Ethereum new language

Another Solidity alternative is Vyper. It is statically typed, safe, Pythonic approach. Vitalik was pushing Vyper quite hard for a while, but he seems to have ramped that down. I wonder if Vyper is in any way better than Solidity. The Ethereum foundation stopped supporting the project.

What Programming Language is Ethereum Written In?

We probably started hearing about Blockchain almost a decade ago when someone under the pseudonym of Satoshi Nakamoto released the first Bitcoin reference implementation. If you ever wonder who Satoshi is, you are not alone, and I am pretty confident it's a secret; nobody will reveal it in the years to come. Bitcoin not only introduced a digital currency as we know it today but also made popular the theory behind one of the most important inventions in the last decade, Blockchain technology.

But what is Blockchain exactly? We will try to give a definition leaving all the fuzzwords behind. A Blockchain represents a distributed ledger of transactions running in a peer-to-peer network, where those transactions, once confirmed, can not be deleted or modified. The image above gives a visual representation of the Blockchain so you can grasp the concept. We can see it as transactions grouped in blocks, which are chained together. The chain is a logical pointer from one block to the previous one.

As it would happen with any peer-to-peer network you might use in the past for sharing files, the same concepts apply to Blockchain. It does not have any central authority or server, and all the participants in the network replicate the ledger of transactions. The participants who join the network for submitting transactions or reading data from the ledger are known as Nodes. Last but not least important, most Blockchains are public, making the information on them available on-demand for everyone and representing a single source of truth.

Transactions and blocks are the first citizens of any Blockchain. Transactions are atomic operations that modify the state of the ledger. Any user or application is free to join the network and submit transactions, which are later broadcast to other nodes for validation and execution. Those transactions can be executed in different manners depending on the Blockchain they run. For example, Bitcoin primarily allows transactions to transfer funds between accounts. It supports scripting, but it is limited.

Ethereum, on the other hand, and as we will see later in this article, enables transferring funds and running programs. We can not finish this topic without mentioning one of the common denominators for all the Blockchain implementations, Public Key Cryptography PKI. A pair of private and public keys gives us the ability to send and receive transactions in a Blockchain network.

We use private keys to sign transactions before submitting them to the Blockchain. On the other hand, we can derive public keys from a private key and share them with other users or applications to receive transactions.

As public keys represent a chunk of bytes, it becomes difficult for us to share them. For that reason, every Blockchain uses different encoding techniques and algorithms to convert them first in a user-friendly string.

That encoded string is called "Address". We can not simply send arbitrary transactions to a Blockchain; we also need to have tokens associated with our private key for paying that cost. Now it is time to ask yourself the following question; how can I get tokens in the first place to start operating in a Blockchain? Like any country in the world that uses a Treasury Department for printing fiat currency, Blockchain relies on particular nodes, the Miners, for token emission.

Miners run a decentralized strategy known as "Mining," which consists of validating transactions, grouping them in blocks, and adding those to the ledger. It's expensive in terms of energy consumption. For that reason, Miners get paid by collecting fees and rewards issued by the network in small coin fractions after they successfully add blocks to the ledger.

However, before doing anything, Miners must ensure they will get that pay. That's where a particular transaction called "Coinbase" enters the scene. A "Coinbase" is no other thing than a check, pointing to a Miner's public address.

If a miner could speak, they would say, "I did my job already, so pay me here. The chicken and egg dilemma. If a Miner wants to get paid for committing blocks into the ledger, how do they get paid when a Blockchain network starts running and no tokens are available? The secret is on the rewards or tokens issued by the network. The first blocks committed to any Blockchain only have Coinbase transactions, which pay Miners with rewards.

Miners later transfer those funds to other users, making tokens start flowing through the network. What I said before about tokens being associated with a private key is technically correct, but not how it works in real life. Tokens never leave the Blockchain. Instead, they are associated with a pointer to public addresses. Since those public addresses can only be derived from your private key, that is how you prove the tokens belong to you.

The same thing happens when you want to pay for a transaction or transfer tokens. The private key that you use for signing the transaction is also used to derive the public keys where the tokens are.

Adding blocks to the ledger requires coordination between all the Miners in the network. To make it worse, remember that Miners also compete with each other for fees and rewards. If any Miner could add blocks at discretion, the value of the Blockchain would be 0. In real life, any Blockchain runs a distributed protocol, known as Consensus protocol, that governs Miners and determines how and when they can push blocks in the ledger. Bitcoin introduced a variant of the protocol called "Proof of Work", but there are many others.

Ethereum, for instance, was launched with the exact implementation, but it is transitioning to "Proof of Stake" in the short term with a new rollup called Ethereum 2. We will discuss these two variants more in detail in the following sections. Proof of work relies on computer processing to resolve complex mathematical problems. When a Miner generates a block with transactions, it also includes a hash computed from the binary representation of the transactions, a random nonce value a set of bytes , and the previous block's hash.

That makes the Blockchain resistant to changes. If a Miner wants to change a transaction in one block, it must also regenerate the hash in all the previous blocks, making this practically impossible. The hash for the block must follow a particular pattern to be added by the Miner into the ledger. That is where the mathematical problem enters the scene. The Miner must vary the Nonce and recalculate the hash multiple times until it gets one that matches the pattern.

The first Miner that accomplishes this task is allowed to submit the block to the ledger. Other miners validate the block's hash and make sure it is correct. Once the block is validated, the Miner gets paid. The major problem with the Proof of Work protocol is energy consumption, which led many working groups in Blockchain to start looking into less expensive alternatives. That is how "Proof of Stake" came into the picture.

As a starter, this protocol introduces an entry barrier for miners. They must put a certain number of tokens at stake to become miners or validators, as they are called in this protocol. In Ethereum 2. Those who don't meet that requirement can still share tokens with stake pools created for that purpose.

The stake pool ends up running the Miner or Validator. In terms of implementation, this protocol lets validators push blocks in the ledger based on a ranking determined by the number of tokens at stake and reputation over time. That ranking can be affected by bad decisions or when a node fails to validate transactions e.

A wallet is another term we will often see in Blockchain. It's an application that allows end-users to create and persist private keys and derive public keys or addresses from them. It is not equivalent to a real-world wallet as it does not store funds cash or credit cards but only the private key that acts as a pointer to your tokens in the Blockchain. If the private key is lost or compromised, the same thing will happen with the tokens; you will not be able to claim any.

You can find two types of wallets, deterministic and non-deterministic. The main difference is that determinist wallets allow you to recover a private key from a seed. That seed is no other thing than a pass-phrase or a set of words that you write down and keep safe in an offline medium like a piece of paper. If the private key is lost, you can still recover it from the seed. That will not happen with a non-deterministic wallet.

If you lost the private key, there is no way you could recover it. It could be web wallets, mobile wallets, or even hardware wallets. Wallets that don't give you direct access to your keys are known as "custodial wallets". Exchanges for buying crypto are an example of this. There is often a phrase associated with this type of wallet, "it is not your keys, not your coins. Ethereum is a Blockchain conceived by Vitalik Butarin, Martin Wood, and other members in and released in They wanted to address different limitations present in Bitcoin and especially allow the execution of short programs in the Blockchain.

While Bitcoin was focused on decentralized payments, Vitalik and the rest of the team were looking for better ways to build decentralized finance systems with apps running in the Blockchain.

They released an initial proposal that allowed users or applications to push arbitrary code in the Blockchain using transactions. That was the first time the concept of Smart Contracts or contracts in short was mentioned. A Smart Contract is a short program that can be deployed and run on a Blockchain. In other words, you can see it as a state machine running in the Blockchain with a public address where you can push or pull the state.

Those transactions can pass both funds and data. For example, a smart contract for sports betting. Every node in the network runs this VM, and it is ready to execute any arbitrary code.

Creating a new contract in the Blockchain implies sending the program representation in byte code as part of the transaction data payload.

Rust-based language surges as a feasible alternative to Solidity for Ethereum contracts

Ethereum is considered to be the most sensible and sustainable cryptocurrencies of them all. There is a long-term scope and usage of this cryptocurrency and that is why the price of this system is zooming just like Bitcoin. Technically speaking, Ethereum is an open source yet blockchain based system that functions with smart contact. Ethereum is not really a cryptocurrency but a computing platform. The cryptocurrency created based on this platform is Ether. If you are comparing with Bitcoin, you should compare with Ether and not Ethereum. Therefore, you can understand that it is somewhat bigger than Bitcoin in its scope and development.

Ethereum Smart Contracts with Solidity: Features of the Solidity Language

RELATED VIDEO: Intro To Ethereum Programming [FULL COURSE]

The software engineer Christoph Burgdorf presented a new programming language for the Ethereum ecosystem, called Fe this October It surges as a very good alternative to Solidity, the main programming language on which smart contracts are encoded and the most decentralized applications on the network. In a post on the Ethereum Developer Blog, Burgdorf explains that even though he believes the Solidity team is doing a great job, he sees a need for developers to have more options for smart contract encoding. Burgdorf adds that the initial idea with the Vyper rewrite was to have an alternative compiler. However, along the way, substantial differences emerged from Vyper that led to a different language, which he decided to call Faith.

Solidity 0. For all details please refer to the release announcement here. As a relatively young language, Solidity is advancing at a rapid speed. We aim for a regular non-breaking release every weeks, with approximately two breaking releases per year. You can follow the implementation status of new features in the Solidity Github project.

Vyper lets you program on Ethereum , a blockchain-based virtual machine that allows the creation and execution of smart contracts, without requiring centralized or trusted parties. It was designed to improve upon Solidity, another smart contract language for Ethereum, by limiting unsafe practices and enhancing readability; Vyper seeks to optimize the security and auditability of smart contracts. Vyper is an experimental, statically typed, contract programming language meant to resemble Python.
