Reading Time: 3 minutes

In this article we review the main ideas presented in the last cryptoassets valuation Satis Group’s article published by Bloomberg. Satis Group is an ICO advisory firm which has helped model one of the first bitcoin valuation in 2014. According to their report, the cryptoassets ecosystem forecast is promising. Bitcoin and Monero cryptocurrencies are both expected […]

A Review Of Cryptoasset Valuation Frameworks

Reading Time: 15 minutes

Some people think that cryptoassets are bubbles without intrinsic value and this is mostly due to the fact that they don’t know how to analyze them. Cryptoassets can’t be analyzed with the same valuation frameworks used in stocks and other non-cryptoassets.  However, the crypto-community has been generating some useful valuation models. In this article we are […]

ERC20 Token Development on RSK with OpenZeppelin and Web3.py

Reading Time: 7 minutes

In my last article, I’ve shown you how to make a Solidity ERC20 Token for the RSK Mainnet, how to import and use OpenZeppelin libraries and contracts, and how to use Truffle to deploy and interact with our contract.

Although we succeeded in our quest and accomplished our objectives using Truffle, eventually this suite might present failures when you are sending transactions, deploying or managing accounts. In our case, while following the previous article instructions, I’ve had problems managing newly created accounts in Truffle and sending transactions.

ERC20 Token Development on RSK with OpenZeppelin

Reading Time: 8 minutes

In the last article, we have seen how to build an RSK node in our computer, select the proper network for development, configure Truffle to connect and deploy our future contracts, add accounts to our node and obtain funds to use them to pay the gas.

You should have now your node in the selected network fully synced, and at least one account with funds configured in the truffle and RSK node config files for our deployments.

In this article, we’ll be discussing deployment and interaction of Smart-Contracts over the RSK network. Our contract will be an ERC20 Token, based on the OpenZeppelin libraries, and we will deploy it directly into the Mainnet.

Quantum Resistant Public Key Exchange: The Supersingular Isogenous Diffie-Hellman Protocol

Reading Time: 1

Synopsis of our full article: Though the research on quantum computers is still facing big challenges, there is also some progress in this field. The National Institute of Security and Technology (NIST) recently published a report on Post-Quantum Cryptography which informs about new developments. They believe that it is time to think of quantum-safe primitives, […]

Interdependent Transactions in Bitcoin, RSK and Ethereum

Reading Time: 5 minutes

A recent paper titled The Blockchain Anomaly presents the difficulties the authors encountered when trying to make two transactions interdependent such that the second transaction cannot be executed without the first being confirmed. Although the paper may be useful as a guide, the title is misleading since Bitcoin does not guarantee the order of transactions (no […]

ECDSA Security in Bitcoin and Ethereum: a Research Survey

Reading Time: 1

Elliptic curve cryptography is becoming more and more popular. One of its main supporters is the cryptocurrency system Bitcoin which uses an elliptic curve scheme for their digital signatures. Smaller key size, a more efficient implementation than the RSA system, and a similar level of security make elliptic curve cryptography an interesting alternative to RSA. […]
