Solidity, is a programming language specifically designed for developing smart contracts on blockchains compatible with the Ethereum Virtual Machine (EVM), standing out as the cornerstone for the development of dapps (decentralized applications). In this post, we will explore its essence, its connection to EVM networks, and how this language has triggered a new era of smart contracts, transforming the way we conceive and execute agreements in the decentralized landscape.
Origins of Solidity:
The birth of Solidity dates back to the early days of Ethereum in 2014. Its genesis is attributed to Gavin Wood, a key programmer on the founding team of Ethereum. At that time, the growing popularity of cryptocurrencies and decentralization posed a fundamental question: How could we translate complex agreements and transactions into executable code on the blockchain?
Gavin Wood, recognizing this critical need, embarked on the task of creating a programming language that could address the specific challenges of smart contracts. Thus, Solidity was born, designed from its foundations to facilitate the programming of business rules in a secure and efficient manner.
In its early stages, Solidity focused on providing developers with a familiar syntax, inspired by languages like JavaScript and C++, to ease the transition and rapid adoption. The vision was clear: to enable anyone with programming knowledge to participate in the smart contract revolution.
As Ethereum solidified its position as one of the leading blockchain platforms, Solidity became essential to its ecosystem. Its evolution did not stop, and contributions from the community and the development team ensured that the language adapted to the changing demands and challenges of the blockchain space.
Hoy en día, Solidity no solo es un lenguaje de programación; es la columna vertebral de innumerables aplicaciones descentralizadas (dApps) y contratos inteligentes que impulsan la interoperabilidad y la confianza en la cadena de bloques. Desde sus modestos orígenes hasta su papel central en el panorama blockchain, Solidity sigue siendo un testimonio del impulso constante hacia la innovación y la accesibilidad en el mundo de la programación para contratos inteligentes.
Solidity y Ethereum Virtual Machine (EVM): Explorando la Simbiosis Fundamental
Solidity, created by Gavin Wood in 2014, is not just a programming language; it is the catalyst that links Ethereum’s ambitions with the execution of smart contracts. Its history is intrinsically intertwined with the Ethereum Virtual Machine (EVM), the virtual machine that executes these contracts on the Ethereum blockchain.
The connection between Solidity and EVM is crucial to understanding how smart contracts take shape and come to life on the network. Ethereum Virtual Machine acts as the execution engine, interpreting and carrying out the code written in Solidity. This symbiotic relationship is what enables developers to create business rules, programmable logic, and automated agreements securely and reliably.
EVM, essentially, is a Turing-complete virtual machine that executes smart contracts using bytecode. Solidity, on the other hand, acts as the linguistic bridge between developers and this virtual machine. Contracts written in Solidity are compiled into bytecode that EVM can understand and execute. This abstraction allows even those without a deep understanding of the internal workings of EVM to participate in the creation of smart contracts.
The Solidity-EVM relationship has proven to be the foundation of the smart contract revolution on Ethereum. It enables reliable and decentralized execution of agreements, eliminating the need for intermediaries and providing transparency to transactions. Thus, Solidity not only simplifies the development of smart contracts but also opens the doors to a new paradigm of trust and efficiency in the blockchain realm.

Example of a Basic Smart Contract in Solidity: An Initial Look
In this example, we will create a more advanced contract representing a greeting token. This contract will allow users to send personalized greetings and keep track of how many greetings they have sent. Additionally, we will incorporate the OpenZeppelin library to ensure the contract’s security.
