Solidity enables developers to define and implement the logic of their smart contracts in a secure and efficient manner. It features object-oriented programming principles, making it easier for developers to structure and organize their contract code.
Characteristics of smart contracts
Smart contracts on Ethereum possess several key characteristics. They are deterministic, meaning that given the same input, they will produce the same output every time. They are also immutable, as once deployed on the blockchain, the code and logic of the smart contract cannot be altered. This immutability ensures that contracts remain tamper-proof and reliable. Additionally, smart contracts are transparent, allowing anyone to verify the code and the terms of the contract. Finally, smart contracts are self-executing, automatically enforcing the agreed-upon terms without the need for intermediaries.
DAO event and Ethereum split
In 2016, the Decentralized Autonomous Organization (DAO), built on Ethereum, experienced a major security vulnerability. This vulnerability allowed an attacker to exploit the smart contract, resulting in the loss of a significant amount of Ether. To rectify the situation, the Ethereum community decided to hard fork the network. This decision ultimately led to the creation of two separate blockchains: Ethereum (ETH), which continued on the original chain, and Ethereum Classic (ETC), which remained on the unforked chain. This event highlighted the importance of secure coding practices and the need for community consensus in handling such incidents.
Incentivization in Ethereum
Running the protocol through Ether
The Ethereum network relies on a proof-of-work (PoW) consensus mechanism, similar to Bitcoin, to validate and verify transactions. Miners, who participate in the network, use their computational power to solve complex mathematical problems and secure the network. In return for their efforts, miners are rewarded with Ether. This incentivization model ensures that the network remains secure and encourages individuals to contribute their computational resources to the Ethereum ecosystem.
Motivation for individuals to participate
There are various motivations for individuals to participate in the Ethereum network. Miners, in addition to receiving rewards in the form of Ether, also benefit from transaction fees paid by users for their transactions to be prioritized.
