Season’s greetings all! Your hard-earned Zano can never be too well secured, so we're pleased to bring you news of the latest update to the Zano wallets (desktop and mobile) that adds an additional layer of protection for your funds.
Seed phrases began their history back in 2013 with BIP39, and have since become widespread. In simple terms, the seed phrase is a “humanized” form of recording a secret key, which is encoded not with hex characters or some other complex encoding, such as wallet addresses, but with a set of words commonly used in human language (English words for example). …
A digital signature is a “virtual bond” of almost any blockchain project. The vast majority of projects use practically the same signature as used on the Bitcoin network (namely ECDSA on the curve secp256k1). However, for projects in which the privacy of users plays a significant role, the creation of a digital signature often turns into a complex acrobatic act based on the latest achievements in discrete mathematics and cryptography.
The fact is that unlike ordinary blockchain projects, where the transaction clearly indicates which coin from which wallet is being spent, privacy blockchains use different methods to obfuscate the “trace”. One of the first to solve this problem was the CryptoNote project, which implemented a ring signature scheme. Such a scheme, instead of explicitly indicating the source transaction of the coins, allows for the inclusion in the signature of a group of randomly chosen transactions that are not related to this transfer. Thus an outside observer does not know from which transaction source the money is actually taken, it is only known that the sender proved his right to spend one of them. …
We’re very excited to announce the latest Zano release and to give you all a little information on what’s new.
Auditable Wallets and Foundation Fund Transparency
In response to requests from our community, we’ve dedicated ourselves to the task of making the Zano Foundation Fund completely transparent. Obviously achieving this in a coin designed to be private by default isn’t an easy thing, and we spent several months working to find a solution.
Work began with sowle’s extensive investigation into the possible implementations, which he compared at length in his research paper. From these options, we chose what we believed to be the most elegant and fitting solution for our use-case and set to work integrating it. The low-level functions were included in the last release and our new release builds upon them to allow the importing of auditible wallets via the GUI in both the desktop and mobile wallets. …
Unlike traditional bitcoin-like blockchains, (where anyone can watch balances and track the movement of coins in any wallet) privacy blockchains are very difficult or even entirely impossible to view without special access keys. Nevertheless, there are cases in which someone needs to be able to disclose the balance and movement of funds to interested third parties, while not allowing access to spend their funds. Such functionality for Zano will be presented today.
We’re happy to announce that as of version 188.8.131.52 Zano will feature auditable wallets.
Balance and transaction history of an auditable wallet can be tracked by a third party — an auditor — if and only if they receive a special key (called a “tracking seed”) from the wallet’s owner. The tracking seed may be published so everyone can watch the transaction history and balance (e.g. this could be useful in the case of a foundation), or shared with only a limited number of users. Its important to note that the tracking seed has the same level of security as a typical wallet seed phrase thus it is impossible for anyone to derive a tracking seed by knowing only the basic address. …
As you may have noticed the Zano team hasn’t had much news lately, but today we are excited to share three very important announcements!
New release with Auditable Wallets
First of all, we are excited to finally announce the release of the very important update, which implements the ability to create auditable wallets.
To put in simple terms, you are now able to create a special type of wallet — auditable wallet — and share a special tracking seed from it, which enables anyone that you share this tracking seed with to create a tracking wallet , this is a wallet that monitors the movement of funds and the balance of the original wallet, but does not allow access to funds. …
Following an extensive few months of research by Valeriy Pisarkov aka Sowle (Zano Core Developer), we are excited to release our findings on auditability in Cryptonote, with planned implementation to Zano. This blog post is just a short introduction to the research paper as it is over 30 pages in length. There are many different aspects of this research, for simplicity listed here are the main topics of the research:
Below we have a link to the PDF file of the complete research, we hope you are as excited about this as much as we are and we welcome any feedback on it.
Yesterday we released a new software build v184.108.40.206, in this version the most notable changes are some graphical changes and pre-downloading of the blockchain. The pre-downloading feature greatly reduces the sync time for fresh installs as it downloads a compiled image of the blockchain vs syncing block by block.
Listed below are all of the changes made since the last build release
[+] the first checkpoints are introduced for mainnet and testnet. Now space-saving technology is activated to keep both blockchain storage volume and sync bandwidth smaller. Checkpoints-related code was reviewed and polished before that.
[+] blockchain pre-downloading was implemented in order to significantly reduce sync-from-scratch time. …
As many know it was some time since the road map has been updated, you may have already seen we updated it several days ago shifting some goals around and moving some more urgent items up in the time frame. Today I will go over some of the changes and additions and explain the reasoning behind it. In the last Dev update it was mentioned that the privacy upgrade was the next major upgrade on the list, around the first of the year we decided to delay this to begin development on the mobile wallet.
The biggest change was moving up completion of the mobile wallet, while the privacy upgrade was and is the #1 focus of our research team, some of the development shifted to expedite the mobile app as is became clear this was important to our users. This release is planned for the coming months along with marketplace templates which will allow users to easily build their own E-commerce store on the Zano blockchain. …
Its been quite some time with any updates so today we have just a short post on the recent listing on TradeOgre
TradeOgre has built a reputation of being one of the more functional and reliable exchanges for miners over the past several years, with over 70 different projects listed that put emphasis on privacy. We want to thank the entire Zano community for stepping up and submitting the listing requests over the last week, as this is likely the reason we got listed there so once again thank you all for your efforts.
Hi Everyone, it’s been a while since our last update but today we want to give you a more in depth overview of developments that have been accomplished over the past few months.
With the hard fork to upgrade the POS consensus on September 21st these are the major changes that happened at that time.
As stated at the time of the fork the main objective was to secure Zano TX history to make 51% attacks practically impossible.
• Changed POS rule that previously would not allow locked coins to participate in POS mining as a result time-locked coins now immediately participate in POS mining. …
