tokens and blockchain networks under its umbrella. It features optimized bridging to ensure that you find the best path to transfer assets between networks. The primary goals of optimizing the bridging process include speed and cost efficiency. On top of it, the bridge service has been adopted in large numbers, registering significant growth in transaction volume.

Enroll now in the Blockchain Scalability and Interoperability Mastery Course to learn the skills needed to develop faster, scalable, robust, and interoperable dApps.

Final Thoughts 

The introduction to Synapse Bridge reveals a lot about the innovative efforts made by Synapse. It follows a hybrid approach to bridging, thereby achieving better speed and cost-effectiveness in cross-chain asset and liquidity transfers. The optimistic security model used in the Synapse Protocol provides the guarantee of secure cross-chain asset transfer and communication. The design of Synapse and recent advancements like the transition to Cortex DAO, address the risks associated with traditional cross-chain bridges. While Synapse has the potential to emerge as one of the biggest players in the crypto space, future trends and evolution of the protocol will determine its fate.

Every transaction on the Bitcoin blockchain stays there for eternity, without the fear of anyone modifying the transaction details. The capability of Bitcoin blockchain to revolutionize money is obviously one of its biggest strengths. You must also know about a unique opcode, OP_RETURN in Bitcoin, to understand how Bitcoin can store arbitrary data.

It is important to note that storing arbitrary data is not about saving your family photos on the Bitcoin blockchain. On the contrary, it focuses on embedding small and immutable chunks of information that open the doors to create multiple innovative applications. Let us learn more about the “OP_RETURN” opcode and its utility in the Bitcoin blockchain.

Exploring Bitcoin Beyond the Crypto Transactions

The first introduction to Bitcoin painted it as a decentralized electronic cash system. With the help of blockchain technology, the blocks of Bitcoin network record every transaction on the ledger. At the same time, the distinctive traits of Bitcoin blockchain such as decentralization, public verification and tamper-proof nature attracted developers. The attention of developers on Bitcoin blockchain created new avenues for using Bitcoin for something more than virtual currency. 

The thought of storing data on blockchain emerged for the first time as developers discovered that the Bitcoin ledger can store non-financial data. However, early attempts to store data on Bitcoin were inefficient and resulted in various issues. For instance, storing unspendable addresses created blockchain bloat since all the nodes have to track the unspendable outputs. It resulted in expansion of the size of Unspent Transaction Output or UTXO set, which requires more memory for operation of the nodes.

How Does OP_RETURN Help in Storing Arbitrary Data?

The need for data embedding alongside addressing the concerns of blockchain bloat led to the arrival of OP_RETURN. The Bitcoin developer community introduced the “OP_RETURN” opcode in 2014. You can review answers to “What is OP_RETURN in Bitcoin?” and discover that it is just a special script opcode for adding arbitrary data to the output of a transaction. One of the distinctive highlights of “OP_RETURN” outputs is that they cannot be spent. Any Bitcoin tokens linked to an “OP_RETURN” output will be burned and the UTXO set does not need to track the output. As a result, the opcode ensures a more efficient approach with reduced overheads for data storage on blockchain.

You can notice that making “OP_RETURN” outputs unspendable is an effective design choice. Since “OP_RETURN” transactions are not included in the UTXO set, they don’t consume memory of the full nodes. The unique design choice addresses the concerns of ‘blockchain bloat’ by supporting limited data storage without affecting the decentralization and efficiency of the network.

Workflow of OP_RETURN

The most crucial highlight in any guide on ‘OP_RETURN’ is its working mechanism. You can use a Bitcoin OP_RETURN example transaction to understand how the special opcode works. The standard Bitcoin transaction involves the output specifying the address of the recipient and the amount of Bitcoin you want to send. The ‘OP_RETURN’ opcode ensures that Bitcoin transactions can have an output which will not receive any Bitcoins. In addition, the transaction also includes a script featuring the “OP_RETURN” opcode accompanied with arbitrary data.

Here is a breakdown of the individual steps in the working of ‘OP_RETURN’ opcode.

  • The first step begins when a user initiates a Bitcoin transaction. 
  • In the second step, you have to add a special output i.e. the OP_RETURN output, which has a zero value. 
  • You will note that the locking script or scriptPubKey of the zero-value output starts with ‘OP_RETURN’ and then includes the desired data pushed on it. The pushed data is generally a hexadecimal code for the arbitrary information that you want to store.
  • Once the data embedding is complete, the transaction will be broadcast across the Bitcoin network. Miners will add the transaction to a block when it complies with the consensus rules and mempool policies. 
  • After confirmation of a transaction in a block, the embedded data will become an immutable component of the Bitcoin blockchain.

Discovering New Use Cases of Bitcoin with OP_RETURN

With the introduction of OP_RETURN in blockchain, you can find a wide array of applications that can transform Bitcoin into a trusted platform for data-anchoring services. The following use cases of OP_RETURN prove why it is an innovative advancement for the Bitcoin blockchain.

  • Decentralized Apps and Layer-2 Protocols

The utility of ‘OP_RETURN’ in Bitcoin blockchain is seen in the fact that it helps in anchoring data from different layer-2 protocols and decentralized apps. Sidechains or state channel networks can leverage ‘OP_RETURN’ to embed a summary of the off-chain state on the Bitcoin blockchain. It will help in supporting scaling solutions that need occasional interactions with the main blockchain to achieve better integrity and security.

  • Asset Issuance and Colored Coins 

Prior to the arrival of advanced token standards, OP_RETURN served as a primary factor for encouraging the development of ‘Colored Coins’. The opcode helped in coloring specific Satoshis or the smallest units of Bitcoin with metadata for representing other assets like shares in digital collectibles or shares in an organization. It helped in tracking and transferring ‘colored’ assets on Bitcoin, which served as a blueprint for tokenization. 

  • Proof of Existence 

The earliest example of applying OP_RETURN in Bitcoin is evident in timestamping of documents and digital files. The process involved taking a cryptographic hash of a document and embedding the hash in the OP_RETURN output. It ensures that you can prove the existence of the specific document at a particular point of time. The OP_RETURN opcode serves a significant role in safeguarding intellectual property rights and documentation of legal agreements.

  • NFTs and Digital Collectibles

The OP_RETURN opcode has a limited data capacity and many would think twice about its usability for NFTs and digital collectibles. The workflow of ‘OP_RETURN’ involves data embedding, which paved the path for introducing more sophisticated approaches to represent digital collectibles. You can notice how ‘OP_RETURN’ is a vital tool for promoting the rise of Bitcoin Ordinals and BRC-20 tokens which require larger storage. Future developments on Bitcoin blockchain, like Runes, might use ‘OP_RETURN’ in their protocol and BRC-20 tokens can shift to ‘OP_RETURN’ after limit removal.

Limitations of OP_RETURN

The different ways to use OP_RETURN for storing data on blockchain prove that it is an innovative advancement for Bitcoin. On the other hand, you must also know that the opcode has some limitations that have been subject to debates within the Bitcoin community. You should keep an eye on the following limitations of ‘OP_RETURN’ to make the best use of it.

  • Limited Data Size

The first aspect that you notice in the setbacks of the Bitcoin opcode for arbitrary data storage is the data size limit. OP_RETURN has an extremely small data size limit, 80 bytes, which restricts the amount and type of information that you can embed directly in the output. The limitation is in place for preventing excessive growth of the network and maintaining the network efficiency.

  • No Direct Utility 

While the concept of storing non-financial data on Bitcoin with OP_RETURN seems interesting, it does not qualify as a valuable utility. The data embedded in ‘OP_RETURN’ output does not have any significance for the Bitcoin protocol. The utility of ‘OP_RETURN’ depends largely on the external applications which interpret the data.

  • Burden of Additional Costs

One of the prominent highlights in answers to “What is OP_RETURN in Bitcoin?” focuses on the fact that OP_RETURN outputs have null value. However, the transactions will still impose the burden of fees according to their size. Imagine storing data in small chunks that adds up to the transaction size. For a network like Bitcoin, increased transaction size automatically translates to higher costs that you have to pay to miners.

Future Direction for OP_RETURN and Data Storage on Bitcoin

The prospects for storing arbitrary non-financial data on Bitcoin blockchain herald the beginning of a series of innovative advancements. The OP_RETURN opcode can become a focal point for innovation, as evident from its utility. For instance, OP_RETURN will emerge as a formidable driver for expanding the extensive data capabilities of Bitcoin. However, the adoption of OP_RETURN will depend a lot on whether the size limit will be reduced. The impact of OP_RETURN on expected advancements like Runes will help in reducing dependence on more complex data embedding techniques. 

Final Thoughts 

The uses of OP_RETURN in blockchain data storage prove that it is an advancement way ahead of its time. OP_RETURN emerged as a solution to blockchain bloat that resulted from ineffective data storage methods. Over the course of time, the opcode has evolved with diverse applications such as anchoring layer-2 protocols or timestamping documents. One of the biggest highlights of OP_RETURN is their adoption in emerging solutions like BRC-20 tokens and Bitcoin Ordinals. The limited data capacity of OP_RETURN is one of the biggest obstacles for its large-scale adoption. However, it will have a significant role in the future of Bitcoin by helping preserve its core identity while encouraging innovation.

Decoding the Importance of Blockchain Bridges

Interoperability might not appear like a big problem for the blockchain and crypto ecosystem when you see big players performing well. The lack of interoperability creates a massive barrier to accessibility as users on one blockchain could not interact with another network. In the long run, this problem may lead to reduced adoption rates and threats to growth of blockchain technology. 

The arrival of multichain bridges in crypto has been possible due to the efforts of some pioneers who recognized the interoperability problem. Crypto bridges helped in overcoming the isolated nature of blockchain networks and opened new avenues for collaboration. The utility of blockchain bridges ensures easier access to decentralized applications in different networks and seamless cross-chain transactions.

Bridges also reduce barriers to entry for interacting with multiple blockchain networks and contribute to the maturity of blockchain ecosystem. As the demand for crypto bridges continued growing, developers came up with different types of bridges. Some of the notable types of crypto bridges include centralized and decentralized bridges. Most recently, multichain bridges have been garnering all the praise for connecting multiple blockchain networks at once. 

Definition of Multichain Bridges

The term ‘multichain bridges’ might sound a bit confusing as all bridges are supposed to connect multiple blockchain networks. Apparently, the answers to “What is multichain bridge?” leave out the existence of single-chain bridges that work between two specific networks. Multichain bridges are just like any regular software protocol that features smart contracts to facilitate asset transfer or communication between multiple chains. You can also think of multichain bridges as a web of interconnected blockchain networks that offers the best of every protocol.

How Does a Multichain Bridge Work?

Multichain bridges manage the conversion of native assets on one blockchain to wrapped or pegged tokens on the destination blockchain. At the same time, the bridges also ensure secure asset transfer between networks making them almost similar to international bank transfer systems. The common method followed by almost all entries in a multichain bridges list is the ‘lock and mint’ approach. The ‘lock and mint’ method involves locking the native assets on the source blockchain and minting the equivalent amount of wrapped tokens on the destination blockchain.

Do you want to know what happens if you want to release the locked tokens on the source blockchain? You can release the locked tokens by reversing the process or burning equivalent amount of wrapped tokens on the destination blockchain. 

Let us assume a scenario where you want to send ETH tokens to the Polygon blockchain with a multichain bridge. The bridge with lock the amount of ETH tokens you want to send on the source blockchain i.e. Ethereum. In the next step, the bridge will mint the equivalent amount of tokens on Polygon blockchain. When you want your ETH tokens back on the Ethereum blockchain, the wrapped ETH tokens on Polygon will be burned to unlock the original ETH tokens. 

Significance of Multichain Bridges in the Crypto Space

The value of multichain bridges is not limited to cryptocurrencies only as they aim to have an impact on the broader blockchain landscape. Imagine the possibilities that would emerge from services that allow users to explore DeFi apps, NFTs, metaverse platforms, and other solutions without any barriers. The impact of multichain bridges on Ethereum or any other popular blockchain might not be explicitly evident as of now. However, multichain bridges have proved effective for new users who have been seeking opportunities to explore multiple blockchain networks.

You don’t have to exit the blockchain network that you want to capitalize on the offerings of DeFi applications on multiple networks. The solution to the interoperability challenge with multichain bridges also opens new doors for improving liquidity in newer or smaller blockchain ecosystems. In addition, multichain bridges also offer a trusted solution for seamless movement of NFTs between blockchain networks. As a result, bridges improve utility of NFTs alongside opening new marketplaces for them. Another advantage of multichain bridges is the assurance of solution to scalability problems as they can reduce congestion on popular chains.

Do Multichain Bridges Have Any Risks?

The use cases of multichain bridges show that they are the next big thing for the future of blockchain and crypto. The rising number of multichain bridges in crypto indicates that the interoperability challenge has remained unaddressed for a long time. At the same time, something’s good does not mean that it won’t have any bad qualities. Multichain bridges also present certain risks, such as security concerns in the form of smart contract vulnerabilities or centralization issues.

Multichain bridges are likely to present liquidity risks as they can face liquidity crunches during fluctuations in the crypto market. On top of it, bridges also become the most obvious target for attackers as they work as conduits for transferring large amounts of crypto assets.

Navigating Regulatory Risks for Multichain Bridges

The regulatory uncertainty that creates problems for cryptocurrencies also affects multichain bridges. If you use multichain bridges for Ethereum tokens in the United States, then you must comply with certain regulations. One of the key regulatory concerns for multichain bridges is the possibility of classifying them as money transmitters. On the other hand, FinCEN guidelines suggest that multichain bridges don’t hold direct custody of user funds, which excludes them from the definition of money transmitters.

Even if multichain bridges work within the ambit of law, the regulatory landscape can come up with new surprises. Take the worst case scenario as an example in which multichain bridges are classified as money transmitters. It would lead to a huge burden of compliance obligations on bridges, such as registering with the authorities, implementing KYC and AML programs and obtaining money transmitter licenses. 

The cross-border transactions with multichain bridges also create concerns about the applicable laws and jurisdiction. Since multichain bridges, blockchain networks and crypto assets work with decentralization, it is difficult to assign any regulatory responsibility. Multichain bridges will also have to adapt to regulatory frameworks that call for ethical and responsible use of crypto.
