“Nike patented shoes that are tokenized as a non-fungible token (NFT) on the Ethereum blockchain, dubbed CryptoKicks. The system apparently aims to provide a way to ensure the authenticity of the goods.

The patent also borrows ideas from popular blockchain collectible cats game CryptoKitties. More precisely, it suggests that the shoes can be bred:

Using the digital asset, the buyer is enabled to “breed” the digital shoe with another digital shoe to create “shoe offspring,” and, based on rules of acceptable shoe manufacturability, have the newly bred shoe offspring custom made as a new, tangible pair of shoes.


“With the move, head of Digital Investment Banking at Santander and chairman of the Enterprise Ethereum Alliance, hailed the technology as a real-world solution for securities issuance.

We just performed an early redemption of our blockchain-based bond that we issued on September 10th, 2019. This unequivocally proves that a debt security can be managed through its full lifecycle on a blockchain (public in this case).

It’s an evolutionary step. There are no secondary markets yet, but we are on that path.”


“Hardware wallet manufacturer Ledger has announced the latest version of its Ledger Live application, adding support for Tezos (XTZ) and Tezos staking.  

This feature is typically available to users through major cryptocurrency exchanges, like Binance and Coinbase. Yet this has been problematic due to the questionable level of security on these exchanges.  Storing XTZ on a Ledger hardware wallet and then providing users with a platform to stake Tezos creates a much more secure solution.

Major exchanges that provide Tezos staking also typically charge commission fees on all rewards received. Unlike those exchanges, Ledger Live lets users choose who to delegate their tokens to without applying additional fees.

“Kraken Security Labs has found a way to extract seeds from a KeepKey cryptocurrency hardware wallet. All that is required is physical access to the wallet for about 15 minutes. 

The attack takes advantage of inherent flaws within the microcontroller that is used in the KeepKey and relies on voltage glitching to extract your encrypted seed. This unfortunately means that it is difficult for the KeepKey team to do anything about this vulnerability without a hardware redesign.”


“Based on JPMorgan’s in-house blockchain platform Quorum, the Interbank Information Network (IIN) intends to accelerate payment transactions as well as address major challenges of sharing data between banks.

Bloomberg reports that more than 80 Japanese banks have expressed their intent to join the platform. The INN is currently operating at 70 banks in Europe, Asia and the United States.


“What initially seemed like a textbook technical correction due to overbought conditions turned into a full-blown sell-off with prices falling more than 67 percent (from 465 to 153 satoshis)  in just 120 minutes.

The exact reason for the selloff is not known. Binance CEO Changpeng Zhao tweeted that the MATIC team had nothing to do with the price drop. Some investors, however, believe the selloff was caused by manipulative dumping [and] accusing the MATIC team of engineering a pump and dump scheme.

“The Shenzhen-based company will provide the Blockchain-Based Service Network (BSN) with its patented open consortium chain FISCO BCOS. Rather than a single blockchain, the consortium chain is a set of blockchain applications to serve the general public.

The announcement is the latest effort by the Chinese government to build a nationwide blockchain network to serve a range of state-controlled public services across the country, including telecommunications and energy management.”
