The winner of our ONE MILLION GWEI retweet contest is YourMillenialDad 𒌋𒉈𒂗 ! Congrats friend, please PM us your details. Appreciate everyone who participated spreading Solidity knowledge across the Twitterverse 💯🌈🦄

Solidity maps can contain other maps. "A map to a map" is used within the ERC20 token standard: mapping(address => mapping (address => uint256)) allowed; #Ethereum

Solidity Tips Woohoo 🙌🏽 What a cool little surprise for a Thursday! Much gratitude and appreciation for you guys. Keep on #educating🤓🧠🤯

No Blockchain Is an Island 🏝bit.ly/2F1Iuc7

We all know this! Which is why we strive for safe, secure smart contracts. technologyreview.com/s/610392/ether…

Events are defined within the smart contract, and can be emitted when something important happens. Define: event LogDepositMade(address accountAddress, uint amount); Fire within a function: LogDepositMade(msg.sender, msg.value); #Ethereum

Parents - is your teen texting about price action? Watch out for these commonly used terms: LOL - Lots Of Liquidity WTF - What Time Frame ASL - Asian Session Lows LMAO - Lows Made Above Orderblock STFU - Support Tested From Underneath ROFL - Retail Orders Forming Lows

New firmware update 1.4.1 available for the Nano S! ledger.fr/2018/03/06/new…

Too many people are racing to start crypto projects and not enough people are racing to solve actual problems.

We can find out how much ether the caller of our contract has by checking 'msg.sender.balance' #Ethereum #Blockchain #smartcontracts

Events are inheritable members of contracts. When emitted, the arguments are stored within the transaction log. #ETHEREUM #smartcontracts

For all assembly fans out there, great read! arvanaghi.com/blog/reversing…

events are declared using the 'Event' keyword. Create many different events for debugging, or just to keep an eye on your contracts :) event Deposit ( address indexed _from, bytes32 indexed _id, uint _value ); #ETHEREUM #smartcontracts

events can have at most three parameters designated as 'indexed'. This allows us to search for these parameter values. It is also possible to filter for specific values via web3. #ETHEREUM #smartcontracts

For a complete example of events in Solidity, check out this contract: buff.ly/2GaanP4 #ETHEREUM #smartcontracts

#Blockchain can get pretty technical, even for our technical writer Micah Dameron. He recalls how he first made sense of the #Ethereum Yellow Paper and explains his motives for the Beige Paper––a more approachable version for the larger crypto community. media.consensys.net/rediscovering-…

A bit of positive news for #Ethereum.... x.com/coinbase/statu…

Want to _really_ know Ethereum down to the lowest bits? Read the technical specification! For a gentler introduction than the 'yellow paper' , check out the ' Ethereum beige paper' buff.ly/2GbbpLz #ETHEREUM
