This article will show a comparison between blockchains such as $HBAR and $ALGO
The following coins (blockchains) were chosen as they are among the fastest and most reliable in transaction blockchains. Solana lags behind in speed and data volume.
Evaluation criteria
Speed (TPS, Transactions Per Second): how many actual transactions per second the network can process. There are theoretical (maximum) and real indicators.
Reliability:
Time to Finality — how many seconds it takes for a transaction to be considered irreversible.
Uptime/downtime — whether there have been any outages or major failures in the network.
Scalability🍕
Ethereum Layer-1 processes over 1,160,000 transactions per day (≈13 TPS) Electro IQ, but is actively transitioning to Rollup solutions (L2), where dozens of projects already reach hundreds to thousands of TPS.
Algorand demonstrates up to 12,000 TPS without downtime Gartner; Hedera Hashgraph — up to 10,000 TPS with finality in 3–5 seconds Informa TechTarget.
Security 💥
Ethereum PoS: in Q1 2025 the share of slashing among Figment validators was 0%, participation — 99.9% Figment; among Coinbase validators — 99.75% The Coin Republic.
Bitcoin remains the benchmark for attack protection, recognized as the "digital Fort Knox" even at the level of state reserves Reuters.
Decentralization 🐳
Ethereum — approximately 1,050,000 active validators, in 2025 their number increased by 7% YoY Medium; after Bitcoin, it is considered the most decentralized of smart contract networks Medium.
Algorand and Hedera have significantly fewer validator nodes, which potentially reduces the level of decentralization.
Ecosystem and developers 🚂
Ethereum — the largest developer community: growth in the number of "long-term" developers by 21% in 2024 Medium; 24,000 active developers monthly Developer Report.
TVL in DeFi on Ethereum > $35 billion, while competitors (Solana, Avalanche) are several times less The Data Scientist.
Economic power 🤖
Ether (ETH) — the 2nd largest cryptocurrency by market capitalization after Bitcoin CoinLedger; high liquidity on all major exchanges.
Bitcoin — 1st in market capitalization, but limited to the function of "digital gold."
Roadmap and development 👽
Pectra upgrade is scheduled for May 7, 2025, it will enhance L1 scalability CoinDesk.
Ethereum Foundation shifts focus to UX and L1 scaling cryptoapis.io.
The gradual transition to "The Purge" and "Verkle Trees" optimizes data storage.
Conclusion and recommendation 🎁
Ethereum — the best choice "in every respect" thanks to the balance of security, decentralization, scalability, and the most powerful ecosystem.
Bitcoin remains the king of security and decentralization, but is poorly suited for smart contracts and DeFi.
Algorand is ideal where extreme speed and reliability are needed without a single downtime.
Hedera Hashgraph is suitable for business solutions with guaranteed SLA.
If you need the most versatile, developed, and supported platform with all kinds of dApps, DeFi protocols, and future upgrades — Ethereum remains the undisputed leader.
