How does ownership attribution on a public blockchain differ from that of a private blockchain

Public and Private Ledgers >>> How does ownership attribution on a public blockchain differ from that of a private blockchain >>> Introduction to Blockchain for Financial Services

 

 

The identity setup of a private or consortium blockchain is a design choice.

=================================

On a public blockchain, anyone can view the ledger, become a network node, and enter records on the ledger.

=================================

 

A private distributed ledger is permissioned, requires some degree of trust, and is not open to the public.

=================================

With a permissioned blockchain, a firm or consortium of firms controls who can view the ledger, who can become a network node, and who can enter records on the ledger.

=================================

 

On a public blockchain these identifiers (addresses) are pseudonymous. On a private blockchain, these identifiers may or may not be pseudonymous.

=================================

A zero-knowledge proof enables one party prove to another party that they know a value, x, without revealing x itself (or any additional information).

=================================

The R3 Consortium is an example of this.

=================================

An HD wallet algorithmically generates a new public/private key pair for every transaction, based on a single master seed key.

=================================

 

In a distributed ledger, control is distributed amongst the nodes in the network.

=================================

Blockchain has a high native level of transparency, which can help reduce information asymmetries.
