List of prominent (Bitcoin) people that spoke positively about Monero
Since we probably got a lot of new eyes and subscribers here, I thought it would be good to post this list again and add some updates to it. Over Monero's existence a lot of prominent people have spoken positively about it and praised the tech behind it, either directly or indirectly. Directly:
Dr. Tomaso Aste – Head, Financial Computing & Analytics Group - Department of Computer Science - University College London ("Prof. Aste gave a talk on CN at some fancy confab")
Indirectly: Satoshi Nakamoto, founder of Bitcoin |  &  From the second link:
As an example, say some unpopular military attack has to be ordered, but nobody wants to go down in history as the one who ordered it. If 10 leaders have private keys, one of them could sign the order and you wouldn't know who did it.
This perfectly describes how ring signatures work. P.S. If someone else knows others, feel free to post it!
Wikipedia has "pillars", foundational commitments which guide its develoments. Similarly, Monero has three pillars. The three pillars of Monero are privacy, decentralization and scalability. Now what does it means?
Monero is true electronic cash. With Monero, you can know that a transaction occured, but not whence, how much and whither, whilst it is getting increasingly easy to trace Bitcoin (mixers, tumblers… do not work). See this illustration on how it positions compared to Bitcoin and this animation on how it works. Monero is a cryptocurrency that is based on the CryptoNote protocol and reference code, and that seeks to provide absolute transactional privacy (fluffypony). But Monero is more than a currency. Its official slogan is "secure, private, untraceable" for a reason. Other transactions than the monetary ones benefit from it. You may not want anyone to know you signed this contract. You may not want the forthcoming blockchain-powered internet of things cloud around you to be accessible by anyone, and this requires an opaque blockchain, that Monero provides. We hired academic cryptographers to review and improve the security of Monero and started an external audit as well. Even Bitcoin developers and independent cryptographers (Andrew Poelstra/andytoshi, Gregory Maxwell, Nicolas Courtois) speak high of Monero and Cryptonote. Finally, security is a chain as strong as its weakest link. What is privacy of the transaction worth if your IP is revealed? This is why we are teaming up with Privacy Solutions to have an i2p router implemented in Monero. IP obfuscation, amount obfuscation, recipient obfuscation, sender obfuscation. May I remind everyone that privacy is more than drugs and illegality? Are you ready to give everyone (EVERYONE) read access to your bank account? Would your like your ex-wife, your son, your boss, your neigbour or (particularly if you are a company) your competitor to know how much money you have, where it comes from and what you doing with it, forever (and no, multiples addresses or mixers or tumblers just don't work)? Would you like your landlord to know that you just got some money, so s/he can raise the rent? Privacy is also making it possible for journalists fighting for the freedom of press to do their jobs when there are in a dictatorial (or not-so-dictatorial) country. This is also about not being incriminated because your money was tainted (two transactions before, it went from drug dealing, for instance).Countless studies showed that people behave differently when they know they might be watched. As tacotime (a core team member) said back in April, when Monero was only one week old, Fuck the pump and dumps, we're here to create something with value that people can use.
Despite being decentralised at heart, cryptocurrencies are increasingly centralised. Webwallets, exchanges, pool mining and cloud mining, centralised seedings or masternodes… All of this is susceptible to attacks (both technical or legal - remember that "legal" doesn't necessarily means "legitimate"). Whilst Monero is decentralised mixing. By contrast, we are trying hard to keep Monero decentralised. Our domain names for the most parts are meant to be resistant to such attacks (gun.io on choosing domain names and registrars). The core team is composed of both public faces (myself and Riccardo Spagni/fluffypony) and private faces (the other core team members) located on various continents with widely different timezones, making sure that core devs are avaialble 24/7. This extends to technology too. When implementing something, we keep in mind how it will affect decentralisation. We recently released the first Monero torrent and we also created an open standard for simpler sending of cryptocurrencies, OpenAlias. The smart mining forthcoming feature will allow transparent CPU mining on your own computer, far from the de facto centralisation of mining farms and pool mining. We intend to pursue Satoshi's original vision of a true p2p currency. "Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized." (smooth).
Monero is meant to stay. Long. This means it must be able to be adopted by anyone, that anyone can use it. Open-source is a given and smart mining participates of it too. But beyond this, we chose a currency code a.ka. ticker symbol (XMR) that adheres to the international monetary standard ISO 4217. We are doing our best to follow technological best practices. Recently, we worked with Kitware to have our Cmake tool adhere to the best practices and we will soon transition to semantic versioning (semver.org). Similarly, the block time, mixin count… are designed (and sometimes redesigned) with long-term scalability in mind. More importantly maybe, Monero doesn't suffer from some of the inherent flaws of many orther cryptocurrencies. Monero is fair-launched and doesn't have a 1 MB blocksize which limits the ultimate amount of transaction per day. Today, it doesn't matter much, but tomorrow when Monero will be much more popular, this will be instrumental in ensuring that Monero can continue to grow - this is the whole point of scalability: it may not matter today, but it does for tomorrow when it will be so hard to change it. The same consideration are given to the emission curve. We believe (and we are not the only ones), that relying only on transaction fees won't be enough of an incentive for miners (remember: the core of the blockchain is to rely on an economic incentive, because it is not possible to solve the Byzantine Generals' problem with math alone). This is why Monero implements a "tail emission" that will kick off once the main emission is over, in less than eight years. Scalability is not only about technology. It also about making sure that everyone gets their side of the bargain or else it will be rejected. That's why Monero is also optionally transparent. This means that, on a completely voluntary basis, one can give read access to someone else. Quoting fluffypony on reddit: "A view key can be used to reveal all transactions for an account. This means that companies could still be audited, charities could make their accounts publicly visible, and parents could see what their kids are spending the money on. Additionally, details of a transaction can be revealed via a similar mechanism on a per-transaction basis." This is also to increase legitimacy that the Monero Economy Workgroup (disclaimer: I am an executive of the MEW) was created (what is MEW? - join MEW). The MEW takes decision (that, granted, the core team is not bound to accept, but refusing a widely adopted decision would cause turmoil) and since the MEW is meant to represent the will of most holders, it will increase legitimacy: something decided by the MEW is something most holders are willing to do. The debate on the emission curve is a perfect example: the MEW unanimously decided to not change the emission curve, and confidence went back immediately. Consistent confidence is part of scalability. Security, decentralization, scalability. These are the three pillars of Monero. The vision of Monero is to be as future-proof as possible.
Naviaddress is the first global digital addressing system that is being deployed onto the blockchain. It will provide people and businesses with freedom and ability to create, obtain, own, lend and sell their digital addresses. We call them naviaddresses - unified digital IDs for any place and object in real and virtual worlds. Naviaddress main aim is creating a decentralized and unified global address platform that could be used in both the real and virtual world. It is using a proprietary technology patent that is pending. It is developed on a platform that is capable of assigning a digital address to any location in the world, with just the simple use of geo-coordinate precision. Naviaddress provides a way for users of the platform to create their own digital addresses. These addresses consist of anywhere between 1 and 18 digits, this eliminates the problem of the language barrier. Naviaddresses are divided into three categories, namely custom, postal and global Naviaddresses. Custom Naviaddresses can only be created by platform users and represent dynamic objects. They can only refer to one place at any given moment, but can easily be moved to another location by its creator. A postal Naviaddress on the other hand cannot be created by a platform user. It is a pre built, unique, combination of digits that is comprised of existing postal address information and international telephone codes, as such it also cannot be easily moved and is used to represent static objects, like buildings or locations. Global Naviaddresses are given to the user upon registration on the platform. These are for mobile objects, like mobile phones, vehicles, or animals. FEATURES of "NAVIADDRESS ADDRESS" The major features which makes Naviaddress outstanding are
Ethereum Blockchain ID ownership management SW solution BigchainDB
Reliable and cheap metadata storage
Open sourced oriented SDK and API providing access to the platform
On Four Original Sins of Open Source Crypto Currencies and Some Possibly Catastrophic Events
There are four built-in properties of bitcoin which cryptographers such as Nicolas T. Courtois and Jean-Jacques Quisquater consider to be the original sins of bitcoin and which have also been copied by many other crypto currencies. I have access to an unpublished paper by them. In the paper, they advocate a more careful approach than massively using "untested" cryptographic solutions. They revisit several well-known cryptography and security engineering principles and show that they can provide definite solutions which could make digital currencies more robust. For example they show that even if there is no attack yet on the discrete logarithm problem in secp256k1 there are definitely things which can be done right now in order to protect bitcoins from being stolen in the future. They postulate that crypto currencies demand STRICTER security requirements than traditional financial systems (already very difficult). In traditional finance market/payment participants are trusted and the system designers/engineers are trusted. In open systems such as bitcoin there is no way to exclude malicious participants. They can run a large part of the network or even infect the source code or the broader business ecosystem with subversive functionalities such as allowing for-profit blockchain manipulation as a service. They examine a number of recent catastrophic events in various crypto currencies which have been programmed in advance in the source code and nobody had noticed before it was too late. Clearly the security of open source crypto currencies cannot be take for granted. They claim that they actually require new security paradigms to be developed. For example in this paper they show that security of current bitcoin against double spending attacks can be improved with a new notion of "plaintext aware hashing".
