Bitcoin 1.01

Technical summary

01Signatures

Every transaction is signed with SLH-DSA-SHAKE-256s. Its security rests only on a hash function; Shor's algorithm, the method a quantum computer would use to break today's signatures, does not apply.

NIST FIPS 205 · 29,792-byte signature · passes every official test vector

02Hash

ORION: Keccak-f[1600], the core of SHA-3, with a 1024-bit capacity. ORION-512 output is identical to standard SHA3-512, so it can be checked with any SHA-3 tool.

block ID 1024 bits · transaction ID 512 bits

03Network

Nodes find each other on the local network, through seed computers, and from addresses they learn from one another. No domain, hosting or central server is needed. Every connection is encrypted with X25519 + ML-KEM-1024; private messages and signed posts are stored and forwarded by peers.

TCP 10102 · UDP 10101 discovery · IPv4 + IPv6 · protocol 4 (encrypted)

04Money

15-minute blocks, a 75-coin block reward, halving every 140,000 blocks (about four years). Every block needs at least 2^36 attempts; difficulty is adjusted every block with the relative ASERT rule.

05Swaps

Atomic swaps with Bitcoin over HTLCs: either both sides get paid, or both get their own money back. There is no exchange or custodian in between.

Bitcoin bridge · no intermediary

06Wallet

The wallet stays only on your own computer, encrypted with your password. A single backup restores every address.

07Bitcoin anchor

Now and then nodes write a block's digest to Bitcoin. An anchor with 6 confirmations on Bitcoin protects that block independently of the miners' hash power: a heavier branch mined in secret cannot undo it, and a branch that anchors itself early leaves a trace on Bitcoin that everyone can see. Half of the anchored block's reward goes to whoever anchored it.

08Science layer

A design that directs half of the mining reward to scientific computation whose results can be verified: drug-candidate screening, materials discovery.

A heartbeat in every block

Every block header records how many steps the number (height + 27) takes to reach 1 under the 3x+1 rule. It plays no part in security; it is the chain's signature. At genesis the number is 27: it reaches 1 in 111 steps, climbing as high as 9,232 on the way.

The mainnet launch date is not final yet; the genesis block will be mined at launch. The rules and the reasons for them are in the whitepaper. When the network opens, the program will be published on the Download page together with its verification hashes.
