Topic: [ANN] DERO: DAG + Cryptonote + Bulletproofs + SSL + POW + Smart Contracts - page 14. (Read 123190 times)

...

• Are bullet proofs only a faster way to do ring signatures (which is amazing!) or is there something else additionally?
• Impressed with your DAG implementation to eliminate forking and speed up block times.  Why is it still 2 minutes until tx finality if you've eliminated soft forking?
• How do you resolve conflicting txs in the DAG?  What rule do you use?  Do you put a total order on the blocks and take the first tx? I gues that would not work.  Or do you simply revoke any tx that has a double spend, in which case that would explain why there's no finality for 2 minutes?
• How many uncles are allowed and for how long can another block be added?
• Does Dero have RingCT?
• Do you have plans for a POS of BTF consensus or will it always be POW?

Excellent work again and thanks for answering any of these questions.

DERO Introduction
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 blockchain has the following salient features
DAG Based : No orphan blocks, No soft-forks
12 Second Block time: Extremely fast transactions and 2 minutes confirmation time
SSL/TLS P2P Network
CryptoNote : Fully Encrypted Blockchain
BulletProofs: Zero Knowledge range-proofs.
Fully Auditable Supply: Supply is fully auditable.
Ring signatures
Written from scratch: Almost everything has been implemented from scratch.

DAG
DERO DAG implementation builds outs a main chain from the DAG network of blocks which refers to main blocks (100% reward) and side blocks (67% rewards). Side blocks contribute to chain PoW security and 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.
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.

Crypto
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. Optimized 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 1 , 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.
Further research/studies/optimizations are in-progress to further improve DERO network.

Thanks for your patience and support.

You can launch the derod with the flag "--badgerdb" or use the latest GUI wallet from github : https://github.com/deroproject/dero_gui_wallet/releases

Hello, any solutions to sync wallet faster in HDD? Because, i heard that new wallet was created for SSD.

You ruin everything Capt. You had a great team and great community but you let your greediness lead you and Dero project to a disaster. Still so disapointed.

They just promise that the premined coins are locked within a period.
They can do anything with the premined coins once the time limit expired, either sell them little by little or dump to the bottom.

Is it actually possible to mine this coin with a simple laptop? Even if it's not profittable, could it make sense if the price in future will shine? I really believe in this coin

YES HELLO TO ALL OF MY FELLOW CRYPTONIGHT MINER. I would just like to inform you of a brand new pool @ http://142.93.176.17/dero/ with over 30 blocks found head on over for a zero% mining fee while it lasts.
THANKS AGAIN
