The Red Belly Blockchain

The Red Belly Blockchain (RBBC) is an unforkable blockchain able to commit more than 600K transactions per second with a latency of few seconds. As opposed to mainstream public blockchains, it is not subject to double spending - when an individual successfully spends their money more than once - because its chain of blocks never forks. As opposed to consortium blockchains, it does not bottleneck when numerous clients issue transactions at the same time, thanks to its leaderless consensus algorithm.

  The Ethereum blockchain has gained popularity for its ability to implement Initial Coin Offerings (ICOs), whereby a buyer enters a market order agreement with a seller in order to purchase some tokens at an agreed upon price. The booming popularity of ICOs in 2017 has raised new challenges on the difficulty for many buyers to purchase tokens whose supply is often limited to a predetermined quantity or period of time.
  
  We study the impact of a series of ICOs, including a popular one that raised $35M in less than 30 seconds, on the Ethereum service providers or miners. By combining our analysis of the fees with the block gas limits in Ethereum, we identified multiples factors that contribute to the latency of a transaction. Our results show that while buyers incentivise miners generously to include their transactions during ICOs, the supply and demand of the service were the predominant factors for inclusion.
