🚀 Optimizing Nostr Logos for a Faster, Leaner Future
Some think decentralization is slow or resource-heavy. But efficiency is a choice. Every unnecessary kilobyte adds up, impacting speed, user experience, and even energy consumption.
By optimizing 7 Nostr logo SVGs, I reduced file sizes without any loss in quality, making them lighter, faster, and more sustainable. Small changes like this contribute to a more efficient and accessible decentralized ecosystem.
Big thanks to nostr:nprofile1qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qgwwaehxw309ahx7uewd3hkctcqyq704qttkjyjlf47nyavw25lekas3x775rzajqgl6gzdz4z5t73dj83tnaw nostr:nprofile1qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qgawaehxw309ahx7um5wghxy6t5vdhkjmn9wgh8xmmrd9skctcqyp74yyf9p0zkateg8ttsn92w7txrffgme4hjchequ0xjuar0d3gxww8qlk4 for creating the original logo. It's great to contribute my knowledge about optimization to help improve an icon that so many in the Nostr community use.
💡 How?
🔹 Adobe Illustrator (thought its not a open source solution but later we will find a solution on this ) removes unused definitions, normalizes & compress SVG structure
🔹 SVGO then:
Rounds numbers to 2 decimal
Removes unnecessary attributes
Optimizes path data
Url: jakearchibald.github.io/svgomg/
Preserves essential style/colors
🔹 A simple CLI script combines both tools for best results!

Too bad.
But things might change soon. Keep an eye. 😉
Ho iniziato solo di recente a seguire il Bitcoin Italia Podcast. Mi sembrava il modo migliore per riprendere il contatto con la community italiana dei bitcoiner, un giro che avevo smesso di frequentare nel 2015 a seguito del mio trasferimento in Germania.
Il mio scetticismo iniziale si è presto trasformato in ammirazione per questi due soggetti che, fossero romagnoli, si autodefinirebbero orgogliosamente “due patacca”. Dietro il tono leggero si vede chiaramente il lavoro, la preparazione culturale, e soprattutto la passione.
Bravi nostr:nprofile1qy2hwumn8ghj7etyv4hzumn0wd68ytnvv9hxgqgdwaehxw309ahx7uewd3hkcqpq3vepw9xdhjzhp87lv5h7z2jgzteltmzqe4scjsn9dtwwncz6ekmsuzzfwf e Guybrush, che altro aggiungere?
Unica piccola pecca: sarebbe bello vederli attivi anche qui. 😉
https://www.lava.xyz/ is very interesting. Be able to tale a loan without losing Bitcoin custody. Did you test?
No, I didn't try Lava.
Firefish.io is a BTC-only, p2p marketplace where borrowers maintain control over their BTC collateral. Available in the EU.
Ask me for a discount code if interested. (Disclosure: I work for Firefish 😉)
Probably in the 3%-5% range depending on the LTV, duration and amount.
Bitcoin-backed loans are being discussed increasingly in the media (see Cointelegraph link below). The failures of Celsius and BlockFi have taught current market players valuable lessons about risk management. However, a question still remains: why are interest rates still so high (8%-12%) when Bitcoin is the ultimate collateral?
In my opinion, interest rates will decrease rapidly. This shift will likely begin in the US, where banks are no longer bound by the SAB 121 accounting rule. As a result, they will be able to offer financial services that involve custody of crypto assets, such as using bitcoin as collateral for loans. This development will attract significant amounts of risk-averse liquidity, and rates will inevitably decrease substantially.
The EU and the rest of the world will follow this same path at different speeds, leading to the same results. I’m glad that my company, Firefish.io, is educating the EU markets to this upcoming opportunity.

MY SAZMINING EXPERIENCE:
A CAUTIONARY TALE OF MINING EXPECTATIONS
About one year ago, I decided to try mining. After assessing the various options, from solo mining to cloud mining, I selected nostr:nprofile1qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qpq0vkwadgkfkg9vzpe04a6rhpzrd8rlw0r84qelag5hgtycrykgz3qyzqfdf since I liked the interest alignment between the company and its customers.
If you're not familiar with Sazmining (https://www.sazmining.com), it's a company that offers hosted mining services. Here's how it works:
1. You purchase a mining rig from Sazmining, which gets shipped and deployed at one of their farms (located in Paraguay or Norway).
2. You pay a monthly hosting fee that covers energy and basic maintenance costs.
3. The hashrate of your rig is directed to the Luxor mining pool.
4. You earn sats, with Sazmining taking a 15% fee on your earnings.
In this scheme, Sazmining has all the incentives to keep your rig running constantly and efficiently.
Sazmining claims that mining with them will allow you to acquire Bitcoin at a much lower price than the market price. As of today, they claim on their homepage that you can get 1 BTC for $58K, which would be almost a 50% discount.
However, my personal experience tells a different story. I'd like to share my numbers with you. I purchased a Bitmain S21 for $5K and had it shipped to the Paraguay farm where the energy costs (0.047$/KWh) are covered by the hosting subscription ($120/month). Note that your monthly fee may vary slightly due to factors like local energy curtailments or overconsumption by your rig.
When I purchased my mining rig from Sazmining, they estimated that I could reach break-even within 15 months (by May 2025). At that time, their website featured a useful simulator that allowed me to experiment with different scenarios and estimate my potential returns. Unfortunately, this simulator is no longer available.
However, I've had to revise that forecast significantly. Today, my optimistic estimate suggests that it will take around 27 months (until July 2026) for me to reach break-even. Notably, this change isn't of course due to any decrease in Bitcoin's price.
So far, I’ve earned 3.4M sats, but the pace of payouts to my wallet is getting slower: from 340K every 3 weeks at the start, to 340K every 6 weeks now. Quite likely this is due to the significant increase in the global hashrate.
Combining both upfront hardware expenses ($5K) along accumulated hosting fees ($1300), I’ve paid a 110K USD/BTC price for my 3.4M sats!
After one year I’m still pretty far from enjoying the advertised discount and, of course, if I had opted for DCA purchases, I would have enjoyed much better results.
Hopefully, my return on investment will improve in the coming months, but there are no certainties, since global hashpower keeps growing.
I have the feeling that any other strategy (e.g. DCA) would have performed much better over the past year.
nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqydhwumn8ghj7mn0wd68ytf39ehxymewv9hxwctwdyhxxmcqyrt7asl5deg6uzj86l52kldet37c5j3n8swz7ujpd9f2cgka37qcsnr5hsn (Sazmining CEO) asked, in a comment to my post, what nostr:nprofile1qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qpq0vkwadgkfkg9vzpe04a6rhpzrd8rlw0r84qelag5hgtycrykgz3qyzqfdf could do to improve transparency.
Well, Sazmining should consider clearly stating the criteria and assumptions used to derive the advertised $58K/BTC purchase price. This will enable prospective clients to make a more informed decision.
Additionally, Sazmining might publish aggregate data about users/rigs and their contributions to Luxor's hashrate, allowing everyone to verify that they are receiving a fair share of mined sats.
Finally, Sazmining might release quarterly financial reports to reassure customers that their trust is reflected in the company's profit and loss statement (P&L) and balance sheet.
This has been puzzling me for a long time: why are we still using Telegram, especially why are we using Telegram groups?!
It’s now common knowledge that Telegram groups do not offer end-to-end encryption. Isn't this enough to consider switching to one of the many alternative platforms that do offer end-to-end encryption?
I don’t care much about the controversy surrounding Telegram’s founder Pavel Durov, or the total lack of transparency that characterizes the company behind it.
I’m especially surprised by bitcoiners! 😩
I would expect them to stay as far as possible from the most important platform for scammer, shitcoiners, airdroppers, rugpullers, … Instead, even reputable, competent, and honest bitcoiners use Telegram regularly (to plan meetups, for online courses, to share educational material, …)
Nostr might be still immature, but an app like nostr:nprofile1qy2hwumn8ghj7etyv4hzumn0wd68ytnvv9hxgqgdwaehxw309ahx7uewd3hkcqpqtm99pgz2lth724jeld6gzz6zv48zy6xp4n9xu5uqrwvx9km54qaq743a4w is already preferable to Telegram. And it can also serve as a great way to onboard more people to Nostr.

The lesson I learned is: “not your energy, not your hashrate”. 😉
I guess Sazmining will take care of shipping the rig to the buyer or they could even buy it themselves and resell it to their customers, but there is no detailed information.
I think that the longer time to reach BE is mostly due to the increased global hashrate. We certainly can't blame the price. 😉
Transparency is key when you run a business based on trust.
And Sazmining could do much better in that department.
It is indeed KYC-free, but I'm not that interested in this aspect.
If this is their value proposition, they should advertise it openly, not claiming that users will get bitcoin at a discounted price.
I could sell my rig and deploy it somewhere else.
Not sure it is worth the trouble though.
Being a Sazmining customer implies a lot of trust in the company. I took the risk and I wanted to share the so-and-so outcome.

Interestingly, none of the crypto accounting services mentioned in my previous post has an official profile on Nostr. I’d really love to hear about the measures they have in place to defend the trove of customer data stored on their servers.
Even more interesting is the fact that none of these services moved the app logic to the browser and, by using client-side encryption, designed its service in a way that minimizes the amount of user data exposed to the server.
If anyone from Koinly, CryptoPanda, BlockPit, CoinLedger, TaxBit, CryptoTax, or other similar services is reading this and willing to share their perspective, I would be interested in hearing from you. Thank you!

Happy to help. Thanks!
In 2020, ~270k bitcoiners around the world freaked out because of the data breach suffered by Ledger. The leaked information consisted “only” of email addresses, names, phone numbers, and home addresses. This data was later used for targeted phishing campaigns, and, allegedly, a few physical attacks as well.
Fast forward to today: bitcoiners are totally cool connecting their wallets and exchange accounts to crypto accounting services (e.g.: Koinly, CoinLedger, TaxBit, Coinpanda, ...) that download and store transactions and balances on their servers alongside personal data. These services could definitely leak a richer data set than Ledger.
An attractive target for attackers interested in chasing crypto riches. Essentially a honeypot waiting to be exploited.
Moreover, these accounting services are often run by small startups with a questionable security mindset, and undisclosed security policies and protocols. This raises concerns about their ability to protect user data.
What do you think? Am I missing something here?
(If you believe that "tax is theft", then this question may not be relevant to you, as it's unlikely you would use accounting solutions designed to help with tax compliance.)
