Recent Blockchain Developments
In Ethereum, there's an equivalent concept of gas limit gas is a measure of computation which induces an upper-cap on the amount of gas that all transactions in the block can consume.
We can increase the block size so that more transactions can fit into it. There is information related to each transaction that needs to be maintained in each block for security and verifiability. If we can somehow reduce the amount of information required, we can achieve better throughput. Some of the ideas could be". How often a new block is added to the blockchain also impacts the transaction rate.
The time is a function of the block difficulty level in PoW systems. In Bitcoin, the average block-creation time is 10 minutes, and in Ethereum, it's 7 seconds.
Reducing this time would mean more transactions going through at a faster rate. The number of transactions in a block multiplied with the frequency of block addition gives us the upper-limit for the transaction rate. You might wonder, if increasing the transaction rate is as simple as increasing the block size and frequency of block addition, why is there all that fuss about scaling? It's tricky, and let's go over why. This is worse than it appears because the node finding a legit block would get a head start on the next block and so on.
It will tend to favor the large miner groups and hence centralization. Also, both of the changes would require hard forks non-backward compatible upgrade to the chain function.
Depending upon the protocol implementation, there's an exchange of information between the nodes in every transaction confirmation or block added. For example, in Bitcoin, the transaction is propagated twice, first in the transaction broadcasting phase, and then after being mined in a block. Since every over-the-network communication costs some time, utilizing the network bandwidth more efficiently is one area we can focus at for improving the throughput. Increasing the connectivity between the nodes can also reduce the propagation delay to some extent.
The speed of consensus would also affect the throughput of the blockchain system. Proof of Work PoW involves a lot of computation, and the block difficulty only gets higher with scale, which means more time and resources to process a transaction. And not to mention that PoW is unsustainable. One of the famous consensus technique is Proof of Stake PoS.
In PoS, the miners or rather validators will have to put their tokens at stake to validate a transaction. The validators will get the reward usually proportional to their stake, but other variations also exist for validating and processing the transaction, and will lose their stake in case of failure to validate a transaction.
Compared to PoW, PoS is sustainable in terms of electricity consumption. PoS will also result in an improved frequency of block addition since miners don't have to spend time solving the cryptographic puzzles. Also, Ethereum tokens are more evenly distributed than the current hash-rate distribution of the miners, so it provides more finality and decentralization than PoW.
There are still some caveats with PoS, and there are many variations of it being worked upon currently. In Bitcoin, we store all the blocks across all the nodes, which requires a lot of storage space. A miner node needs to have the entire blockchain state to be able to verify new blocks. The size of this storage is only going to increase over time. This will rule small individual miners out of business who can't afford to have too much storage capacity and favor large groups of miners and hence centralization.
The problem becomes worse if we increase the transaction rate since it means data is getting into the chain at a faster rate. So the question is, do we really need to replicate everything? Is it possible to prune the data needed to be maintained by the nodes without compromising with the existing functionality? The off-chaining concept, as the name suggests, involves getting some of the processing done off the main-chain. This would decrease the load on the blockchain network and the transaction processing cost.
In off-chaining, not every, but only a few nodes are allowed to compute the complex proof. The participant nodes have to submit a deposit before computing the proof. When the proof is obtained, it is verified by a group of nodes. If the proof is correct, the submitter gets the deposit back along with the reward. Otherwise, the deposit is fortified. The idea of state channels is to establish a communication channel between participants so that state updates and transaction processing can be offloaded to them.
A smart contract an implementation of Hashed Timelock contracts locks a part of the blockchain state enforcing the business logic among the participants. The participants perform multi-signed transactions amongst each other without the involvement of blockchain.
Finally, the resultant state can be submitted directly to the blockchain without the involvement of miners which reduces the time taken. The smart contract makes sure that the transactions are legitimate, updates the state, and the locked portion of blockchain state is now unlocked.
The idea here is similar to how sharding happens in typical databases. The blockchain state is divided into different shards, and a node doesn't need to depend on the entire data to verify and process a transaction. The transactions will be directed to the nodes based on the shards they affect, and all the nodes work in parallel, thereby reducing the overall time taken.
How shards communicate with each other and arrive on consensus is an active area of research. Also, sharding is more secure if applied in a PoS based system instead of PoW.
The validators for a shard are chosen randomly. The holy grail of PoW security is the amount of computations required to outperform the majority, which would be reduced in the case of sharding, making it easier to attack shards with a lower hash rate.
Sharding in Ethereum has been discussed in detail in this post. Subchain architecture has a tree-like hierarchical structure, having a root chain and a bunch of child chains.
It works on the concept of strong blocks and weak blocks. Weak blocks are the blocks that meet a weaker difficulty target. The weak block is broadcasted to other miners as soon as it is found. Miners pile up weak blocks until a block with the defined difficulty target is found strong block.
Once the target is met, the child chain is closed and linked to the root chain, reducing the average first confirmation time of transactions. Subchains were proposed as a layered solution above the existing Bitcoin architecture, and more details can be found in this paper.
Making the change is not as easy as it sounds. In a decentralized system, we cannot force anyone to do anything. For a change to be implemented, the consent of all the stakeholders miners, developers, and users needs to be established, otherwise, community splits happen —like what happened in the case of Bitcoin Cash and Ethereum Classic.
Not to mention, there are big corporations, politicians, and governments who make the process tougher through regulations especially if the change conflicts with their interests. Even if everyone favors the change, it's not an easy process for the developers, since all upgrades have to be backward-compatible as there's no such thing called forced-updates in a system that's decentralized. Any sort of failing in these systems is absolutely unacceptable, and hence rigorous testing needs to be performed before going live with any changes a corrupted blockchain is of no use.
Community splits due to an opinionated change are very costly to the entire blockchain ecosystem, as maintaining a blockchain system requires a lot of effort, and hence requires a passionate community. The Bitcoin community has been actively working on improving the system. Every proposed change for improvement is documented in a Bitcoin Improvement Proposal and only implemented after the consensus of Bitcoin users.
Bitcoin is an open source project, but funding can also play a role in prioritizing the changes to implement. Here are some of the notable changes in the context of scalability, which we'll go into more detail on:.

The blockchain technology first made its official appearance almost a decade ago, in the year Since then, the world has seen an exponential transformation in this remarkable technology.
From the retail sector to the field of Healthcare and Medicine, blockchain technology has made its way into various industry verticals, thus making blockchain trends the most searched keyword. Clearly, the future has a lot of scope for blockchain-based applications. The advent of brought a lot of excitement in the latest blockchain technology. It is sure to take mobile app transactions and business functioning to newer and unimaginable heights.
Here are the top emerging trends in blockchain technology. The term Federated Blockchain can be referred to as one of the best blockchain latest trends in the industry. It is merely an upgraded form of the basic blockchain model , which makes it more ideal for many specific use cases.
As per experts, there will be a rise in the usage of federated blockchain as it provides private blockchain, a more customizable outlook. For most of the part, federated blockchains are quite similar to private blockchains, with a few added features. For instance, in this type of blockchain, instead of one organization, multiple authorities can control the pre-selected nodes of blockchain. Now, this selected group of various nodes will validate the block so that the transactions can be processed further.
Cryptocurrencies are basically a side product of blockchain technology and are volatile in nature. As of now, stable coins are in their initial phase and it is predicted that will be the year when blockchain stable coins will achieve their all-time high, thus making them the second most looked forward emerging tech trends in the industry. It is a new blockchain trend that is currently integrated with a number of startups as well as enterprises.
But such blockchain future trends may not always be feasible when it comes to creating, maintaining, and managing a new blockchain solution. BaaS is a cloud-based service that enables users to develop their own digital products by working with blockchain. These digital products may be smart contracts, applications, or even other services that can work without any setup requirements of the complete blockchain-based infrastructure.
Some of the companies developing a blockchain that provide BaaS service are Microsoft and Amazon, thus shaping the future of blockchain applications. In fact, according to Statista , it is estimated that in , there will be around 2. The introduction of blockchain in social media will be able to solve the problems related to notorious scandals, privacy violations, data control, and content relevance. Thus, the blockchain blend in the social media domain is another emerging technology trend.
With the implementation of blockchain, it can be ensured that all the social media published data remain untraceable and cannot be duplicated, even after its deletion. Moreover, users will get to store data more securely and maintain their ownership. Blockchain also ensures that the power of content relevance lies in the hands of those who created it, instead of the platform owners.
This makes the user feel more secure as they can control what they want to see.
