Polkadot: Scaling Blockchains or Securing Blockchains through Collaboration?

Polkadot is revolutionising the way blockchains operate and interact with one another. This secure, scalable, and interoperable network technology is laying the groundwork for the next web and the associated disruptions.


What exactly is Polkadot?


Polkadot is the blockchain of blockchains, with an infrastructure that connects several different blockchain networks. Parachains and parathreads are blockchains that connect via Polkadot relay chains and share security. They use specialised bridges to connect to external networks.


A consensus mechanism that governs the whole network is formed by using a single relay chain to connect all participant blockchains. This agreement serves as the foundation for the network's shared security. We'll look at the advantages and disadvantages of using a single-point security system.


We are a Polkadot development firm with skilled Polkadot security auditors who will assist you in determining the integrity and security of your network at Cryptoauxiliary. In addition, we have made significant contributions to blockchain development, and our background qualifies us to close gaps in Polkadot or blockchain networks.


The network's security


A shared security framework is used by the Polkadot network. In written documentation, this is sometimes referred to as pooled security, and it has been a selling feature for many blockchain platforms interested in joining the Polkadot network as a parachain.

Bridges vs. Parachain


Each parachain connected to the Polkadot Relay Chain is leased a parachain slot by design, allowing them to benefit from the business security provided by the Relay Chain validators. If the interchain link is formed via a bridge protocol, each chain is considered independent and must have its own economic security and validators.


Polkadot agreement


The mismatch between chain security will be absent on Polkadot. The Relay Chain validator is configured during the parachain's transitions to offer security whenever a parachain connects to the Polkadot network.


The beauty of this architecture is that just a few collator nodes will be required to keep the validators up to date on the latest state transitions and proofs/witnesses. Validators will only need to look for the parachains that have been assigned to them. This procedure allows freshly created parachains to immediately benefit from Polkadot's existing overall security.




Polkadot's Weaknesses


The scalability of the security system is a fundamental challenge in the Polkadot protocols. Lower market cap alternative coins have a tendency to be filtered out while larger market cap altcoins fill their blocks, resulting in lower market cap altcoins having a weaker layer of security and being more vulnerable to cyber-attacks.


An attack on Ethereum on January 10, 2019, is a classic example. A total of 219,500 ETC was double-spent by an anonymous attacker (approximately 1.1M USD). This is where you can rely on Cryptoauxiliary's Polkadot security auditors to audit your network for security bridges and have our professionals resolve any potential problems.


Polkadot, for its part, overcomes security scalability by funnelling all economic incentives to the Relay Chain, allowing parachains to benefit from higher fidelity at genesis. Independent chains, on the other hand, must work to raise the value of their coin in order to make it difficult or impossible for well-funded adversaries to attack them.




Performing a Polkadot Security Audit

Polkadot is built in a complicated and dependable manner to ensure network security. However, some gaps must be filled, and a security assessment is essential. It's crucial to verify that the parachain's code is right, especially when it comes to critical needs like assuring the immutability of the parachain's state after the connection is established.




Only when the network's fishermen discover fraud are they rewarded.


To achieve compliance, it is necessary to ensure that:


1) Fishermen should be rewarded for independently testing validators and reporting early.


2) To discover and report compromised blocks, fishermen and other validators require a longer finality time.


3) Because independent blockchains cannot be reversed, only the last block should allow transactions.




Polkadot is not only scaling up current blockchains via parachains and bridges, but they're also taking on the massive task of integrating common security across many blockchains. They're tackling this issue with a system that enables for collaboration and, as a result, the prevention of potential attack vectors.


Although the Polkadot architecture may have flaws, fishers are always on the lookout for assaults, which helps to prevent parachain validator collusion. As a result, having permanent fishermen who will be compensated for their efforts will be a fantastic idea.
