A DAG is a network of individual transactions linked to multiple other transactions. There are no blocks of transactions in DAG networks. A blockchain is basically a linked list, while a DAG is a tree, branching out from one transaction to another, to another and so on without ever repeating.
The end result: an unprecedented potential for highly scalable and fast information flow on a completely decentralized network. Blockchains are initially secure but slow down at scale where DAG's require large scale decentralized networks to operate efficiently and securely and improve at larger scales where blockchains are not viable. The seafood industry operates under slim margins and given the need for colossal data collection in a supply chain with scant computational resources, and an environmental crisis that requires universal on the ground participation to reverse, DAG based solutions can become viable and invaluable with mass adoption.
Distributed-ledger-based solutions for large-scale application deployment, transaction settlement, and user governance offer significant benefits in the areas of transparency, security, and cost-effectiveness. However, three major barriers to broad adoption remain (Critical Factors): a) scalability and performance, b) future-resistant security, c) resource requirements and environmental impact, and d) user-friendliness and transparency.
With the advancement of DAG, we’re looking at a future where high functioning and minimum transaction fee chains are possible. That means users can send micro-payments without heavy fees like Bitcoin or Ethereum.
The "Internet of Things", however promising, requires respect of users’ rights and safety with the help of altruistically designed crypto protocols that can handle massive, real time data. DAGs will be instrumental in this respect.
As the Internet transformed and commoditized how society communicates, blockchain will transform and commoditize how society agrees, trusts, and transacts.
In real life IoT experiments, DAG based network transaction speed increases linearly with the number of nodes. DAG systems use consensus between nodes which can even run on legacy hardware.
The decentralized nature of DAG systems, paired with one time and multi-layered encription allows for unbreakable security needed for the networked consesnsus of transaction authenticity. These systems can withstand quantum-computer attacks and a 1/3rd corruption of the network.
DAG systems require no high energy, high processing power "proof-of-work" validation of blockchain systems which have spawned an explosion of power-hungry customized hardware solutions to meet basic network needs.
Blockchain systems require cumbersome and sometimes insecure "wallet" systems to maintain private keys, specialized hardware, and innvigable or non-existant user interfaces, while the DAG system Seafood Commons is working with achieves ease of use through secure biometric authorization, eliminating the need for a wallet, making the distributed-ledger practically invisible in the user experience, while mantaining complete transparency of the network.
