We briefly mentioned Jackdaw memos in our <a data-mce-href="https://jackdawtoken.com/blog/jackdaw--anatomy-of-a-ravencoin-main-asset" href="https://jackdawtoken.com/blog/jackdaw--anatomy-of-a-ravencoin-main-asset" title="Jackdaw: Anatomy of a Ravencoin Main Asset" target="_blank" rel="noopener">first article</a> but wanted to take a moment to expand on exactly what Jackdaw memos are. One of the most interesting features of Jackdaw, and Ravencoin Assets in general, is the ability to permananetly and immutably store information by simply transacting.Any Jackdaw transaction can have a "memo" added to it. That memo can be in the form of a transaction ID or an IPFS hash. Whichever you choose, the information is stored to the Ravencoin blockchain forever, making Jackdaw memos a great way to add additional permanent information or other metadata to a transaction.[1] In theory, a user could store an enormous amount of metadata by sending themselves Jackdaw tokens (creating a transaction) containing IPFS hashes where said data is stored. The Ravencoin blockchain will store that IPFS hash (or transaction ID) permananetly, allowing for users to access the data they've stored in Jackdaw memos on the blockchain, forever. Memos are a great way to store virtually any metadata permanently, as both Ravencoin and IPFS are decentralized immutable solutions. Once a file is pinned to IPFS, no one can alter the hash (content ID) or the data it contains.[2] You can use Jackdaw memos to store additional data about a transaction (including a transaction ID itself) or any other range of solutions that fit your needs. Perhaps simple file storage or record keeping, perhaps something more complex like game or website. In theory, memos could also be used for transaction verification should such a system come into existence. Users can add messages, websites, or any other data they desire to a Jackdaw memo and create an immutable record reflecting anything they wish. This represents a powerful record keeping and data storage solution for anyone using the Jackdaw token. Try it out using a Ravencoin Wallet that supports the memo feature!

Jackdaw Memos: Metadata Set in Stone

Western Jackdaw flying on bright background

Introduction:This article assumes you've read the <a data-mce-href="https://jackdawtoken.com/whitepaper" href="https://jackdawtoken.com/whitepaper" title="Jackdaw ($JDAW) Whitepaper" target="_blank" rel="noopener">Jackdaw Whitepaper</a> and understand Jackdaw's basic tokenomics and goals. Its often noted in the Jackdaw community that Jackdaw ($JDAW) has far fewer technical and social attack vectors than its token counter-parts on other blockchains. Selecting Ravencoin as Jackdaw's parent blockchain wasn't by accident, it came after years of observation and testing with Ravencoin and other blockchains. Jackdaw isn't your standard cryptocurrency token, its a Ravencoin Asset! Ravencoin was purpose-built for Asset issuance and transfer, and a lot of thought and care went into this element of Ravencoin's design and the security required to maintain it. Jackdaw was issued in a way where it can showcase some of the advantages of Ravencoin Assets while maintaining a decentralized, minimalistic, cypherpunk ethos. This paper is intended to highlight some of the many advantages both Jackdaw and Ravencoin hold over other blockchain standards.Exploring Assets:First we should explore some of Ravencoins design and history to understand the technology backing the Jackdaw token. Ravencoin was launched in January of 2018 as a purely Proof of Work blockchain specializing in Asset issuance and transfer.[<a data-mce-href="https://ravencoin.org/assets/documents/Ravencoin.pdf" href="https://ravencoin.org/assets/documents/Ravencoin.pdf" title="Ravencoin Whitepaper" target="_blank" rel="noopener">1</a>] Ravencoin does not utilize coin staking mechanisms, such as masternodes or validators. Instead, miners spend real world energy to run the Raven network and produce new coins.[<a data-mce-href="https://ravencoin.org/assets/documents/X16R-Whitepaper.pdf" href="https://ravencoin.org/assets/documents/X16R-Whitepaper.pdf" title="Ravencoin X16R Whitepaper" target="_blank" rel="noopener">2</a>] These same miners spend energy confirming Jackdaw and other Ravencoin Asset transactions, making Ravencoin Assets true Layer 1 tokens. The advantages of PoW for security and immutability have been well discussed[<a data-mce-href="https://bitcoinmagazine.com/technical/proof-of-work-superior-for-bitcoin" href="https://bitcoinmagazine.com/technical/proof-of-work-superior-for-bitcoin" title="Bitcoin Magazine Proof of Work" target="_blank" rel="noopener">3</a>], so we'll skip that here in favor of discussing the core of this paper, the Ravencoin Asset. Before we go any further, its highly recommended that you familiarize yourself with the "All About Assets" article on Ravencoin.org. This will help give you a basic unserstanding of Ravencoin Assets.[<a data-mce-href="https://ravencoin.org/assets/" href="https://ravencoin.org/assets/" title="Ravencoin All About Assets" target="_blank" rel="noopener">4</a>] Keep in mind, Jackdaw is a Ravencoin "Main Asset" token.Now that you have a basic understanding of a "Ravencoin Asset" (interchangably called a "Ravencoin Token") and the different types that can be created, lets look at some of the clear advantages the Jackdaw token has.&nbsp; Human Readable Unique Token Name:&nbsp;Not a complex smart contract or address, Ravencoin Assets are like domain names for value. The Jackdaw token is simply called "JACKDAW" on the Ravencoin blockchain, no confusion possible, as each Ravencoin Asset name is unique. There will never be another token named "JACKDAW" on the Ravencoin blockchain, no need to check confusing contracts or addresses. This eliminates most common social attack vectors such as spoofing and fraud.[<a data-mce-href="https://tronblack.medium.com/ravencoin-assets-vs-erc-20-9ff1593c100d" href="https://tronblack.medium.com/ravencoin-assets-vs-erc-20-9ff1593c100d" title="Ravencoin Assets VS ERC-20" target="_blank" rel="noopener">5</a>] Transaction Memos, user-stored data:Jackdaw Memos are immutably stored IPFS data that can be added to any Jackdaw transaction, just as they can be with any normal Ravencoin transaction. This allows users to effectively store any metadata they desire using the Jackdaw token by simply transacting. This could be used for records, messages, or any other metadata the user wishes to store using their Jackdaw.[<a data-mce-href="https://tronblack.medium.com/ravencoin-memos-84bdbd0dfe1c" href="https://tronblack.medium.com/ravencoin-memos-84bdbd0dfe1c" title="Ravencoin Memos" target="_blank" rel="noopener">6</a>] UTXO Model, traceable from issuance:Ravencoin Assets benefit from Ravencoins UTXO model. Jackdaw utilizes this model to present a fully auditable decentralized token, traceable back to its issuance. All Jackdaw transactions are visible and confirmed on the blockchain by miners, not handled by smart contracts which add and subtract coins. This means Ravencoin Assets are true Layer 1 tokens and benefit from the same base functionality as their parent blockchain.[<a data-mce-href="https://tronblack.medium.com/ravencoin-better-than-erc-20-88a276d3e434" href="https://tronblack.medium.com/ravencoin-better-than-erc-20-88a276d3e434" title="Ravencoin better than ERC-20" target="_blank" rel="noopener">7</a>] Secure, audited code:Ravencoin has passed a community funded independant security audit. Assets created on Ravencoin could not reside on a more secure, time and battle tested blockchain.[<a data-mce-href="https://ravencoin.foundation/code-security-audit/" href="https://ravencoin.foundation/code-security-audit/" title="Ravencoin Security Code Audit Ravencoin Foundation" target="_blank" rel="noopener">8</a>]&nbsp; Sources:[1] <a data-mce-href="https://ravencoin.org/assets/documents/Ravencoin.pdf" href="https://ravencoin.org/assets/documents/Ravencoin.pdf" title="Ravencoin Whitepaper" target="_blank" rel="noopener">https://ravencoin.org/assets/documents/Ravencoin.pdf</a>[2] <a data-mce-href="https://ravencoin.org/assets/documents/X16R-Whitepaper.pdf" href="https://ravencoin.org/assets/documents/X16R-Whitepaper.pdf" title="Ravencoin X16R Whitepaper" target="_blank" rel="noopener">https://ravencoin.org/assets/documents/X16R-Whitepaper.pdf</a>[3] <a data-mce-href="https://bitcoinmagazine.com/technical/proof-of-work-superior-for-bitcoin" href="https://bitcoinmagazine.com/technical/proof-of-work-superior-for-bitcoin" title="Bitcoin Magazine Proof of Work" target="_blank" rel="noopener">https://bitcoinmagazine.com/technical/proof-of-work-superior-for-bitcoin</a>[4] <a data-mce-href="https://ravencoin.org/assets/" href="https://ravencoin.org/assets/" title="Ravwncoin All About Assets" target="_blank" rel="noopener">https://ravencoin.org/assets/</a>[5] <a data-mce-href="https://tronblack.medium.com/ravencoin-assets-vs-erc-20-9ff1593c100d" href="https://tronblack.medium.com/ravencoin-assets-vs-erc-20-9ff1593c100d" title="Ravencoin Assets VS ERC-20" target="_blank" rel="noopener">https://tronblack.medium.com/ravencoin-assets-vs-erc-20-9ff1593c100d</a>[6] <a data-mce-href="https://tronblack.medium.com/ravencoin-memos-84bdbd0dfe1c" href="https://tronblack.medium.com/ravencoin-memos-84bdbd0dfe1c" title="Ravencoin Memos" target="_blank" rel="noopener">https://tronblack.medium.com/ravencoin-memos-84bdbd0dfe1c</a>[7] <a data-mce-href="https://tronblack.medium.com/ravencoin-better-than-erc-20-88a276d3e434" href="https://tronblack.medium.com/ravencoin-better-than-erc-20-88a276d3e434" title="Ravencoin better than ERC-20" target="_blank" rel="noopener">https://tronblack.medium.com/ravencoin-better-than-erc-20-88a276d3e434</a>[8] <a data-mce-href="https://ravencoin.foundation/code-security-audit/" href="https://ravencoin.foundation/code-security-audit/" title="Ravencoim Security Code Audit Ravencoin Foundation" target="_blank" rel="noopener">https://ravencoin.foundation/code-security-audit/</a>
