Avalanche rose $230M in 2021. Solana gained 9160% that year. Ethereum, the premier smart contract platform, is driving Layer-1 (L1) blockchains and associated ecosystems this year. JPMorgan forecasts that Ethereum (ETH) will lose its lead in decentralized finance (DeFi) unless its predicted hard split and switch to Proof-of-Stake consensus happen soon. 2022 is the year of protocol tokens, making it the ideal moment to develop blockchain protocols. Protocol tokens, like BTC and ETH, are blockchain-specific. They may be “wrapped” on any blockchain and on their own. WBTC, a wrapped ERC20 token, may be utilized on Ethereum. Trading is about the token’s core, not its blockchain. Blockchain Protocols Ideal token differ from DAO tokens, NFT tokens, stablecoins, and others.
5 essential Blockchain Protocols Ideal
Consensus mechanism- NPoS. This protocol was inspired by the sequential Phragmen approach, which optimizes elections with several contenders and winners. This is done to increase variety of representation, such as in a parliament, and to prevent having only members of the single major party present. The same algorithm serves as the foundation for NPoS, which ensures decentralization and equitable representation.
How validators are elected using all nominator votes? Polkadot provides elected validators equal voice in the consensus mechanism, unlike other PoS-based initiatives that weight validators by stake.
Average block time: 6 sec.
Weight-based transactions cost $0.10–0.20. Polkadot transactions use transaction weight instead of gas. The weight-based model is similar to the gas model, but in Polkadot, you know the transaction fee upfront, while in Ethereum, you only know the required gas at the end of the transaction.
Polkadot is a “chain of chains” or “Layer 0” meta-protocol. It supports 100–250 parachains that compete to process its primary chain. Polkadot’s XCMP protocol’s complexity and cost limit the number of parachains. Given that each parachain has its own performance and attributes, any estimate of a parachain cap is theoretical. Polkadot strives for a 10:1 validator-to-parachain ratio to encourage decentralization and performance.
Parachains are parallel Polkadot Network blockchains that can link to the main relay chain if they win a parachain slot auction. Polkadot has several appeals. For example, Polkadot will be more predictable in transaction speed and charge in a few years when it is fully coupled with parachains.
Polkadot also resists 51% attacks. Polkadot offers shared security by requiring an attacker to hijack 51% of every parachain connected to its relay chain, making the effort significantly tougher.
Consensus mechanism: Snowball. Avalanche gives a great example: Imagine a room full of people attempting to decide what to eat during lunch. Pizza vs. barbeque. Pizza or barbecue? Everyone wants unanimity.
Everyone asks a random group what they want for lunch. The individual thinks, “Ok, looks like pizza is winning.” Pizza’s better.” They follow the majority. If most say BBQ, the person chooses barbecue.
All repeat this. More individuals agree each round. The more individuals who like a choice, the more likely someone is to obtain a majority reply and choose it. After several rounds, they choose one idea that everyone likes.
Average block time: 2 sec.
Average transaction fee: <$1.0
Avalanche protocols use repeated sub-sampled voting. A validator requests a small random group of validators to approve or reject a transaction.
Ava Labs created open-source Avalanche. Anyone may implement DeFi apps and blockchains in a scalable ecosystem. Avalanche is a “platform of platforms” with hundreds of interconnected subnets.
The Avalanche Foundation introduced Avalanche Multiverse, a $290M (up to 4M AVAX) incentive program to accelerate the acceptance and expansion of its “subnet” capability, which allows a rich ecosystem of scalable app-specific blockchains. The initiative supports blockchain-enabled gaming, DeFi, NFTs, and institutional use cases initially.
Avax supports Solidity smart-contracts and includes a guide for installing a common Ethereum smart-contract on Avalanche.
Avalanche protocols are quick. The creators say it can process over 4,500 transactions per second, like Visa.
Avalanche allows an infinite number of compatible blockchains for 1 AVAX per connection, unlike Polkadot, which has a limit on parachain auctions. Avalanche’s low transaction cost makes DeFi marketplace transactions easier.
Consensus method: Proof-of-History (PoH) is a time validation mechanism with a single source of truth in the network that generates values that cannot be anticipated but can be validated after a set period. If you receive an email containing a link to a news piece, you know it was sent after the article was published. Exchange data might be a core truth source. Participants don’t have to negotiate every second as in other blockchains. Verifying transactions without timestamps speeds up blockchain.

Solana has surpassed Polkadot and Avalanche in market valuation, reaching $30 billion. Solana’s additional strengths?
GPUs can maintain 50,000 tps on the 200-node Solana testnet.

The PoH protocol scales the blockchain network with Moore’s law by increasing device power.
Consensus mechanism: Proof-of-Stake (PoS)
Polygon addresses Ethereum’s inefficiency and scalability, which have lagged behind its growth. Polygon, a Layer-2 scaling solution for Ethereum, is one of the most popular blockchain application solutions across all blockchains due to its quicker, cheaper, and more scalable network. Polygon is very compatible with Ethereum, therefore Ethereum developers and users may easily move to Polygon.
Average transaction fee: $0.002.
Polygon is Ethereum-compatible; hence many Ethereum-based applications have integrated its blockchain. Polygon’s extensive scalability possibilities and inexpensive transaction fees have attracted some of the top Web3 platforms and developers.
Polygon introduced Aave and Curve last year. Scaling metaverses like Decentraland use it. UniSwap and SushiSwap, decentralized crypto exchanges, allow users to swap tokens without middlemen on Polygon.
Many Polygon-only projects exist. Alchemy reports that 55% of projects are Polygon-only and 45% support Ethereum.
Tether is the largest stablecoin (approximately $73 billion), debuted its coins (“USD”) on Polygon on May 27. Polygon is a worthy rival to Layer 1 protocols and a potential network implementation option.
Consensus mechanism: Proof of Staked Authority (PoSA) combines DPoS with PoA. Traditional Proof-of-Stake consensus involves network members validating blocks with their own cash. Delegates are selected from all stakeholders (21 for BSC).
PoA then covers delegate selection. Unlike Polkadot’s NPoS, PoA selects delegates centrally. Binance selects KYC-compliant BSC delegates. This increases network centralization but improves interoperability with government institutions and transaction processing speed (centralized processing does not require network consensus).
Average block time: 3 sec.

Binance, a major crypto player, uses BSC. Binance builds its centralized crypto-exchange (CEX) and cryptocurrency wallet on BSC. A blockchain that solves complicated challenges needs significant attention. This blockchain ranks 5th on CoinMarketCap (May 2022) with a $50 billion market value
After discovering that Binance Chain lacked smart-contracts, Binance Smart Chain was created. Developers may switch from Ethereum to BSC to gain from blockchain speed with the new EVM-compatible BSC.
Binance Smart Chain provides cheap transaction costs. Due to BSC’s huge network capacity, gas prices remain largely steady, preventing transaction queue overflow.
