What is Chia?
Chia was incorporated in August of 2017 to develop an improved blockchain and smart transaction platform. We are building the Chia Network to improve the global financial and payments systems. Chia is the first enterprise-grade digital money. Chia is using the first new Nakamoto consensus algorithm since Bitcoin. Called Proof of Space and Time, it was created by Bram Cohen, the best network protocol engineer alive and the inventor of BitTorrent. Chialisp is Chia’s new smart transaction programming language that is powerful, easy to audit, and secure. Reference smart transactions currently available are: atomic swaps, authorized payees, recoverable wallets, multisig wallets, and rate-limited wallets.

Where can I get answers to questions about running Chia?
You should first read the repository FAQ, check out the wealth of information on the repository wiki and join us on Keybase in the #testnet or #beginner channels. We have also created a good summary of the basics of creating plots for Chia.

What is Proof of Space and Time?

Proof of Space is a cryptographic technique where provers show that they allocate unused hard drive space for storage space. In order to be used as a consensus method, Proof of Space must be tied to Proof of Time. PoT ensures that block times have consistency in the time between them and increases the overall security of the blockchain.

How does Proof of Space and Proof of Time work?

Proof of space can be thought of as a way to prove that you are keeping some storage unused on your hard-disk drive. Users of the Chia blockchain will “seed” unused space on their hard-disk drive by installing software which stores a collection of cryptographic numbers on the disk into “plots.” These users are called “farmers.” When the blockchain broadcasts a challenge for the next block, farmers can scan their plots to see if they have the hash that is closest to the challenge. A farmer’s probability of winning a block is the percentage of the total space that a farmer has compared to the entire network.

Proof of time requires a small period of time to pass between blocks. Proof of time is implemented by a Verifiable Delay Function that takes a certain amount of time to compute, but is very fast to verify. The key idea of a VDF is that they require sequential computation, and since having many parallel machines does not yield any benefit, electricity waste is minimized. There will likely be relatively few VDF servers (“Timelords”), as the fastest one will always finish first and it takes only one fast and fair Timelord on the network to complete a block and move the chain forward.

What is Chialisp?

Chia has a newly developed, innovative blockchain programming language called Chialisp, which is powerful, easy to audit, and secure. Chialisp is a superior on-chain smart transaction development environment that will unlock the security, transparency, and ease of use that cryptocurrencies promise.
