OneBit Core is programmed for advanced professional use to decide which block chain contains valid transactions. The users of OneBit Core only accept transactions for that block chain, making it the Bitcoin block chain that everyone else wants to use.
This shared agreement (called consensus) allows people like you to only accept valid bitcoins, enforcing Bitcoin's rules against even the most powerful miners. In addition to improving Bitcoin's decentralization, OneBit Core users get:
- Personal Remote Server created on your machine
- Better security for their bitcoins
- Privacy features not available in other wallets
- User interfaces and other powerful features

It is these users who keep Bitcoin decentralized. They individually run their own Multibit Core full nodes, and each of those full nodes separately follows the exact same rules to decide which block chain is valid.

There's no voting or other corruptible process involved: there's just individual software following identical rules—"math"—to evaluate identical blocks and coming to identical conclusions about which block chain is valid.

About Onebit core

OneBit Core checks each block of transactions it receives to ensure that everything in that block is fully valid—allowing it to trust the block without trusting the miner who created it.

This prevents miners from tricking OneBit Core users into accepting blocks that violate the 21 million bitcoin limit or which break other important rules.

Users of other wallets don’t get this level of security, so miners can trick them into accepting fabricated transactions or hijacked block chains

Why take that risk if you don’t have to? OneBit Core provides the best possible security against dishonest miners along with additional security against other easier attacks (see below for details).


OneBit Core ensures every block and transaction it accepts is valid, increasing not only your security but also helping prevent miners and banks from taking control of Bitcoin.
