Let's review what we've learned about blockchain transactions and put your knowledge to the test!
📚 What You've Learned
Understanding UTXO (Bitcoin) vs Account-based (Ethereum) transaction models and their trade-offs
The anatomy of a transaction: from/to addresses, value, gas limit, gas price, nonce, and signatures
How nonces prevent replay attacks, ensure ordering, and enable transaction replacement
Step-by-step process from creating a transaction to broadcasting and confirmation
🔑 Critical Concepts
Either everything succeeds or everything fails - no partial transactions
Even if a transaction fails, gas fees are paid to validators for computational work
Transaction with nonce 5 won't process until nonce 4 is confirmed - no gaps allowed
Private key creates signature, public key verifies it - proves you own the sending address
Every transaction has a unique hash (TXID) that identifies it on the blockchain forever
