What is the blockchain? If you don't know, you should; if you do, chances are you still need some clarification on how it actually works. Don Tapscott is here to help, demystifying this world-changing, trust-building technology which, he says, represents nothing less than the second generation of the internet and holds the potential to transform money, business, government and society.

on the next few decades
1

has arrived.
2
6071
1252
00:19
And it's not social media.
3
7744
2497
00:22
It's not big data.
4
10265
1397
00:23
It's not robotics.
5
11686
1507
00:25
It's not even AI.
6
13217
1483
00:27
You'll be surprised to learn
7
15033
2366
00:29
that it's the underlying technology
of digital currencies like Bitcoin.
of digital currencies like Bitcoin.
8
17423
4712
00:34
It's called the blockchain. Blockchain.
9
22159
3401
00:38
Now, it's not the most sonorous
word in the world,
word in the world,
10
26337
2836
00:42
but I believe that this is now
11
30294
2416
00:44
the next generation of the internet,
12
32734
2541
00:47
and that it holds vast promise
for every business, every society
for every business, every society
13
35299
4575
00:51
and for all of you, individually.
14
39898
1667
00:54
You know, for the past few decades,
we've had the internet of information.
we've had the internet of information.
15
42367
4675
00:59
And when I send you an email
or a PowerPoint file or something,
or a PowerPoint file or something,
16
47066
4221
01:03
I'm actually not sending you the original,
17
51311
2074
01:05
I'm sending you a copy.
18
53409
1363
01:07
And that's great.
19
55222
1517
01:08
This is democratized information.
20
56763
2456
01:12
But when it comes to assets --
21
60441
2758
01:15
things like money,
22
63223
2345
01:17
financial assets like stocks and bonds,
23
65592
2455
01:20
loyalty points, intellectual property,
24
68071
3435
01:23
music, art, a vote,
25
71530
2529
01:26
carbon credit and other assets --
26
74982
2605
01:29
sending you a copy is a really bad idea.
27
77611
2612
01:32
If I send you 100 dollars,
28
80247
1795
01:34
it's really important
that I don't still have the money --
that I don't still have the money --
29
82066
3037
01:37
(Laughter)
30
85127
1007
01:38
and that I can't send it to you.
31
86158
2358
01:40
This has been called
the "double-spend" problem
the "double-spend" problem
32
88540
2337
01:42
by cryptographers for a long time.
33
90901
2094
01:45
So today, we rely entirely
on big intermediaries --
on big intermediaries --
34
93469
5269
01:50
middlemen like banks, government,
35
98762
2253
01:53
big social media companies,
credit card companies and so on --
credit card companies and so on --
36
101039
3564
01:56
to establish trust in our economy.
37
104627
2642
01:59
And these intermediaries perform
all the business and transaction logic
all the business and transaction logic
38
107779
5094
02:04
of every kind of commerce,
39
112897
1396
02:06
from authentication,
identification of people,
identification of people,
40
114317
2661
02:09
through to clearing, settling
and record keeping.
and record keeping.
41
117002
4065
02:13
And overall, they do a pretty good job.
42
121583
1921
02:15
But there are growing problems.
43
123528
1697
02:17
To begin, they're centralized.
44
125942
1532
02:19
That means they can be hacked,
and increasingly are --
and increasingly are --
45
127498
2968
02:22
JP Morgan, the US Federal Government,
46
130490
2559
02:25
LinkedIn, Home Depot and others
47
133073
1791
02:26
found that out the hard way.
48
134888
1415
02:28
They exclude billions of people
from the global economy,
from the global economy,
49
136874
3514
02:32
for example, people
who don't have enough money
who don't have enough money
50
140412
2253
02:34
to have a bank account.
51
142689
1260
02:36
They slow things down.
52
144624
2288
02:38
It can take a second for an email
to go around the world,
to go around the world,
53
146936
3570
02:42
but it can take days or weeks
54
150530
2424
02:44
for money to move through
the banking system across a city.
the banking system across a city.
55
152978
3132
02:48
And they take a big piece of the action --
56
156134
2199
02:50
10 to 20 percent just to send money
to another country.
to another country.
57
158357
3030
02:54
They capture our data,
58
162022
1641
02:55
and that means we can't monetize it
59
163687
1952
02:57
or use it to better manage our lives.
60
165663
2754
03:00
Our privacy is being undermined.
61
168441
2737
03:03
And the biggest problem is that overall,
62
171202
2224
03:06
they've appropriated the largesse
of the digital age asymmetrically:
of the digital age asymmetrically:
63
174005
5881
03:11
we have wealth creation,
but we have growing social inequality.
but we have growing social inequality.
64
179910
4234
03:17
So what if there were not only
an internet of information,
an internet of information,
65
185105
4342
03:21
what if there were an internet of value --
66
189471
2467
03:24
some kind of vast, global,
distributed ledger
distributed ledger
67
192517
4128
03:28
running on millions of computers
68
196669
2138
03:30
and available to everybody.
69
198831
2084
03:32
And where every kind of asset,
from money to music,
from money to music,
70
200939
3851
03:36
could be stored, moved, transacted,
exchanged and managed,
exchanged and managed,
71
204814
5704
03:42
all without powerful intermediaries?
72
210542
2536
03:45
What if there were
a native medium for value?
a native medium for value?
73
213507
3677
03:50
Well, in 2008, the financial
industry crashed
industry crashed
74
218256
4658
03:54
and, perhaps propitiously,
75
222938
2584
03:57
an anonymous person or persons
named Satoshi Nakamoto
named Satoshi Nakamoto
76
225546
4934
04:03
created a paper where he developed
a protocol for a digital cash
a protocol for a digital cash
77
231325
6986
04:10
that used an underlying
cryptocurrency called Bitcoin.
cryptocurrency called Bitcoin.
78
238335
3293
04:14
And this cryptocurrency enabled people
to establish trust and do transactions
to establish trust and do transactions
79
242421
5818
04:20
without a third party.
80
248263
1691
04:21
And this seemingly simple act
set off a spark
set off a spark
81
249978
3736
04:25
that ignited the world,
82
253738
2147
04:27
that has everyone excited
or terrified or otherwise interested
or terrified or otherwise interested
83
255909
5143
04:33
in many places.
84
261076
1245
04:34
Now, don't be confused about Bitcoin --
85
262640
2070
04:36
Bitcoin is an asset; it goes up and down,
86
264734
3175
04:39
and that should be of interest
to you if you're a speculator.
to you if you're a speculator.
87
267933
3012
04:43
More broadly, it's a cryptocurrency.
88
271525
2405
04:45
It's not a fiat currency
controlled by a nation-state.
controlled by a nation-state.
89
273954
3349
04:49
And that's of greater interest.
90
277327
1647
04:51
But the real pony here
is the underlying technology.
is the underlying technology.
91
279412
3214
04:54
It's called blockchain.
92
282650
1831
04:57
So for the first time now
in human history,
in human history,
93
285649
3443
05:01
people everywhere can trust each other
94
289116
2478
05:03
and transact peer to peer.
95
291618
2601
05:07
And trust is established,
not by some big institution,
not by some big institution,
96
295001
4240
05:11
but by collaboration, by cryptography
97
299265
3056
05:14
and by some clever code.
98
302345
2133
05:16
And because trust is native
to the technology,
to the technology,
99
304502
2998
05:20
I call this, "The Trust Protocol."
100
308080
2507
05:22
Now, you're probably wondering:
How does this thing work?
How does this thing work?
101
310896
2754
05:25
Fair enough.
102
313674
1220
05:28
Assets -- digital assets like money
to music and everything in between --
to music and everything in between --
103
316290
5155
05:33
are not stored in a central place,
104
321469
1666
05:35
but they're distributed
across a global ledger,
across a global ledger,
105
323159
2696
05:37
using the highest level of cryptography.
106
325879
2518
05:40
And when a transaction is conducted,
107
328945
2643
05:43
it's posted globally,
108
331612
2078
05:45
across millions and millions of computers.
109
333714
3069
05:49
And out there, around the world,
110
337508
1844
05:51
is a group of people called "miners."
111
339376
2294
05:53
These are not young people,
they're Bitcoin miners.
they're Bitcoin miners.
112
341694
3492
05:57
They have massive computing power
at their fingertips --
at their fingertips --
113
345210
3007
06:00
10 to 100 times bigger
than all of Google worldwide.
than all of Google worldwide.
114
348241
4810
06:05
These miners do a lot of work.
115
353598
1936
06:08
And every 10 minutes,
116
356122
1373
06:09
kind of like the heartbeat of a network,
117
357519
2287
06:11
a block gets created
118
359830
2205
06:14
that has all the transactions
from the previous 10 minutes.
from the previous 10 minutes.
119
362059
3226
06:17
Then the miners get to work,
trying to solve some tough problems.
trying to solve some tough problems.
120
365714
5135
06:22
And they compete:
121
370873
1322
06:24
the first miner to find out the truth
and to validate the block,
and to validate the block,
122
372219
4311
06:28
is rewarded in digital currency,
123
376554
2361
06:30
in the case of the Bitcoin
blockchain, with Bitcoin.
blockchain, with Bitcoin.
124
378939
2763
06:34
And then -- this is the key part --
125
382171
2160
06:36
that block is linked to the previous block
126
384355
2457
06:38
and the previous block
127
386836
1309
06:40
to create a chain of blocks.
128
388169
3248
06:43
And every one is time-stamped,
129
391441
1439
06:44
kind of like with a digital waxed seal.
130
392904
2198
06:47
So if I wanted to go and hack a block
131
395434
2347
06:49
and, say, pay you and you
with the same money,
with the same money,
132
397805
3835
06:54
I'd have to hack that block,
133
402394
1523
06:55
plus all the preceding blocks,
134
403941
1430
06:57
the entire history of commerce
on that blockchain,
on that blockchain,
135
405395
3394
07:00
not just on one computer
but across millions of computers,
but across millions of computers,
136
408813
3491
07:04
simultaneously,
137
412328
1779
07:06
all using the highest
levels of encryption,
levels of encryption,
138
414131
3335
07:09
in the light of the most powerful
computing resource in the world
computing resource in the world
139
417490
3090
07:12
that's watching me.
140
420604
1248
07:13
Tough to do.
141
421876
1165
07:15
This is infinitely more secure
142
423510
2202
07:17
than the computer systems
that we have today.
that we have today.
143
425736
2359
07:20
Blockchain. That's how it works.
144
428119
2584
07:23
So the Bitcoin blockchain is just one.
145
431402
2181
07:25
There are many.
146
433607
1151
07:26
The Ethereum blockchain was developed
by a Canadian named Vitalik Buterin.
by a Canadian named Vitalik Buterin.
147
434782
4894
07:31
He's [22] years old,
148
439700
2230
07:33
and this blockchain
has some extraordinary capabilities.
has some extraordinary capabilities.
149
441954
4218
07:38
One of them is that you can
build smart contracts.
build smart contracts.
150
446196
3083
07:41
It's kind of what it sounds like.
151
449303
1968
07:43
It's a contract that self-executes,
152
451295
2563
07:45
and the contract handles the enforcement,
the management, performance
the management, performance
153
453882
4867
07:50
and payment -- the contract kind of has
a bank account, too, in a sense --
a bank account, too, in a sense --
154
458773
4261
07:55
of agreements between people.
155
463058
2636
07:57
And today, on the Ethereum blockchain,
156
465718
2714
08:00
there are projects underway
to do everything
to do everything
157
468456
2287
08:02
from create a new replacement
for the stock market
for the stock market
158
470767
3162
08:05
to create a new model of democracy,
159
473953
1823
08:07
where politicians
are accountable to citizens.
are accountable to citizens.
160
475800
3103
08:10
(Applause)
161
478927
3460
08:14
So to understand what a radical change
this is going to bring,
this is going to bring,
162
482411
4079
08:18
let's look at one industry,
financial services.
financial services.
163
486514
2293
08:21
Recognize this?
164
489249
1353
08:23
Rube Goldberg machine.
165
491061
1915
08:25
It's a ridiculously complicated machine
that does something really simple,
that does something really simple,
166
493000
3681
08:28
like crack an egg or shut a door.
167
496705
2378
08:31
Well, it kind of reminds me
of the financial services industry,
of the financial services industry,
168
499593
3832
08:35
honestly.
169
503449
1166
08:36
I mean, you tap your card
in the corner store,
in the corner store,
170
504639
2905
08:39
and a bitstream goes through
a dozen companies,
a dozen companies,
171
507568
3251
08:42
each with their own computer system,
172
510843
2363
08:45
some of them being 1970s mainframes
173
513230
2305
08:47
older than many
of the people in this room,
of the people in this room,
174
515559
2792
08:50
and three days later, a settlement occurs.
175
518375
2779
08:53
Well, with a blockchain
financial industry,
financial industry,
176
521740
3524
08:57
there would be no settlement,
177
525288
1403
08:58
because the payment and the settlement
is the same activity,
is the same activity,
178
526715
2858
09:01
it's just a change in the ledger.
179
529597
1744
09:04
So Wall Street and all around the world,
180
532040
2260
09:06
the financial industry
is in a big upheaval about this,
is in a big upheaval about this,
181
534324
3263
09:09
wondering, can we be replaced,
182
537611
2151
09:11
or how do we embrace
this technology for success?
this technology for success?
183
539786
2963
09:15
Now, why should you care?
184
543349
1622
09:18
Well, let me describe some applications.
185
546320
2468
09:21
Prosperity.
186
549748
1668
09:23
The first era of the internet,
187
551440
2008
09:25
the internet of information,
188
553472
1341
09:26
brought us wealth
but not shared prosperity,
but not shared prosperity,
189
554837
3463
09:30
because social inequality is growing.
190
558324
2454
09:32
And this is at the heart
of all of the anger and extremism
of all of the anger and extremism
191
560802
3983
09:36
and protectionism and xenophobia and worse
192
564809
3600
09:40
that we're seeing growing
in the world today,
in the world today,
193
568433
2582
09:43
Brexit being the most recent case.
194
571039
2849
09:46
So could we develop some new approaches
to this problem of inequality?
to this problem of inequality?
195
574868
5743
09:52
Because the only approach today
is to redistribute wealth,
is to redistribute wealth,
196
580635
3749
09:56
tax people and spread it around more.
197
584408
2180
09:58
Could we pre-distribute wealth?
198
586612
2436
10:01
Could we change the way that wealth
gets created in the first place
gets created in the first place
199
589686
3196
10:04
by democratizing wealth creation,
200
592906
2170
10:07
engaging more people in the economy,
201
595100
2393
10:09
and then ensuring that they got
fair compensation?
fair compensation?
202
597517
3096
10:13
Let me describe five ways
that this can be done.
that this can be done.
203
601158
2844
10:16
Number one:
204
604597
1426
10:18
Did you know that 70 percent
of the people in the world who have land
of the people in the world who have land
205
606047
5229
10:23
have a tenuous title to it?
206
611300
2119
10:25
So, you've got a little farm in Honduras,
some dictator comes to power,
some dictator comes to power,
207
613863
3392
10:29
he says, "I know you've got a piece
of paper that says you own your farm,
of paper that says you own your farm,
208
617279
3592
10:32
but the government computer
says my friend owns your farm."
says my friend owns your farm."
209
620895
3655
10:36
This happened on a mass scale in Honduras,
210
624967
2178
10:39
and this problem exists everywhere.
211
627169
2347
10:42
Hernando de Soto, the great
Latin American economist,
Latin American economist,
212
630214
2775
10:45
says this is the number one
issue in the world
issue in the world
213
633013
2144
10:47
in terms of economic mobility,
214
635181
1594
10:48
more important than having a bank account,
215
636799
2141
10:50
because if you don't have
a valid title to your land,
a valid title to your land,
216
638964
2633
10:53
you can't borrow against it,
217
641621
1556
10:55
and you can't plan for the future.
218
643201
2022
10:57
So today, companies
are working with governments
are working with governments
219
645969
3340
11:01
to put land titles on a blockchain.
220
649333
2443
11:03
And once it's there, this is immutable.
221
651800
2300
11:06
You can't hack it.
222
654718
1246
11:08
This creates the conditions for prosperity
223
656313
3155
11:11
for potentially billions of people.
224
659492
2168
11:14
Secondly:
225
662505
1163
11:16
a lot of writers talk about Uber
226
664295
2234
11:18
and Airbnb and TaskRabbit
and Lyft and so on
and Lyft and so on
227
666553
3335
11:21
as part of the sharing economy.
228
669912
2296
11:24
This is a very powerful idea,
229
672232
1664
11:25
that peers can come together
and create and share wealth.
and create and share wealth.
230
673920
3179
11:29
My view is that ...
231
677710
1413
11:31
these companies are not really sharing.
232
679729
3995
11:35
In fact, they're successful
precisely because they don't share.
precisely because they don't share.
233
683748
4107
11:39
They aggregate services together,
and they sell them.
and they sell them.
234
687879
3172
11:43
What if, rather than Airbnb
being a $25 billion corporation,
being a $25 billion corporation,
235
691710
4932
11:48
there was a distributed application
on a blockchain, we'll call it B-Airbnb,
on a blockchain, we'll call it B-Airbnb,
236
696666
5506
11:54
and it was essentially owned
by all of the people
by all of the people
237
702196
4034
11:58
who have a room to rent.
238
706254
1732
12:00
And when someone wants to rent a room,
239
708574
2571
12:03
they go onto the blockchain
database and all the criteria,
database and all the criteria,
240
711169
4142
12:07
they sift through, it helps
them find the right room,
them find the right room,
241
715335
2507
12:09
and then the blockchain helps
with the contracting,
with the contracting,
242
717866
2769
12:12
it identifies the party,
243
720659
1872
12:14
it handles the payments
244
722555
1358
12:15
just through digital payments --
they're built into the system.
they're built into the system.
245
723937
3246
12:19
And it even handles reputation,
246
727207
1531
12:20
because if she rates a room
as a five-star room,
as a five-star room,
247
728762
4192
12:24
that room is there,
248
732978
1216
12:26
and it's rated, and it's immutable.
249
734218
2227
12:29
So, the big sharing-economy
disruptors in Silicon Valley
disruptors in Silicon Valley
250
737043
4744
12:34
could be disrupted,
251
742542
1157
12:36
and this would be good for prosperity.
252
744096
2241
12:38
Number three:
253
746361
1157
12:40
the biggest flow of funds
from the developed world
from the developed world
254
748403
2571
12:42
to the developing world
255
750998
1286
12:44
is not corporate investment,
256
752308
2262
12:46
and it's not even foreign aid.
257
754594
2281
12:49
It's remittances.
258
757605
2000
12:52
This is the global diaspora;
259
760329
1935
12:54
people have left their ancestral lands,
260
762288
2357
12:56
and they're sending money back
to their families at home.
to their families at home.
261
764669
3889
13:00
This is 600 billion dollars a year,
and it's growing,
and it's growing,
262
768582
3123
13:03
and these people are getting ripped off.
263
771729
2040
13:06
AnnaLee Domingo is a housekeeper.
264
774555
2614
13:09
She lives in Toronto,
265
777864
1905
13:11
and every month she goes
to the Western Union office
to the Western Union office
266
779793
4764
13:16
with some cash
267
784581
1539
13:18
to send her remittances
to her mom in Manila.
to her mom in Manila.
268
786144
2960
13:21
It costs her around 10 percent;
269
789835
1893
13:23
the money takes four to seven
days to get there;
days to get there;
270
791752
2240
13:26
her mom never knows
when it's going to arrive.
when it's going to arrive.
271
794016
2164
13:28
It takes five hours
out of her week to do this.
out of her week to do this.
272
796204
2534
13:31
Six months ago,
273
799571
1152
13:32
AnnaLee Domingo used
a blockchain application called Abra.
a blockchain application called Abra.
274
800747
4580
13:37
And from her mobile device,
she sent 300 bucks.
she sent 300 bucks.
275
805771
2613
13:40
It went directly
to her mom's mobile device
to her mom's mobile device
276
808408
2480
13:42
without going through an intermediary.
277
810912
1884
13:45
And then her mom
looked at her mobile device --
looked at her mobile device --
278
813346
2392
13:47
it's kind of like an Uber interface,
there's Abra "tellers" moving around.
there's Abra "tellers" moving around.
279
815762
3789
13:51
She clicks on a teller
that's a five-star teller,
that's a five-star teller,
280
819575
2738
13:54
who's seven minutes away.
281
822337
1385
13:56
The guy shows up at the door,
gives her Filipino pesos,
gives her Filipino pesos,
282
824266
3080
13:59
she puts them in her wallet.
283
827370
1566
14:01
The whole thing took minutes,
284
829365
1756
14:03
and it cost her two percent.
285
831145
1863
14:06
This is a big opportunity for prosperity.
286
834269
2851
14:09
Number four: the most powerful asset
of the digital age is data.
of the digital age is data.
287
837637
4219
14:14
And data is really a new asset class,
288
842279
3663
14:17
maybe bigger than previous asset classes,
289
845966
2279
14:20
like land under the agrarian economy,
290
848269
2961
14:23
or an industrial plant,
291
851254
1653
14:24
or even money.
292
852931
1157
14:26
And all of you -- we -- create this data.
293
854540
3010
14:29
We create this asset,
294
857574
1782
14:31
and we leave this trail
of digital crumbs behind us
of digital crumbs behind us
295
859380
2715
14:34
as we go throughout life.
296
862119
1830
14:35
And these crumbs are collected
into a mirror image of you,
into a mirror image of you,
297
863973
2820
14:38
the virtual you.
298
866817
1224
14:40
And the virtual you may know
more about you than you do,
more about you than you do,
299
868481
2671
14:43
because you can't remember
what you bought a year ago,
what you bought a year ago,
300
871176
2631
14:45
or said a year ago,
or your exact location a year ago.
or your exact location a year ago.
301
873831
2639
14:48
And the virtual you is not owned by you --
302
876494
2777
14:51
that's the big problem.
303
879295
1467
14:53
So today, there are companies working
304
881419
2578
14:56
to create an identity in a black box,
305
884021
3637
14:59
the virtual you owned by you.
306
887682
1611
15:01
And this black box moves around with you
307
889853
3305
15:05
as you travel throughout the world,
308
893182
1990
15:07
and it's very, very stingy.
309
895196
2070
15:09
It only gives away
the shred of information
the shred of information
310
897290
3055
15:12
that's required to do something.
311
900369
1547
15:13
A lot of transactions,
312
901940
1289
15:15
the seller doesn't even need
to know who you are.
to know who you are.
313
903253
2473
15:17
They just need to know that they got paid.
314
905750
2468
15:20
And then this avatar
is sweeping up all of this data
is sweeping up all of this data
315
908741
3949
15:24
and enabling you to monetize it.
316
912714
2744
15:28
And this is a wonderful thing,
317
916061
1788
15:29
because it can also help us
protect our privacy,
protect our privacy,
318
917873
3191
15:33
and privacy is the foundation
of a free society.
of a free society.
319
921088
3812
15:36
Let's get this asset that we create
320
924924
1966
15:38
back under our control,
321
926914
1777
15:40
where we can own our own identity
322
928715
2008
15:42
and manage it responsibly.
323
930747
1771
15:45
Finally --
324
933817
1157
15:46
(Applause)
325
934998
4798
15:52
Finally, number five:
326
940335
1496
15:53
there are a whole number
of creators of content
of creators of content
327
941855
3262
15:57
who don't receive fair compensation,
328
945141
2207
15:59
because the system
for intellectual property is broken.
for intellectual property is broken.
329
947372
3092
16:02
It was broken by the first era
of the internet.
of the internet.
330
950488
3112
16:05
Take music.
331
953624
1467
16:07
Musicians are left with crumbs
at the end of the whole food chain.
at the end of the whole food chain.
332
955734
3130
16:10
You know, if you were a songwriter,
25 years ago, you wrote a hit song,
25 years ago, you wrote a hit song,
333
958888
4840
16:15
it got a million singles,
334
963752
2262
16:18
you could get royalties
of around 45,000 dollars.
of around 45,000 dollars.
335
966038
3521
16:21
Today, you're a songwriter,
you write a hit song,
you write a hit song,
336
969583
2316
16:23
it gets a million streams,
337
971923
1453
16:25
you don't get 45k,
338
973400
1770
16:27
you get 36 dollars,
339
975194
2587
16:29
enough to buy a nice pizza.
340
977805
1947
16:32
So Imogen Heap,
341
980721
1378
16:34
the Grammy-winning singer-songwriter,
342
982123
2384
16:36
is now putting music
on a blockchain ecosystem.
on a blockchain ecosystem.
343
984531
3971
16:40
She calls it "Mycelia."
344
988526
1849
16:42
And the music has
a smart contract surrounding it.
a smart contract surrounding it.
345
990399
4106
16:46
And the music protects
her intellectual property rights.
her intellectual property rights.
346
994529
3523
16:50
You want to listen to the song?
347
998076
1513
16:51
It's free, or maybe a few micro-cents
that flow into a digital account.
that flow into a digital account.
348
999613
3357
16:54
You want to put the song
in your movie, that's different,
in your movie, that's different,
349
1002994
2698
16:57
and the IP rights are all specified.
350
1005716
1759
16:59
You want to make a ringtone?
That's different.
That's different.
351
1007499
2263
17:02
She describes that the song
becomes a business.
becomes a business.
352
1010230
3209
17:05
It's out there on this platform
marketing itself,
marketing itself,
353
1013463
2809
17:08
protecting the rights of the author,
354
1016296
1967
17:10
and because the song has a payment system
355
1018287
2155
17:12
in the sense of bank account,
356
1020466
1462
17:13
all the money flows back to the artist,
357
1021952
2348
17:16
and they control the industry,
358
1024324
2235
17:18
rather than these powerful intermediaries.
359
1026583
2412
17:21
Now, this is --
360
1029757
1151
17:22
(Applause)
361
1030932
