01 / THE PURPOSE
What is Hedera for?
Hedera provides token, consensus-message and smart-contract services. Users can submit transactions publicly, while participation in the current mainnet consensus-node set is permissioned.
02 / THE ARCHITECTURE
Three questions about the machinery.
How does it agree?
Consensus & securityHashgraph organizes gossip events in a directed acyclic graph and derives agreement through virtual voting. Its fault-tolerance guarantees depend on the protocol’s participant and network assumptions.
Where do instructions run?
Execution modelNative services provide common operations without requiring every application to recreate them in a contract. EVM-compatible smart contracts offer another execution path.
What is the token for?
HBAR in the systemHBAR pays network fees and participates in the staking system. Fees are denominated in US dollars but paid in HBAR; that pricing convention does not make HBAR a stablecoin.
03 / THE DESIGN CHOICES
What comes with the design?
Each architecture makes choices about security, performance, coordination, and who can participate.
Public transaction access should not be confused with permissionless consensus-node membership.
Council governance, service throttles and application admin rights are distinct control points.
04 / IN PRACTICE
Follow one use.
Illustrative: an application timestamps a business event through the consensus service. The ledger can attest to ordering without independently establishing that the reported real-world event was true.
