The upcoming week will be important on #Bitcoin.

It will mark the point where the markets are breaking above the 200-Week MA again.

If it does, I imagine the price to accelerate to $70,000 in a fast way.

Скоро будет 24 февраля — 4 года полномасштабного вторжения в Украину.

Я считаю, что лучше оставить тот день для полной поддержки украинцев. Украине нужно много помощи — чтобы продолжать защищаться и чтобы минимизировать человеческие страдания от атак на жилые дома, энергосистему и т. д. Сегодня выскажу своё мнение с точки зрения будущего России.

Я смотрю на эту ситуацию частично с внутренней и частично с внешней перспективы. Я родился в России, моя семья вся русская, но вырос я в Канаде. Политическую ситуацию я всё время наблюдал. В 2017 году даже послал Навальному один биткоин, но сильно вовлечён не был. Я слежу за ситуацией через интернет, как все. И у меня есть свои политические инстинкты после 15 лет в крипте и всякой борьбы в Твиттере (Иксе?). У каждого есть право меня слушать или не слушать — как хотите.

Здесь напишу две части:

1. Почему я поддерживаю Украину и говорю, что эта война — преступная агрессия, а не «сложная ситуация, где обе стороны вели себя грязно», как говорят некоторые?
2. Про будущее: сегодняшний «тупик», идея «мира с народом России», и на основе каких идей может быть создано более положительное будущее России, и правильная роль идей «децентрализации», «цифровой демократии» и.т.д.

Bull markets have lasted 5x longer than bear markets on average.

Bulls: +254% over 5 years 🐂
Bears: –31% over 1 year🐻

Markets spend far more time growing wealth than destroying it. Why interrupting compounding is the biggest risk of all.

1/ Fusaka is coming December 3rd.

Ethereum’s next major upgrade shows that the network can grow to meet global demand, without compromising on decentralization or permissionlessness.

Whether you’re a user, builder, institution, or operator, here’s how Fusaka will impact you.

[Zun @Zun2025]

Ethereum Fusaka upgrade will go live this week and here is what will change in the upgrade :

1. PeerDAS (Peer Data Availability Sampling) : EIP-7594

so before explaining this, you must need to know about blobs. so think of blobs as temporary storage lockers for L2 networks.

when we use dapps on Arbitrum, Optimism or other Layer 2s, our tx data needs to be posted to Ethereum for security, blobs are special containers designed exactly for this data to store temporarily.

Before Blobs (Pre-Dencun) :
▫️L2 Transaction Data stored in calldata
▫️Cost : $$$$ (Expensive, Stored forever)
▫️L2 fees : $1-10+ per tx during congestion

After Blobs (Post-Dencun) :
▫️L2 Transaction Data stored in BLOBS
▫️Cost: $ (Cheap, Temporary storage)
▫️L2 fees : $0.001-0.10 per tx

So, in DAS, Instead of downloading all blob data to verify it exists, nodes sample small random pieces.

If enough random samples check out, the full data is statistically guaranteed to be available.

-----> Analogy :

Let's say you want to check pizza quality of any shop, here is what happens with and without DAS

Old Way (Download Everything) :
▫️Eat the entire pizza to verify quality
▫️Time : Long
▫️Stomach : Full
▫️Cost : Expensive

New Way (Sampling) :
▫️Take 5 random bites from different slices
▫️If all 5 are good → Pizza is probably good
▫️Time : Quick
▫️Stomach : Room for more
▫️Cost : Cheap

-----> In Blockchan terms :

Before Fusaka :
▫️ Every full node must store all blob data from L2s
▫️ Storage : 100% of blob data
▫️ Bandwidth : high (downloads everything)

After Fusaka :
▫️ Each node stores only 1/8th of the blob data
▫️ Full blob data can be reconstructed from any 50% of the network node
▫️ Bandwidth : ~80% reduction

Impact : 8x theoretical scaling without increasing node requirements

2. Gas Limit Increase to 60 Million : EIP-7935

have u ever noticed that some blocks contain 150 txs , some block contains 400 txs?

this is because of the block gas limit, each block has max cap of gas limit, if there is any txs with less gas limit, then u will see many txs in that block.

on the other hand if there are tx with more gas usage, in that case, you will see less txs in that block.

Before Fusaka :
▫️ Block Capacity : 45 Million Gas
▫️ Transactions : ~1,500 simple transfers
▫️ Congestion : Common during high activity

After Fusaka :
▫️ Block Capacity : 60 Million Gas
▫️ Transactions : ~2,000 simple transfers (+33%)
▫️ Congestion : Reduced

3. Transaction Gas Limit Cap : EIP-7825

Fusaka introduced gas limit cap per tx to prevent DoS attack.

Before Fusaka :
▫️ Single Transaction Could Consume entire Block's 45M Gas, for example this tx : https://t.co/aATMpVE8vL used all the entire block gas and thus there were no other tx in that block : https://t.co/M8fZVLUAva
▫️Risk : DoS attacks possible

After Fusaka :
▫️ Maximum 16.7M Gas Per Transaction (2²⁴)
▫️ DoS protection enabled
▫️ ~3.5+ large transactions per block minimum

4. secp256r1 Curve Support : EIP-7951 (Precompile)

This upgrade also introduce native mobile hardware security.

Before Fusaka :
▫️ Signing method : Only secp256k1 (Bitcoin/Ethereum)
▫️ No native mobile secure enclave
▫️ Hardware wallets need special chips

After Fusaka :
▫️ Signing Methods : secp256k1 (Original) + secp256r1 (New)
▫️ iPhone Secure Enclave supported
▫️ Android Hardware Security Module supported
▫️ FIDO2/WebAuthn compatibility
▫️ Hardware-backed mobile wallets
