IBM Patents A System That Creates Audited Blockchain ‘Checkpoints’



Aside from Mastercard who recently won a patent about coupons and their use online, IBM has also won two patents for a system that verifies the integrity of a blockchain. The system developed by IBM will certify that the blockchain has passed certain audit requirements in particular periods of time.

Both of the IBM patents in regards to this were approved on May 31 and are related to describing the certified and audit-able “checkpoints”. Their main goal is to allow businesses to satisfy the regulations for data verification and retention when they are connected to the network.

Understanding the Blockchain Based Checkpoints System

As such, the first patent is based on a single point of a checkpoint and what constitutes it, according to IBM. Here, the requirement is that all peers and nodes that perform validation should achieve consensus about the validity of the blockchain at the time of the snapshot.

According to the summary found in the first patent’s information:

“Before a checkpoint is certified, it must be consistent, meaning that all validating peers must reach the same state (value) for the checkpoint. Preferably, the checkpoint is a compression of the current blockchain world state into a compact representation (e.g., a hash value) of the ledger that is consistent across the (validating) peers.”

Obviously, the idea is for the audit to go back to the Genesis block and work its way up from there. This has been done to make sure that the immutability and consensus are kept in tact up to the point in time that is being certified.

When it comes to the second patent, it actually builds on the first but with the description of how each checkpoint can be audited. In this patent, IBM implements and patents a process that audits the checkpoints – where businesses can also refer back to any certified checkpoint and reconcile data from the blockchain.

As the summary from the second patent says:

“To have a certifiably-auditable blockchain, an auditor should be able to rerun the transactions between checkpoints and then compare the value of the latter checkpoint with the value recorded in the ledger. The first step in this auditing process is to double check the hashes of all the blocks in the chain. To be thorough, the signatures on all transactions should be checked, although the hashes on all blocks ought to be sufficient.”

As we can all see, IBM is focused on products and services for enterprise-level businesses that run on the blockchain. As a true innovator, IBM is focused on blockchain scaling, auditing and supply chain management.

Deloitte Features Blockchain In Its Annual Tech Trends Report

The latest news around blockchain on our DC Forecasts crypto news site show that the technology is gaining a lot of attention from different angles. As of recently, blockchain has been featured as 'a disrupting technology' in the Tech Trends 2019 report that was published by Deloitte, one of the global leaders in consulting and auditing. As one article states, the Big Four audit and consulting firm has put blockchain as one of the technologies that is rapidly growing and is on a path towards mass adoption. The report also cites one International Data Cooperation (IDC) projection which states that worldwide spending on blockchain solutions will reach $9.7 billion in 2021, while another predicts the number to hit $11.7 billion by 2022.
“Today, blockchain is to trust what the web was to communication: a profoundly disruptive technology that transforms not only business but the way humans transact and engage," the report notes.
Deloitte also agrees that blockchain is viral, saying that the technology is “capturing both mindshare and investment is remarkable considering that a few years ago the word blockchain was known only through its relationship to cryptocurrencies. One of the areas where blockchain is likely to develop in the coming year, according to Deloitte, is the technology that includes "gateways, integration layers and common standards." However, Deloitte also shared the obstacles of implementing the technology, mainly related to the time-consuming operations, lack of standardization, high costs and complex applications.

Stellar’s XLM Token Added To Greyscale’s Crypto Investment Trust Fund

Greyscale, the digital currency investment group officially launched their latest fund that is solely dedicated to Stellar Lumen’s Token XLM according to their tweet reaching our crypto news today. Greyscale has now approximately nine crypto funds that it operates and the company renamed all of their single-currency products to trusts. The company works as a ‘’single-asset investment products with maximum exposure’’ to Bitcoin, Ethereum, Litecoin, Ripple, Bitcoin Cash, and Ethereum Classic. The managing director Michael Sonnenschein said on an occasion that this newest addition is happening because of the investors demand to try to get more exposure to XLM’s price movements:
 “I think the theory is a sound one,” he said about Stellar’s business proposition for bridging crypto to fiat currency conversions. An American bank may be keeping large amounts of currencies in foreign banks, and to be able to bring those balances of foreign currencies onto a balance sheet as working capital is valuable. Financial institutions won’t be required to hold balances all over the place. This will improve efficiency and shore up balance sheets for other uses.”
Stellar had amazing performance especially in Q4 after striking a deal with crypto wallet provider in order to start distributing XLM that is worth $125 million in an airdrop, hoping to increase bigger awareness and adoption. In the meantime, Greyscale had a mixed year in 2018 after bitcoin dropped to its 15-month low at $3,130. The company’s Bitcoin Trust was worth less than $1 billion for the first time in 2018. According to the crypto industry newsletter Diar’s research, Greyscale in the same apparently had holdings just over one percent of the total BTC in circulation. After the announcement, Stellar increased up by 1.22 percent.

Bitcoin ATM Operator Coinme To Start Selling BTC At Coinstar Counting Machines

The Bitcoin ATM operator Coinme based in the United States reaches our blockchain news today after partnering with Coinstar to be able to sell Bitcoin at coin-counting kiosks that are owned by Coinstar according to an official press release published on January 17. Coinme is actually the first bitcoin ATM operator to obtain a license in the US back in 2014 and was quickly able to add multiple locations around the US. The CEO of Coinme Neil Bergquist noted:
