Smart contracts on Ethereum
With this tutorial you will be able to take your first steps in the development of smart
contracts on the Ethereum BlockchainX platform. With a simple example we will see
how a contract is written, how it is deployed, how it is instantiated in your own private
Ethereum network and, most importantly, how it is executed.
1. Introduction
Blockchain technology is still a path in which there is much to explore and discover, but
today we can already do interesting things with it apart from speculating with
cryptocurrencies. Bitcoin led the way by allowing the exchange of cryptocurrency in a
secure and decentralized manner. Ethereum goes further and can be considered as a
second generation blockchain implementation in which the idea of exchanges between
parties is generalized.
1.1. blockchain
In this tutorial I am not going to explain the details of what a blockchain is and how it
works. However, being surely the most important concept of all this technology, I am
going to comment on what is going on for those who are still not clear about it.
1.2. Ethereum
In general terms, Ethereum is defined as a decentralized blockchain contract
execution platform with no trusted authority (zero trust). Contracts are scripts that define
processes from simple cryptocurrency exchanges like Bitcoin does to complex policies
that are triggered by events. Contracts work on tokens, which determine who participates
in a contract and with how much value.
1.3. smart contracts
A normal contract specifies an agreement between parties with actions and conditions of
performance. A contract becomes “smart contract migration” when it includes code and
logic that execute actions and enforce conditions, that is, code that enforces the contract
without the need for manual intervention by either party. The most interesting thing
beyond that supposed “intelligence” is that the contract is executed within the network, in
the Ethereum
Virtual Machine (EVM).
This execution is not free but is paid in the form of “gas”, a small amount of
ether currency contributed by one or more of the participants in the contract. An
important detail is that the execution is decentralized but not distributed, which
means that it occurs in all the nodes of the network. The contract is developed in a
specific language (Solidity, Serpent or Mutan), is compiled to EVM and, with few
exceptions, complies with a standard interface called ERC20.
