blockchain

TL;DR: A Layer 1 blockchain is the base network that runs its own consensus and settles its own transactions — think $BTC , $ETH , $BNB , SOL, and AVAX. There is no single "best" #Layer1 for everyone; the right pick depends on what you value most: security and decentralization, transaction speed and cost, or developer ecosystem size. This guide breaks down how to actually compare them and how to get an account set up if you want to hold or trade any of these assets.
◆ What Is a Layer 1 Blockchain, Exactly
A Layer 1 is a blockchain that processes and finalizes transactions on its own base layer, without depending on another chain underneath it. Bitcoin, Ethereum, BNB Chain, Solana, and Avalanche are all Layer 1s. Layer 2 networks, by contrast, are built on top of a Layer 1 (often Ethereum) to add speed or reduce fees while still relying on the base chain for final settlement and security.
The distinction matters because a Layer 1's core design choices — its consensus mechanism, validator structure, and block architecture — set a hard ceiling on what everything built on top of it can do. You cannot bolt better decentralization onto a chain after launch; it is baked into the base protocol from day one.
◆ The Four Things That Actually Separate Layer 1s
Most comparisons get distracted by transactions-per-second marketing numbers. Four structural factors matter more for a long-term hold or a project you plan to build on:
· Consensus mechanism — Proof of Work ($BTC ) prioritizes security and censorship resistance at the cost of speed. Proof of Stake ($ETH , $BNB , SOL, AVAX) trades some of that for throughput and lower energy use, but validator concentration becomes the thing to watch.
· Decentralization of validators/miners — a chain with a small number of entities controlling most validation power is more efficient but more exposed to coordinated censorship or downtime. Chains with thousands of independent, geographically spread validators are harder to compromise but often slower to upgrade.
· Real economic security — this is the total value that would need to be attacked (staked capital or mining hash power) to compromise the network. Older, larger networks generally carry more of this by virtue of age and adoption, not marketing.
· Developer and liquidity ecosystem — a Layer 1 is only as useful as what is built on it. Look at how many independent applications, stablecoins, and bridges are actively used, not just how many exist.
◆ Bitcoin, Ethereum, BNB Chain, Solana, and Avalanche: Where Each One Leans
$BTC leans hardest into security and predictability. It intentionally sacrifices speed and programmability to remain the most conservative, most decentralized settlement layer in the space. It is the benchmark other Layer 1s get measured against, not because it does the most, but because it does the least and does it reliably.
$ETH prioritizes being a global settlement and smart contract layer with the deepest developer ecosystem. Its Proof-of-Stake design and large validator set aim to balance decentralization with the throughput needed to support a wide range of applications, from stablecoins to tokenized assets.
$BNB Chain is built for speed and low transaction costs, with tight integration into a large exchange ecosystem. That makes it attractive for frequent, smaller transactions and for users who want quick access to a wide range of listed tokens without high gas costs eating into small trades.
SOL is optimized for raw transaction throughput using a unique timestamping approach alongside Proof of Stake. It tends to appeal to applications that need very fast, very cheap execution, such as high-frequency trading interfaces or consumer apps.
AVAX uses a distinct consensus protocol and a subnet architecture that lets projects launch semi-independent chains under the Avalanche umbrella. This appeals to teams that want Layer 1-level customization without building consensus from scratch.
None of this changes daily — these are structural, architectural differences, not price levels or rankings that shift with market sentiment. That is the right lens for a "best Layer 1" decision, rather than chasing whichever chain had the loudest headline last week.
◆ How to Actually Get Started Holding or Trading These Assets
Comparing Layer 1s is only useful if you can act on it. To buy, hold, or trade $BTC , $ETH , $BNB , SOL, or AVAX, you need an account on an exchange that lists all of them side by side.
Registration steps are straightforward: sign up with an email or phone number, complete identity verification (KYC), and enable two-factor authentication before you deposit anything. New account registration currently comes with sign-up bonuses/welfare rewards through the link below — check the current offer details on the registration page, since bonus programs are updated from time to time.

If you are on iPhone, note that the App Store listing depends on your Apple ID's region. The mainland China App Store has delisted the Binance app, so you will not find it there at all. The United States App Store only offers Binance.US, which is a separate, independently operated platform — it does not share accounts with the global Binance platform, so a global registration will not let you log into that app. If you want the global app on iOS, use an Apple ID region other than mainland China or the United States; Taiwan or Hong Kong region accounts work well and do not require a local phone number or bank card to set up.
◆ Common Mistakes People Make When Picking a Layer 1
· Chasing the highest advertised speed without checking validator decentralization — a fast chain with few validators is a different risk profile than a fast chain with many.
· Assuming "biggest ecosystem" always means "best fit" — a large developer ecosystem matters for building, but if you are simply holding or trading, transaction cost and exchange support may matter more.
· Treating Layer 1 choice as permanent — most active users hold assets across several Layer 1s rather than betting on just one, precisely because each optimizes for different tradeoffs.
· Ignoring security settings after registration — the account setup matters as much as the asset choice. Two-factor authentication and a withdrawal address whitelist take a few minutes and meaningfully reduce account risk.
◆ FAQ
Q: What is the difference between a Layer 1 and a Layer 2 blockchain?
A: A Layer 1 handles its own consensus and final settlement independently. A Layer 2 runs on top of a Layer 1, using it for final security and settlement while adding speed or lower fees on top.
Q: Is Bitcoin or Ethereum the "better" Layer 1?
A: They optimize for different goals. Bitcoin prioritizes maximal security and simplicity as a settlement layer; Ethereum prioritizes a broad smart contract and application ecosystem. "Better" depends on what you are using it for.
Q: Do I need to pick just one Layer 1 to invest in?
A: No. Most active crypto users hold and trade across several Layer 1s ($BTC , $ETH , $BNB , SOL, AVAX among others) because each serves different use cases rather than competing to be a single universal winner.
Q: Can I use my global Binance account on the iOS App Store in the US or mainland China?
A: Not directly. The mainland China App Store does not list Binance at all. The US App Store only offers Binance.US, a separate platform with its own account system that does not connect to the global platform. Use an Apple ID region outside mainland China and the US, such as Taiwan or Hong Kong, to access the global app on iOS.
Q: What should I do right after registering an account?
A: Complete identity verification, turn on two-factor authentication using an authenticator app rather than SMS only, and set up a withdrawal address whitelist before depositing significant funds.
