# blockchain security

## <mark style="color:blue;">qtum</mark> blockchain

<mark style="color:blue;">Qtum</mark> blockchain is a proof of stake \[PoS), unspent transaction output \[UTXO] immutable code-base, and amalgamation Bitcoin and Ethereum. Qtum blockchain deploys a virtual machine and cryptocurrency smart contracts, supporting QRC20 standard and <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token programming architecture. Synthetic Chain is fully integrated with Qtum virtual machine, and CRT Token Electrum wallet enables smart contracts processing in real time over a 32 second increments.

<mark style="color:blue;">Qtum</mark> cryptocurrency has been providing Bitcoin + Ethereum updates, and wallet updates since its development in 2015, being one of the most developed blockchain in the entire market-place. <mark style="color:blue;">Qtum</mark> combines a best of both worlds, Bitcoin UTXO code-base and Ethereum decentralized finance capabilities with PoS security, energy efficient and light blockchain. This allows <mark style="color:blue;">Qtum</mark> to operate at fast speeds, churning higher transaction output and at much lower costs (gas fees). <mark style="color:blue;">Qtum</mark> is some 1,000x more affordable than ETH network, while being capable of rendering up to 1000 transactions per second.&#x20;

## **smart contract audit**

Security of Synthetic Chain is our highest priority. To ensure we meet top security standards, <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token protocol & smart contracts are being audited by a 3rd party. The main feature of Synthetic Exchange are **Business Continuity** \[BC] policies, put in place to ensure functioning of <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token network without downtime. The results of the Smart Contract audit and Qtum Protocol Integration will become available upon request.

## bug bounty

Do to a proprietary nature of the <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token smart chain, we do not support a bug bounty program on any of the smart contracts deployed on the main-net. We do not make any of the IP available on our [Github ](https://github.com/CRYPTOKENboard)for review, Synthetic Chain is not open-source. We value the proprietary nature of Synthetic Chain and to continue to protect technological innovations at Cryptoken Board with highest regard.
