Mainnet restarted

Since 2018

Changing the way cryptocurrency is exchanged around the world.

XcelR has been around since 2018. In October 2026 its network started over from a new genesis block, this time with hidden amounts and ring signatures from block 1. There's no premine, no coin sale, and no dev fee. It's new and small, so see what the privacy covers before you count on it.

What XcelR is

The mission, since 2018 Our aim is to help businesses, companies, and everyday people buy and use cryptocurrency more fluidly and efficiently, with little to no friction.

XcelR is a cryptocurrency with its own peer-to-peer network. The project goes back to 2018. The chain you can use today started from a new genesis block in October 2026.

Nothing from before carries over. That covers the 2018 and 2021 networks, and also a chain that ran for seven blocks from October 1, 2026, on early rules with public amounts. It was replaced before any public use. Here's the whole history.

Today you can run the XcelR node, use the command-line wallet, mine solo, and look things up in the block explorer. A desktop wallet is in the works; once there's a build for your system, it will be on the downloads page.

It's small. There's one seed node and very little hash rate, so if you run a node now, you're a real part of the network.

Disclosure: the project mines too. A developer's computer mines from block 1 so that blocks keep coming. The downloads go up only after block 60, so nobody can game the chain's first difficulty adjustments, which means blocks 1 to 60 (about 2,111 XCL) all go to the project. Anyone can mine solo through their own node, and the more independent miners there are, the better.

Since 2018

XcelR went public in 2018. Three networks came before the one running today, and none of their coins exist on it.

Project timeline. Choose a date to read what happened.

  1. The project starts

    Work begins on a trading platform and the first XcelR coin.

  2. Announced on BitcoinTalk

    XcelR is announced on the BitcoinTalk forum.

    Read the announcement thread on bitcointalk.org (opens in a new tab)

  3. Earlier network

    The first XcelR network goes live

    A proof-of-work coin with a 50 XCL block reward. 1,008,000 XCL were premined and offered in a coin sale.

    History only. This network's rules and coins aren't part of today's chain.

  4. Earlier network

    Relaunched with a new genesis block

    Updated code and a new genesis block (XcelR Core 0.17.2): a Scrypt coin with 2.5-minute blocks, a 50 XCL reward that halves every 840,000 blocks, and an 84,000,000 XCL cap.

    History only. This network's rules and coins aren't part of today's chain.

  5. Replaced

    A first 2026 mainnet, on early rules

    A new mainnet starts on a privacy codebase but runs its earliest rules (version 1): CryptoNight mining and public amounts. It runs for seven blocks and is replaced before any public use.

    Nothing on that chain carries over.

  6. Current network

    Started over on modern rules

    The network starts again from a new genesis block. From block 1 on, every block follows version 16 rules, so amounts are hidden from the start. Read what the privacy covers.

    See the live network console

Today's chain is a fresh start. Coins from the 2018 and 2021 XcelR networks, and from the seven-block chain of October 1, 2026, don't carry over. It has no premine, no coin sale, and no dev fee.

Specs

All of this is fixed in release 0.2.0.0. Changing any of it would take a new release that node operators choose to run.

Launch
, from a new genesis block Genesis hash 5e196c370d4555eef1968182c913ae45dd6271a62db4c07730e682884aaaa32c
Ticker
XCL, 12 decimal places
Release
0.2.0.0 "Genesis", under the BSD 3-Clause license The 2026 source code isn't published yet.
Rules
Version 16, from block 1 The genesis block is created under version 1 rules, as on every chain of this design. No other block uses them.
Proof of work
RandomX Designed to run well on ordinary CPUs.
Block time
A 2-minute target Difficulty is recalculated for every block to keep the average close to it.
Mined coins unlock
After 60 blocks About two hours.
Amounts
Hidden, with RingCT and Bulletproofs+ range proofs The fee is public, and so are block rewards.
Ring signatures
CLSAG, 16 members The output being spent hides among 15 others.
Addresses
Prefix 973; standard addresses start with bJ Integrated 974, subaddress 975. Payments go to one-time addresses with view tags.
Ports
P2P 28880, RPC 28881, ZMQ 28882 RPC and ZMQ listen on 127.0.0.1 only by default.
Block reward
35.184338534400 XCL for block 1, then a little less with every block No halvings. Each reward is (264 − 1 − coins already generated) >> 19 atomic units, and 1 XCL is 1012 atomic units.
Main emission
About 18.13 million XCL, done at block 2,134,600 About 8.1 years at 2-minute blocks.
Tail emission
0.6 XCL per block after that, permanently So there's no hard cap.
Genesis output
17.592186044415 XCL, to a key nobody can spend A "nothing up my sleeve" key: it's derived from a public label, so nobody can know its private key.
Premine, coin sale, dev fee
None Apart from the genesis output, every XCL comes from mining.
Seed node
seeds.xcelr.org:28880, built into the binaries It's the only one for now.
Mining
Solo, through your own node No pools; P2Pool isn't supported.

Emission

Each block pays its miner a little less than the one before, until the reward reaches a floor of 0.6 XCL and stays there. Your browser works out these charts from the rules in release 0.2.0.0. They show the schedule, not a forecast.

When the network API answers, this page checks the model against real block rewards.
The reward for a block is (264 − 1 − coins already generated) ÷ 219 atomic units, rounded down, and never less than 0.6 XCL. One XCL is 1012 atomic units. The genesis block is the exception: it follows version 1 rules, which divide by 220, so its output is 17.592186044415 XCL, paid to a key nobody can spend. The model assumes no block exceeds the penalty-free size. Transaction fees aren't new coins, so the model leaves them out.

What XcelR hides, and what it doesn't

From block 1, every transaction follows the same privacy rules. Here's what they hide, and where a chain this young still falls short.

Hidden on the chain

Amounts
Every transfer hides its amounts with RingCT, and a Bulletproofs+ range proof shows each one is valid without revealing it. Only the fee is public. Block rewards are public too, which is how anyone can check the emission.
Which coin you spent
Each input carries a CLSAG ring signature over 16 outputs: the one you're spending and 15 others from the chain. Anyone can verify the signature, but not tell which of the 16 was spent.
Your address
Every payment goes to a one-time address, so your wallet address never appears on the chain. Finding the payments that are yours takes your view key. View tags let a wallet skip most outputs that aren't its own, which makes scanning faster.

Weak spots today

Few decoys
Your wallet picks the 15 decoys from outputs already on the chain. A young chain has few, and most of them are mining rewards, so early rings give less cover than later ones will. Anyone who owns outputs in your ring knows those aren't the one being spent, and at launch that includes the project, which mines from block 1.
Your IP address
The coin doesn't hide it. The nodes you connect to can see it, and so can the seed node when your node first joins. If that matters to you, connect through a VPN or Tor.
One seed node
New nodes find the network through seeds.xcelr.org, which the project runs. If it's down, a new node can't join until you give it a peer with --add-peer.
No outside review
The 2026 source code isn't published yet, and nobody outside the project has audited it.

Put together: the chain doesn't show your balance or your address, and following coins is harder than on a transparent coin. That isn't the same as being anonymous. If being identified could hurt you, don't rely on XcelR yet.

Get started

These steps use the Linux x86_64 build of the command-line node (xcelrd) and wallet (xcelr-wallet-cli). For other systems, check the downloads page.

There's no public node. Your wallet talks to your own xcelrd, running on the same machine.

  1. Download and check it

    shell
    $ curl -LO https://xcelr.org/downloads/xcelr-0.2.0.0-linux-x86_64.tar.bz2
$ curl -LO https://xcelr.org/downloads/SHA256SUMS
$ sha256sum --check --ignore-missing SHA256SUMS
$ tar xjf xcelr-0.2.0.0-linux-x86_64.tar.bz2
$ cd xcelr-0.2.0.0-linux-x86_64

    The binaries and the checksum file aren't signed yet. A matching checksum shows your download is the file this server publishes; it can't show who built it. The downloads page can also check a file in your browser.

  2. Run the node

    shell
    $ ./xcelrd

    On first run it creates ~/.xcelr and connects to seeds.xcelr.org on port 28880. Leave it running in its own terminal, and type status to see the height and your peers. To let other nodes connect to you, allow inbound TCP 28880. RPC stays on 127.0.0.1:28881, so only your machine can reach it. For more options, try the node command builder.

  3. Create a wallet

    second terminal, same folder
    $ ./xcelr-wallet-cli --generate-new-wallet mywallet

    It asks for a password and a seed language, then shows a 25-word seed phrase. Write that down somewhere offline: it's the only way to restore the wallet. Type address to print your address (it starts with bJ). The wallet connects to 127.0.0.1:28881 by default; add --daemon-address 127.0.0.1:28881 if you want to be explicit.

  4. Mine

    xcelrd console
    # typed into the running xcelrd terminal
> start_mining YOUR_ADDRESS 2
> stop_mining

# or start the node already mining
$ ./xcelrd --start-mining YOUR_ADDRESS --mining-threads 2

    The 2 is the number of CPU threads. Mining is solo: a block you find pays its reward to your address, and that reward unlocks after 60 blocks, about two hours. There are no pools. If start_mining replies BUSY, your node hasn't synced with a peer yet; wait until status says it's synchronized. The mining estimator shows how long a block takes on average at the current difficulty.

Tools

A mining estimator and a node command builder. Nothing you type here leaves your browser.

// Mining estimator

Needs JavaScript

While you mine, type mining_status in the xcelrd console to see your hash rate.

Average time to find a block – Network difficulty ÷ your hash rate.
Your share of the network –
YouEstimated network
Your hash rate ÷ (estimated network hash rate + yours).
Chance of finding at least one block, if your hash rate and the difficulty stay the same
WithinTimeChance
The average time–63%
Twice the average–86%
Three times the average–95%

These are averages, not a schedule. Finding a block is random, so a real wait can be much shorter or much longer. Difficulty is recalculated for every block, so the numbers move as miners join or leave. The network hash rate is an estimate: difficulty ÷ block target.
