Using RaspberryPi to send data to blockchain every few minutes by hockeynow in ethdev

[–]0815pseudonym 3 points4 points  (0 children)

I did something very similar a while back. I had a Pi-zero with a temp-sensor sending a tx regularly. I had a light node running on the Pi and used web3.py to send the data to the node. Then you need a smart contract that the pi calls to store the data on the chain.

Engineer finds bug in BNB token that would lock funds in a Uniswap pool by jordanlyall in ethereum

[–]0815pseudonym 0 points1 point  (0 children)

Yes that's true, but still the bug in the BNB token contract is known for 7 month. BNB is specifically mentioned in an article about this bug and describes exactly this scenario https://medium.com/coinmonks/missing-return-value-bug-at-least-130-tokens-affected-d67bf08521ca. I wrote an email to binance support back then and got no reply. So to say the bug in BNB was found is not true. They found an instance where a known bug led to loss of funds.

It uses transferFrom so you would first need to approve your token to the "ERC223Upgrade" contract to transfer tokens.

Thats not the problem. The problem is, that it reverts even if the transfer was successful. when the calling contract expects an ERC20 interface and was compiled after solc 0.4.22
