Merkel Tree & Gas Limit

What is the structure of a Merkel Tree?

• Linked list structure with leaf nodes as hashes of data blocks

• Binary tree structure with leaf nodes as hashes of data blocks and non-leaf nodes as hashes of child nodes' hashes

• Array structure with leaf nodes as hashes of data blocks

• Graph structure with leaf nodes as hashes of data blocks

How is hashing used in a Merkel Tree?

• Hashing is used to encrypt the data stored in a Merkel Tree.

• Hashing is used to sort the nodes in a Merkel Tree.

• Hashing is used to compress the data in a Merkel Tree.

• Hashing is used to combine the hashes of child nodes to create the hash of the parent node in a Merkel Tree.

What is the Gas Limit in Ethereum?

• Minimum amount of gas that can be spent on a transaction

• Total gas used in a block

• Maximum amount of gas that can be spent on a transaction

• Gas price for a transaction

Why is the Gas Limit important in Ethereum transactions?

• To ensure transactions have enough gas to complete all necessary computations and prevent them from failing due to insufficient gas.

• To determine the recipient of the transaction

• To increase the transaction fees for miners

• To limit the number of transactions that can be included in a block

How is the Gas Limit adjusted in Ethereum?

• Gas Limit is adjusted by a smart contract.

• Miners adjust the Gas Limit through a voting mechanism.

• Gas Limit is set by the Ethereum Foundation and cannot be changed.

• The Gas Limit is adjusted automatically based on network activity.

Explain the concept of Merkel Tree in blockchain technology.

• A Merkle Tree is a type of cryptocurrency

• A Merkle Tree is a type of smart contract in blockchain technology

• A Merkle Tree is a data structure used in blockchain technology to efficiently verify the integrity and consistency of data stored in the blockchain.

• A Merkle Tree is used to store user passwords securely

What role does hashing play in the construction of a Merkel Tree?

• Hashing encrypts the data nodes in a Merkel Tree

• Hashing is used to sort the data nodes in a Merkel Tree

• Hashing is not relevant to the construction of a Merkel Tree

• Hashing generates unique hash values for data nodes and combines them to create parent nodes in a Merkel Tree.

Why is the Gas Limit necessary for executing transactions on the Ethereum network?

• To specify the maximum amount of gas that can be consumed by a transaction and prevent infinite loops or out-of-control computations.

• To limit the number of transactions that can be processed simultaneously

• To determine the sender of the transaction

• To increase the cost of executing transactions

What happens if the Gas Limit is set too low in an Ethereum transaction?

• The transaction will be processed faster

• The transaction will proceed as normal

• The transaction may fail and be reverted.

• The Gas Limit will automatically increase

How does the Gas Limit impact the security and efficiency of the Ethereum network?

• The Gas Limit impacts the security and efficiency of the Ethereum network by influencing the mining difficulty

• The Gas Limit impacts the security and efficiency of the Ethereum network by setting the maximum computational work that can be done in a block, affecting transaction complexity and network congestion.

• The Gas Limit impacts the security and efficiency of the Ethereum network by regulating the number of nodes in the network

• The Gas Limit impacts the security and efficiency of the Ethereum network by determining the price of Ether
