It utilizes chain abstraction to remove the complexities of interacting with different [blockchains](https://iq.wiki/wiki/blockchain), intending to provide a unified experience across [Bitcoin](https://iq.wiki/wiki/bitcoin), [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) chains, heterogeneous [L2](https://iq.wiki/wiki/layer-2) solutions, and other protocols. This allows users to interact seamlessly without switching networks or dealing with complicated interfaces. The network's [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) compatibility is designed to enable developers to use existing tools and applications, facilitating the expansion of any [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) application to Hana Network.  \n  \nHana Network aims to develop user-friendly applications for those new to the [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) space. These applications, featuring permissionless onboarding, are intended to simplify experiences in social finance, gaming finance, payments, and real-world services.[\\[1\\]](#cite-id-je0j4ft5z38)[\\[2\\]](#cite-id-8y5mwwqg1z7)[\\[3\\]](#cite-id-dw5t8b3wa9e)[\\[7\\]](#cite-id-skqneup7jr)[\\[8\\]](#cite-id-lmjdridke9)[\\[9\\]](#cite-id-ryqdp7yo5zo)  \n![1*hBuUQYn2q2iW64pi38drVw.webp](https://ipfs.everipedia.org/ipfs/QmYvknS5TYBfa4a8nDztRv9mcsNGjHAB652kmKXXfXujmG)  \n  \n# Architecture  \n  \nHana Network operates as a [Proof of Stake (PoS)](https://iq.wiki/wiki/proof-of-stake) [blockchain](https://iq.wiki/wiki/blockchain) utilizing the [Cosmos](https://iq.wiki/wiki/cosmos) SDK and [Tendermint](https://iq.wiki/wiki/tendermint) consensus engine. It aims to facilitate connectivity with [Ethereum](https://iq.wiki/wiki/ethereum), [Bitcoin](https://iq.wiki/wiki/bitcoin), and other Layer 1/[Layer 2](https://iq.wiki/wiki/layer-2) networks through the incorporation of the Threshold Signature Scheme (TSS). Positioned as a consumer-focused omni-chain protocol, Hana Network integrates both on-chain and off-chain services to foster innovation and enhance user connectivity.  \n  \nThe decentralized gateway layer is designed to remove centralized intermediaries, promoting network trust and transparency. This architecture supports a variety of consumer applications, aiming to be adaptable and scalable within the [blockchain](https://iq.wiki/wiki/blockchain) ecosystem.[\\[2\\]](#cite-id-8y5mwwqg1z7)  \n![docs_image_1-240608.png](https://ipfs.everipedia.org/ipfs/Qme4pEUoeZNLErRSmPAo6t4nwZsirxBXMZqj4eJDnAoWJE)  \n  \n## Gateway Function  \n  \nThe Gateway Function within Hana Network aims to act as a secure bridge, facilitating seamless interactions with external chains and enterprise products by simplifying chain-specific operations across different [blockchains](https://iq.wiki/wiki/blockchain). Utilizing the Threshold Signature Scheme (TSS), it securely tokenizes assets such as [Bitcoin](https://iq.wiki/wiki/bitcoin) and [Ethereum](https://iq.wiki/wiki/ethereum) for integration within Hana Network.  \n  \nThe function implements decentralized key management to protect addresses, requiring multi-validator authorization for signatures, thereby enhancing overall security and trust. It supports various asset types on Hana Network, enabling integration with external services to foster [blockchain](https://iq.wiki/wiki/blockchain) connectivity and facilitate innovative applications.[\\[2\\]](#cite-id-8y5mwwqg1z7)  \n  \n## Node  \n  \nIn Hana Network, [nodes](https://iq.wiki/wiki/node) serve distinct roles alongside Network Validators responsible for block generation. These roles include TSS Signers, tasked with managing private key sharing for external chain assets and services, and Observers, responsible for monitoring transactions and consensus on external chains. [Nodes](https://iq.wiki/wiki/node) operate within specific epochs to facilitate block creation and ensure the functionality of the Hana Gateway within the network.[\\[2\\]](#cite-id-8y5mwwqg1z7)  \n![light_(7).png](https://ipfs.everipedia.org/ipfs/QmYbAswzpaLcDuvGxUuRFqYbiQCZbXGJe3x5ds9wKT1SJ6)  \n  \n### Node as Network Validator  \n  \nWithin Hana Network, Network Validators utilize the [Tendermint](https://iq.wiki/wiki/tendermint) Consensus [BFT (Byzantine Fault Tolerance) ](https://iq.wiki/wiki/byzantine-fault-tolerance)algorithm to enhance network security and facilitate consensus for block generation.  \n  \nValidators are chosen through a [Delegated Proof-of-Stake (dPoS)](https://iq.wiki/wiki/delegated-proof-of-stake-dpos) mechanism from a pool of staked [nodes](https://iq.wiki/wiki/node), aiming to ensure both efficiency and security. Their role involves validating incoming transactions, propagating legitimate ones, and executing transaction data upon achieving consensus. This process updates the network state and embeds the root hash in subsequent block headers, thereby maintaining the integrity of the [blockchain](https://iq.wiki/wiki/blockchain) ledger.[\\[2\\]](#cite-id-8y5mwwqg1z7)  \n  \n### Node as Observer  \n  \nIn Hana Network, Observers oversee transactions on external chains connected through the Gateway Function, facilitating secure data flow between Hana Network and other [blockchain](https://iq.wiki/wiki/blockchain) ecosystems.  \n  \nThey verify user transactions on external chains and coordinate their execution on Hana Network. Observers receive monitoring details from TSS Signers and follow a structured process within network epochs to handle external transactions efficiently, ensuring effective transaction monitoring and processing.[\\[2\\]](#cite-id-8y5mwwqg1z7)  \n  \n### Node as TSS Singer  \n  \nIn Hana Network, TSS Signers are responsible for managing the private keys associated with tokenized assets and services from external chains. Using a threshold signature protocol, they seek consensus from over two-thirds of validators to generate signatures, decentralizing key management to enhance security. Each external chain integrated with Hana Network maintains a distinct TSS address, ensuring operational continuity across epochs.  \n  \nThis approach aims to improve security by distributing key management responsibilities and aims to reduce costs by aggregating user operations to eliminate gas fees on transactions made on external chains. Moreover, it facilitates secure asset management on Hana Network while prioritizing transaction privacy through bastion servers.[\\[2\\]](#cite-id-8y5mwwqg1z7)  \n  \n# Products  \n  \n## Hana Gateway  \n  \nHana Gateway aims to simplify access to the [blockchain](https://iq.wiki/wiki/blockchain) ecosystem by providing a trustless on-off ramp, ensuring users retain full control over their funds without encountering hidden fees or fraud.
