The technology likely to have the greatest impact
0
12831
3446
00:16
on the next few decades
1
16301
1746
00:18
has arrived.
2
18071
1252
00:19
And it's not social media.
3
19744
2497
00:22
It's not big data.
4
22265
1397
00:23
It's not robotics.
5
23686
1507
00:25
It's not even AI.
6
25217
1483
00:27
You'll be surprised to learn
7
27033
2366
00:29
that it's the underlying technology of digital currencies like Bitcoin.
8
29423
4712
00:34
It's called the blockchain. Blockchain.
9
34159
3401
00:38
Now, it's not the most sonorous word in the world,
10
38337
2836
00:42
but I believe that this is now
11
42294
2416
00:44
the next generation of the internet,
12
44734
2541
00:47
and that it holds vast promise for every business, every society
13
47299
4575
00:51
and for all of you, individually.
14
51898
1667
00:54
You know, for the past few decades, we've had the internet of information.
15
54367
4675
00:59
And when I send you an email or a PowerPoint file or something,
16
59066
4221
01:03
I'm actually not sending you the original,
17
63311
2074
01:05
I'm sending you a copy.
18
65409
1363
01:07
And that's great.
19
67222
1517
01:08
This is democratized information.
20
68763
2456
01:12
But when it comes to assets --
21
72441
2758
01:15
things like money,
22
75223
2345
01:17
financial assets like stocks and bonds,
23
77592
2455
01:20
loyalty points, intellectual property,
24
80071
3435
01:23
music, art, a vote,
25
83530
2529
01:26
carbon credit and other assets --
26
86982
2605
01:29
sending you a copy is a really bad idea.
27
89611
2612
01:32
If I send you 100 dollars,
28
92247
1795
01:34
it's really important that I don't still have the money --
29
94066
3037
01:37
(Laughter)
30
97127
1007
01:38
and that I can't send it to you.
31
98158
2358
01:40
This has been called the "double-spend" problem
32
100540
2337
01:42
by cryptographers for a long time.
33
102901
2094
01:45
So today, we rely entirely on big intermediaries --
34
105469
5269
01:50
middlemen like banks, government,
35
110762
2253
01:53
big social media companies, credit card companies and so on --
36
113039
3564
01:56
to establish trust in our economy.
37
116627
2642
01:59
And these intermediaries perform all the business and transaction logic
38
119779
5094
02:04
of every kind of commerce,
39
124897
1396
02:06
from authentication, identification of people,
40
126317
2661
02:09
through to clearing, settling and record keeping.
41
129002
4065
02:13
And overall, they do a pretty good job.
42
133583
1921
02:15
But there are growing problems.
43
135528
1697
02:17
To begin, they're centralized.
44
137942
1532
02:19
That means they can be hacked, and increasingly are --
45
139498
2968
02:22
JP Morgan, the US Federal Government,
46
142490
2559
02:25
LinkedIn, Home Depot and others
47
145073
1791
02:26
found that out the hard way.
48
146888
1415
02:28
They exclude billions of people from the global economy,
49
148874
3514
02:32
for example, people who don't have enough money
50
152412
2253
02:34
to have a bank account.
51
154689
1260
02:36
They slow things down.
52
156624
2288
02:38
It can take a second for an email to go around the world,
53
158936
3570
02:42
but it can take days or weeks
54
162530
2424
02:44
for money to move through the banking system across a city.
55
164978
3132
02:48
And they take a big piece of the action --
56
168134
2199
02:50
10 to 20 percent just to send money to another country.
57
170357
3030
02:54
They capture our data,
58
174022
1641
02:55
and that means we can't monetize it
59
175687
1952
02:57
or use it to better manage our lives.
60
177663
2754
03:00
Our privacy is being undermined.
61
180441
2737
03:03
And the biggest problem is that overall,
62
183202
2224
03:06
they've appropriated the largesse of the digital age asymmetrically:
63
186005
5881
03:11
we have wealth creation, but we have growing social inequality.
64
191910
4234
03:17
So what if there were not only an internet of information,
65
197105
4342
03:21
what if there were an internet of value --
66
201471
2467
03:24
some kind of vast, global, distributed ledger
67
204517
4128
03:28
running on millions of computers
68
208669
2138
03:30
and available to everybody.
69
210831
2084
03:32
And where every kind of asset, from money to music,
70
212939
3851
03:36
could be stored, moved, transacted, exchanged and managed,
71
216814
5704
03:42
all without powerful intermediaries?
72
222542
2536
03:45
What if there were a native medium for value?
73
225507
3677
03:50
Well, in 2008, the financial industry crashed
74
230256
4658
03:54
and, perhaps propitiously,
75
234938
2584
03:57
an anonymous person or persons named Satoshi Nakamoto
76
237546
4934
04:03
created a paper where he developed a protocol for a digital cash
77
243325
6986
04:10
that used an underlying cryptocurrency called Bitcoin.
78
250335
3293
04:14
And this cryptocurrency enabled people to establish trust and do transactions
79
254421
5818
04:20
without a third party.
80
260263
1691
04:21
And this seemingly simple act set off a spark
81
261978
3736
04:25
that ignited the world,
82
265738
2147
04:27
that has everyone excited or terrified or otherwise interested
83
267909
5143
04:33
in many places.
84
273076
1245
04:34
Now, don't be confused about Bitcoin --
85
274640
2070
04:36
Bitcoin is an asset; it goes up and down,
86
276734
3175
04:39
and that should be of interest to you if you're a speculator.
87
279933
3012
04:43
More broadly, it's a cryptocurrency.
88
283525
2405
04:45
It's not a fiat currency controlled by a nation-state.
89
285954
3349
04:49
And that's of greater interest.
90
289327
1647
04:51
But the real pony here is the underlying technology.
91
291412
3214
04:54
It's called blockchain.
92
294650
1831
04:57
So for the first time now in human history,
93
297649
3443
05:01
people everywhere can trust each other
94
301116
2478
05:03
and transact peer to peer.
95
303618
2601
05:07
And trust is established, not by some big institution,
96
307001
4240
05:11
but by collaboration, by cryptography
97
311265
3056
05:14
and by some clever code.
98
314345
2133
05:16
And because trust is native to the technology,
99
316502
2998
05:20
I call this, "The Trust Protocol."
100
320080
2507
05:22
Now, you're probably wondering: How does this thing work?
101
322896
2754
05:25
Fair enough.
102
325674
1220
05:28
Assets -- digital assets like money to music and everything in between --
103
328290
5155
05:33
are not stored in a central place,
104
333469
1666
05:35
but they're distributed across a global ledger,
105
335159
2696
05:37
using the highest level of cryptography.
106
337879
2518
05:40
And when a transaction is conducted,
107
340945
2643
05:43
it's posted globally,
108
343612
2078
05:45
across millions and millions of computers.
109
345714
3069
05:49
And out there, around the world,
110
349508
1844
05:51
is a group of people called "miners."
111
351376
2294
05:53
These are not young people, they're Bitcoin miners.
112
353694
3492
05:57
They have massive computing power at their fingertips --
113
357210
3007
06:00
10 to 100 times bigger than all of Google worldwide.
114
360241
4810
06:05
These miners do a lot of work.
115
365598
1936
06:08
And every 10 minutes,
116
368122
1373
06:09
kind of like the heartbeat of a network,
117
369519
2287
06:11
a block gets created
118
371830
2205
06:14
that has all the transactions from the previous 10 minutes.
119
374059
3226
06:17
Then the miners get to work, trying to solve some tough problems.
120
377714
5135
06:22
And they compete:
121
382873
1322
06:24
the first miner to find out the truth and to validate the block,
122
384219
4311
06:28
is rewarded in digital currency,
123
388554
2361
06:30
in the case of the Bitcoin blockchain, with Bitcoin.
124
390939
2763
06:34
And then -- this is the key part --
125
394171
2160
06:36
that block is linked to the previous block
126
396355
2457
06:38
and the previous block
127
398836
1309
06:40
to create a chain of blocks.
128
400169
3248
06:43
And every one is time-stamped,
129
403441
1439
06:44
kind of like with a digital waxed seal.
130
404904
2198
06:47
So if I wanted to go and hack a block
131
407434
2347
06:49
and, say, pay you and you with the same money,
132
409805
3835
06:54
I'd have to hack that block,
133
414394
1523
06:55
plus all the preceding blocks,
134
415941
1430
06:57
the entire history of commerce on that blockchain,
135
417395
3394
07:00
not just on one computer but across millions of computers,
136
420813
3491
07:04
simultaneously,
137
424328
1779
07:06
all using the highest levels of encryption,
138
426131
3335
07:09
in the light of the most powerful computing resource in the world
139
429490
3090
07:12
that's watching me.
140
432604
1248
07:13
Tough to do.
141
433876
1165
07:15
This is infinitely more secure
142
435510
2202
07:17
than the computer systems that we have today.
143
437736
2359
07:20
Blockchain. That's how it works.
144
440119
2584
07:23
So the Bitcoin blockchain is just one.
145
443402
2181
07:25
There are many.
146
445607
1151
07:26
The Ethereum blockchain was developed by a Canadian named Vitalik Buterin.
147
446782
4894
07:31
He's [22] years old,
148
451700
2230
07:33
and this blockchain has some extraordinary capabilities.
149
453954
4218
07:38
One of them is that you can build smart contracts.
150
458196
3083
07:41
It's kind of what it sounds like.
151
461303
1968
07:43
It's a contract that self-executes,
152
463295
2563
07:45
and the contract handles the enforcement, the management, performance
153
465882
4867
07:50
and payment -- the contract kind of has a bank account, too, in a sense --
154
470773
4261
07:55
of agreements between people.
155
475058
2636
07:57
And today, on the Ethereum blockchain,
156
477718
2714
08:00
there are projects underway to do everything
157
480456
2287
08:02
from create a new replacement for the stock market
158
482767
3162
08:05
to create a new model of democracy,
159
485953
1823
08:07
where politicians are accountable to citizens.
160
487800
3103
08:10
(Applause)
161
490927
3460
08:14
So to understand what a radical change this is going to bring,
162
494411
4079
08:18
let's look at one industry, financial services.
163
498514
2293
08:21
Recognize this?
164
501249
1353
08:23
Rube Goldberg machine.
165
503061
1915
08:25
It's a ridiculously complicated machine that does something really simple,
166
505000
3681
08:28
like crack an egg or shut a door.
167
508705
2378
08:31
Well, it kind of reminds me of the financial services industry,
168
511593
3832
08:35
honestly.
169
515449
1166
08:36
I mean, you tap your card in the corner store,
170
516639
2905
08:39
and a bitstream goes through a dozen companies,
171
519568
3251
08:42
each with their own computer system,
172
522843
2363
08:45
some of them being 1970s mainframes
173
525230
2305
08:47
older than many of the people in this room,
174
527559
2792
08:50
and three days later, a settlement occurs.
175
530375
2779
08:53
Well, with a blockchain financial industry,
176
533740
3524
08:57
there would be no settlement,
177
537288
1403
08:58
because the payment and the settlement is the same activity,
178
538715
2858
09:01
it's just a change in the ledger.
179
541597
1744
09:04
So Wall Street and all around the world,
180
544040
2260
09:06
the financial industry is in a big upheaval about this,
181
546324
3263
09:09
wondering, can we be replaced,
182
549611
2151
09:11
or how do we embrace this technology for success?
183
551786
2963
09:15
Now, why should you care?
184
555349
1622
09:18
Well, let me describe some applications.
185
558320
2468
09:21
Prosperity.
186
561748
1668
09:23
The first era of the internet,
187
563440
2008
09:25
the internet of information,
188
565472
1341
09:26
brought us wealth but not shared prosperity,
189
566837
3463
09:30
because social inequality is growing.
190
570324
2454
09:32
And this is at the heart of all of the anger and extremism
191
572802
3983
09:36
and protectionism and xenophobia and worse
192
576809
3600
09:40
that we're seeing growing in the world today,
193
580433
2582
09:43
Brexit being the most recent case.
194
583039
2849
09:46
So could we develop some new approaches to this problem of inequality?
195
586868
5743
09:52
Because the only approach today is to redistribute wealth,
196
592635
3749
09:56
tax people and spread it around more.
197
596408
2180
09:58
Could we pre-distribute wealth?
198
598612
2436
10:01
Could we change the way that wealth gets created in the first place
199
601686
3196
10:04
by democratizing wealth creation,
200
604906
2170
10:07
engaging more people in the economy,
201
607100
2393
10:09
and then ensuring that they got fair compensation?
202
609517
3096
10:13
Let me describe five ways that this can be done.
203
613158
2844
10:16
Number one:
204
616597
1426
10:18
Did you know that 70 percent of the people in the world who have land
205
618047
5229
10:23
have a tenuous title to it?
206
623300
2119
10:25
So, you've got a little farm in Honduras, some dictator comes to power,
207
625863
3392
10:29
he says, "I know you've got a piece of paper that says you own your farm,
208
629279
3592
10:32
but the government computer says my friend owns your farm."
209
632895
3655
10:36
This happened on a mass scale in Honduras,
210
636967
2178
10:39
and this problem exists everywhere.
211
639169
2347
10:42
Hernando de Soto, the great Latin American economist,
212
642214
2775
10:45
says this is the number one issue in the world
213
645013
2144
10:47
in terms of economic mobility,
214
647181
1594
10:48
more important than having a bank account,
215
648799
2141
10:50
because if you don't have a valid title to your land,
216
650964
2633
10:53
you can't borrow against it,
217
653621
1556
10:55
and you can't plan for the future.
218
655201
2022
10:57
So today, companies are working with governments
219
657969
3340
11:01
to put land titles on a blockchain.
220
661333
2443
11:03
And once it's there, this is immutable.
221
663800
2300
11:06
You can't hack it.
222
666718
1246
11:08
This creates the conditions for prosperity
223
668313
3155
11:11
for potentially billions of people.
224
671492
2168
11:14
Secondly:
225
674505
1163
11:16
a lot of writers talk about Uber
226
676295
2234
11:18
and Airbnb and TaskRabbit and Lyft and so on
227
678553
3335
11:21
as part of the sharing economy.
228
681912
2296
11:24
This is a very powerful idea,
229
684232
1664
11:25
that peers can come together and create and share wealth.
230
685920
3179
11:29
My view is that ...
231
689710
1413
11:31
these companies are not really sharing.
232
691729
3995
11:35
In fact, they're successful precisely because they don't share.
233
695748
4107
11:39
They aggregate services together, and they sell them.
234
699879
3172
11:43
What if, rather than Airbnb being a $25 billion corporation,
235
703710
4932
11:48
there was a distributed application on a blockchain, we'll call it B-Airbnb,
236
708666
5506
11:54
and it was essentially owned by all of the people
237
714196
4034
11:58
who have a room to rent.
238
718254
1732
12:00
And when someone wants to rent a room,
239
720574
2571
12:03
they go onto the blockchain database and all the criteria,
240
723169
4142
12:07
they sift through, it helps them find the right room,
241
727335
2507
12:09
and then the blockchain helps with the contracting,
242
729866
2769
12:12
it identifies the party,
243
732659
1872
12:14
it handles the payments
244
734555
1358
12:15
just through digital payments -- they're built into the system.
245
735937
3246
12:19
And it even handles reputation,
246
739207
1531
12:20
because if she rates a room as a five-star room,
247
740762
4192
12:24
that room is there,
248
744978
1216
12:26
and it's rated, and it's immutable.
249
746218
2227
12:29
So, the big sharing-economy disruptors in Silicon Valley
250
749043
4744
12:34
could be disrupted,
251
754542
1157
12:36
and this would be good for prosperity.
252
756096
2241
12:38
Number three:
253
758361
1157
12:40
the biggest flow of funds from the developed world
254
760403
2571
12:42
to the developing world
255
762998
1286
12:44
is not corporate investment,
256
764308
2262
12:46
and it's not even foreign aid.
257
766594
2281
12:49
It's remittances.
258
769605
2000
12:52
This is the global diaspora;
259
772329
1935
12:54
people have left their ancestral lands,
260
774288
2357
12:56
and they're sending money back to their families at home.
261
776669
3889
13:00
This is 600 billion dollars a year, and it's growing,
262
780582
3123
13:03
and these people are getting ripped off.
263
783729
2040
13:06
Analie Domingo is a housekeeper.
264
786555
2614
13:09
She lives in Toronto,
265
789864
1905
13:11
and every month she goes to the Western Union office
266
791793
4764
13:16
with some cash
267
796581
1539
13:18
to send her remittances to her mom in Manila.
268
798144
2960
13:21
It costs her around 10 percent;
269
801835
1893
13:23
the money takes four to seven days to get there;
270
803752
2240
13:26
her mom never knows when it's going to arrive.
271
806016
2164
13:28
It takes five hours out of her week to do this.
272
808204
2534
13:31
Six months ago,
273
811571
1152
13:32
Analie Domingo used a blockchain application called Abra.
274
812747
4580
13:37
And from her mobile device, she sent 300 bucks.
275
817771
2613
13:40
It went directly to her mom's mobile device
276
820408
2480
13:42
without going through an intermediary.
277
822912
1884
13:45
And then her mom looked at her mobile device --
278
825346
2392
13:47
it's kind of like an Uber interface, there's Abra "tellers" moving around.
279
827762
3789
13:51
She clicks on a teller that's a five-star teller,
280
831575
2738
13:54
who's seven minutes away.
281
834337
1385
13:56
The guy shows up at the door, gives her Filipino pesos,
282
836266
3080
13:59
she puts them in her wallet.
283
839370
1566
14:01
The whole thing took minutes,
284
841365
1756
14:03
and it cost her two percent.
285
843145
1863
14:06
This is a big opportunity for prosperity.
286
846269
2851
14:09
Number four: the most powerful asset of the digital age is data.
287
849637
4219
14:14
And data is really a new asset class,
288
854279
3663
14:17
maybe bigger than previous asset classes,
289
857966
2279
14:20
like land under the agrarian economy,
290
860269
2961
14:23
or an industrial plant,
291
863254
1653
14:24
or even money.
292
864931
1157
14:26
And all of you -- we -- create this data.
293
866540
3010
14:29
We create this asset,
294
869574
1782
14:31
and we leave this trail of digital crumbs behind us
295
871380
2715
14:34
as we go throughout life.
296
874119
1830
14:35
And these crumbs are collected into a mirror image of you,
297
875973
2820
14:38
the virtual you.
298
878817
1224
14:40
And the virtual you may know more about you than you do,
299
880481
2671
14:43
because you can't remember what you bought a year ago,
300
883176
2631
14:45
or said a year ago, or your exact location a year ago.
301
885831
2639
14:48
And the virtual you is not owned by you --
302
888494
2777
14:51
that's the big problem.
303
891295
1467
14:53
So today, there are companies working
304
893419
2578
14:56
to create an identity in a black box,
305
896021
3637
14:59
the virtual you owned by you.
306
899682
1611
15:01
And this black box moves around with you
307
901853
3305
15:05
as you travel throughout the world,
308
905182
1990
15:07
and it's very, very stingy.
309
907196
2070
15:09
It only gives away the shred of information
310
909290
3055
15:12
that's required to do something.
311
912369
1547
15:13
A lot of transactions,
312
913940
1289
15:15
the seller doesn't even need to know who you are.
313
915253
2473
15:17
They just need to know that they got paid.
314
917750
2468
15:20
And then this avatar is sweeping up all of this data
315
920741
3949
15:24
and enabling you to monetize it.
316
924714
2744
15:28
And this is a wonderful thing,
317
928061
1788
15:29
because it can also help us protect our privacy,
318
929873
3191
15:33
and privacy is the foundation of a free society.
319
933088
3812
15:36
Let's get this asset that we create
320
936924
1966
15:38
back under our control,
321
938914
1777
15:40
where we can own our own identity
322
940715
2008
15:42
and manage it responsibly.
323
942747
1771
15:45
Finally --
324
945817
1157
15:46
(Applause)
325
946998
4798
15:52
Finally, number five:
326
952335
1496
15:53
there are a whole number of creators of content
327
953855
3262
15:57
who don't receive fair compensation,
328
957141
2207
15:59
because the system for intellectual property is broken.
329
959372
3092
16:02
It was broken by the first era of the internet.
330
962488
3112
16:05
Take music.
331
965624
1467
16:07
Musicians are left with crumbs at the end of the whole food chain.
332
967734
3130
16:10
You know, if you were a songwriter, 25 years ago, you wrote a hit song,
333
970888
4840
16:15
it got a million singles,
334
975752
2262
16:18
you could get royalties of around 45,000 dollars.
335
978038
3521
16:21
Today, you're a songwriter, you write a hit song,
336
981583
2316
16:23
it gets a million streams,
337
983923
1453
16:25
you don't get 45k,
338
985400
1770
16:27
you get 36 dollars,
339
987194
2587
16:29
enough to buy a nice pizza.
340
989805
1947
16:32
So Imogen Heap,
341
992721
1378
16:34
the Grammy-winning singer-songwriter,
342
994123
2384
16:36
is now putting music on a blockchain ecosystem.
343
996531
3971
16:40
She calls it "Mycelia."
344
1000526
1849
16:42
And the music has a smart contract surrounding it.
345
1002399
4106
16:46
And the music protects her intellectual property rights.
346
1006529
3523
16:50
You want to listen to the song?
347
1010076
1513
16:51
It's free, or maybe a few micro-cents that flow into a digital account.
348
1011613
3357
16:54
You want to put the song in your movie, that's different,
349
1014994
2698
16:57
and the IP rights are all specified.
350
1017716
1759
16:59
You want to make a ringtone? That's different.
351
1019499
2263
17:02
She describes that the song becomes a business.
352
1022230
3209
17:05
It's out there on this platform marketing itself,
353
1025463
2809
17:08
protecting the rights of the author,
354
1028296
1967
17:10
and because the song has a payment system
355
1030287
2155
17:12
in the sense of bank account,
356
1032466
1462
17:13
all the money flows back to the artist,
357
1033952
2348
17:16
and they control the industry,
358
1036324
2235
17:18
rather than these powerful intermediaries.
359
1038583
2412
17:21
Now, this is --
360
1041757
1151
17:22
(Applause)
361
1042932
4192
17:27
This is not just songwriters,
362
1047604
1697
17:29
it's any creator of content,
363
1049325
1499
17:30
like art,
364
1050848
1467
17:32
like inventions,
365
1052339
2468
17:34
scientific discoveries, journalists.
366
1054831
2961
17:37
There are all kinds of people who don't get fair compensation,
367
1057816
3013
17:40
and with blockchains,
368
1060853
1470
17:42
they're going to be able to make it rain on the blockchain.
369
1062347
3762
17:46
And that's a wonderful thing.
370
1066133
1658
17:48
So, these are five opportunities
371
1068775
4593
17:53
out of a dozen
372
1073392
1274
17:54
to solve one problem, prosperity,
373
1074690
2301
17:57
which is one of countless problems
374
1077015
3048
18:00
that blockchains are applicable to.
375
1080087
2031
18:03
Now, technology doesn't create prosperity, of course -- people do.
376
1083036
3955
18:07
But my case to you is that, once again,
377
1087507
3875
18:11
the technology genie has escaped from the bottle,
378
1091905
3437
18:15
and it was summoned by an unknown person or persons
379
1095366
3212
18:18
at this uncertain time in human history,
380
1098602
2725
18:22
and it's giving us another kick at the can,
381
1102216
3271
18:25
another opportunity to rewrite the economic power grid
382
1105511
5117
18:30
and the old order of things,
383
1110652
1724
18:32
and solve some of the world's most difficult problems,
384
1112400
4396
18:37
if we will it.
385
1117272
1389
18:39
Thank you.
386
1119915
1192
18:41
(Applause)
