This interactive blockchain simulation allows you to create transactions, mine new blocks, and explore the mechanics behind blockchain technology. Experiment with different mining difficulties and see how cryptographic hashing secures the entire system.
The blockchain below represents a series of connected blocks. Each block contains transactions and is cryptographically linked to the previous block through its hash. Click on any block to view its details.
Pending transactions are waiting to be included in the next block. When you mine a new block, all pending transactions will be added to the blockchain.
| From | To | Amount | Timestamp |

Create a new transaction that will be added to the pending transactions pool. In a real blockchain, these transactions would be signed with your private key to prove authenticity.
In actual blockchain networks, each transaction is secured by a digital signature created with the sender's private key. This signature can be verified using the sender's public key to ensure the transaction is authentic.
