📜 [專欄新文章] Gas Efficient Card Drawing in Solidity
✍️ Ping Chen
📥 歡迎投稿: https://medium.com/taipei-ethereum-meetup #徵技術分享文 #使用心得 #教學文 #medium
Assign random numbers as the index of newly minted NFTs
Scenario
The fun of generative art NFT projects depends on randomness. The industry standard is “blind box”, where both the images’ serial number and the NFTs’ index are predetermined but will be shifted randomly when the selling period ends. (They call it “reveal”) This approach effectively solves the randomness issue. However, it also requires buyers to wait until the campaign terminates. What if buyers want to know the exact card right away? We’ll need a reliable onchain card drawing solution.
The creator of Astrogator🐊 isn’t a fan of blind boxes; instead, it thinks unpacking cards right after purchase is more interesting.
Spec
When initializing this NFT contract, the creator will determine the total supply of it. And there will be an iterable function that is randomly picking a number from the remaining pool. The number must be in range and must not collide with any existing ones.
Our top priority is accessibility/gas efficiency. Given that gas cost on Ethereum is damn high nowadays, we need an elegant algorithm to control gas expanse at an acceptable range.
Achieving robust randomness isn’t the primary goal here. We assume there’s no strong financial incentive to cheat, so the RNG isn’t specified. Implementers can bring their own source of randomness that they think is good enough.
Implementation
Overview
The implementation is pretty short and straightforward. Imagine there’s an array that contains all remaining(unsold) cards. When drawIndex() is called, it generates a (uniform) random seed to draw a card from the array, shortens the array, and returns the selected card.
Algorithm
Drawing X cards from a deck with the same X amount of cards is equal to shuffling the deck and dealing them sequentially. It’s not a surprise that our algorithm is similar to random shuffling, and the only difference is turning that classic algo into an interactive version.
A typical random shuffle looks like this: for an array with N elements, you randomly pick a number i in (0,N), swap array[0] and array[i], then choose another number i in (1,N), swap array[1] and array[i], and so on. Eventually, you’ll get a mathematically random array in O(N) time.
So, the concept of our random card dealing is the same. When a user mints a new card, the smart contract picks a number in the array as NFT index, then grabs a number from the tail to fill the vacancy, in order to keep the array continuous.
Tweak
Furthermore, as long as the space of the NFT index is known, we don’t need to declare/initialize an array(which is super gas-intensive). Instead, assume there’s such an array that the n-th element is n, we don’t actually initialize it (so it is an array only contains “0”) until the rule is broken.
For the convenience of explanation, let’s call that mapping cache. If cache[i] is empty, it should be interpreted as i instead of 0. On the other hand, when a number is chosen and used, we’ll need to fill it up with another unused number. An intuitive method is to pick a number from the end of the array, since the length of the array is going to decrease by 1.
By doing so, the gas cost in the worst-case scenario is bound to be constant.
Performance and limitation
Comparing with the normal ascending index NFT minting, our random NFT implementation requires two extra SSTORE and one extra SLOAD, which cost 12600 ~ 27600 (5000+20000+2600) excess gas per token minted.
Theoretically, any instantly generated onchain random number is vulnerable. We can restrict contract interaction to mitigate risk. The mitigation is far from perfect, but it is the tradeoff that we have to accept.

Surprise...the long hair has finally had a trim! To usher in the new school year, I’ve decided to go with a classic look - I can definitely say that I’m feeling fresher with this new look now. Back-to-school ready? Check! ✅
Now that school has started once more, I’ve had to set aside a little less time for things like my poetry, songwriting, and other rekindled passions. This school year, I enter Fourths, or Year 10 - the fourth year of secondary school here in the UK. This term marks the start of my journey into the IGCSE course, which I’ll be examined in at the end of my next academic year. In total, I’m now studying 9 subjects: English, Maths, Chemistry, Biology, Art, Drama, French, Latin and Ancient Greek. Yep, you read that right, I’m taking 3 languages as electives for my IGCSEs! 🤩
Now that the first week of school has passed, I’ve been able to do a few interesting things to kick off everything. The most notable one so far is that I have decided to audition for the Junior and Senior Production. Since I’m in Fourths, this year I can choose to audition for both the Junior and Senior Production. The Junior Production is an original play titled ‘Burn’, and for the Senior, it’s none other than the classic ‘Pride and Prejudice’! So far, I’ve auditioned for the Senior Production, and my audition for the Junior Production is this week - wish me luck! ✨
But honestly, that’s not all I’m excited about. Although these next two years will be incredibly busy now that we’re working towards our IGCSEs, I have a feeling that all of the academic and co-curricular parts of my school life now will prove to be invigorating and full of exciting opportunities. Here’s to a new academic year! 🙌🏻
Looking forward,
O. Mukhtar O. Mukhlis

好開心能夠跟 行走的CD合唱
天籟一般的歌聲
實在太好聽了
歌詞
You’re crying in your bedroom
Cos I’ve gone and left you
Wish I never met you
Don’t know what you’ve got until it’s gone
You’re crying in your bedroom
Easy to forget you
Done this to yourself
And now I’m gone
Now I’m celebrating
My god I bet you hate it
I can’t believe I waited for you for so long
You’re crying in your bedroom
Cos I’ve gone and left you
Don’t know what you’ve got until it’s
Go-o-o-o-one…
