Radix vs Ethereum

Q: What is Consensus?

Ethereum uses Casper PoS with a single execution layer processing all transactions sequentially. Scalability relies on L2 rollups (Optimism, Arbitrum, zkSync) which introduce sequencer centralization and cross-rollup composability challenges. Radix uses Cerberus, which parallelizes consensus across

Q: What is Programming Model?

Ethereum (Solidity): Account-based model where tokens are mappings inside contracts. Requires approve() + transferFrom() pattern. Susceptible to reentrancy, approval exploits, and front-running. Radix (Scrypto): Asset-oriented model where tokens are native resources. No approval pattern. Reentrancy

Q: What is Transactions?

Ethereum: Opaque calldata — users blind sign hex data they can't read. Radix: Transaction manifests — readable, composable, verifiable before signing.

Q: What is Strengths of Each?

Ethereum's strengths: Largest ecosystem, most liquidity, widest tooling support, strongest brand recognition, battle-tested over 10+ years. Radix's strengths: Superior asset model (native assets, no approvals), readable transactions, linear L1 scalability, developer-friendly Rust-based language, str

Consensus

Ethereum uses Casper PoS with a single execution layer processing all transactions sequentially. Scalability relies on L2 rollups (Optimism, Arbitrum, zkSync) which introduce sequencer centralization and cross-rollup composability challenges.

Radix uses Cerberus, which parallelizes consensus across shards. Throughput scales linearly with shard count. 500,000+ TPS demonstrated on commodity hardware.

Programming Model

Ethereum (Solidity): Account-based model where tokens are mappings inside contracts. Requires approve() + transferFrom() pattern. Susceptible to reentrancy, approval exploits, and front-running.

Radix (Scrypto): Asset-oriented model where tokens are native resources. No approval pattern. Reentrancy structurally impossible. Assets move in buckets.

Transactions

Ethereum: Opaque calldata — users blind sign hex data they can't read.

Radix: Transaction manifests — readable, composable, verifiable before signing.

Scalability

Property	Ethereum	Radix
L1 TPS	~15-30	500,000+ (Cerberus)
Scaling approach	L2 rollups	L1 sharding
Cross-shard composability	Async bridges	Atomic (same-transaction)
Hardware requirements	Moderate (L1), centralized (L2 sequencers)	Commodity

Strengths of Each

Ethereum's strengths: Largest ecosystem, most liquidity, widest tooling support, strongest brand recognition, battle-tested over 10+ years.

Radix's strengths: Superior asset model (native assets, no approvals), readable transactions, linear L1 scalability, developer-friendly Rust-based language, structurally eliminates common exploit classes.
