Meanwhile, Bitcoin transaction fees have soared to two-year highs since Ordinals became popular, leading some in the community to blast the craze.

The emergent STAMPS (Secure Tradeable Art Maintained Securely) protocol is proposing a different method of embedding image data into the OG blockchain, making different tradeoffs compared to the inscription technology that exploded in popularity earlier this year. Rather than storing image data within prunable transaction witness data, “Bitcoin Stamps” store it directly within spendable…

Litecoin was created in 2011 as a rival to Bitcoin. The idea was to make a peer-to-peer cash system cheaper than the oldest and most well-known digital currency.
