We are in the modern digitalized era. After the creation of the Bitcoin blockchain network, now, we have different consensus algorithm-based blockchain networks so many cryptocurrencies are based on them and this world is continuing to embrace the potential of blockchain and crypto with a wide range of real-world use cases. As the industry is constantly evolving, it's essential to explore new and innovative solutions to address existing challenges/limitations and tap into new opportunities to catch the mainstream adoption trend.

This article attempts to provide some suggestions for innovations in crypto and blockchain that developers could consider. From decentralized finance (DeFi) to AI-enabled blockchain, it highlights some of the most promising areas for growth and development.

Please note that the use cases of blockchain technology are not just limited to crypto but the entire article explores different aspects related to blockchain technology that are correlated with crypto specifically, hope you understand.

Limitations of the Existing Blockchain Networks:

There is no doubt, blockchain technology has attempted to solve various persisting problems (such as centralizations, costs and speed, lack of trust, and security), but it was not free from limitations. Here are some of the most notable limitations.

Some of the latest solutions to overcome the above limitations

Based on the consensus algorithms, use cases, cost and speed, and trust, there are different generations of blockchain technologies. There is already a published Hackernoon story where I explain this. These technologies have attempted to solve persisting limitations to some extent (but they have not completely replaced the blockchain networks with the persisting limitations) which are as follows:

  1. PoS consensus algorithm-based blockchain networks

To combat the issues of disputable energy consumption, low scalability, high fees, and slow transactions, PoS-based blockchain networks have evolved, like Polkadot, Avalanche, and Cardano. Now, Ethereum (initiator of the smart contract features) itself switched to PoS from PoW. Comparatively, PoS-based blockchain networks are more energy efficient than PoW-based blockchain networks as it doesn’t need expensive hardware setups like for Bitcoin mining. Amounts of staked coins/tokens determine the validation power of the validators so we can expect the security of the blockchain. In addition, everyone with staked coins/tokens can participate in different network-related activities like transaction validations, voting for protocol changes, and many more. There are different types of the PoS consensus algorithm which are as follows:

Limitations of the PoS Blockchain Networks:

Despite offering the best solutions to combat the several limitations of the PoW blockchain networks, PoS blockchains are not free from their limitations, which are as follows:

  1. Layer 2 solutions

This refers to the off-chain protocols or mechanisms to process transactions faster and more efficiently like the Bitcoin lightning network does. These solutions are applicable to addressing the scalability issues of the blockchain network. These sorts of solutions work by processing transactions off the main blockchain and then settling them on the blockchain at a later time and the process can be carried out by using payment channels, sidechains, or other mechanisms to enable fast and low-cost transactions. Some examples are Bitcoin Lightning Network and Plasma for Ethereum.

Limitations of the Layer 2 Solutions

  1. Interoperability protocols

They refer to technologies and standards that enable different blockchain networks to communicate and exchange information with each other as Polkadot does to some extent. Interoperability allows for the creation of a more seamless and interconnected ecosystem between different blockchain networks that can support a wider range of use cases and applications with different cryptocurrencies.

Some of the main interoperability protocols in the blockchain include:

Limitations of Interoperability Protocols

Interoperability protocols have almost similar limitations as layer 2 solutions have which as follows:

  1. Invention of a Unique Proof of History (PoH) Consensus Algorithm

To address the scalability and high transaction costs of existing blockchain networks, Solana was the first blockchain network to introduce a unique PoH consensus algorithm with a superfast transaction speed of up to 65,000 TPS. Later other Arweave, Filecoin, and Hashgraph were introduced to be based on the PoH consensus algorithm. The benefits of PoH blockchains (Solana) are:

Limitations of PoH-based Blockchain Network Solana

Here is no doubt, PoH is a unique concept to address most of the shortcomings of other existing blockchain networks but, it is not free from limitations. To assess the long-term viability of the Solana network, it's really important to consider two significant vulnerabilities. One is related to the monolithic design of the network which could potentially lead to centralization. The other vulnerability is related to the overall security of the Solana blockchain network and the potential for security issues to arise due to its own design. It's crucial to understand these vulnerabilities and monitor their impact on the network's stability over time.

Overall, almost all blockchain networks exhibit remarkable shortcomings and developers are continuously thriving to invent new solutions. Technically, there are so many difficulties to going blockchain for the mainstream adoption trend.

To address the potential shortcomings, here are some sets of ideas and suggestions for the developers or experts in the related field to invent the new technologies:

  1. Green Energy

In light of the increasing awareness of the need to reduce carbon emissions, there have been ongoing discussions about alternative solutions for PoW-based transaction mining. As it is closely related to hardware resources like mining machines, computers, smartphones, etc.

✅Innovation Suggestions:

The following suggestions could inspire developers/engineers to come up with new techniques:

👉🏿Invent blockchain networks that are energy-efficient such as PoS-based blockchain consumes comparatively less energy than that PoW-based blockchains.

👉🏿Experts and engineers would invent small but powerful portable devices like smartphones that can handle all blockchain-based applications like transactions mining, validations, trading and storing different cryptocurrencies without excessive energy consumption.

👉🏿Due to technical difficulties, currently, completely abandoning PoW-based blockchain like Bitcoin to switch to another protocol is a very tough task, so developers can focus on designing energy-efficient techniques like workload partitioning, efficient hashing functions, or incorporating hardware-specific optimizations to improve energy efficiency. In addition, miners can be encouraged to use renewable energy(such as solar, wind, or hydroelectric power) for their mining operations. Rewards can be provided to miners who demonstrate their commitment to using clean energy sources.

👉🏿Developers can explore the concept of decentralized energy grids to utilize in blockchain technology.

  1. Decentralized Finance (DeFi)

DeFi is one of the most popular and rapidly growing sectors in the blockchain industry. Developers could create decentralized lending and borrowing platforms, advanced decentralized exchanges (DEXs), stablecoins, and other financial products like dApps and services using advanced blockchain technology.

✅Innovation Suggestion:

👉🏿To address the above limitation, an invention could be a standard mechanism of the widely accepted decentralized regulatory body (Prefer to check the “Governance” section below) for DeFi which could establish and enforce standards and best practices for DeFi platforms.

✅Innovation Suggestions:

These risks can be mitigated by implementing the following features;

👉🏿Stronger security measures such as multi-factor authentication, strong encryption layers, and regular security audits.

👉🏿A standard decentralized insurance platform for DeFi would provide users with protection against losses due to hacks and other security breaches.

👉🏿Unique identity verification mechanisms (such as Decentralized Identity Solutions (DID), biometric authentication, reputation systems to establish trustworthiness within the DeFi ecosystem, and on-chain identity verification mechanisms) to recognize the specific users accessing his/her DeFi platforms.

✅Innovation Suggestions:

👉🏿An innovation could be advanced blockchain technology to support the features of high throughput, low latency, and lower blockchain overhead which is desirable for an advanced DeFi platform. For existing blockchain-based DeFi platforms, advanced layer 2 solutions could be an option to handle the massive influx of DeFi-related activities(Prefer the “Scalability” section below for more details).

✅Innovation Suggestions:

👉🏿An innovation could be a decentralized interoperability protocol for DeFi (including

cross-chain Bridges, inter-protocol communication frameworks that enable DeFi platforms to communicate and interact with each other through standardized protocols, and collaborative partnerships between different DeFi platforms to enhance interoperability) which would enable different DeFi platforms to interact with each other seamlessly.

✅Innovation Suggestions:

👉🏿An innovation could be a user-friendly interface for DeFi by using a simple but powerful programming language which is easier to understand) which would make it easier for non-technical users to access and use DeFi platforms.

This could include the following features:

  • Collaborate with popular wallet providers to integrate DeFi functionalities directly into their UI for easily accessing the DeFi-based features.
  • Develop mobile-friendly applications for accessing and using DeFi platforms.

3. Non-Fungible Tokens (NFTs)

NFTs are digital assets based on the blockchain that represent ownership of unique items (such as art, music, and collectibles). Developers could create new NFT platforms, integrate NFTs into existing applications, or build new use cases for NFTs.

✅Innovation Suggestions:

👉🏿An innovation could be the development of widely accepted NFT standards which could include guidelines for creating and verifying NFTs as well as protocols for interoperability between different NFT platforms by ;

  • Forming an industry consortium or working group consisting of key stakeholders, blockchain developers, NFT platform operators, artists, collectors, and industry experts to define and develop widely accepted NFT standards.
  • Creating standardized metadata specifications that define the required and optional attributes for NFT metadata (such as title, description, image, creator information, provenance, and licensing details).
  • Developing protocols and mechanisms for verifying the authenticity and uniqueness of NFTs by involving cryptographic techniques to prove undisputable ownership and integrity of the underlying digital assets as well as methods for validating each NFT within a given standard.

  1. Interoperability

Interoperability refers to the ability of different blockchain networks to communicate and interact with each other. Developers could create bridges between different blockchain networks to cross-chain transactions and interoperability.

✅Innovation Suggestions:

👉🏿An invention could be the development of common standards or mechanisms that enable different blockchains to communicate with each other and share data by including the development of common,

  • Data formats,
  • Communication protocols, and
  • Application Programming Interfaces (APIs).

✅Innovation Suggestions:

👉🏿An innovation could be the development of a bridge between different blockchains. This middleware could handle the technical complexity of blockchain interoperability to enable different blockchains to communicate with each other seamlessly or create an advanced blockchain network with built-in interoperability feature support.

👉🏿Design smart contract compatibility mechanisms that allow smart contracts to be executed across multiple blockchains by developing a common scripting language or creating translation layers that convert smart contracts from one blockchain's programming language to another.

  1. Privacy and Security

Privacy and security are the most important concerns for blockchain and cryptocurrency users. For example, identity management is still a challenging part of the crypto sphere and interoperability between different blockchains can also raise security and privacy concerns like when it comes to sharing sensitive data between different blockchain systems.

Developers could create new privacy and security solutions like the strongest encryption mechanism, zero-knowledge proofs, multi-signature wallets, and other security features.

✅Innovation Suggestions:

👉🏿To address this, one invention could be the development of a blockchain network that allows obfuscated transactions to achieve anonymity and fungibility while performing the transactions. In the case of the private blockchain network, strong encryption and other security measures (such as the secure connection between the nodes, secure key management, and access control and permissions) should be fulfilled to achieve greater privacy and control over data.

👉🏿Explore the integration of advanced privacy-enhancing cryptographic techniques like ring signatures into the blockchain network.

✅Innovation Suggestions:

👉🏿An invention could be the development of better auditing tools and techniques to identify vulnerabilities in smart contracts and prevent them from being exploited. In addition, developers could seek the possibilities to invent or implement advanced alternatives of smart contracts like;

  • Ricardian Contracts combine natural language text with machine-readable code digitally.
  • Hybrid Solutions could be a combination of smart contracts and other newly invented contracts.
  • Oracles solutions can assist smart contracts to be more flexible and adaptable to changing circumstances.
  • Event-Driven Architecture that works based on real-time events.

✅Innovation Suggestions:

👉🏿An invention could be the development of consensus mechanisms that are more resistant to 51% attacks such as automated Multi-Algorithm Consensus and other new types of advanced consensus algorithms.

👉🏿Encourage the adoption of different consensus algorithms within the blockchain ecosystem to reduce the risk of a successful 51% attack.

👉🏿Continuously work towards increasing the overall hashrate of the blockchain network and implement network monitoring and alert systems that can detect and notify participants about any unusual or suspicious activity by enabling a rapid response to potential 51% attack attempts.

✅Innovation Suggestions:

👉🏿The development of secure storage solutions that protect data stored on the blockchain from unauthorized access could be the best way. In addition, it is not too late to think about the invention of extended decentralized storage capabilities by maintaining scalability at the same time for the blockchains.

👉🏿The development of secure and private data-sharing protocols to enable different blockchains to share data with each other without compromising security or privacy to attackers to take the wrong benefits.

✅Innovation Suggestions:

Some innovations and suggestions which could be highly desirable for the existing and new blockchain networks are as follows:

👉🏿The development of secure and privacy-preserving identity management solutions (such as zero-knowledge proofs that enable users to prove their identity without revealing their real identity to everyone.

👉🏿Explore the concept of self-sovereign identity(SSI) where users have full control over their own identity information.

👉🏿Innovate or improve key management systems to safeguard private keys and ensure secure authentication and authorization that combine strong encryption techniques, hardware security modules, and secure key storage mechanisms to protect users' private keys from unauthorized access.

👉🏿Develop advanced algorithms for identity verification that combines machine learning and artificial intelligence techniques to analyze a wide range of data points to validate identities more accurately by protecting user privacy.

  1. Scalability

As mentioned earlier, scalability is a notable challenge for blockchain networks. Existing blockchains still struggling to meet the growing demands of users to handle so many blockchain-related activities like transaction mining or validations, metaverse platforms-related activities, blockchain gaming activities, DeFi platforms-based transactions, and many more.

✅Innovation Suggestions:

👉🏿Developers could create new scaling solutions (such as sharding, layer-2 protocols, and other techniques) to increase the capacity and speed of blockchain networks to address the notorious issue of most of the blockchain networks i.e. limited transaction throughput. As the size of a blockchain grows over time, so do the difficulties for individual nodes to store the entire blockchain which can lead to centralization as only a few nodes have the subtle hardware resources to store the entire blockchain. To address this issue, two mechanisms could be the best i.e. Pruning to remove old or unnecessary data from the blockchain, reducing its overall storage requirements, and Compression to reduce the size of data stored on the blockchain to make it easier for nodes to store the entire blockchain. If we are thinking about long-term scalability solutions then it would depend on the evolution of the hardware devices like advanced computers, powerful smartphones, internet connectivity speeds, etc.

  1. Governance

In the decentralized blockchain ecosystem, we need a unique governance model and mechanism for the decision-making process. The persisting challenge is, centralization as a small group could take control over different blockchain-related activities by owning the larger percentages of stakes or resources to run the blockchain network. In addition, governance and regulatory challenges could be problematic as different blockchains may be subject to different regulations and governance structures.

✅Innovation Suggestions:

👉🏿New governance models such as decentralized autonomous organizations (DAOs) enable community-driven decision-making and voting process to make changes in the blockchain networks. For example, a blockchain-based social media platform could implement a DAO model where users have voting rights to determine platform policies, content moderation guidelines, and even the distribution of platform revenue among participants.

👉🏿The development of governance frameworks and regulatory standards that enable different blockchains to work together while still complying with relevant regulations and governance structures.

👉🏿Governance models that involve regulatory standards in blockchain networks. This could involve the implementation of identity verification mechanisms, KYC procedures, and anti-money laundering (AML) measures within the blockchain's governance framework. Such solutions would enable blockchain networks to comply with regulatory requirements while still maintaining the benefits of decentralization.

  1. AI-enabled Blockchain

Last but it could be a game-changing suggestion if it is implemented into blockchain technology. There is an already published Hackernoon story too.

Well, we know there are still human interventions in the existing blockchain networks like transaction mining and validations, changes in protocols, producing the new blocks, and adding transactions into the new blocks which could potentially lead to several human-created errors or unfair transaction mining or validation standards or mechanisms modifications. AI-enabled blockchain is a new evolving field that combines blockchain technology with artificial intelligence (AI) with the goal to create a more intelligent and automated blockchain system where AI algorithms could be used to optimize and improve various aspects of the blockchain network.

Here are some potential use cases for AI-enabled blockchain:

These are just a few of the many areas where developers and concerned experts could innovate in the crypto and blockchain industry. With the rapid pace of technological development and adoption, there are always new opportunities for creative and innovative solutions in this field.

Conclusion:

The fact is, there are certain limitations to the current state of crypto and blockchain technology but there are also many exciting opportunities for innovation and growth of this evolving industry. New technology development progress for quantum computing and quantum encryptions is ongoing so it would not be a bad idea to think about advanced solutions to get tuned with the pace of technologies. In addition, there are also many opportunities for innovation and growth in the crypto and blockchain space such as the integration of AI, the development of decentralized finance (DeFi) applications, and the expansion of NFTs beyond the world of digital art. Ultimately, the continued growth and success of crypto and blockchain technology will depend on the ability of developers, entrepreneurs, and other stakeholders to identify and address the limitations of the technology while also pursuing innovative new applications and use cases. With the right combination of vision, creativity, and technical expertise, the potential of crypto and blockchain is truly limitless.
