In the last days there were two Ethereum transactions  that paid about $2.6m in transaction fees each, which even for Ethereum is a bit on the high side . After the first transaction there were two major theories: fat fingers, and money laundering . Now a third one has been added . So what was it?
Securitize – the tokenisation platform – has announced that they effectuated the first dividend-like payment on-chain, as Cointelegraph reports . The payment was for the Lottery.com security token about which unfortunately apparently not much is in the public domain . So whilst the details are a bit scarce this is definitely an important step forward in the tokenisation world .
Cointelegraph has a very good article  that discusses a recent paper published by the Phildelphia Fed  on CBDCs and whether they are a threat to the commercial banking system. The article refers to a number of differing views on this topic, including that of Marshall Hayner, CEO of Metal, who is largely supportive of CDBCs, and that from IMF’s Tommaso Mancini-Griffoli who said CBDCs should be provided in public private partnership . It also provides a reference to important whitepaper  of the Digital Dollar Project . So what does this all mean?
Last week my course Security Token Strategy at University of Nicosia’s IFF started for real, and this has kept me pretty busy. Today I recorded a number of videos for the course assignments, so I did not get around recording anything for the podcast. Instead I will be sharing one of the videos with you. It is about hash functions, and more specifically about the commit / reveal pattern that they allow implementing. To make it a bit more fun we are using it to play Rock, Paper, Scissors over Slack.
The course is now full, but we’ll run it again in the not too distant future. If you are interested, contact me  or have a look at the course page .
This podcast also exists as a YouTube video .
In line with the custody theme in the podcast I am discussing here the profound changes the use of a public key infrastructure will have on the world of financial services, in particular in the area of custody.
Another piece of news fitting into the custody theme I am currently developing. As BeInCrypto reports , Gemini exchange integrates with the wallets on Samsung phones, increasing end customer security. See also the podcast I made with Dr Ken Tindell on the Samsung hardware .
