The interface is designed with simplicity at its heart. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.ĭigital data comes in all shapes, sizes and formats in the modern world – CyberChef helps to make sense of this data all on one easy-to-use platform.
In this way, the accumulator hash is a very simple, but powerful way of ensuring the integrity of transactions on the ledger.A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. If any of the instructions have been tampered with inside the transaction, then the transaction id will change. We can confirm that our accumulator calculations are correct by comparing them to the values stored in the ledger:Īnother very important factor to note is that id of a transaction is a hash of all the instructions contained within the transaction. As long as transactions occur in the same order, with the same transaction ids, then every validator node will independently calculate the same accumulator hash values and can be confident that they have not received modified transaction data. The calculation of the accumulator hash is repeated for every transaction that occurs on the ledger. Print("Second Accumulator hash:", second_accumulator.hex()) Inner.update(first_accumulator + second_transaction_id) Print("First Accumulator hash:", first_accumulator.hex())
#DOUBLE SHA256 HASH CALCULATOR CODE#
The code snippet below illustrates the calculation of the first 2 accumulator hashes on the mainnet Radix public network: import hashlib To calculate the second accumulator hash, we take the result of the previous (parent) accumulator hash, append the transaction id of the second transaction, and perform the double sha256 operation again. To calculate the very first accumulator hash we: The accumulator hash is calculated by hashing the previous accumulator hash with the current transaction id.Īt the genesis of the Radix public network, the initial accumulator hash was set to 32 bytes of zeros: 0000000000000000000000000000000000000000000000000000000000000000 The accumulator hash is a fixed length value that is used to verify that the current transaction, and all transactions before it, have occurred in the correct order and have not been tampered with.
