In terms of congestion, however, it is the Status token sale that created the most on Ethereum:
— suitable for projects with smaller funding goals
The strong hype around Bancor led to a significant increase in pending transactions, as buyers attempted to acquire BNTs. Consequently, the whole Ethereum network was impacted for many hours from such a rush Pending transactions end up in a dedicated memory space on the network’s nodes, which is more commonly called “backlog” or “transaction pool.” When this space is saturated, transactions take greater amounts of time to be validated The Bancor team tried to modify the smart contract to stop the token sale at 250,000 ETH, but even they couldn't do it because of the congestion. This led to the ICO lasting two hours more than initially planned
308,488
Theoretical throughput with Raiden Network: 
Broken record: highest ever number of daily transactions on Ethereum -
Average limit in July 2017:
More on ICOs
Since Ethereum makes it relatively easy for developers to build complex smart contracts and decentralized autonomous apps (DApps) and given the rising price of ETH, it became the platform of choice for these ICOs
6,700,000 gas
13 per second
The Status Token Sale
up to one mln per second
 
Planned maximum time frame: 14 days
As a result, the Ethereum network got clogged up and started slowing down significantly. This network paralysis was so strong that many exchange platforms temporarily blocked ETH withdrawals
24 hours
Actual time:
Powerful way of boosting Ethereum's computational capacity
Sharding: a theory that suggests that each node would only need to be a validator of a specific portion of the Blockchain, and acts as a light client for the rest of the Blockchain
MyEtherWallet, one of the most popular ETH wallets, even displayed a note discouraging users to send ETH if their transaction was not urgent
To keep track of the upcoming ICOs, and monitor how they impact the Ethereum network:
ICO Calendar
The ICO Mania and  its Consequences on Ethereum
Look at alternative platforms for ICO launches
Sometimes, if an ICO is incredibly popular, the Ethereum network may get clogged, which not only makes that ICO go less smoothly but also creates problems for all other users of Ethereum who aren't even participating in the fundraiser
The Bancor Token Sale
Here are recent examples of ICOs which have caused this problem
Due to the complex rules managing the excess of pending transactions in the backlog, some users even saw their ETH disappear in the parallel dimension of transactions that have been validated but never mined, with big delays in the failure of these transactions and the refunding of users
What is an ICO?
Start date: 12 June 2017
An ICO is a recently emerged concept of crowdfunding Blockchain projects
3 hours
Raised:
Waves platform works differently but would allow for much of the same functionality as a given smart contract on Ethereum
Raiden Network
Ethereum Classic is aware that ICOs will increase on their platform over time (equal level of development as Ethereum)
Money raised:
Contributors can then use these tokens, hold them or sell them for profit
The in-progress Raiden Network, an Ethereum implementation inspired by Bitcoin's Lightning Network, adds an extra layer to the Ethereum Blockchain that could increase transaction throughput
How can investors and companies solve Network Congestion?
It's an event in which a company issues its own cryptocurrency, and sells a number of these tokens to its intended audience
300,000 ETH — $90 mln
390,000 ETH — $153 mln
Current throughput:
Long-term solutions have yet to be looked at, but certain individual ICOs (iDice) have decided to tell users to increase the “gas” they use to propel their investments. Gas is the internal pricing for running a smart contract or submitting a transaction to Ethereum. However, there is a gas limit and miners on the network decide what the block gas limit is.
