HAVAH CHAIN

The HAVAH Chain is a proprietary blockchain of the HAVAH platform, designed to support secure interoperability with numerous existing blockchain networks. To ensure its safety and security, it has adopted Loopchain, which supports a proven interchain technology used on the ICON network for years known as BTP (Blockchain Transmission Protocol, reference link).

Technical Specifications

Key technical specifications of the HAVAH Chain are as follows.

Consensus Algorithm	LFT* (Loopchain Fault Tolerance)
Smart Contract	JVM (JAVA Smart Contract)
Max. TPS	3,000 TPS (Transactions Per Second)
Finality	Instant finality (2 Sec)
Interchain Technology	Supports BTP, applies relay-based interchain technology to heterogeneous blockchains.

LFT*: A consensus algorithm based on Practical Byzantine Fault Tolerance (PBFT), designed to improve the performance and security of the blockchain.

relay*: Unlike the notary method, where a predetermined intermediary sends an interchain transaction that occurred on the source chain to the target chain, the relay method does not require an intermediary and can directly verify that an interchain transaction has been agreed upon on the source chain from the target chain.

Network

The HAVAH Chain operates Mainnet and Vega for supporting DApp development, as well as Altair for supporting BTP development. The relevant information is as follows.

	Mainnet	Vega (testnet)
JSON-RPC API endpoint	https://ctz.havah.io/api/v3	https://ctz.vega.havah.io/api/v3
Block Explorer (HAVAH Scan)	https://scan.havah.io	https://scan.vega.havah.io
NID (network id)	0x100	0x101
