DERO is decentralized DAG(Directed Acyclic Graph) based blockchain with enhanced reliability, privacy, security, and usability. Consensus algorithm is PoW based on original cryptonight. DERO is industry leading and the first blockchain to have bulletproofs, TLS encrypted Network.
DERO is the first crypto project to combine a Proof of Work blockchain with a DAG block structure and wholly anonymous transactions based on CryptoNote Protocol. The fully distributed ledger processes transactions with a twelve-second average block time and is secure against majority hashrate attacks. DERO will be the first CryptoNote blockchain to have smart contracts on its native chain without any extra layers or secondary blockchains. At present DERO have Smart Contracts on testnet.
Secure and fast crypto is the basic necessity of this project and adequate amount of time has been devoted to develop/study/implement/audit it. Most of the crypto such as ring signatures have been studied by various researchers and are in production by number of projects. As far as the Bulletproofs are considered, since DERO is the first one to implement/deploy, they have been given a more detailed look. First, a bare bones bulletproofs was implemented, then implementations in development were studied (Benedict Bunz,XMR, Dalek Bulletproofs) and thus improving our own implementation.
Some new improvements were discovered and implemented (There are number of other improvements which are not explained here). Major improvements are in the Double-Base Double-Scalar Multiplication while validating bulletproofs. A typical bulletproof takes ~15-17 ms to verify. Optimised bulletproofs takes ~1 to ~2 ms(simple bulletproof, no aggregate/batching). Since, in the case of bulletproofs the bases are fixed, we can use precompute table to convert 64*2 Base Scalar multiplication into doublings and additions (NOTE: We do not use Bos-Coster/Pippienger methods). This time can be again easily decreased to .5 ms with some more optimizations. With batching and aggregation, 5000 range-proofs (~2500 TX) can be easily verified on even a laptop. The implementation for bulletproofs is in github.com/deroproject/derosuite/crypto/ringct/bulletproof.go , optimized version is in github.com/deroproject/derosuite/crypto/ringct/bulletproof_ultrafast.go
There are other optimizations such as base-scalar multiplication could be done in less than a microsecond. Some of these optimizations are not yet deployed and may be deployed at a later stage.

Following are DERO first and leading innovations.
DERO DAG implementation builds outs a main chain from the DAG network of blocks which refers to main blocks (100% reward) and side blocks (8% rewards).

Traditional Blockchains process blocks as single unit of computation(if a double-spend tx occurs within the block, entire block is rejected). However DERO network accepts such blocks since DERO blockchain considers transaction as a single unit of computation.DERO blocks may contain duplicate or double-spend transactions which are filtered by client protocol and ignored by the network. DERO DAG processes transactions atomically one transaction at a time.
Dero ultrafast bulletproofs optimization techniques in the form used did not exist anywhere in publicly available cryptography literature at the time of implementation. Please contact for any source/reference to include here if it exists. Ultrafast optimizations verifies Dero bulletproofs 10 times faster than other/original bulletproof implementations. See: https://github.com/deroproject/derosuite/blob/master/crypto/ringct/bulletproof_ultrafast.go
DERO rocket bulletproof implementations are hardened, which protects DERO from certain class of attacks.
DERO rocket bulletproof transactions structures are not compatible with other implementations.
Also there are several optimizations planned in near future in Dero rocket bulletproofs which will lead to several times performance boost. Presently they are under study for bugs, verifications, compatibilty etc.
DERO DAG implementation builds outs a main chain from the DAG network of blocks which refers to main blocks (100% reward) and side blocks (8% rewards). Side blocks contribute to chain PoW security and thus traditional 51% attacks are not possible on DERO network. If DERO network finds another block at the same height, instead of choosing one, DERO include both blocks. Thus, rendering the 51% attack futile.
DERO is written in golang and very easy to install both from source and binary.

Download DERO binaries for ARM, INTEL, MAC platform and Windows, Mac, FreeBSD, OpenBSD, Linux etc. operating systems.
Most users required following binaries:
Windows 7-10, Server 64bit/amd64
Contact for support of other hardware and OS.
Running DERO daemon supports DERO network and shows your support to privacy.
Run derod.exe or derod-linux-amd64 depending on your operating system. It will start syncing.
Dero cmdline wallet is most reliable and has support of all functions. Cmdline wallet is most secure and reliable.
DERO cmdline wallet is menu based and very easy to operate.
Use various options to create, recover, transfer balance etc.
NOTE: DERO cmdline wallet by default connects DERO daemon running on local machine on port 20206.
If DERO daemon is not running start DERO wallet with --remote option like following:
Web Wallet runs in your browser, your seeds, keys etc. never leave your browser.

DERO blockchain is completely private, so anyone cannot view, confirm, verify any other’s wallet balance or any transactions.
So to prove any transaction you require Tx private key and receiver address.
Tx private key can be obtained using get_tx_key command in dero-wallet-cli.
Enter the Tx private key and receiver address in DERO EXPLORER
