Newbie On Chain: A transaction is a message that is sent from one account to another account. It can include binary data and Ether. If the target account contains code, that code is executed and the payload is provided as input data. If not, the transaction creates a new contract. The output of this execution is permanently stored as the code of the contract. This means that in order to create a contract, you do not send the actual code of the contract, but in fact code that returns that code when executed.
Quick Fact of EVM: The Ethereum Virtual Machine is the runtime environment for smart contracts in Ethereum. It is not only sandboxed but actually completely isolated, which means that code running inside the EVM has no access to network, filesystem or other processes. Smart contracts even have limited access to other smart contracts. There are two kinds of accounts in Ethereum: External accounts and contract accounts, and the two types are treated equally by the EVM.
Newbie On Chain: A blockchain is a globally shared, transactional database. Any change in the database are accepted by all others simultaneously. On blockchain, everyone has a synchronized account book, which makes a centralized ‘bank’ no longer necessary. The transactions will be encrypted by hashing, bundled into a “block”, and distributed among all others. These immutable blocks form a linear sequence--the so-called “blockchain” and exist permanently.
Newbie On Chain: Ethereum is referred as a series of contracts defining decentralized apps. Smart contracts are used in ETH: they are collections of code (functions) and data (state) that resides at a specific address on the Ethereum blockchain. By building contracts on EVM, users can create cryptocurrency, process transaction, build new ‘ecosystem’, etc. Moreover, all traces will be permanently embedded on chain, which costs certain amount of price (GAS) in return to maintain the whole ETH system.
