The Singapore University of Social Sciences (SUSS) FinTech and Blockchain Group just had a workshop and their materials are online.

In this two-day workshop conducted by Andras Kristof, the Chief Technology Officer of Yojee, he elaborated the basics of blockchain systems and ICOs, explained the key concepts of smart contracts, their benefits and limitations, and demonstrated the process of token swaps with the use of a hardware wallet.

The articles are slowly making their way online, but you can already read Blockchain basics, and Blockchain Technology Evolution.

I look forward to seeing the remaining four articles too.

Trouble cashing out your cryptoasset fortunes?

Via the FT: Bitcoin investors struggle to cash out new fortunes (paywall).

Mortgage lenders and brokers are avoiding cryptoasset riches. Even after converting to sterling, lenders wanted to know the source of income. However nothing in law prevents this, so, “Many lenders including Coventry Building Society, Skipton and the Yorkshire Building Society said they would accept deposits derived from bitcoin sales.” All that said and done, banks really do ask for your previous six months bank statements, so if you had money before, this really shouldn’t be a problem.

In addition, via the FT, Investors face barriers trying to turn bitcoin profits into pounds (paywall), it seems that there are hurdles to bringing money back into the UK, since exchanges lack banking relationships with UK banks. There seems to be more comfort with European banks and cryptocurrencies. Interesting to see banks like Standard Chartered not allow bitcoin-related transactions, while Barclays may do a crime investigation, and NatWest may alert customers of potential fraud.

Seems a matching exchange, i.e. Bittylicious, seems like the workaround. It seems quite a bit like Remitano. Go back to peer-to-peer.

Singapore Airlines private blockchain for loyalty

The Edge reports, SIA’s KrisFlyer programme to launch blockchain-based digital wallet app, and Daniel Yap also adds on, SIA’s “blockchain Krisflyer miles” is not pointless, but it’s not spectacular. What they’re doing:

  • blockchain-based airline loyalty digital wallet
  • SIA-owned private blockchain involving only merchants and partners
  • goal: “unlock the value of KrisFlyer miles to enable everyday spending at retail partners”
  • digital KrisFlyer miles (what a point is called), to be used at Point-of-Sale (POS) transactions across participating merchants

Why not use a traditional database? A good analysis by Aaron Wong, from the perspective of a frequent flyer, Why Singapore Airlines’ Krisflyer blockchain initiative worries me. Scroll down to So what is Singapore Airlines doing?.

Yes, it is called a license violation, and with things like Github these days, you might not just want to run sed through someone else’s source code and replace strings! See the github issue, and the commit fix.

Irrespective of other accusations of plagiarism, if people are thinking about open sourcing their code, they need to abide by open source rules. Some of this is legal (like this case), some of it is governance related, and some of this is community related.

As always, for consulting about open source, don’t hesitate to drop me a line.

Why Decentralization Matters – spend the 8 minutes to read this. It is excellent. Chris Dixon gives you a good idea why Web 3 makes sense, how the Internet architecture really gets made and why cryptonetworks clearly have a future. I for one remember an Internet before the centralised Internet, which explains my excitement about the decentralised Internet.

Today I saw an interesting app, Graphite. It is sold as: “Graphite is powered by Blockstack and is the first truly decentralized and encrypted replacement for Google G-Suite and Microsoft Office” How many of you, use Blockstack? Apps are popping up for sure.
