A payroll decentralized application or peer to peer contract. ChainPact currently allows you to make two types of pacts: Gig pact or Proposal pact. Gig Pact allows anyone to create a freelancing or employment contract on the Blockchain. This is a time-based contract where the employer pays the agreed upon payment at the agreed upon intervals. The contract acts as an "escrow smart contract" for the payment. The Proposal pact smart contracts can also be used to create a fundraising campaign or kickstarter-type campaign on blockchain. It allows the creator of the smart contract to set a voting start time and duration. So contributors can choose to vote later on whether the funds are to be disbursed to the creator's account or to another account (e.g. refunded to them).

Polkadot, a blockchain network, is being built to enable Web3.0. This will allow users to control their data and ensure that markets benefit from network efficiency. Gavin Wood, a former co-founder and CTO at Ethereum, founded Polkadot in 2016. Polkadot's technology solves the major problems that have hindered blockchain adoption over the past few years. Parity Technologies created Polkadot's Substrate software development toolkit that allows blockchain developers to create their own custom, fit for use blockchains. Polkadot allows multiple blockchains to communicate with each other, allows for easy upgrades, and introduces "shared Security", a plug and play network security model that allows developers focus on the technology instead of spending time and resources recruiting operators to run a new Blockchain.

Clarity brings smart contracts and Bitcoin to life. It is a decidable programming language. This means you can predict the program's behavior from the code. Clarity is not compiled, but interpreted. The source code is available on the blockchain. Clarity provides developers with a safe way for them to create complex smart contracts on the most secure blockchain in the world. Clarity uses a precise and unambiguous syntax which allows developers to predict how their contracts will be executed. The Clarity language allows users the ability to specify their own conditions for transactions. This ensures that a contract will never unexpectedly transfer tokens owned by a user. Clarity contracts are broadcasted on blockchain exactly as developers wrote them. This ensures that developers only execute the code they have analyzed and tested.

Solidity is an ethereum-compatible programming language with curly braces that uses a statically typed syntax. Solidity is still a relatively new language. It is growing at a rapid pace. We aim to release a regular release (non-breaking release) every month with an average of one breaking release per calendar year. You can track the implementation status of the new features by visiting the Solidity Github Project. By switching from the default branch ("develop") to the "breaking branch", you can see what changes are coming for the next breaking release. Solidity can be actively shaped by your input and participation in the language design.

Vyper is an object-oriented, pythonic language that targets Ethereum Virtual Machine (EVM). Security: Vyper should make it easy and natural to create secure smart contracts. Language and compiler simplicity: Both the language and the compiler implementation must be simple. Auditability: Vyper should be as human-readable as possible. It should also be as difficult as possible to write code that is misleading. Simplicity is more important for the reader than for the writer. This is especially true for readers who have little or no experience with Vyper and programming in general.
