4thTech, multi-blockchain data exchange

# FOUR TOKEN | ecosystem native multi-chain asset

Logo

A multi-chain asset and technical component that enables 4thTech tokenization with TX discount staking, right to access and governance signaling.

# FOUR Smart Contract

FOUR's smart contract design implements:

  • ERC-20 interface that can be used with any Ethereum native blockchain wallet, furthermore the ERC-20 standard allows FOUR to integrate with most of EVM compatible Layer 2's or Side Chain's;
  • embedded TTS interface (i.e. token teleportation-service), that enables wallet accounts to use ERC-20 FOUR natively as gas;
  • MTO (i.e. multiple-transfer option), settlement service that conserves blockchain network transactions and bundles signed multiple transactions together and settles them on the blockchain as one transaction;
  • ability for governance signaling.

# Utility

4thTech token (i.e. FOUR) is the ecosystem native utility token planned to be one of the technical components needed for the 4thTech ecosystem tokenization. Besides unique smart contract embedded features; (1) TTS interface (i.e. token teleportation-service); (2) MTO (i.e. multiple-transfer option), and; (3) GAS option, the FOUR token is being used as the primary means to enable software licence access and community signalling.

# History

Developed and deployed in 2018, FOUR acted as one of the technical components needed for the 4thTech ecosystem tokenization on Ethereum network, combining three technical utility features:

  • embedded TTS interface (i.e. token teleportation-service);
  • MTO (i.e. multiple-transfer option);
  • GAS feature.

During the past few years, the FOUR token evolved and became a multiverse asset occupying the space of multi-chains, while being used as the primary means to enable software licence access and community signalling.

# Supply

To serve the project's tokenization 400m ERC-20 FOUR utility tokens were deployed on Ethereum main-net in 2018. The current circulating supply represents close to 38% of the total supply and consists mostly of long term community token holders.

  • Research & Development: 30% (2-4 years vesting)
  • Team: 15% (2-4 years vesting)
  • Private Partners: 12% (2-4 years vesting)
  • Marketing: 5%

# A multi-blockchain asset

Cross-chain interoperability of ERC-20 FOUR with other blockchains essentially increases the decentralisation of liquidity and unlocks a universe of possibilities for further tokenization development. The users instantly benefit from lower fees and the native economy of the bridged blockchain. With an unchanged total and circulating token supply, the FOUR ERC-20 exists on its native Ethereum blockchain, while a wrapped synthetic version exists on the bridged blockchains.

# BEP-20 FOUR, a multiverse asset on the Binance Smart Chain (i.e. BSC)

logo BSC

Cross-chain interoperability of FOUR tokens opens a multiverse of new possibilities. The bridging of ERC-20 FOUR to BEP-20 FOUR token increases project recognition, liquidity and unlocks a universe of possibilities such as:

  • access to extreme transaction speeds with 1000x lower TX fees;
  • access to the BSC economy;
  • ability to enable new tokenization models.

Binance Smart Chain

Binance Smart Chain or short BSC is the second blockchain launched by Binance. Binance originally launched the Binance Chain to facilitate Binance Coin (i.e BNB) and transactions on their decentralized Binance exchange (i.e. Binance DEX). Focusing on reliability, transaction speeds and trade efficiency, the original Binance Chain does not support smart contracts. To enable smart contracts and programmable compatibility the Binance Smart Chain was released. The BSC also features compatibility with the Ethereum Virtual Machine. Both chains are completely independent and exist in parallel serving specific functions.

# BEP-20 token

The BEP-20 is a Binance Smart Chain token standard specifically designed for decentralized finance and decentralized applications on the BSC.

# FOUR as BEP-20 wrapped token

The FOUR tokens were originally deployed as ERC-20 on the Ethereum chain. On the Binance Smart Chain, the FOUR tokens appear as wrapped equivalents, a synthetic version of the original asset.

Note

According to the Binance Academy, a wrapped token is a cryptocurrency token pegged to the value of another crypto. It’s called a wrapped token because the original asset is put in a wrapper, a kind of digital vault that allows the wrapped version to be created on another blockchain. The benefit of the wrapped tokens is the ability to circumvent the limitation of the non-native blockchain assets. A wrapped BEP-20 FOUR (i.e. Binance Smart Chain token standard) is a tokenized pegged version of the ERC-20 FOUR (i.e. Ethereum token standard) on the Binance Smart Chain.

# ERC-20 FOUR to BEP-20 FOUR BRIDGE

When sending ERC-20 FOUR to Binance Smart Chain, the cross-blockchain bridge is needed. The Bridge enables the cross-chain token bridging in both directions. The smart contract locks the ERC-20 FOUR sent from the Ethereum, while the equivalent amount of FOUR BEP-20 is minted on BSC. When the BEP-20 FOUR needs to be bridged back to ERC-20 FOUR, the smart contract puts in a BEP-20 FOUR burn request to the Bridge, and the ERC-20 FOUR are released from the reserves. This process ensures that the total and circulating token supply don’t change.

# SPL FOUR, a multiverse asset on the Solana blockchain

logo SPL

Cross-chain interoperability of FOUR tokens opens a multiverse of new possibilities. The bridging of ERC-20 FOUR to SPL FOUR token will increase project recognition, liquidity and unlock a universe of possibilities such as:

  • extreme transaction speeds with 1000x lower TX fees;
  • access to the Solana economy;
  • new innovative tokenization models.

Note

Solana is the next generation censorship-resistant blockchain with extreme transaction speeds and low cost, therefore perfect for transaction and other high-speed blockchain applications. Solana leverages Proof of History and several other breakthrough innovations to allow the network to scale at the rate of Moore’s Law (Solana.com, May 2021).

# SPL token

According to Solana, the SPL Token program is the token standard of the Solana blockchain.

# FOUR as SPL wrapped token

The FOUR tokens were originally deployed as ERC-20 on the Ethereum network. While the FOUR ERC-20 exists on its native Ethereum blockchain, a wrapped synthetic equivalent version of the original asset SPL FOUR exists on the Solana blockchain.

# ERC-20 FOUR to SPL FOUR BRIDGE

When sending ERC-20 FOUR to the Solana blockchain, the cross-blockchain bridge is needed. The Bridge enables the cross-chain token bridging in both directions. The smart contract locks the ERC-20 FOUR sent from Ethereum, while the equivalent amount of SPL FOUR is minted on Solana. When the SPL FOUR needs to be bridged back to ERC-20 FOUR, the smart contract puts in an SPL FOUR burn request to the Bridge, and the ERC-20 FOUR are released from the reserves. This process ensures that the total and circulating token supply doesn’t change.

Note

The Solana Wormhole bridge enables ERC-20 FOUR to bridge to SPL FOUR available on the Solana blockchain. The Wormhole bridge uses decentralized cross-chain oracles (i.e. guardians) operated by a set of node operators that include top Solana validators and other ecosystem stakeholders whose incentives are strongly aligned with Solana and Serum (Solana.com, May 2021).

The exchange (i.e., swap) of the FOUR token is available on the designated exchanges and de-fi protocols and it is not a public offering of equity or debt and, consequently, does not fall under securities or any prospectus regulation. The FOUR tokens are not securities as defined under applicable laws. Therefore, the FOUR tokens have not been registered with any competent regulator. The exchange (i.e., swap) of the FOUR tokens is unregulated. Changes to legislation in the most relevant jurisdictions in the world are closely monitored. Appropriate actions will be undertaken to act accordingly if regulatory changes impact the four-token exchange and operations.
