One of the most common complaints from new Nerva users is how long it takes to sync the blockchain from scratch. We heard you. We’ve been working on a set of code optimizations (tracked internally as PR65) specifically targeting sync performance, and we now have real benchmark results to share.
On an AMD Ryzen 9 7950X, PR65 synced the entire Nerva blockchain — over 4.2 million blocks — in 19 hours and 49 minutes.
The baseline v0.2.0.0 release was measured at 23 hours 9 minutes to reach block 3.5 million; extrapolating at the observed rate, a full baseline sync would take approximately 32–33 hours. That puts the overall improvement at roughly 40% faster, or about 1.67x the throughput.
Where the gains are biggest
The improvement isn’t uniform — it grows as the blockchain gets more recent:
Chain section
Improvement
Blocks 0 – 1M (older chain)
~6% faster
Blocks 1M – 2M
~33% faster
Blocks 2M – 3M
~37% faster
Blocks 3M+ (most recent)
~40%+ faster
The part of the chain that used to take the longest is now the part that benefits the most.
What changed under the hood
The optimizations target two areas of the block verification pipeline that had become increasingly expensive as the chain grew past Hard Fork 12:
Redundant weight median recomputation. Block weight limits are calculated using a rolling median of recent block weights. The old code recomputed this median from scratch for blocks it didn’t need to — particularly during the initial block cache build and for blocks in the middle of large sync batches. These calculations now happen only when actually needed.
Smarter cache validation. When looking up historical block data, the old code re-validated cached entries using a full hash comparison even when a simple height check was sufficient. The new code skips the expensive hash lookup when the block height already confirms we have the right entry.
Neither change touches consensus rules — they are purely internal performance improvements with no effect on how blocks are validated or the chain itself.
These improvements will ship very soon, alongside wallet restore speed improvements and several other fixes, but this is only step 1. More significant sync speed improvements are coming in Hard Fork 13.
On May 1, 2018, a cryptocurrency called Nerva launched with an unusual promise: no ASICs, no GPUs, no venture capital. Just CPU mining without pools, privacy, and a community. Eight years later — against considerable odds — that project is still alive. That is worth talking about.
Where It Started
Nerva was created with a clear vision: a truly decentralized, CPU-only privacy coin built on Cryptonight Adaptive — an algorithm designed to stay resistant to specialized mining hardware and mining pools. No ASIC farms, no GPU rigs — just ordinary computers run by ordinary people.
The early years brought real momentum. The algorithm attracted attention, the CPU-only mining philosophy resonated with people who believed decentralization actually mattered, and a community began to form around something that felt different.
The Years Nobody Talks About
What happened next is the part of Nerva’s history that deserves the most respect. After the founder left in 2021, the project did not die. A small group of community members stepped in, stabilized the network, maintained the software, and kept building — NervaOne, NerVault, core updates — largely without recognition and certainly without guarantees.
It was not glamorous work. It was the kind of work that keeps something alive when it would be easier to walk away.
In January 2026, Nerva was listed on NonKyc exchange, bringing renewed visibility and fresh energy into the project. The current outstanding supply stands at 19.16 million XNV, and the network continues to tick along — one block per minute, as it always has.
What Just Shipped
The birthday comes with two significant releases.
Nerva Core Software v0.2.1.0 dropped on April 23, 2026. This point release brings new CLI options for DNS and block tracking, mining thread visibility in daemon status, wallet stability improvements, multi-architecture Docker images for broader platform support, and Android compatibility for running the daemon on mobile.
NervaOne Wallet and Miner v1.0.0 was released a few days ago. You can now run a full Nerva node or wallet directly from your phone. The interface was rebuilt from the ground up to work consistently across desktop and mobile. Setting up a public node connection is faster and simpler. The address book got meaningful improvements. Sensitive wallet data now has a shorter memory lifetime during operations. And for impatient users, you can download the blockchain database directly — no more waiting through a full sync from genesis.
Eight years in, Nerva now fits in your pocket.
What Comes Next Is Up to You
Nerva is an open-source, community-driven project. There is no company behind it. There is no funded team. There are no employees. What gets built is built by people who care enough to show up.
That is either a weakness or a strength depending entirely on what the community decides to do with it.
If you mine Nerva, you are mining a CPU-only privacy coin the way it was meant to be — solo, no pools, just your processor against the network. If you run a node, you are part of the network’s backbone. If you write code, document something, translate content, post on social media, answer a question from a new user, or simply tell someone that Nerva exists — you are contributing to whether this project becomes something.
No single person can make Nerva succeed. A few developers and a handful of dedicated contributors cannot do it alone either. The projects that survive at eight years and thrive at ten are the ones where the community treats it as theirs — because it is.
Get Involved
Mine XNV — any CPU can participate. See the mining guides at nerva.one.
Run a node — NervaOne v1.0.0 makes it easier than ever, including on Android.
Contribute code — the repositories are open. Pull requests are welcome.
Build something new — create something that uses XNV.
Spread the word — write about it, post about it, tell someone.
Join the conversation — find the community on Discord, Telegram and socials.
Eight years is a long time for a small project to survive. Whether the next eight years are remarkable is not predetermined. It depends on the people who decide to be part of it.
Whether Nerva becomes something — that is up to you.
There are so many scammers in crypto. You have to be very careful out there. Here is Poppy Anderson supposedly from KuCoin, @Poppy_Kucoin1. The day of this conversation, this user ID validated on https://www.kucoin.com/cert. The next day, it was no longer validating.
He probably did not expect me to be able to submit the application and wanted me to come back to him for help, at which point he would probably offer “other solution”. Well, half a day after my last message, he deleted this conversation from Telegram which 100% confirms to me that this was scam attempt.
Wen Nerva on KuCoin? 😁

Hello team,
Anderson from the KuCoin Listings Team (verified on the KuCoin website).
Our team has recently evaluated your project for possible KuCoin listing consideration For selected projects, listings can proceed without listing fees, with liquidity required for our market maker
KuCoin continues to rank among the top exchanges on CoinMarketCap,
So I believe you’re already familiar with our platform.
21:32
Rob Coder
Yes, I’ve used KuCoin a while back.
❤
21:32
Poppy Anderson || KuCoin
We are proposing a listing without any listing fees. We only ask for liquidity to support our market maker for 1 month.
KuCoin will use this liquidity during the period to provide smooth trading.
After the 1 month is completed, the full liquidity will be returned, and your token will remain listed on our spot market permanently.
21:33
So which pair u prefer for listing with Nerva?
21:33
Rob Coder
What are the liquidity requirements?
21:34
Poppy Anderson || KuCoin
We just intial liquidity to create trading pair and once token get listed u can add more liquidity
So initial required LP for USDT pair would be
5k to 10k Usdt + Equivalant in tokens
21:34
We will manage the liquidity first 30 days then we send back LP funds to original wallet and u can start ur own MM
21:34
We will do massive marketing before listing date
21:35
Rob Coder
Yeah, raising $10k – $20k might be a problem. The community is still small.
21:36
Poppy Anderson || KuCoin
How much can be done from ur side for the start
21:36
We just need to create trading pair first
21:37
Rob Coder
Why can’t trading pair be created with $500 + $500 in XNV? Why does it need to be this high?
21:38
Poppy Anderson || KuCoin
For smooth start so we can raise price organically but since its community driven and volume still small we can accept small amount just to create the trading pair
21:39
Plz confirm
21:39
Rob Coder
If it’s $500 USDT + $500 XNV, that would work.
21:40
Poppy Anderson || KuCoin
And once token get more volume after listing u can add more liquidity
We will do marketing for free
21:41
So announcement will be done within 2 hours after application done
Listing will be done within 5 days after announcement
21:41
Rob Coder
How can I confirm that this is legit offer through official KuCoin website?
21:42
Poppy Anderson || KuCoin
Sure u can verify me at kucoin verification page at our official website
Tell me once checked to proceed with steps of application
21:45
Rob Coder
I verified already but this sounds too good to be true so I’d like additional verification through official website or official X account .
21:45
Poppy Anderson || KuCoin
Just to clarify – we never use Twitter or emails for verification.
Those are only for announcements and updates.
That’s why kucoin has its official Verification Page, where you can check any real admin username directly. It’s the only secure and trusted method to confirm real kucoin representatives and avoid any impersonation.
21:45
We can send u an email from our official domain as second Verifcation
21:46
Rob Coder
Is the application submitted through the website?
21:47
Poppy Anderson || KuCoin
Yes for sure
21:47
Rob Coder
OK, so where do I go to submit the listing application?
2 We’ll send the signed agreement for your confirmation.
Transfer the required LP amount as stated in the agreement.
4 KuCoin will announce the listing and start the marketing campaign.
21:48
I will follow step by step until application done
21:48
Hope steps are clear please read and confirm
21:51
Rob Coder
Yes, steps are clear. As long as application goes through the website and I’ll get confirmation from kucoin.com email that I can reply to, I think that’s good enough.
21:52
Poppy Anderson || KuCoin
Sure
21:55
Rob Coder
OK, I will fill out the application tomorrow. Do I need to put anything specific in there or just fill out what it’s asking for?
21:55
Poppy Anderson || KuCoin
Just fill what its asking
If u have any question about the form let me know to help thanks
We’ve been working toward this for a long time, and today we’re proud to announce the official release of NervaOne Wallet and Miner v1.0.0 — our most significant update to date.
The headline? NervaOne is now on Android.
Android Support — Full Node in Your Pocket
Starting with v1.0.0, NervaOne runs natively on Android. Whether you want to run a full node or use it as a wallet only, the choice is yours — right from your phone. This has been one of the most requested features from our community, and we’re thrilled to finally deliver it.
A Redesign Built for Every Screen
To support Android properly, we went back and redesigned the majority of NervaOne’s views from the ground up. The result is an interface that feels at home on both desktop and mobile — clean, functional, and consistent across devices.
Easy Public Node Setup
Connecting to the network is now simpler than ever. The new Public Node setup flow gets you connected quickly with minimal configuration — ideal for users who want the NervaOne experience without running a full node.
Improved Address Book Integration
The Address Book has received meaningful improvements in this release, making it easier to manage your contacts and streamline transactions.
Better Memory Security for Wallet Operations
We’ve reduced the lifetime of sensitive data in memory during wallet operations, tightening up security where it matters most.
Faster Sync with Blockchain Database Download
For those who cannot wait to synchronize their blockchain database, there is now new download blockchain database option that lets you skip the long initial sync by downloading the chain directly – saving you significant time when setting up.
What Else Changed?
The application has been officially renamed to NervaOne, with the app folder updated to match. A clean name for a clean new chapter.
You can download latest version from GitHub or website:
Now that NervaOne also works on Android, it made sense to rename the application and make some folder structure changes.
If you are running NervaOne v0.8.5.0 or any of the builds prior to v1.0.0, you might want to copy some files over to the new directory structure.
First, make sure you have seed phrases and private keys saved securely for all you wallets!
If you run NervaOne v1.0.0, it will create new application folder called NervaOne and put all files under that directory. If you didn’t have any wallet files, you can just go to Daemon Setup and set up Mining Address or any other settings manually.
Migrate Application Settings
If you want to migrate your setting, go to Settings > Open Logs Folder
From there, go up 2 directories and you will see new NervaOne folder as well as old one called NervaOneDesktop. Go into NervaOneDesktop, copy app.config file and paste it into NervaOne directory.
Migrate Address Book
If you had address book, go to Wallet Setup > Open Wallets Folder
Find the same folder under NervaOneDesktop and you will find address.book file there. Under new NervaOne folder structure, this file has been moved and it needs to go under NervaOne > coins > xnv (or another coin such as xmr)
Migrate Wallets
If you want to move wallets, go to Wallet Setup > Open Wallets Folder
Find the same folder under NervaOneDesktop and copy all your wallet files to the new folder.
Migrate Client Tools
If you’re running custom build of CLI tools, go to Daemon Setup > Open Client Tools Folder
Find the same folder under NervaOneDesktop and copy the files from there to the new folder.
