**XELIS** is an innovative cryptocurrency built from scratch in Rust Language with BlockDAG, Homomorphic Encryption, Zero-Knowledge Proofs, and Smart Contracts. This allows Xelis to combine fast transaction speed, privacy, and utility all onto it's Layer 1.

**Main Features:**

**BlockDAG** is used to improve the scalability and the security of the network.Instead of choosing between two chains, BlockDAG merges both chains into one.

**Homomorphic Encryption** is enabled using Twisted ElGamal to provide privacy on transactions (transferred amounts) and balances. ElGamal cryptosystem was chosen because it's a well known and studied encryption algorithm which has homomorphism features. ElGamal is used in combination with the Ristretto255 curve to provide a good level of security (~128 bits of security). Homomorphic operations available using ElGamal are addition/subtraction between ciphertexts and/or plaintext and multiplication against plaintext value.

**Account Model** (instead of UTXO like Bitcoin) was chosen in order to be faster, smaller, and easier for everyone. It allows to have a more flexible system than UTXO model and to have a better privacy because there is no need to link inputs and outputs, which provide real fungibility. It also enables the fast-sync feature to only download the last state of the chain instead of downloading all its history.

**Pruning system** is available to reduce the size of the blockchain by removing old blocks and transactions.

**P2p Encrypted Network** is used to prevent any network traffic analysis and to provide better privacy. All messages between nodes are encrypted with ChaCha20-Poly1305. Messages keys are rotated every GB of data.

**Smart Contracts** are not yet available on mainnet, but progress is being made towards their development. Please see Xelis github for latest status
