How can Blockchain Testing ensure greater Security, Performance, and Scalability?

The scalability and performance of IT applications and systems are supposedly the key non-functional requirements for any business enterprise. These also help enterprises understand the readiness of any project for implementation. Due to its decentralized and distributed model, which enables peers in a network to collaborate, Blockchain shares similar considerations with Bitcoin. Here, each peer node needs to compute and communicate with other nodes to validate transactions and update a shared ledger. The salience of blockchain technology has hit home in recent times, with digital and cryptocurrencies such as bitcoin becoming the talk of the town. 

According to techjury.net, the global blockchain market is estimated to garner revenue to the tune of $20 billion by 2024. Also, the total worldwide spending on blockchain technology solutions in 2021 is expected to be around $6.6 billion (Source: Statista). So, with so much buzz around blockchain technology, it is imperative for businesses dealing with cryptocurrencies and this technology to ensure their security, scalability, and performance through blockchain testing or assurance. However, before delving into blockchain quality assurance, let us first understand what blockchain is all about.

What is a blockchain?

A blockchain is a decentralized, transparent, shared, and digitized public ledger that records every transaction and tracks assets in a network. It relies on a computer network where peers operate in a collaborative way. The best thing about the blockchain is the fact that every transaction recorded is encrypted and comes with a timestamp. Also, each record in the decentralized database carries a link to the previous one. In any blockchain network, the participants are the nodes sharing a ledger that is updated through peer-to-peer replication. A blockchain network eliminates duplication and therefore, is economical and efficient. Since the architecture is based on consensus, the transactions are validated, authenticated, secured, and verifiable. The above-mentioned factors make blockchain the best network to record, track, and store transactions.

Since transactions in a blockchain network are replicated at a high volume, the network may face latency issues. Also, some key considerations should be factored in while conducting blockchain testing of applications.

Key considerations for blockchain app testing

The main factors to consider while conducting blockchain application testing are as follows 

Smart contract testing: Similar to what is done in API testing, the methods for smart contracts should be validated. These may include validating the methods and verifying the conditional statement and the boundary value. Thereafter, the validation for encrypting the smart contract should be transmitted to another system through a distributed ledger. At the unit level testing of the blockchain architecture, all APIs for the smart contract are tested individually followed by integration testing.

Node testing: A blockchain functions through network nodes in a distributed peer-to-peer network using an authentication protocol. It checks whether the majority of nodes have approved the transaction and validated the block. This is why all nodes must be tested independently.

Performance: For any blockchain performance testing, information related to network latency and based on expected transaction size, block size, and network size should be made available. It also needs details of the duration of a query, returning the output through a specialized authentication protocol. Thus, any blockchain performance testing is conducted on such parameters, and to prevent any abrupt downside or peak, cloud-based features such as auto-scaling should be leveraged.

Security: Blockchain has been envisioned as a secure way to record transactions in a network, and so, its security should be maintained at all levels and at all times. To ensure the integrity of the network, all transactions are encrypted cryptographically. However, should the identity layer get hacked, there is no stopping the instantaneous transactions. Hence, blockchain security testing should overcome challenges as mentioned below:

Wallet signature method

Access and authentication

Private keys

Secure hash and consensus algorithm

Vulnerability assessment

Follow OWAPS guidelines for web and mobile applications

Validating information

The blockchain testing framework has to deal with more challenges that are not limited to the above few. These mainly relate to the implementation of blockchain in an application. Nonetheless, the above-mentioned factors act as guidelines for testing blockchain implementations effectively and with proper verification and validation.

Further, to ensure greater trust, security, performance, and scalability of the blockchain architecture, testers should follow a suite of best practices as mentioned below:

Shift-left testing: As more blockchain teams are implementing Agile and DevOps methodologies in the value chain, employing the shift-left method of testing becomes important. With shift-left testing, teams can conduct various tests early and reuse them continuously through a blockchain test automation framework. By shifting testing up in the value chain, early and iterative feedback on errors is received and acted upon. Thus, by fixing defects early on in the blockchain development, their impact on the business can be minimized or eliminated.

API testing: This type of testing addresses the interaction of applications inside and outside the blockchain ecosystem. Let us understand its importance with an example. When a transaction is submitted to an API, it ought to be validated under specific rules and guidelines to create an updated order. The order is subsequently distributed by the blockchain and the API receives a confirmation of the same. So, testers must validate the applications’ interactions inside and outside the blockchain at every step and ensure the correct handling of API requests.

Functional testing: Functional testing for blockchain applications evaluates business processes and scenarios. It does so by keeping blockchain components such as block size, chain size, data transmission, and the addition of a block into consideration. It plays a crucial role in assessing the business circumstances and authenticating every transaction that gets added to the blockchain.

Integration testing: Since blockchain deployment can be across several systems, locations, and environments operating in parallel, the need for several components to seamlessly interface with each other becomes critical. With integration testing, all touchpoints including the APIs are tested for validation.

Conclusion

In this day of rising cybercrime, Blockchain is fast emerging as a technology that can offer secure payments. As a suitable platform for digital transformation, it offers a cost-saving, decentralized, disruptive, and secure alternative for record-keeping and facilitating transactions. However, it is only with blockchain assurance that the quality, integrity, scalability, performance, and security of the framework or network can be assured.

Bundesbank schließt Blockchain Test mit gutem Ergebnis ab

Inwieweit sich der aktuelle Testlauf letztlich auf mögliche schnellere Maßnahmen zur Regulierung durch die deutsche Regierung auswirken kann, ist unklar. Trotzdem sind die Versuche der Bundesbank sowie der Deutschen Börse ein wichtiges Signal.

Zwei Prototypen haben Testlauf erfolgreich abgeschlossen

Deutsche Börse und Bundesbank haben zum Ende der Woche vermeldet, mag habe einen Versuch mit zwei neuen Prototypen der Blockchain-Technologie endlich abgeschlossen. Gemeinsam wollte Bank und Inhaber der Börse Frankfurt herausfinden, wie es um das Blockchain Potenzial im Bereich der Wertpapiertransaktionen steht. Vielfach wurde schließlich von Experten in der Vergangenheit betont, wie nützlich beispielsweise Ethereum und andere Kryptowährungen in diesem Umfeld sein könnten. Das Ergebnis der Versuche mit beiden Modellen jedenfalls macht auf jeden Fall Hoffnung. Das Potenzial der Blockchain sehen die Verantwortlichen als bestätigt an. Nicht nur Orders, auch Zahlungen wurden testweise abgewickelt Neben der reinen Transaktionsabwicklung im Wertpapierbereich wurde im Test auch die Anwendbarkeit der Blockchain bei Zahlungen samt Zinsabrechnungen sowie Fälligkeits-Erstattungen im Bereich der Anleihen auf die Probe gestellt. Hier wie dort präsentierte sich der Versuch als Erfolg, wie es in der Pressemitteilung von Bundesbank und Deutscher Börse heißt. Als Grundlage für die Blockchain-Neuentwicklungen diente zum einen die bekannte Digital Asset Plattform und andererseits das Format Hyperledger Fabric. Wir sehen: Es tut sich langsam etwas, damit sich die Blockchain-Systeme von Bitcoin und anderen Währungen endlich auch in Deutschland durchsetzen können. Vielleicht werden sich daraus bald wie in den USA zukünftig neue Arbeitsstellen im Blockchain-Bereich entwickeln Systeme müssen den gesetzlichen Vorgaben gerecht werden Das aktuelle Forschungsprojekt im Zusammenhang mit dem „Blockbaster“-Projekt (steht für „blockchain based settlement technology research“) der beiden deutschen Institutionen könnte also richtungweisend sein und in Zukunft dafür sorgen, dass die Infrastruktur am deutschen Finanzmarkt allmählich für diesen Teil der digitalen Welt geöffnet wird. So heißt es weiter, dass bereits an Optimierungen der Prototypen gearbeitet werde, um die Ergebnisse des ersten Performancetests bald zu übertreffen. Im Sinne der Erfüllung geltender Finanzmarkt-Richtlinien setzen Bundesbank und Deutsche Börse auf eine geschlossene Architektur, die lediglich Nutzern mit entsprechender Zulassung offensteht, so die Stellungnahme aus dem Vorstand der Deutschen Bundesbank.

Ethereum Update by Vitalik Buterin: Roundup Round III

New Post has been published on https://cryptocurrencies.space/ethereum-update-by-vitalik-buterin-roundup-round-iii/

Ethereum Update by Vitalik Buterin: Roundup Round III

Over the last month and a half we saw vigorous ongoing research and development on all sides of the Ethereum roadmap, and progress is rapidly starting to translate into real results that can be run and verified inside of an Ethereum client.

On Metropolis:

Agendas for core dev meetings 15 and 16 here: https://github.com/ethereum/pm/issues/13and https://github.com/ethereum/pm/issues/14

List of accepted EIPs here: https://github.com/ethereum/EIPs/blob/master/README.md(mostly agreed on, though we are still going back and forth on details such as gas costs)

Most of the EIPs have been implemented in C++ and Python and are being implemented in other clients; tests are being actively written and added here https://github.com/ethereum/tests/tree/develop/GeneralStateTests (see the various branches for different tests)

Clients that have not implemented GeneralStateTests could provide a docker image for   Hive testing (contact Martin Swende). All GeneralStateTests are being converted into BlockChainTests and run on Hive.

A release date has still not been finalized; the general consensus is to wait until all tests are passing on major clients before setting one. Because of the rapid increases in block difficulty, the ice age continues to be delayed; current prognosis assuming no further increases (arguably a very pessimistic estimate) is that block times will not exceed 20s until July 12, and will not exceed 30s until Sep 12.

The Ethereum blockchain has hit several new all-time highs:

Difficulty (450 TH) and hashrate (28.5 TH)

Transactions per day (187115, or ~2.16 per sec)

Gas usage per day has not yet reached the all-time high of Jun 18, when the blockchain was heavily spammed as part of the DAO attack and various counterattacks, but is nearing it with an 11-month high of 10.7 billion per day. That’s 1991878 gas per block, or ~45% full blocks for the day (reminder: gas limits are dynamically adjusting, so congestion with rapidly increasing fees is not likely) . Uncle rate on that day was only ~7.4%.

On various side projects:

ENS has been deployed, and auctions are ongoing.

Whisper is getting a proper API, which is in alignment with our general RPC, the API should be ready soon and a workable whisper version will be released.

Swarm has made a number of significant improvements, including (i) supporting directory upload and download via the http interface, (ii) full FUSE support, (iii) a new protocol pss for node-to-node messaging, (iv) replacing the chunk hash with a Merkle tree hash to enable more efficient data inclusion proofs. Progress toward POC3 is going at full steam.

Pyethereum development has picked up quickly:

Jan Xie and his team have successfully synced a pyethapp node to the most recent block on the mainnet.

Several bugs in the implementation have been fixed, and the client is now passing all state tests and most pre-Metropolis blockchain tests. Work to find the remaining issues is ongoing.

Most Metropolis EIPs have been implemented, including the four new precompiles.

The tester module has been revamped so that it is fully based on the Chain module, and a new and more convenient interface has been added, including functionality such as creating state tests.

Casper research is now in the process of fine-tuning the incentives for liveness, and implementing the logic inside of pyethereum. This includes:

The validator daemon

The hybrid Casper fork choice rule

Casper contracts including tests

Signature validation code, including for ECDSA and quantum-resistant hash-ladder signatures

Other research stuff:

Substantial work has been done on sharding, and specifically the dreaded “data availability problem”; see here: https://github.com/ethereum/research/wiki/A-note-on-data-availability-and-erasure-coding

The Sharding FAQ has been updated

Greg Colvin’s “EVM 1.5” proposals are now EIP drafts 615 and 616

Geth development:

Removed the artificial 20 shannon minimum gas limit from the transaction pool, enabling Geth nodes to accept and relay arbitrarily priced transactions. This should help enable a real gas market.

Identified a sync regression for HDD users, resulting in a heavy rewrite of fast sync code, making it much more robust and stable.

Identified and fixed a few EVM bottlenecks, causing complex contracts to execute up to 60% faster doing up to 95% less memory allocations.

Polishing the light client and its mobile bindings in collaboration with Status, Walleth and others. Preliminary proof-of-concept done for light client event retrievals.

Working on a new filtering mechanism, with very promising results, reducing the time required to filter the entire blockchain for contract events from minutes to seconds.

Investigating a new mining strategy, which should move transaction processing for miners completely parallel to mining, hence reducing the overhead of transaction inclusion to 0. This should permit miners to lower fees without transactions impacting the probability of finding blocks and/or having them included.

Slowly adding minor polishes to Puppeth, Clique and Rinkeby, such as a tiered faucet for Ether withdrawals, configurable gas dynamics for private network miners and automatic ENS integration.

An external security-audit has been performed by Truesec AB. No critical issues were found.

C++ development:

the monitoring node achieved a full sync to the mainnet

metropolis EIPs are almost complete

work on fast sync and snapshot sync has begun

Testeth tool has new option –statediff for debug information on a praticular test case as well as new test format  GeneralStateTests (enhancement of the old statetests) [4074]

Remix:

almost finished a new static analysis module that can detect reentrancy bugs (externally contributed by “soad003”) [508]

added a folder view to show open files inside folders – files imported via e.g. import “github.com/ethereum/solidity/std/StandardToken.sol”; are now visible in the folder view [449]

debugger can now display mappings [498]

rearranged tabs to provide better overview [496]

Solidity:

we released the unified standard json interface to interact with the compiler [1639]

added “interface contract” feature[1688]

added some more safety checks: statements without effect, and unary plus and unused variables [2139, 2152, 2199]

further work on the new intermediate language including web assembly and EVM1.5 backends [2129 and lots more]

almost finished work on exporting and especially also importing the AST (this will allow mutation testing and lots of other extensions) [1810 and others]

Mist:

Decouple geth specific hard-coded node and network handling, allow for arbitrary nodes and networks defined by local or remote clientBinaries.json

Refactor of the settings backend in preparation for a settings UI

Added macOS and Windows Code-Signing, preparing github/swarm based auto-updater

Many of the audit findings will incorporated in the coming releases

Changes to the provider will make Mist and other Projects like MetaMask and status.im more future proof, as developers don’t need to depend on high level libraries not changing over time. There will be a few announcements concerning the new provider. Discussion about that is happening at https://github.com/ethereum/interfaces/issues/16

Web3.js

We are currently adding generation and signing with private keys right into web3.js. So that you can easily create wallets and sign messages in your dapps. You can find the current experimental docs here: http://web3js.readthedocs.io/en/1.0/web3-eth-accounts.html

The next steps will be adding @maiavictor’s swarm library and the new whisper API and the new web3.js should be ready for test drive by the community.
