SHA-256 ASICs
SHA-256d
Double SHA-256, Bitcoin's algorithm. Brings large, battle-tested hash power.
Mining
Your hardware. Your BITS.
Five algorithms run side by side on one chain, so CPUs, GPUs, FPGAs and ASICs can all earn BITS, and no single type of hardware gets to run the show.

01 · Algorithms
Five algorithms. One chain.
From block 501, five algorithms are live at the same time. Each block records which one mined it in its nVersion field.
Scrypt ASICs · CPUs
Scrypt
Memory-hard. The algorithm Bits-Crypto launched with, and the one URPool supports today.
GPUs
Skein
Skein-512 followed by SHA-256.
GPUs
Qubit
A chain of five hashes: Luffa, CubeHash, SHAvite-3, SIMD and ECHO.
FPGAs · GPUs
Odocrypt
Changes its internal structure every 10 days, seeded from the block timestamp, so fixed-function ASICs can't keep up.
Groestl (ID 2) is never active. Nodes reject any block mined with an inactive algorithm with the error bad-algo, so the rule is enforced by the whole network, not just by well-behaved miners.
Why five is safer than one
To rewrite history on a single-algorithm chain, an attacker needs a majority of one type of hardware. Here they would have to dominate four different hardware markets at once: SHA-256 ASICs, Scrypt ASICs, GPUs and FPGAs.
No algorithm picks the winner
From height 500, nodes choose the heaviest chain with a multi-algorithm work formula. Piling hash power onto one algorithm isn't enough to decide which chain wins.
02 · How it launched
Started on a CPU.
The chain launched with no industrial hardware required, then opened up to every kind of miner at block 501.
Heights 1 – 500
Launch phase: Scrypt only
- Scrypt with
N=1024, r=1, p=1, the same parameters as Litecoin. - Proof-of-work limit
~uint256(0) >> 20with no starting-target overrides, so every algorithm began at minimum difficulty. - Fully CPU-mineable.
~3,100 H/sone server CPU
~5.5 minper block found
Height 501 onward
Multi-algorithm phase
- Five algorithms live: SHA-256d, Scrypt, Skein, Qubit and Odocrypt.
- Each algorithm gets its own difficulty, adjusted every block.
- The heaviest chain is chosen with a multi-algorithm work formula.
03 · Difficulty: DigiSpeed V4
Adjusts every block. Per algorithm.
Hash power swings fast on a young network. Retargeting every block, separately for each algorithm, stops a big miner from grabbing cheap blocks and leaving everyone else stuck.
The target

5algorithms
=
75 sper algorithm
Each algorithm aims for one block every 75 seconds, averaged over its last 10 blocks, so the averaging window is 750 seconds. Together, the five produce a block every 15 seconds.
+8%max step harder per block
−16%max step easier per block
4%extra per-block correction toward each algorithm's fair share
It gets harder slowly and easier quickly, so the chain keeps moving if a large miner leaves.
04 · Start mining
Two ways in.
Join a pool for steady payouts, or run your own node and mine solo. The protocol is open either way.
Easiest
Mine with URPool
Point any Scrypt miner at our mining partner's stratum server and start earning shares straight away.

Full control
Mine solo
Run your own bits-cryptod node and mine against it directly. Pick any of the five algorithms and keep 100% of every block you find.
Get work for your algorithm

Mine blocks to an address (testing)

- Every 10 daysOdocrypt reshapes itself (every 864,000 seconds).
Mining partner
Powered by URPool.
URPool supports Bits-Crypto with a public mining pool, so anyone can start mining in minutes without running their own node.
- Stratum pool built on NOMP (Node Open Mining Portal).
- Live hash rate and block stats.
- Variable share difficulty, so small and large miners both submit shares at a steady pace.
- Scrypt today, with more algorithms to follow.
You don't have to use URPool. Anyone can solo mine against their own node or run a competing pool.
