Mainnet live since October 1, 2026

Since 2018

Changing the way cryptocurrency is exchanged around the world.

XcelR has been a public project since 2018. The 2026 mainnet is a fresh start from genesis block 0: coins from the 2018 and 2021 XcelR networks do not carry over, and the new chain has no premine, no sale, and no dev fee. The network is days old and its privacy is still weak. Read why before you use 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 running on its own independent network, with its own ports, address prefixes, network ID, and seed node. Its consensus rules, emission curve, and hard-fork schedule are fixed in the release you run, and an XcelR node only ever talks to other XcelR nodes.

The 2026 mainnet is a fresh start. It began from genesis block 0 on October 1, 2026, and every XCL on this chain was mined after that. Coins from the 2018 and 2021 XcelR networks do not carry over, and the new chain has no premine, no ICO or token sale, and no developer fee taken from block rewards. Read the history.

What exists today: the XcelR node, a command-line wallet, and a block explorer. A desktop wallet is in development and is not published yet.

It is small. There is one seed node and very little hash rate, so anyone who runs a node right now is a large part of the network.

Disclosure: the first six blocks (about 105 XCL) were mined by the launch node itself. A lone node has nobody to sync with, and the chain had to start somewhere.

Since 2018

XcelR has been a public project since 2018. Two earlier XcelR networks came before the chain that runs today. They are history: their rules and their coins are not part of it.

Project timeline. Choose a date to read what happened.

  1. The project starts

    The XcelR 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 are not part of the 2026 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 are not part of the 2026 chain.

  5. Current network

    A new mainnet, from block 0

    A new mainnet starts on a privacy-focused codebase, from block 0. Its privacy is still weak today; the privacy caveat explains why.

    See the live network console

The 2026 mainnet is a fresh start. Coins from the 2018 and 2021 XcelR networks do not carry over, and the new chain has no premine, no sale, and no dev fee.

Emission

Every block pays its miner a reward that shrinks slightly with each block, until it reaches a fixed floor. These curves are computed in your browser from the consensus rules in release 0.1.0.0. They show the schedule, not a forecast.

The model is checked against live block rewards when the network API answers.
The reward for a block is (264 − 1 − coins already issued) ÷ 220 atomic units, rounded down, while blocks are 60 seconds apart, and ÷ 219 once they are 120 seconds apart. It never falls below 0.3 XCL per minute of block time. One XCL is 1012 atomic units. The model assumes no block exceeds the penalty-free size. Transaction fees are not new coins and are not counted.

Privacy at launch: read this

Version 1 rules apply now

XcelR's privacy is weak today. Its hard forks are scheduled by block height, so the chain starts on its earliest rule set and only gets each later protection when it reaches that fork's height. At normal block times, that takes years.

  • Amounts are public

    RingCT transactions are rejected until v4, so every transaction shows the amounts it moves, in the block explorer and to anyone running a node.

  • There is no minimum ring size

    The network accepts transactions with no decoys, which point straight at the output being spent. Even when decoys are used, a young chain has very few outputs to pick them from.

  • Mining uses the original CryptoNight

    ASIC miners exist for that algorithm, and those machines can mine XcelR today. RandomX, the CPU-oriented algorithm, only starts at v12.

What works from day one: one-time (stealth) addresses. Your wallet address is never written to the chain, and payments to you can't be matched to it without your view key.

Treat XCL as a transparent coin for now. Don't use it for anything that needs privacy until the forks below are behind it.

    Ring size 16, Bulletproofs+, and view tags: the full modern privacy rule set.

Dates assume blocks arrive on target (60 seconds until v2, 120 seconds after). Real block times drift with hash rate, so treat them as rough. This is the schedule release 0.1.0.0 enforces; changing it would take a new release that node operators choose to run.

Get started

Builds are available for Linux x86_64, and a macOS build is being added; check the downloads page. Only the command-line node (xcelrd) and wallet (xcelr-wallet-cli) are released.

There is no public node. Your wallet needs your own xcelrd running on the same machine.

  1. Download and check it

    shell
    $ curl -LO https://xcelr.org/downloads/xcelr-0.1.0.0-linux-x86_64.tar.bz2
$ curl -LO https://xcelr.org/SHA256SUMS
$ sha256sum --check --ignore-missing SHA256SUMS
$ tar xjf xcelr-0.1.0.0-linux-x86_64.tar.bz2
$ cd xcelr-0.1.0.0-linux-x86_64

    The binaries are not signed. The checksum shows that your download matches what this server publishes; it doesn't prove 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 height and peers. To let other nodes connect to you, allow inbound TCP 28880. RPC stays on 127.0.0.1:28881, reachable only from your machine. For other options, use 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 it down offline; it is 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; pass --daemon-address 127.0.0.1:28881 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 the reward unlocks after 60 blocks. There are no pools, and P2Pool is not supported. If start_mining replies BUSY, your node hasn't synced with a peer yet; wait until status shows that it is synchronized. The mining estimator shows how long a block takes on average at the current difficulty.

Tools

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

// Mining estimator

Needs JavaScript

While you are mining, 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 –

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 change as miners join or leave. The network hash rate is an estimate: difficulty ÷ block target.
