🚨🤍 𝗡𝗘𝗪: Yan Diomande emotional letter to his late sister:

"Dear Roxane,

Remember when somebody bought me a fake United jersey, and I wrote Ronaldo 7 on the back with the black marker?"

"We didn’t know rich or poor. We just knew happiness."

"Remember 25 people sleeping in one house back in Abidjan? Mum wanted to watch her soap operas. Everyone else wanted to watch movies. Remember how I always used to fake like I was asleep and then go into the TV room after midnight? I’d put the TV on real low. Just like 2 volume bars. I’d watch football in the dark and dream."

"Remember when the adults saw me playing football in the dirt and nicknamed me “Roberto Carlos” because of how hard I would shoot? And remember how I was secretly so mad about it, because CR7 was my idol?"

"Remember when I went to play so far from home? I was 9 years old. Inter Foot Sud Comoé, all the way near the Ghana border. Just a little boy on his own. I don’t know if I ever told you this story, but me and the other kids used to go into the village and steal potatoes because we were so hungry. We did a “bank heist.” Two kids distracting the shop owner, and 18 other kids running out with two potatoes. They weren’t even good. But they tasted amazing. Hahahah. It’s still my favorite thing to eat. Boiled potatoes with some oil. It reminds me of those times."

"Remember when I got my first real football boots, and I used to sleep with them? Growing up, I always played in those white plastic sandals. Even when I go back home now, I still play in them. It’s our tradition."

"Remember when I would come back home, and you would tell my friends from the neighborhood, “Why did you stop training? Yan is not going to buy you cars. You have to keep working."

"You were 10 years old, and already my agent."

"Remember how we used to sit and dream about moving to France? How we were going to go shopping and get our own apartment and I was going to be a rich footballer with cars and a big house, and you wouldn’t have to worry about nothing. You were the one who always believed that I could be the next Cristiano, when everybody else laughed."

"Remember when I moved to America for high school at 15, and I was so homesick? I didn’t know what anybody was saying for months. They sat me next to a French kid, and he tried to translate everything the teacher was saying. Remember when I called you, saying, “You won’t believe it, the kids here argue with teachers."

"Back home, you know we wouldn’t even dare to blink at our elders."

"Remember when I couldn’t believe the kids were smoking after school? You used to say it sounded like I was in an American TV show."

"Remember when they took me on trial at Bournemouth? At Chelsea, Rangers, Olympiacos, Crystal Palace? Eze and Olise even came up to me after one training and said, “Yo kid, you’re really good.”"

"But they still didn’t sign me."

"Even the B teams in the MLS didn’t want me. I didn’t even know why. They never gave me a reason. The adults handled everything. They just kept taking me all around Europe, and everybody kept saying no."

"My visa was up. My dream was over. They sent me back to Africa, and we cried together."

"You were the one who never stopped believing. A few weeks later, I signed for Leganés and we cried different tears."

"That was back when I used to have emotions. Now, I don’t feel anything. It’s like I’m not even human. Since you died, I’m just blank."

"I don’t even think I shed a tear the day they told me that you were gone. I was just in shock."

"It was a few weeks after I made my debut for Leganés. Who makes their debut at 18 against Real Madrid? It was too crazy. It was a dream."

"And then it was a nightmare. Someone kept calling me from back home. I was annoyed. I didn’t understand why they kept calling me."

"I picked up, and they didn’t even soften it. You know how it is back home. No emotions. Just……..

“Your sister is gone.”
“What?”
“She died.”
“What are you talking about?”
“Somebody put something in her drink at a party, and she never woke up. She is gone.”

"You were 15."

"15."

"I never got any answers. I don’t know if I want to know why. Maybe it was jealousy. Maybe it’s just something that happens in our country. Maybe I could have protected you. I don’t know."

"I try to trust God’s plan. It’s all I can do. I don’t try to forget, because I know I won’t forget. All I can do is use the pain to work harder, and to do everything we dreamed about."

"I wrote this because I can’t speak about it. I wrote this because I want you to know that I will make sure that you live on. I will make sure that everybody knows your name. The whole world."

"Everything I do on a football pitch, it’s for you."

"So much has happened since I last saw you…… You would not even believe it. I don’t know if I believe it."

"You know what’s crazy? After my debut against Madrid, I actually swapped shirts with Mbappé. Remember when we used to watch him on TV, and you’d say, “Mbappé? Yeah, he’s good. But my brother is better.”

"I was wrong about one thing. I don’t want to be rich. I see what it does to people, even to family. When I was at Leganés, everything I was earning, I was sending home. It got to the point where I didn’t even want money anymore. It was just a burden. They never stopped asking. I guess they thought I was a millionaire already. I didn’t even have an apartment. I was living at the training ground in a room with no TV. Just football and sleep, football and sleep."

"I didn’t want a big house. I didn’t want cars. I just wanted to put everything into football. Everything to show the world that my sister was right……."

"Ha…. you will think this is funny. When I moved to play at RB Leipzig, I was always late. Well, not late. But I was on time, which in Germany means you’re very late."

"So you already know what I did next. I started arriving 90 minutes early to everything. I was so early all the time that the guys started calling me “The German.”"

"I always have to overdo everything. I have zero chill. You always said that."

"The pitch is the only place that I feel at home anymore. It’s the place where I feel calm, and I can speak to you. I just wish you were still here so I could tell you….. We did it."

"Everything you said came true."

"We’re leaving for the World Cup tomorrow. For real. Your brother is going to play for Côte d'Ivoire, like Drogba, like Yaya, like Gervinho."

"I don’t even look at it like a game. I look at it like a stage. This is my chance to show the whole world what you saw in me. Every time I score, I’ll make sure everybody knows your name. I’ll make sure they don’t forget you."

"You always said that I could be better than Cristiano. If I see him there, I’ll tell him hello for you."

"I’m going to do what you predicted, I swear. Before I even had real boots, you were telling everybody, “My brother is going to be the greatest in the world.”

"I will prove that you were right, or I will die trying... Your brother, Yan."

[CZ 🔶 BNB @cz_binance]

Saw some people panicking or asking about quantum computing's impact on crypto.
At a high level, all crypto has to do is to upgrade to Quantum-Resistant (Post-Quantum) Algorithms. So, no need to panic. 😂

In practice, there are some execution considerations. It's hard to organize upgrades in a decentralized world. There will likely be many debates on which algorithm(s) to use, resulting in some forks.

And some dead project may not upgrade at all. Might be a good to cleanse out those projects anyway.

New code may introduce other bugs or security issues in the short term.

People who self custody will have to migrate their coins to new wallets.

This brings to the question of Satoshi's bitcoins. If those coins move, then it means he/she is still around, which is interesting to know. If they don't move (in a certain period of time), it might be better to lock (or effectively burn) those addresses so that they don't go to the first hacker who cracks it. There is also the difficulty of identifying all his addresses, and not confuse with some old hodlers. Anyway, it's a different topic for later.

Fundamentally:

It's always easier to encrypt than decrypt.

More computing power is always good.

Crypto will stay, post quantum.

Now, the quantum resistance roadmap.

Today, four things in Ethereum are quantum-vulnerable:

* consensus-layer BLS signatures
* data availability (KZG commitments+proofs)
* EOA signatures (ECDSA)
* Application-layer ZK proofs (KZG or groth16)

We can tackle these step by step:

## Consensus-layer signatures

Lean consensus includes fully replacing BLS signatures with hash-based signatures (some variant of Winternitz), and using STARKs to do aggregation.

Before lean finality, we stand a good chance of getting the Lean available chain. This also involves hash-based signatures, but there are much fewer signatures (eg. 256-1024 per slot), so we do not need STARKs for aggregation.

One important thing upstream of this is choosing the hash function. This may be "Ethereum's last hash function", so it's important to choose wisely. Conventional hashes are too slow, and the most aggressive forms of Poseidon have taken hits on their security analysis recently. Likely options are:

* Poseidon2 plus extra rounds, potentially non-arithmetic layers (eg. Monolith) mixed in
* Poseidon1 (the older version of Poseidon, not vulnerable to any of the recent attacks on Poseidon2, but 2x slower)
* BLAKE3 or similar (take the most efficient conventional hash we know)

## Data availability

Today, we rely pretty heavily on KZG for erasure coding. We could move to STARKs, but this has two problems:

1. If we want to do 2D DAS, then our current setup for this relies on the "linearity" property of KZG commitments; with STARKs we don't have that. However, our current thinking is that it should be sufficient given our scale targets to just max out 1D DAS (ie. PeerDAS). Ethereum is taking a more conservative posture, it's not trying to be a high-scale data layer for the world.
2. We need proofs that erasure coded blobs are correctly constructed. KZG does this "for free". STARKs can substitute, but a STARK is ... bigger than a blob. So you need recursive starks (though there's also alternative techniques, that have their own tradeoffs). This is okay, but the logistics of this get harder if you want to support distributed blob selection.

Summary: it's manageable, but there's a lot of engineering work to do.

## EOA signatures

Here, the answer is clear: we add native AA (see https://t.co/YD9nIpsxcC ), so that we get first-class accounts that can use any signature algorithm.

However, to make this work, we also need quantum-resistant signature algorithms to actually be viable. ECDSA signature verification costs 3000 gas. Quantum-resistant signatures are ... much much larger and heavier to verify.

We know of quantum-resistant hash-based signatures that are in the ~200k gas range to verify.

We also know of lattice-based quantum-resistant signatures. Today, these are extremely inefficient to verify. However, there is work on vectorized math precompiles, that let you perform operations (+, *, %, dot product, also NTT / butterfly permutations) that are at the core of lattice math, and also STARKs. This could greatly reduce the gas cost of lattice-based signatures to a similar range, and potentially go even lower.

The long-term fix is protocol-layer recursive signature and proof aggregation, which could reduce these gas overheads to near-zero.

## Proofs

Today, a ZK-SNARK costs ~300-500k gas. A quantum-resistant STARK is more like 10m gas. The latter is unacceptable for privacy protocols, L2s, and other users of proofs.

The solution again is protocol-layer recursive signature and proof aggregation. So let's talk about what this is.

In EIP-8141, transactions have the ability to include a "validation frame", during which signature verifications and similar operations are supposed to happen. Validation frames cannot access the outside world, they can only look at their calldata and return a value, and nothing else can look at their calldata. This is designed so that it's possible to replace any validation frame (and its calldata) with a STARK that verifies it (potentially a single STARK for all the validation frames in a block).

This way, a block could "contain" a thousand validation frames, each of which contains either a 3 kB signature or even a 256 kB proof, but that 3-256 MB (and the computation needed to verify it) would never come onchain. Instead, it would all get replaced by a proof verifying that the computation is correct.

Potentially, this proving does not even need to be done by the block builder. Instead, I envision that it happens at mempool layer: every 500ms, each node could pass along the new valid transactions that it has seen, along with a proof verifying that they are all valid (including having validation frames that match their stated effects). The overhead is static: only one proof per 500ms. Here's a post where I talk about this:
