Understanding Transactions

Learn how to send, receive, and track transactions on BMC Chain.

Transaction Types

Type Description Gas Cost
BMC Transfer Send BMC tokens to another address 21,000 gas
Token Transfer Send BMC-20 tokens ~65,000 gas
Contract Interaction Execute smart contract functions Variable

Gas and Fees

BMC Chain uses a gas-based fee system similar to Ethereum:

  • Gas Price: Currently ~1 gwei for fast transactions
  • Gas Limit: Maximum gas you're willing to spend
  • Transaction Fee: Gas Used × Gas Price

Network > Consensus

Consensus Mechanism

BMC Chain uses Proof of Authority (PoA) consensus for fast, secure, and energy-efficient block production.

How PoA Works

Authority Nodes

Pre-approved validators with known identities produce blocks in rotation.

Fast Finality

Transactions are final once included in a block, no confirmation delays.

Energy Efficient

No mining required, dramatically reducing energy consumption.

High Security

Validators stake reputation, not just tokens, for network security.

Block Production

The consensus algorithm follows these principles:

  • Validators take turns producing blocks every 5 seconds
  • Round-robin rotation ensures fair distribution
  • Backup validators can step in if primary fails
  • Invalid blocks are rejected by network consensus
Network > Validators

Network Validators
