Very nice, engaging video with an enthusiastic sounding speaker. Loved the twist of explaining merkle trees through color combinations. I am trying to understand exactly how the smart contracts run. Are they only run if there is a transaction in the block currently being verified which makes an interaction with them? Like are they simply ignored if a block is created where no interaction is made with the smart contract? Also I don't quite understand the pricing. The creator of the smart contract couldn't know in advance how much memory and CPU it will need, and hence wont know how much gas to allocate for running the contract? Or is it even the contract creator who pays the gas, or is it instead whoever has an interaction with the smart contract at some later date?
@DanielFinlay
7 жыл бұрын
Very nice, you guessed both of the answers! Smart contracts only react to transactions, they cannot passively respond to things. That's why there are projects like Ether Alarm Clock, which allow you to put a bounty up to "wake up" your contract at a later time. The Ethereum Virtual Machine (VM) has a price very every operation it can perform, measured in a unit called "gas". When you send a transaction, you include two parameters: Gas price (how much ether you're willing to pay per unit of gas), and gas limit (the maximum amount of gas you're willing to pay for during the transaction). During the execution of a transaction, before each operation, there is a check to make sure this will not exceed your gas limit. If it does, it throws an error, reverting all the changes your transaction made, other than charging you the gas fees. For this reason, a person publishing a smart contract pays enough to store that smart contract and set it up, and each person interacting with a smart contract pays enough for it to run their instructions. There are some changes planned for the Metropolis (EIP 86) that will allow any account to pay the gas fees, so then if you want to make your contract cheaper to use, you could pick up the bill for your users. I hope that helps!
@erikengheim1106

Ah so simple setting up a smart contract involved instructions with a gas price. That is interesting. So if I was to speculate on the solution you describe. As a user you set a max amount of gas to prevent a faulty program from running far more instructions than you intended. Not sure if I get the max unit price for gas. I had assumed you bought the gas with ether in advance. But this makes it sound like you allocate some ether to the executing of the contract, which is then used to purchase gas in the market as needed. If there is a market? Or is gas price set by the miners, rather than traders. I assume ether price is determined largely by trading kind of like bitcoin, but that gas price might form in a slightly different way. Perhaps in relation to scarcity of computation power available on each node. E.g. if there are a lot of smart contracts running there will be shortage of gas/computation power available and hence gas price has to increase??
@DanielFinlay
7 жыл бұрын
Your intuitions are so correct that I almost think you're trolling me by asking questions. Yes, you set a max gas amount so that you limit your loss in case of a faulty program. In fact, when an error is thrown in Ethereum, you lose your gas limit x your gas price of ether. When you set your gas price, you are declaring how much you will pay the miner for processing your transaction. This creates an auction scenario, where miners do mine the highest value transactions first. Yes, this means during busy periods, there are peaks in network usage cost, much like surge pricing on uber or lyft. Last week we saw a big glut of transactions being processed, and gas costs got quite high, around 51 gwei, and that's just because the big sale of the week (Status) limited their contributors to using 50 gwei per unit of gas. A unit of gas is just the smallest indivisible amount that is charged (in ether) to use the Ethereum computer. Every operation has its own gas cost, and they're priced to reflect the performance cost on the validator's computer. For example, adding two numbers is cheap, storing a number for eternity is expensive. Forgetting a number gives you a refund! That's all called "metering" and you can look up the price per operation online.
@DanielFinlay
7 жыл бұрын
Bonus fun fact about how operations are priced: On the first day of Devcon 2, there was an attack on the Ethereum network where the attacker slowed down the network cheaply because the exponent operation was too cheap for how fast it computed on one client, bringing geth users down for the morning, until a patch was released.

is this color-metaphor really correct? I never heard you can get the same color by mixing _two_different_sets_ of colors. I.e., you have A+B giving you C and you have D+E resulting into the same C. Aren't receipts for colors deterministic? Meaning you can always calculate back which two colors needed to get the one you need. Of course you don't know if it was _two_ colors in receipt. It might be 10 colors mixed together. But this is not what was depicted on the screen :)

How exactly are you going to solve scalability issue ? since it's decentrelized , it means every transaction needs to run through every node (or process/verify ) right ? Don't you think that as this platform grows bigger bigger the speed of all those contracts and transactions would be really really slow since it needs to be verified by all nodes ?
@DanielFinlay
7 жыл бұрын
Moon Bilguun There are several strategies for scaling, and they all have to do with ways for people to not verify every transaction. You can essentially have a consensus protocol for individual branches of the merkle tree, and join them with a lower root consensus protocol. Maybe a good subject for another talk, although there are so many projects on it, I'm not a full expert right now.

The key/account management is a pretty different topic than the merkle data structure of the blockchain. The merkle tree is how the information is all stored, but the clients decide what is a valid new state, and this enforces rules about account ownership, including key signatures.
