There is a lot of innovation in consensus mechanisms and is a field that is constantly evolving and contributing to the array of distributed ledgers known today.
Some networks provide security and decentralization at layer one and then delegate speed to layer two solutions. Layer 2 networks extend the functionality of their layer 1 counterpart. Similar to how Layer 1 networks have different approaches to consensus, each layer 2 network will implement a scaling solution, or means to map transactions back to its layer 1. For instance, a commonly discussed layer 2 scaling solution is the implementation of zero-knowledge rollups.
The idea is that a side-chain performs transaction ordering and processing and submits mathematical proof that they have processed the transactions fairly. Some examples of layer two scaling solutions are the Lightning Network , Polygon , and Starknet. The majority of scaling layer two solutions depend on cryptographic systems. For resources on the cryptography behind zero-knowledge proofs, I recommend this resource.
The watered-down version of what is happening is that a mathematical proof is created by a verifier that some knowledge is correct. Lighting network - Scaling with 2 party multi-signature channels.

Ethereum stands out as the cryptocurrency with the most institutional dominance. It may also signify that Algorand is succeeding in its goal of enabling a high volume of smaller transactions. Overall, the level of institutional interest in Bitcoin stays stable, but not so for Ethereum and Algorand.
Ethereum saw a slight dip in institutional interest beginning in November , which has yet to recover. Algorand, on the other hand, saw a much larger dip beginning in September, which has only seen a modest recovery. Still, the rise of DeFi appears to have sparked a huge increase in investor sentiment for Ethereum relative to Bitcoin.
That speaks to the power of web3: Smart contract functionality has created new use cases for Ethereum, leading to drastic increases in usage, and investors have taken notice. Due to its PoW consensus mechanism and current methodology for processing transactions, Ethereum can only handle roughly 15 transactions per second, compared to for non-cryptocurrency solutions such as the Visa network.
This is especially true for smaller transactions. Not only that, but gas fees vary greatly hour-to-hour depending on how many people are transacting. The grid below shows average gas fees as a percentage of transaction totals by hour and day of week for the six months prior to the London Hard Fork. For now though, high gas fees, and the negative effects they have on dApp scalability, are the primary reason many developers see opportunities in creating new smart contract-enabled blockchains.
PoH seeks to solve the issue of timestamping transactions that occur on a blockchain, which determines the order in which validators confirm those transactions. That steady growth suggests that participation in the Solana ecosystem is growing consistently regardless of price swings.
One area where Solana is growing rapidly is NFTs. Solana still trails Ethereum in overall NFT trade volume, though it has surpassed it in individual hour periods. It remains to be seen if the ease with which new NFTs can be created on Solana at such low costs will allow it to supplant Ethereum as the blockchain of choice for NFTs, given that the latter has a first mover advantage and more transaction volume.
Currently, Algorand facilitates an estimated 1, transactions per second with five seconds for final confirmation on the blockchain.
It achieves this in part with a unique, two-tiered blockchain structure. The base layer supports basic transactions, as well as smart contracts for new tokens and atomic swaps. The second layer, on the other hand, is reserved for more complex smart contracts, such as those powering dApps.
This bifurcation of the Algorand blockchain enables Algorand to process transactions efficiently. This results in a more democratized blockchain, but the lower barrier to entry may disincentivize validators from acting in the best interest of the entire network at all times. However, with gas fees running high on Ethereum, many developers have chosen to build dApps on Algorand.
We break down the biggest of those dApps by transaction volume below. Most transaction volume for Algorand is moving through big, centralized exchanges, but its staking rewards pool also sees significant activity. BNB chain achieved high growth for a few reasons, a key one being its capability of supporting new tokens and dApps without the high fees of Ethereum.
However, there are potential downsides to that as well. But what exactly is being built? Meanwhile, platforms devoted to NFTs and other collectibles are much less prominent.
Avalanche accomplishes this with a set of three blockchains , each serving different use cases:. Subnets are sets of Avalanche validators responsible for a single blockchain built on top of Avalanche. Each layer 2 blockchain on top of Avalanche has one subnet, but individual subnets can validate many blockchains.
Meanwhile, its PoS consensus mechanism has enabled low fees and a high throughput of 4, transactions per second. Unlike Ethereum, Avalanche burns all transaction fees in order to create deflationary pressure for its native AVAX token, rather than pay them out to validators, as is the case on the Ethereum blockchain.
While many of them have attracted substantial investment and user bases, questions remain. For instance, will any of them surpass Ethereum in adoption?
Ethereum is still far ahead in transaction volume, especially in popular areas of web3 like NFTs, and the Ethereum Foundation is working with miners to implement changes to address its issues. The upcoming Ethereum 2.
An excellent example of this is Bitcoin. While its blockchain has managed to optimize decentralization and security, it has had to compromise on scalability ï¿½ through no fault of its own. Blockchain scalability is the expansion of a network in digital space in terms of transaction processing speeds and processing power to accommodate the addition of new applications and the increase in user operations.
By scaling, blockchain networks can compete with centralized networks for transaction volumes, application buildup, and user engagement if they offer higher processing capacity. One of the fundamental approaches to tackling the scalability problem is introducing layer-1 solutions. A layer-1 blockchain is the base protocol itself, and improving this ground-level infrastructure can make the system much more scalable.
The two most popular layer-1 improvements include modifying the consensus protocol and introducing sharding functionality. However, Bitcoin remains the most affected by scalability issues, since the underlying network relies on the increase in the number of miners to ensure higher transaction throughput and volumes. To achieve this, network architects and developers rely on several methods to increase the system's scalability. Proof-of-work , or PoW, is the original consensus mechanism used in Bitcoin and Ethereum, although the latter has recently migrated to proof-of-stake PoS , described further below.
PoW aims to achieve validator consensus and network security by incentivizing miners to commit computing power to solve complex cryptographic puzzles. However, PoW struggles with two main issues: it can be comparatively slow and resource-intensive. Proof-of-stake , or PoS, is a different mechanism for reaching a distributed consensus in a blockchain network.
Validators authenticate block transactions based on their holdings of the blockchain's native token, or their "stake" in the network. While in PoW-based systems it is the expanded computational power that ensures that validators have sufficient "skin in the game" and are disincentivized to game the system, in PoS it is holding a sizable amount of the blockchain's token whose value can drop if the decentralized consensus is breached.
Switching from one consensus mechanism to another can massively improve a blockchain's throughput and help it scale. Yet, such a dramatic change can be challenging to implement as it requires a broad consensus among the network's participants. Sharding is another approach to improving scalability that has been ported from the distributed databases sector and adapted for layer-1 blockchains. This helps to increase the network's overall capacity.
