It is indeed possible to improve Solidity, the underlying compiler, and even having new languages altogether, while being backwards compatible (at least, from the EVM standpoint). On the first two cases (Solidity + compiler improvements), better static analysis could identify reentrancy cases, as well as integer overflow/underflow. This is not much different that what mythril and slither already do. Alternatively, these could be pushed to the code generator component of solc as a means to generate code that reverts in case any of the two occur during runtime, with the downside of higher gas costs per transaction.

Domain architecture of Family 9417 protein members where signal peptides (blue), CFEM Interpro domains (green), GPI anchor sites (orange), and predicted transmembrane domains (red) are indicated for each protein. Three proteins colocalize together on scaffold 43, the remaining on scaffold 5 (indicated on right).
Abstract:Methyl tert-butyl ether (MTBE) is a widely used gasoline additive that has high water solubility, and is difficult to separate from contaminated ground and surface waters. We present the development in functionalized carbon nanotube-immobilized membranes (CNIM-f) and graphene oxide-immobilized membranes (GOIM) for enhanced separation of MTBE via sweep gas membrane distillation (SGMD). Both types of modified membranes demonstrated high performance in MTBE removal from its aqueous mixture. Among the membranes studied, CNIM-f provided the best performance in terms of flux, removal efficiency, mass transfer coefficients and overall selectivity. The immobilization f-CNTs and GO altered the surface characteristics of the membrane and enhanced partition coefficients, and thus assisted MTBE transport across the membrane. The MTBE flux reached as high as 1.4 kg/m2 h with f-CNTs, which was 22% higher than that of the unmodified PTFE membrane. The maximum MTBE removal using CNIM-f reached 56% at 0.5 wt % of the MTBE in water, and at a temperature of 30 C. With selectivity as high as 60, MTBE recovery from contaminated water is very viable using these nanocarbon-immobilized membranes.Keywords: MTBE separation; functionalized carbon nanotube immobilized membranes (CNIM-f); graphene oxide immobilized membranes (GOIM); sweep gas membrane distillation (SGMD); flux enhancement
The airdrop hunting attack uses multiple new accounts to call the airdrop function in order to obtain airdrop coins, and attackers transfer them to their account to achieve wealth accumulation. This attack is relatively common that as long as it is a contract with an airdrop function, it can make multiple profits. The first automated attack was the Simoleon contract. As Figure 9 shows, the contract was designed to give some amount of ether to initialized an account, so the attacker thinks that we can create a few more accounts to get rewards, then transfer all the money to one account. The attacker write attack the contract and create many temporary contracts, and call this function in these contracts.
According to the design of Ethereum, when the smart contract is deployed or the function in the smart contract is called, the execution of the contract code needs a certain amount of gas to ensure that the calculation is completed completely. At the same time, the Ethereum system limits the maximum total amount of gas consumed by each block, and the total amount of gas of all transactions in the block cannot exceed the maximum total amount of gas in this block. Once an operation in an intelligent contract consumes a lot of gas, resulting in the consumed gas value reaching the maximum total amount of gas in the block, the operation will not be successfully executed, and all processes depending on the operation will fail, so the contract cannot normally complete other functions, resulting in a denial of service state. As Figure 11 shows, transferring money to everyone at once is likely to result in reaching the gas limit of ethereum blocks. Usually, this denial of service attack occurs when a contract developer does not consider the block gasLimit and introduces the operation of modifying dynamic data structure variables such as arrays whose size will change with time. After a block is mined, an attacker can issue multiple transactions at a higher gas price immediately, and then use the above operations of the contract to consume the gas limit of the whole block, so that the block does not contain any other transaction before a certain time, thus preventing other users from using the functions of the contract normally.
To prevent the false top-up attack, we judge not only transaction success but also whether the balance of the top-up wallet address increases accurately. This judgment can be made through the Event log. Many centralized exchanges, wallets, and other service platforms obtain the transfer amount and judge the accuracy of the transfer through Event logs. However, we need to pay special attention to the evil situation of the smart contract, because the Event can be written arbitrarily, and it is not a mandatory default option that cannot be tampered with. The required and asserted methods can also be used that an exception will be thrown directly to interrupt the execution of the subsequent instructions of the contract when the conditions are not met.
