The tech behind Bits-Crypto.

How the blockchain, the mining, the supply and the network really work. Every number on this page comes from the Bits-Crypto source code and the live network, not from marketing copy.

01 · What it is

Three layers of proven engineering.

Bits-Crypto (ticker BITS) is an independent Proof of Work blockchain with its own genesis block, rules and nodes. It shares no coins, history or peers with any other chain.

Layer 1

Bitcoin Core v26

The security model: UTXO accounting, script validation and peer-to-peer networking from one of the most reviewed codebases in the industry.

Layer 2

DigiByte Core v8.26

Speed and fairness: 15-second blocks, five mining algorithms and difficulty that adjusts per algorithm.

Layer 3

Bits-Crypto

Our own parameters: a new genesis block, supply schedule, address format and network.

100% open source. Anyone can mine it, run a node or read every line of code.

02 · The genesis block

Where it all began.

Every blockchain starts with one block that has no parent. Ours was mined on 11 October 2026 at 00:00:00 UTC, with a message written into it forever:

“AI opens the machine economy; blockchain keeps it fair. Freedom and access for all.”

The genesis values are reproducible: a script in the source re-mines them, and every node refuses to start if the hash doesn't match the one hard-coded in its chain parameters.

03 · Speed

A new block every 15 seconds.

That's 40x faster than Bitcoin. Your payment gets its first confirmation in seconds and several confirmations in about a minute. Frequent blocks also spread rewards more evenly across miners.

04 · Coin supply

Fixed rules. Hard cap.

Block rewards are enforced by consensus in GetBlockSubsidy(). Every node rejects a block that pays itself more than the rules allow.

  • ~21.09B BITSMaximum supply. It can never be exceeded.
  • 1,000 BITSReward per block today, every 15 seconds.
  • Every 5 yearsThe reward halves (every 10,512,000 blocks).
  • 8 decimals1 BITS = 100,000,000 base units.

05 · Mining

Five algorithms. One chain.

Most coins pick one mining algorithm, which lets whoever owns the most specialised hardware dominate. Bits-Crypto runs five at once, so GPU owners, FPGA owners and ASIC farms can all earn BITS.

SHA-256 ASICs

SHA-256d

Bitcoin's algorithm. Brings large, battle-tested hash power.

Scrypt ASICs · CPUs

Scrypt

Memory-hard, and the algorithm Bits-Crypto launched with.

GPUs

Skein

Built from a finalist of the SHA-3 competition.

GPUs

Qubit

A chain of five different hash functions.

FPGAs · GPUs

Odocrypt

Reshapes itself every 10 days. A custom chip takes months to design, so ASICs can't keep up.

See the full mining guide How the chain launched, DigiSpeed difficulty, how to start mining and our mining partner URPool.

06 · Security & upgrades

Modern from day one.

Older chains switched on improvements one at a time over years. Bits-Crypto started with all of them active.

BIP34

Block height in every coinbase, so each one is unique.

BIP65 · CLTV

Time-locked coins.

BIP66

Strict signature encoding.

CSV

Relative time locks, the base for payment channels.

SegWit

No transaction malleability, cheaper transactions, bits1… addresses.

Taproot

Schnorr signatures for more private, efficient smart contracts.

Cryptography inherited from Bitcoin

  • libsecp256k1: the curve library that secures Bitcoin, with ECDSA and Schnorr signatures.
  • SHA-256 & RIPEMD-160 for transaction IDs, block hashes and addresses.
  • AES-256 encrypts your wallet on disk when you set a passphrase.
  • LevelDB, Minisketch & SQLite for fast storage, efficient peer sync and modern descriptor wallets.

Upgrades are decided together

Future changes use BIP9 signalling: an upgrade activates only when 70% of blocks in a one-week window (40,320 blocks) signal support. Miners and node operators decide together.

Replace-by-fee is off. Once a transaction is broadcast, it can't be swapped for another with a higher fee, so fast payments stay predictable.

07 · Privacy

Share less. Control more.

On most blockchains, the first node to broadcast a transaction is probably the sender, so anyone watching can link payments to IP addresses. Bits-Crypto relays transactions with Dandelion++, on by default.

  1. 1

    Stem

    Your transaction is passed privately from peer to peer along a random path, held in a separate “stempool”, not the public mempool.

  2. 2

    Fluff

    After a random number of hops, one node broadcasts it to everyone as usual.

  3. 3

    Embargo

    If it doesn't show up publicly in time, a node broadcasts it itself, so nothing gets lost.

To an observer, your transaction appears to come from a random node somewhere on the network, not from you.

08 · Network

No node trusts another.

Every node keeps a full copy of the chain and checks every block and transaction on its own. That's what “no one owns the switch” means in practice.

Unique network “magic bytes” start every message, so Bits-Crypto nodes ignore traffic from other chains and the networks can never accidentally merge.

Addresses you'll recognise

Addresses are unique to Bits-Crypto, so coins can't be sent to the wrong chain by mistake. HD wallets mean one backup restores every address.

Tiny fees, no spam

Min relay fee
0.001 BITS/kB
Fallback fee
0.01 BITS/kB
Min wallet fee
0.1 BITS/kB

A typical transaction is a few hundred bytes. As block rewards halve over the decades, fees take over as what keeps miners securing the chain.

The live network today

  • 5 full nodesall connected to each other and restarting automatically on failure
  • ~20 minto deploy a new node with a scripted setup
  • Tested twicethe multi-algo fork passed on a private test chain (14 / 14 checks) and on a full copy of mainnet before going live
  • ~90 sfor each live node to upgrade, well before block 500

  • Verifiable buildsReproducible genesis, published checksums and open-source code.
  • Test before deployEvery consensus change is proven on a test chain and on a copy of mainnet before it goes live.
  • Wallet-based identityAcross the ecosystem, a key you own replaces usernames, passwords and personal data.
