Is DERO Lying About Having Achieved Fully Homomorphic Encryption?
DERO claims to have achieved Fully Homomorphic Encryption but it's not possible without multiplication operations and without adequate proof.

One of the most exciting and ground breaking news about the DERO project is that they claim to have achieved Fully Homomorphic Encryption (FHE). Their recent proof of concept code release supposedly backs their claim.

What makes Fully Homomorphic Encryption full?
tl;dr: FHE means it can run both add and multiply operations

To understand whether DERO has achieved FHE or not, it’s important to know that there are three types of homomorphic encryption:
1. Partially Homomorphic Encryption (PHE)
2. Somewhat Homomorphic Encryption (SHE)
3. Fully Homomorphic Encryption (FHE)

FHE is considered the holy grail of security because it is capable of any number of addition and multiplication computations on your ciphertext (the result of encryption on your plaintext), thus making it very secure. However, because of how computationally intensive FHE is — it is widely considered impractical until recently with new advances in efficient schemes and technology by IBM, Microsoft and other developments.

PHE allows only either addition or multiplication to be performed on the ciphertext. This makes it very efficient and is already commonly used in security. It should be noted that PHE with multiplicative operations is the foundation for RSA encryption, which is commonly used in establishing secure connections through SSL/TLS.

SHE is one that supports select operation (either addition or multiplication) up to a certain complexity, but these operations can only be performed a set number of times.

DERO advertises its FHE claim everywhere, literally
So it must be 100% the truth! It’s shown on their website:

Their June monthly update:

Their July monthly update:

Their proof of concept code release:

And pretty much all of their tweets:

One DERO community member was diligent enough to ask the team from NuCypher (who is working on GPU-optimized FHE) about the code. And their response was that it isn’t FHE.

The NuCypher comment isn’t wrong to say that it looks like a homomorphic commitment scheme. Pederson’s commitment scheme is used in Monero, and it’s one of the features present in DERO codebase, as shown in their wiki:

What’s interesting is that NuCypher says that the DHEBP doesn’t prove FHE, and the wiki image of features only lists Additive Homomorphic Encryption. This is further supported by the DERO developer’s own comment:

The DERO developer acknowledges that full FHE can only be achieved if it can run multiplication operations, and removed multiplication operations for the sake of efficiency. The comment, in addition to the wiki list of features and the external review of the DHEBP is a clear admission that the proof of concept that supposedly claims to be FHE is infact only PHE.

So what do we know so far?
1. DERO developers are aware that their implementation is not FHE;
2. DERO developers continue to mention FHE in official materials;
3. DERO foundation heavily advertises “FHE as being achieved”; and

There is no mention of PHE being the actual implementation anywhere.

It seems that both the developers and foundation members are complicit in misleading the public that it has achieved FHE when in fact, it has only implemented PHE. Confusingly, it seems that DERO developers knew that they were going to pursue PHE all along. The github wiki was updated in December 2019 to add Additive Homomorphic Encryption to the list of technologies used.

Why they chose to be dishonest and claim FHE was achieved when PHE is a perfectly efficient technology to apply and has already been used heavily in cryptography is curious.

In choosing to be dishonest and misleading, it risks being labeled a scam, again.
Perhaps, the DERO developers have an explanation for why they are claiming to have achieved FHE in their new protocol inspite of having only addition operations. The burden of proof is on them to prove it through paper and explanation, which is the academic standard and norm. The explanation and the math supporting the code are as yet absent. Until these are adequately provided, it would be an argument based on ignorance to say that the burden of proof lies on the counter-party to prove DERO wrong.

How A Simple Timeline Of DERO’s Development Reveals Poor Management And Failure To Launch
Technology can only take you so far. Even when overselling the technology.

I have been following DERO for a long time. For a micro-cap cryptocurrency, I find it interesting how much potential a cryptocurrency can have, and yet make counter-intuitive decisions that stifle its own growth. Ultimately, even if the technology is groundbreaking, technologies can fail to become adopted or outmanuvered by compeition. If it cannot exercise proper project management, it may never launch at all, or fail to manage itself at a higher market cap.

Here is a brief look at the timeline of events and decisions they have made.

DERO Developer’s Team
Smart Contracts Platform
June 2019 Monthly Update: Target set for Q4 2019 for mainnet release of cryptonote-based smart contracts platform
August 2019 Monthly Update: Continued to assure that smart contracts will be in mainnet by end Q4 2019
January 2020 Monthly Update: New target set for Q2 2020 for mainnet release replacing cryptonote with new Fully Homomorphic Encryption implementation
June 2020 Monthly Update: Announcement of Fully Homomorphic Encryption implementation, with code to be released soon.
28 June 2020 Tweet: Proof of concept code release with no new timeframe of when testnet of new implmentation will happen or new target for mainnet release

Criticism
It’s clear to see that the DERO Developers do not follow any type of project management discipline or process. Delays are inevitable for any project, but DERO could have had DERO 1.0 with Cryptonote/DAG+ Smart Contracts, and then DERO 2.0 with AstroBWT/DAG/Fully Homomorphic Encryption + Smart Contracts. If Vitalik Buterin waited for ETH 2.0 to release into mainnet, do you think Ethereum would still be the worlds most valuable smart contracts platform?

DERO Foundation Team
It’s not clear what exactly the Foundation team does beside moderate their chat channels and work with Eric Jordan to create a new website and brand image.

Branding Initiative
January 2020 Monthly Update: Targeted “early” deployment in Q1 2020
March 2020 Monthly Update: Pushed to Q2 2020, which has now passed.

Criticism
A lot of the new “Branding Initiative” seems to be Eric Jordan’s responsibility, with the Foundation as project managers overseeing the changes. Why can’t they start marketing and rebranding before the new changes? Any new technology developments can always be integrated into the brand down the line. Are the developers and foundation members incapable of handling concurrent development and production cycles, which are the norm in virtually all projects?

DERO Education
August 2019 Monthly Update: No timeline, no clear indication that if any work has been done to date. Basic information from wikis and whitepapers still reflect outdated material.

Criticism
DERO Education is something that does not need to wait for any technology release. The earlier you start making it easy for people to learn about the technology, the more developers you can onboard before mainnet release. DERO disadvantags itself by using both their github and their private git site and making confusing to find information. Adding to that, their wiki could be much better detailed and their whitepaper is completely outdated at this point. This is also highlighted by a Dero Community Advisory Board (DCAB ) member, however it seems that DCAB is/has been inactive for some time- which is an indication of dwindling/stagnant community activity.


DERO Communication
1st April 2020 to 30th June 2020: No updates

The Foundation Team seems to be convicted in failing in their goal to communicate with the DERO community better in 2020 which they admitted to failing in their Annual Recap for 2019. Regular updates are important to ensure both Development and Foundation teams are working and making progress. Good communication makes people accountable and transparent in their actions, and this is especially important in crypto. DERO’s mantra is “Build it, and they will come”, but no one would dare enter a castle with no lights. And if there are no lights, why would anyone join and be in the company of ghosts?

To make matters worse, they have also pre-announced their intentions to either scale down or reduce usage of their use of Discord, which is their most used platform for releasing information outside of the Monthly Updates. Much of the announcements and “ breaking news” are first published in their Discord, and if not picked up by the Foundation to distribute through twitter and other means, would simply be buried in Discord chat.

Greetings,

The DERO team is pleased to announce the release of a unique homomorphic encryption scheme (DERO-HE) and the complete blockchain protocol (DHEBP) for public testing. DERO will migrate from the existing CryptoNote protocol to its own DERO Homomorphic Encryption Blockchain Protocol (DHEBP).


What Is Homomorphic Encryption?
Homomorphic encryption is a form of encryption allowing one to perform calculations on encrypted data without decrypting it first. The result of the computation is in an encrypted form, when decrypted the output is the same as if the operations had been performed on the unencrypted data.
Homomorphic encryption can be used for privacy-preserving outsourced storage and computation. This allows data to be encrypted and out-sourced to commercial cloud environments for processing, all while encrypted. In highly regulated industries, such as health care, homomorphic encryption can be used to enable new services by removing privacy barriers inhibiting data sharing. For example, predictive analytics in health care can be hard to apply via a third party service provider due to medical data privacy concerns, but if the predictive analytics service provider can operate on encrypted data instead, these privacy concerns are diminished.

About DERO Project

The DERO Project is aiming to create a platform for developers to deploy secure, open, scalable, and privacy-preserving decentralized applications. DERO is unique because we value security and privacy above all else; as a result, users are able to transact privately over our network without fear of common protocol-level and network attacks. Additionally, our technology preserves transparency where required and scales with network load, which provides an ideal environment for business-class applications.



First to implement Bulletproofs

TLS-encrypted network

Proof-of-Work DAG based Blockchain

Fully anonymous transactions based on Homomorphic Encryption

Secure against majority hashrate attacks

Homomorphic Encryption blockchain protocol with native and base-layer Smart Contracts

Competitive CPU mining based on the DERO AstroBWT algorithm

Public Testing

As with our previous releases, the full source code will be available for anyone wishing to build their own binaries. The public testnet will consist of two phases:

Phase 1: DHEBP

The initial testing phase will introduce the base layer protocol, DERO-HE, and many new features new to the blockchain space. Our aim is to extensively test the following:

Homomorphic account based model, a first for privacy-focused blockchains.

Instant account balances (only 66 bytes of data need to be read from the blockchain).

No more chain scanning or wallet scanning to detect funds, or the need for key images, etc.

Truly light-weight and efficient wallets.

Massive scalability improvements (fixed account cost of 66 bytes in the blockchain).

Perfectly anonymous transactions with Many-out-of-Many Proofs (Bulletproofs and Sigma Protocol) to support deniability.

Fixed transaction sizes of ~2.5KB (ring size or ~3.4 KB (ring size 16) based on chosen anonymity group size (in powers of 2), which have logarithmic growth.
+-----------+----------------+
| Ring Size |     TX Size    |
+-----------+----------------+
|     2     |   1553 bytes   |
|     4     |   2013 bytes   |
|     8     |   2605 bytes   |
|     16    |   3461 bytes   |
|     32    |   4825 bytes   |
|     64    |   7285 bytes   |
|     128   |   11839 bytes  |
|     512   |   ~35000 bytes |
+-----------+----------------+
Allows chain pruning on daemons to control data retention, while remaining secure using Merkle Proofs.

An example of disk requirements of 1 billion accounts (assuming one does not want to keep history of transactions, but retain all proofs to prove that the node is in sync with all other nodes).

Requirement of 1 account = 66 bytes

Assuming storage overhead per account of 128 bytes (constant)

Total requirements = (66 + 128) GB ~200 GB (assuming we are off by factor of 4 = 800GB)

Note: Even after 1 trillion transactions, 1 billion accounts will consume only 800 GB, and if history is not maintained, everything will be in proved state using Merkle Roots. As a result, even a Raspberry Pi can host the entire chain.

Transaction generation takes less than 25 ms.

No trusted setup, no hidden parameters.

Senders can prove to receiver what amount they have sent (without revealing themselves).

The entire chain is resyncable while in operation.

Phase 2: Stargate RC2

The next phase will include the DERO Virtual Machine (DVM) and Smart Contracts execution.

Allows homomorphic assets (programmable Smart Contracts with fixed overhead per asset), which will remain open, but any data within is encrypted (internal testing/implementation not included in this current testnet branch).

Hey I was just wondering if the KYC signature verification was implemented in the core code?

[Inagame]

KYC for privacy coin?   
This looks very much like some surveilance coin project with some government agencies behind it.

They announced they would launch their mainnet before the end of 2019, then 2020, then 2021. If you ask them if this is true, you will get kicked immediately. You can check with this question, but I don't recommend you to do this if you want to stay in the group.

Not spreading anything, but it looks that answer for everything from dero community and admins is FUD.
And yes, I was in correct telegram group.
