The main features of GateChain ecosystem can be listed as follows:

  1. Transfer/payment:Using a wallet or client-side Apps, users can send and receive GateChain Token GT, as well as other popular onchain assets.
  2. Asset issuance: Users can issue and use their own tokens (e.g., GT) to digitalize and manage their assets. For more details, visit Asset Management.
  3. Decentralized cross-chain transaction:GateChain provides support for high-performance decentralized trading among different digital currencies.
  4. Asset safe storage: With a uniquely designed vault account and a clearing technology, an account can have comprehensive protection and support revoking /clearing operations targeting abnormal transactions. For more details, visit Transaction Protection.
  5. Multi-signature: Multiple signers can share ownership of one account, and get customized management over their digital assets, which best fit the enterprise demands. For more details, visit Multi-signature.
  6. POS staking reward:GT works as a stable incentive for users participating in PoS staking, which safeguards the robustness of underlying blockchain.

GateChain Blockchain

GateChain is a novel next-generation public blockchain, focused on onchain asset safety and decentralized exchange. With unique Vault Account technology and its supporting transaction model design, GateChain has implemented a guaranteed safe clearing mechanism, creatively solving the challenging problem of asset theft and missing private keys. It also supports decentralized trading and cross-chain transfer among other core applications. Compared with traditional blockchains, such as Bitcoin and Ethereum, GateChain focuses on on-chain asset safety. It creatively proposed a bunch of novel concepts, including Normal AccountVault AccountRetrieval AccountClearing HeightRevocable Delay PeriodAddress TypeTransaction Type.

GateChain DEX

GateChain DEX is a decentralized exchange based on GateChain. It has matching engines of ultra-high performance and low participating cost, thus providing users with a safe, quick and transparent trading experience. It also supports cross-chain transfer for multiple currencies.

Anyone who has full control over the private key of his account can exchange freely. GateChain DEX uses private own encrypted wallets or hardware wallets to safeguard users’ assets and solves the trust issue that is present for centralized exchange.

GateChain Token

GateChain Token GT is the native currency of the GateChain mainnet. It is used to pay transfer fees on GateChain’s network and works as the incentive reward for PoS staking. It is fundamental to GateChain’s network.

GateChain Wallets

GateChain provides various wallet applications for individual, professional and enterprise users.

  • During the testnet phase, GateChain provides desktop wallets for Windows and Mac OS; professional users can also access and test using API.

  • During the mainnet phase, GateChain will provide command-line wallet, mobile wallet for Android and iOS, Web wallet, multi-signature wallet, and hardware wallet, to cater to individual, professional and enterprise users.

Typical Application

GateChain offers two types of accounts, Normal Account and Vault Account, to meet the efficiency demand in daily payments and safety demand in asset storage. Normal Account allows instant payment and transactions are irreversible. It does not allow restoring a lost private key, similar to the features of a bitcoin address. While the onchain Vault Account, a major novel creation of GateChain, allows revocable transaction and private key restoration. By combining both types of accounts, GateChain provides complete safety features to its users.

1. Individual assets management

GateChain provides individual users with two types of accounts, a Normal Account and a Vault Account. Normal Account is used to store a tiny fraction of assets for daily use while Vault Account is used to store the majority, not in immediate need. The vault account can set a transfer delay period, 2 days for example.

For everyday transactions, users can use assets in the Normal Account just like they are using bitcoin: a transaction is confirmed upon payment and is irreversible. In the worst case when the Normal Account’s private key is lost or stolen, the loss is limited to the small portion. Risk is still under control. When the asset in the Normal Account is insufficient, they can transfer more from the Vault Account based on his plan. The transfer will be received with a 2 days (example) delay. If theft is found during the delay period, he can simply initiate a "Revoke" request. The stolen transaction will be revoked and moved to “Retrieval Account”. Loss is avoided.

2. Legacy or Grant auto-release:

Digital asset inheritance has been a headache for many as it can not be handled by a middle man such as bank assets and real estate under the existing applicable laws. The private key of digital assets is usually kept by the holder himself for security reasons. Without complicated processing procedures, digital assets will be frozen forever following the death of the holder and leave his lawful heir no way to access to his legacy. Vault Account at GateChain supports releasing digital assets at a preset future time point to a predefined beneficiary, without worries about private keys missing or theft during this period. As long as one can set a digital asset distribution ratio and release time when he is able to do it, his digital asset will be transferred to his named beneficiary accordingly. This asset processing method can also be used in other scenarios like scheduled fund granting. For example, if parents want to give their children some digital assets when they are 18 years old to fund their development after they have grown up. The parents can specify at their own Vault Account to send a certain amount of digital assets to their children when they are 18 years old.

3. Safe Storage of Bank Asset

Bank asset storage demands an extremely high level of safety. The prevailing mechanisms in the blockchain industry are cold storage and hardware wallets. But these mechanisms can not 100% guarantee the safety of blockchain asset, especially when it comes to asset risks arising from private key damage. These issues have significantly limited the possibility of blockchain asset massive adoption.

With GateChain’s Vault Account, the bank can set a longer transfer delay time to significantly reduce asset storage risk. Besides, GateChain also supports Vault Accounts cascading, which can exponentially reduce risks of theft.

In practice, GateChain can achieve an approximate 100% safety for asset storage at a very low cost. Just like the possibility of Bitcoin being brute force attacked is close to zero in practice, though not 100% safety in principle, it is already 100% safety in practice. In addition, pocket money wallet and hardware wallet technologies can still be used to give it further protection.

Academic Research

To promote the development of blockchain technology and its applications in the real world, GateChain research focuses on studying principles and applications around onchain trading safety.

The major innovation of GateChain is:

  • Put forward and implemented an on-chain “Vault Account”. This type of account has safety features allowing revocable transactions and damaged private key restoration, thus providing a novel blockchain safety solution to individuals, enterprises, and asset sensitive banks.
  • A transaction model that supports retractable logic which called RTM(Revokable Transaction Model).

Terms

As an innovative public chain focusing on on-chain asset security, GateChain introduces a number of new concepts. GateChain hopes to help users understand GateChain’s security logic more comprehensively by providing the description of the concepts. Also, for the consideration of transaction security, GateChain innovatively put forward the identification of address type and transaction type to facilitate the user to effectively identify different account type and transfer type, to avoid user mis-operation.

GateChain Basic Concepts

GateChain is a novel public chain. Its principal research has introduced many novel concepts that form the principle fundamentals for building complete self-consistency in assets safety.

  • Normal Account:Account similar to a Bitcoin address that can store assets and is suitable for daily use. An asset in this type of account can be sent instantly and is irreversible once confirmed on the blockchain. A lost private key can not be restored.
  • Vault Account:GateChain’s novel creation. This is a new type of account that allows revocable transaction in the case of theft and private key restoration in the case of lost or damaged private key. Transfer of assets in this type of account have to wait for a preset period of time. It is suitable for storing and protecting a large amount of assets that are not for immediate use.
  • Revocable Delay Period :The time duration within which transaction transfer from vault account is revocable. During this time period (calculated by blocks), recovery of a transaction is possible by initiating a "revoke" operation to return the transaction to “Retrieval Account’.
  • Retrieval Account:the preset account bound to a Vault Account. When a transaction in the vault account is revoked, the transaction asset will be moved to this account.
  • Clearing Height:it is a future time. At the time when this future block height is hit, the asset in the account will allow clearing.
  • Revoke: When the transaction initiated from Vault Account is still in the revocable delay period, the “revoke” operation can be initiated to return the asset to “Retrieval Account’.
  • Revocable Transaction:any transaction initiated from Vault Account is a revocable transaction, which allows for revoking to move the asset to “Retrieval Account” during the revocable delay period. After the revocable period, the transaction can not be revoked.
  • Irrevocable Transaction:Transactions initiated from Normal Account. It is irreversible once it is confirmed by blockchain.

GateChain Address Types

GateChain has two main account types, Normal Account, and Vault Account, with a different identifier at the start in their addresses.

  • Normal Account:start with “gc’’. “gc1” indicates a single- signature Normal Account, and “gc2” indicates a multi-signature Normal Account.
  • Vault Account:start with “vault’.“vault 1” indicates a single- signature Vault Account, and “ vault2” indicates a multi-signature Vault Account.

With the address identifier mechanism invented by GateChain, the recipient account can easily identify the sending account's type and set the confirmation requirement accordingly. If it is from a Vault Account, confirmation is safe only after a revocable delay period.

GateChain Transaction Types

GateChain has many transaction types. To identify different transaction types efficiently, GateChain creatively provides a transaction type identifier.

Below are identifiers different transaction types start with:

  • Irrevocable Pay:“INREVOCABLEPAY-”
  • Revocable Pay:“REVOCABLEPAY-”
  • Account Set: “ACCOUNTSET-”
  • Vault Create:“VAULTCREATE-”
  • Revoke: “REVOKE-”
  • Vault Clear:“VAULTCLEAR-”
  • Untitled: “BASIC-”
