When paying for an online purchase with a credit card, I feel reassured that, if necessary, the charges can be disputed. Payments made using cryptocurrencies, once buried a few blocks deep, cannot be reversed.

Most web and mobile applications rely on cloud-storage solutions. Storage costs charged to developers and enterprises are determined using tiered-pricing schemes that depend on several factors e.g. amount of data stored, duration, bandwidth, latency, security, replication and distributed-designs etc. There are also contractual obligations and service level guarantees. Things are…

In a previous post, we discussed a proposal to implement storage rent which is a data access fee charged to transaction senders. In this post we present some (engineering) performance implications of storage rent. …

Storage rent is a proposal to add a data access fee to transactions on the RSK blockchain network. A key difference from current storage-related gas costs (e.g. SSTOREor SLOAD) is that storage rent depends on both the amount of data accessed, as well as the duration for which data are…

The Remix IDE is a popular environment to experiment with and deploy smart contracts written in Solidity for Ethereum-like blockchains including RSK. In this post we go over a few simple steps to run Remix IDE locally along with a local RSKJ node. …
