Public Blockchains vs Private Blockchain

Developers should learn public blockchains to build decentralized applications, create cryptocurrencies or tokens, and implement transparent, tamper-proof systems for finance, supply chain, or voting meets developers should learn private blockchains when building enterprise solutions that require data privacy, regulatory compliance, and high transaction throughput without the openness of public networks. Here's our take.

Public Blockchains

Nice Pick

• Related to: bitcoin, ethereum

Cons

• Specific tradeoffs depend on your use case

Private Blockchain

Developers should learn private blockchains when building enterprise solutions that require data privacy, regulatory compliance, and high transaction throughput without the openness of public networks

Pros

• Use cases include secure record-keeping in healthcare, transparent supply chain tracking, and inter-bank settlements, as they allow for customization and reduced energy consumption compared to proof-of-work systems
• Related to: hyperledger-fabric, ethereum-private-networks

Cons

• Specific tradeoffs depend on your use case
