1
00:00:08,000 --> 00:00:11,700
Anyone can paste AI text
and call it their own.

2
00:00:11,700 --> 00:00:15,300
Near The Keyboard lets
you prove you typed it.

3
00:00:15,300 --> 00:00:19,400
Log in with your NEAR account.

4
00:00:19,400 --> 00:00:23,200
Your wallet adds a key
that can only talk to NTK.

5
00:00:23,200 --> 00:00:31,100
Then type three short texts,
so NTK learns how you type.

6
00:00:31,100 --> 00:00:33,800
Fingerprint created,
sealed in the enclave.

7
00:00:33,800 --> 00:00:40,100
NTK measures each tap: the hold, the move
to the next key, where your finger lands.

8
00:00:40,100 --> 00:00:44,700
The measurements are sealed on the phone.
Only the enclave can open them.

9
00:00:44,700 --> 00:00:48,900
It runs on OutLayer, in Intel TDX.
NEAR records which code may use its keys.

10
00:00:48,900 --> 00:00:52,900
Inside, they become
your typing fingerprint.

11
00:00:52,900 --> 00:00:56,200
Nobody can read it: not us,
not OutLayer, not you.

12
00:00:56,200 --> 00:01:01,000
You answer Maya with the NTK keyboard.

13
00:01:01,000 --> 00:01:06,000
Type as usual, then tap Sign.

14
00:01:06,000 --> 00:01:09,700
The typing goes sealed to
the enclave for a check.

15
00:01:09,700 --> 00:01:13,700
It matches: the keyboard adds the tag.

16
00:01:13,700 --> 00:01:15,200
Send.

17
00:01:15,200 --> 00:01:18,700
Sign sends the new typing,
sealed, to the enclave.

18
00:01:18,700 --> 00:01:22,700
NEAR confirms that the key
belongs to your account.

19
00:01:22,700 --> 00:01:27,900
The enclave compares the new
typing with your fingerprint.

20
00:01:27,900 --> 00:01:31,900
Only the enclave’s key can sign the stamp.

21
00:01:31,900 --> 00:01:35,300
The tag goes into your text.
The stamp is published.

22
00:01:35,300 --> 00:01:38,600
Anyone can look it up by its id.

23
00:01:38,600 --> 00:01:50,000
On Maya’s phone, NTK turns the
tag into a button. In any app.

24
00:01:50,000 --> 00:01:53,500
Maya taps it.

25
00:01:53,500 --> 00:01:59,000
MATCH: the stamp is genuine
and the text unchanged.

26
00:01:59,000 --> 00:02:11,600
Anyone can check it.
Change one word and it fails.
