@TrinityWinujnf 雨続きでモチベーション下がるのはすごくわかる！私も天気のせいで撮りたかった景色が撮れなかった経験あるから、明日は晴れて欲しいな😔

[俊明😟 @SAustin18366]

@EllaChipsy1 朝から疲れるね😞

[俊明😟 @SAustin18366]

@IslaDickwje3 夏の早起きは苦手だけど、休日の朝はなぜかすっきり起きれるから不思議。

[俊明😟 @SAustin18366]

朝7時、日曜の早起きが癖になってて眠れない。暑いから目が覚めるんだよな。

[俊明😟 @SAustin18366]

@AdaMajororal 本当！朝ランニングは目覚めがいいし、日中の活動も活発になる！

[俊明��� @SAustin18366]

最近は朝のランニングを習慣化してて、涼しい朝の空気を吸いながら名古屋の街を走るのは最高に気持いい。

土日は一日中店の仕事して疲れる。平日は平和に過ごせて良かったと思ってたけど、休みの日が休みじゃなくなってきて本音はとてもストレス溜まってる

[俊明😟 @SAustin18366]

最近やけに体が重くて、朝起きるの辛いな。自営業って思ってる以上に体力消耗するし、夏の暑さでさらにバテてる。水分とって、軽くストレッチでもして改善するか

🧵 Why is everyone talking about @op_catlayer ?

Many people have heard the name.

But very few understand why OP_CAT matters to Bitcoin.

Let's break it down.👇

1/ What exactly is OP_CAT?

OP_CAT is one of Bitcoin's original opcodes.

Its job is surprisingly simple:

It concatenates (joins) two pieces of data together.

That sounds trivial…

Until you realize this small capability enables developers to construct far more expressive verification logic directly on Bitcoin.

Sometimes, one small opcode unlocks an entirely new design space.

2/ Why was it removed?

In Bitcoin's early years, OP_CAT was disabled alongside several other opcodes due to security concerns.

At the time:

• Bitcoin had very few users.
• Script analysis was immature.
• Simplicity was considered the safest choice.
Removing OP_CAT reduced the attack surface.
But Bitcoin has evolved dramatically since then.

3/ Why are people discussing it again?

Because Bitcoin is no longer just digital gold.

Today, developers want to build:

• BTCFi
• Decentralized exchanges
• Stablecoins
• Cross-chain bridges
• AI-native applications
• On-chain identity
• Native social networks
• Programmable digital assets

Bitcoin has become the world's most secure settlement layer.

Now builders want more expressive programmability—without changing Bitcoin's fundamental security model.
That's where OP_CAT enters the conversation.
4/ What can OP_CAT actually enable?
On its own?
Not much.
Combined with Bitcoin Script?
A lot.
Researchers have shown that OP_CAT can enable or significantly simplify:

✅ More expressive covenant constructions

✅ Better verification logic

✅ Advanced UTXO applications

✅ Efficient state transitions

✅ Trust-minimized protocols

In other words…

It expands what Bitcoin developers can build natively.

5/ Does OP_CAT turn Bitcoin into Ethereum?

No.

This is probably the biggest misconception.

OP_CAT doesn't introduce:

❌ Solidity

❌ EVM

❌ Account model

❌ Gas-based smart contracts

Bitcoin remains Bitcoin.

It simply gains additional scripting expressiveness while keeping the UTXO model intact.

6/ Why are so many teams paying attention?

Because OP_CAT could unlock an entire Bitcoin-native ecosystem.

Projects are already researching or building around:

• BTCFi
• Native execution layers
• Cross-chain infrastructure
• Wallets
• Asset protocols
• AI applications
• On-chain social
• Zero-knowledge integrations

Everyone sees the same opportunity:

Build directly on Bitcoin.

7/ Why does this matter?

For years, Bitcoin has been incredibly secure…

…but relatively difficult to build on.

OP_CAT narrows that gap.

It gives developers more tools while preserving Bitcoin's core principles:

✔ Decentralization

✔ Security
✔ Permissionless innovation
More capabilities.
Without abandoning Bitcoin's identity.
8/ What happens next?
OP_CAT is currently an active proposal under discussion within the Bitcoin community.
Whether or not it is eventually activated will depend on continued technical review, community consensus, implementation work, and the broader Bitcoin upgrade process.
Regardless of the outcome, one thing is already clear:

The conversation has changed.

Builders are no longer asking "Can Bitcoin support native applications?"

They're asking:

"What should we build on Bitcoin next?"

9/ Final Thoughts

The future of Bitcoin won't be defined by one application.

It will be defined by the infrastructure that enables thousands of applications.

OP_CAT isn't about changing Bitcoin.

It's about expanding what's possible—while staying true to Bitcoin's design philosophy.

The next chapter of Bitcoin may not be about bigger blocks.

It may be about bigger possibilities.
