Layer 1 solutions

While first-generation blockchains have established the decentralized financial infrastructure of the future, they can’t scale very well. At times, layer-1 blockchains are slow due to network congestion, but layer-2 solutions alleviate this problem by moving computations from the main blockchain to a separate system that performs these functions. This is known as sharding, and it has many advantages. This type of scaling is very simple and inexpensive.

As the blockchain space continues to expand, this problem becomes even more critical. In order to scale blockchains, researchers are coming up with different solutions to solve it. The Layer-1 solutions target the working principles of blockchains and propose new consensus mechanisms, such as sharding and Directed Acyclic Graphs (DAGs). While these solutions have their advantages, they have their drawbacks. In general, layer-1 solutions don’t offer backward compatibility. If one changes the consensus mechanism, the system will fork.

Most blockchain solutions use trusted third parties for data collection and validation. They also rely on the staff of the supply chain parties to input data. To improve data integrity, most solutions involve the use of product inspections, reputation history, and financial penalties. Only two papers described dispute processes on blockchain solutions. The remaining solutions rely on third-party input, customer feedback, and external oracles to collect data.

Permissioned ledgers

A permissioned ledger is a type of blockchain that has no central entity. All participants in a permissioned blockchain are equally responsible for guarding and controlling the information posted to it. The distributed nature of permissioned networks provides an additional layer of trust to the participants. Furthermore, permissioned ledgers are more secure due to the simultaneous access of members, reducing the chances of data alteration.

A common example of a permissioned blockchain is a supply chain for a widget. Raw1 Company produces the raw material while Raw2 Company and Make3 Company manufacture the widget. The final chain involves the sales and payables of the final product. In this example, the permissioned blockchain will allow each participant to maintain a history of transactions. As the chain progresses, the blockchain will track each batch.

As the name suggests, permissioned blockchains are closed to unauthorized users. Each user has a unique key, which they can use to make changes. In addition, every change is tracked and the administrator is aware of who made them. The permission system adds another layer of security and governability to the blockchain network. The superseding regulator of a permissioned blockchain will manage the permissions of the participants.

As the name implies, permissioned blockchains allow you to customize the network and control what roles are appropriate for your organization. While permissionless blockchains are open to everyone, permissioned ledgers are designed for closed networks where access to data is restricted. For instance, a company’s blockchain may contain sensitive financial information that it wants to protect. For businesses and governments, permissioned blockchains will help them maintain their privacy and control.

Central bank digital currency

The idea for a central bank digital currency was inspired by Bitcoin and other blockchain-based cryptocurrencies. These currencies would allow citizens to hold accounts and provide a reliable and secure public payment and savings medium. One of the main benefits of such currencies is the ability to reduce risk. Currently, merchants accept a certain amount of risk in the form of slow payment verification, but instantaneous payment verification will eliminate this risk entirely. This eliminates the need for intermediaries and risk management for merchants.

CBDCs and crypto are networked electronic resources. Each ‘e-coin’ has a unique serial number issued by the central bank. These new digital forms of money are gaining widespread acceptance and are being tested in many countries. For example, in France, 500 institutions have tested a CBDC issued by the Banque de France. The entities involved in the testing used this digital currency to settle trades. China has been developing a prototype CBDC for over two years, and the People’s Bank of China’s Digital Currency Institute is responsible for its development. Eventually, the CBDC could replace all cash payments, reducing fraud and increasing transparency in financial transactions.

While a central bank digital currency is a great way to simplify the process of transferring money, it is still not a perfect solution for every country. Blockchain technology allows for the distribution of central bank digital currency, which is both faster and cheaper than the traditional financial system. With this digital currency, companies and citizens would be able to transact money instantly, without any fees. The benefits of this digital currency are numerous.

IoT applications

A Look at the Current State of Blockchain for Industrial IoT applications highlights several limitations. Existing blockchain projects rely on powerful computers to maintain the network, but the IoT devices themselves are not capable of such a feat. To avoid such problems, light nodes can be programmed to propose concurrent sets and use their computation power to process data. The most common types of transactions that blockchains can verify are resource exchanges and interactions between devices and services.

A key benefit of blockchain for IoT is its ability to endow devices with the concept of ownership. The use of cryptographic primitives ensures that every device has a unique identity, so the devices can sign for and encrypt assets. This allows them to own digital assets, including Bitcoin. As a result, IoT devices can act in their own economic interest, reducing their overall costs.

IoT devices currently use simple, plaintext passwords to communicate. Often, these passwords are reused by manufacturers, making them easy to hack. Malware like Mirai aims to exploit this vulnerability. Because of the limited computing power of connected devices, they need to relay information to the cloud. And because IoT devices are often physically near each other, the data they contain can be corrupted or stolen.

Security

The Chinese government is looking at blockchain as a way to improve efficiency and defend against foreign adversaries. Though the government has been nonspecific about the exact projects that are based on blockchain, it has been looking into cybersecurity issues in general. The blockchain is also finding use in the Internet of Things, an industry that presents a variety of cybersecurity challenges. To better understand these concerns, let’s look at some of the projects that are using blockchain.

One of the most common uses of blockchain technology is for securing cryptocurrencies. It has already been applied to cybersecurity problems and facilitates transactions between parties. Because the ledger is decentralized, it is nearly impossible to alter and forge records. Blockchains are also a viable option for data storage and identity management. They could help solve a wide range of other cybersecurity challenges. Using blockchain technology in these ways can improve our security and ensure that data is secure.

Another example of blockchain technology is its use in democratic elections. The immutability of the chain makes fraudulent voting extremely difficult. Voters could be issued a token by a voting system. Each candidate would be given a wallet address, and citizens would send the tokens to this address. By using blockchain technology in democratic elections, the U.S. military would be protected from hacker attacks. There are also several regulatory and enforcement issues to keep in mind when implementing blockchain technology.

Scalability

Public blockchains, however, may face a key challenge: scaling. As the number of participants increases, so does the transaction volume. This, in turn, puts more strain on full nodes, which compromises the decentralized properties of blockchains. To improve scalability, methods involving off-chain transactions are being considered. Bitcoin and Ethereum are two examples. However, Bitcoin blockchains are less scalable than Ethereum, since mining requires 10 minutes while Ethereum requires 20 seconds. In addition, blockchains in public networks have costs associated with completing a transaction. The Bitcoin network, for example, has a high per-transaction BTC spending, while Ethereum requires a small gas price.

The scalability of blockchain is an essential requirement for achieving widespread adoption. High transactional volumes, as well as the number of users, miners, and transactions, can degrade a blockchain’s performance. Hence, scalability must be improved in order to meet the needs of a wider range of industries. Until this fundamental issue is solved, blockchain may not be able to compete with centralized systems.

The two most important factors affecting scalability are throughput and latency. Blockchain scalability is also influenced by the speed at which transactions are verified by the network. As such, decentralized systems have several advantages over centralized ones. However, this scalability issue is one of the most pressing problems facing the technology. To overcome the scaling problem, various approaches are being tested. Some of these solutions may require an interdisciplinary effort, combining perspectives from engineering optimisation and regulatory policies.
