Korea Blockchain Week
KBW puts a conference on a resort above the Han River and wraps it in three hundred side events you get invited to by email an hour before they start. None of that works on venue Wi-Fi.
Dates are the ones this event has used in recent years. The organiser had not published 2026 days when this page was written on September 8, 2026; check the official site before booking flights.

Prices checked September 8, 2026 against Airalo. We'll update this table, including if we stop being cheaper.
이유
Side events are announced on Telegram and Luma, not on a printed schedule
Google Maps cannot route you in Korea; Naver Map and KakaoMap can, with data
Kakao T is how you get a taxi, and it is an app, not a rank
Venue Wi-Fi at 13,000 people is a coin toss.
지혜
The venue sits east of the river. Budget an hour from Gangnam in evening traffic, twenty minutes at dawn.
Luma is where the real schedule lives. Check it hourly; the good ones cap at eighty people.
Card works nearly everywhere. Keep ₩30,000 in cash for the pojangmacha tents afterwards.
KBW usually lands next to Chuseok, when half the country is travelling. Book beds and trains early.

About two minutes. We email a QR code; scan it before you fly.
For Korea: 1GB a day at full speed, then unlimited at 5Mbps. We print the number instead of hiding it.
