## bonjour, FOSDEM!
13+
14+
.code ./code/hello.go
15+
16+
- manfred touron (@moul)
17+
- built scaleway, berty, now gno
18+
- stuck with go for 10 years
19+
- unapologetically open-source maximalist
20+
21+
## intro
22+
23+
- go is an amazing language: simple, efficient, safe
24+
- not built for decentralized apps (dapps)
25+
- existing decentralized app platforms are complex, fragmented, and unfamiliar
26+
- what if you could write dapps in pure go?
27+
- meet gno: go for dapps, designed for modularity, composability, and safety
28+
29+
## gno in one sentence
30+
31+
gno is a **transactional vm**<br/>
32+
that lets you write **decentralized apps** in **go**,<br/>
33+
with built-in **state persistence** and **safe execution**.
34+
35+
## gno hello world
36+
37+
<br/>
38+
<br/>
39+
<br/>
40+
<br/>
41+
<br/>
42+
43+
.code ./code/hello_world.gno
44+
45+
## the gno paradigm
46+
47+
- **no json, no grpc**: function calls instead of rpc
48+
- **no orm, no db drivers**: state is a first-class concept
49+
- **no external dependencies**: everything is go code
50+
- **no bytecode**: interpreted, readable go syntax
51+
- **no hidden magic**: all code is visible and auditable
52+
53+
\... but it's just like go.
54+
55+
## persistence: counter.gno
56+
57+
.code ./code/counter.gno
58+
59+
- global variables persist across transactions
60+
- no need for external storage or db
61+

75+
76+
## interoperability: alice.gno & bob.gno
77+
78+
Another app could use micropost...
79+
80+
.code ./code/interop.gno
81+
.code ./code/interop2.gno
82+
83+
- call functions from other contracts like normal go packages
84+
- no need for low-level calls or address casting
85+
86+
## conclusion
87+
88+
<br/>
89+
90+
.code ./code/we-are-building.txt
91+
92+
<br/>
93+
94+
- gno makes go the first-class language for decentralized applications
95+
- if you know go, you already know gno
96+
- opportunities for developers to contribute and innovate
97+
