Bitcoin- Ledger vs Blockchain

The Bitcoin blockchain isn't the ledger. It's the foundation for a global, triple-entry accounting system with massive scale.

The historical evolution of ledgers and record-keeping

Ledgers have evolved from ancient tally sticks to the double-entry system, with each advancement fundamentally changing society and commerce.

How Bitcoin blocks create an ordered public ledger

The Bitcoin ledger is composed of validated transactions, which are ordered and secured within a chain of blocks using hashes and proof of work.

#3about 3 minutes

Understanding the security model of proof of work

Altering a past transaction requires redoing the proof of work for that block and all subsequent blocks, making attacks economically costly and easily detectable.

How Merkle trees enable efficient data pruning

Nodes can discard old transaction data by using Merkle trees, which summarize all transactions into a single root hash in the block header.

#5about 4 minutes

Bitcoin as the first global triple-entry ledger

Bitcoin enhances the double-entry system by adding a third entry: a permanent, objective, and globally interoperable transaction record on the blockchain.

#6about 1 minute

The responsibility for storing transaction data

Users or specialized data archiving services are responsible for storing their own transaction data, creating a market for data curation and management.

How Simplified Payment Verification (SPV) works

SPV enables users to verify the validity of their transactions by using only block headers, which is crucial for scaling the user experience.

#8about 4 minutes

The ledger as a distributed and specialized ecosystem

The global ledger exists as a distributed collection of data stored by specialized users and services, where any transaction can be validated against the chain of block headers.

Building a permanent and cooperative digital economy

The Bitcoin SV ledger provides a permanent, transparent, and secure data layer that reduces business costs and fosters global cooperation through shared information.
