Block
Blockchain Block
Collection of transactions bundled together on a blockchain
Definition
A block is a collection of transactions that are bundled together and added to the blockchain. Each block contains a cryptographic hash of the previous block, creating an immutable chain.
Block (Blockchain Block) is a technical term used to understand Collection of transactions bundled together on a blockchain. In practice, it matters because it affects how users evaluate protocols, compare opportunities, and avoid hidden assumptions.
Example
An Ethereum block contains multiple transactions and is produced approximately every 12 seconds.
How it works
In practice, the concept shows up like this: An Ethereum block contains multiple transactions and is produced approximately every 12 seconds.
Why it matters
Block matters because small misunderstandings in DeFi can turn into bad pricing, liquidation, governance, custody, or smart-contract risk. A good mental model helps you compare protocols without relying on marketing language.
What to check
Treat it as infrastructure: understand what it automates, what trust assumptions remain, and how failures propagate. The main checks are: Block reorganization; Confirmation delays; Network forks.
Risks to Consider
- Block reorganization
- Confirmation delays
- Network forks
Common Questions
How many confirmations do I need?
For high-value transactions, wait for 6+ confirmations on Ethereum. For smaller amounts, 1-3 confirmations are usually sufficient.
What does Block mean in DeFi?
Block means Collection of transactions bundled together on a blockchain. The useful question is not only the definition, but how the mechanism changes risk, return, liquidity, or governance for the user.
How is Block used in practice?
A practical example: An Ethereum block contains multiple transactions and is produced approximately every 12 seconds.
