The current process involved in the issuance of a bank guarantee is illustrated below (Westpac, 2017).

The current process in issuing and managing a bank guarantee involves multiple pain points that can be significantly improved.

i) Physical document management — Banks currently issue a physical document, signed by tenants. The tenant must then physically deliver the document to the landlord. The landlord must produce this physical document in the event of a tenant’s failure to meet leasing obligations to make a claim. The process is inefficient, time-consuming, and costly.

ii) Tracking and reporting — The physical guarantees issued must be…

Elliptic Curves Cryptography

Elliptic curve cryptography (ECC) is an approach to public-key cryptography (watch video) based on the algebraic structure of elliptic curves over finite fields.

The elliptic curve below is an example of an elliptic curve, similar to that used by bitcoin.

Example of an EllipticCurve

The elliptic curve technique is used to create the public key derived from the private key.

How does it work:

Starting with a private key in the form of a randomly generated number k, we multiply it by a predetermined point on the curve called the generator point G to produce another point somewhere else…


What is a Hash?

Cryptographic hash functions are mathematical operations run on digital data. In Bitcoin, all the operations use SHA256 as the underlying cryptographic hash function.

SHA (Secure Hash Algorithm) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA).

To put it in simple term, a Hash function is like a black box, where you input any kind of digital information of any size, and the result (output) is an alphanumeric string (e.g.: 0xe3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855). In the case of SHA-256, the output is 32 bytes. This function has 2 characteristics:

1) Unequivocal: the hash (output) is like…

Harry Markowitz’s 1952, modern portfolio theory has been the cornerstones of asset allocation and portfolio construction. In reality, the correlation between traditional asset classes has increased steadily over the past decade. Seemingly unrelated assets moved in lockstep, and portfolios once thought to be diversified did not weather the storm.

This has led to some investors exploring alternative beta strategies as an alternative to conventional market portfolios. Alternative beta strategies area two-fold. One approach is the “risk-based approach” and the other is the “factor-based” approach.


Public, Private or Consortium?

A private or a consortium blockchain platform, as opposed to the public platform that Bitcoin uses, allows the user to retain control and privacy while cutting down costs and increasing transaction speeds.

For a Blockchain, purists this is not very impressive. A private platform effectively kills their favourite part of this nascent technology: “Decentralization”.

They see the advent of private blockchain systems as little more than a sneaky attempt by big banks to retain their control of financial markets and some go to the extent to relate it all to the so-called money printing by the central banks.

In a…
