Blocks are data structures within the blockchain database, where transaction data in a cryptocurrency blockchain are permanently recorded. A block records some or all of the most recent transactions not yet validated by the network sugar trail slot. Once the data are validated, the block is closed. Then, a new block is created for new transactions to be entered into and validated.

In 2024, stablecoins reached an all-time high of $200 billion in circulating supply, dominated by market leaders Tether and Circle. These digital currencies rely on blockchain networks such as Ethereum, Solana, and Tron to facilitate seamless, borderless transactions.
Collectively, these milestones cemented 2024 as the year the crypto industry proved itself to be an unstoppable force on the global stage. As the industry shifts its focus to 2025, here are my seven predictions of major events we can expect to take place next year.
Previously, digital assets were classified as intangible assets, which forced companies to write down impaired holdings while prohibiting the recognition of unrealized gains. This conservative approach often understated the true value of crypto holdings on corporate balance sheets. The updated rules address these limitations, enabling more accurate financial reporting and making cryptocurrencies a more attractive asset for corporate treasuries.

One of the major differences between Bitcoin and Ethereum’s economics is that the latter is not deflationary, i.e. its total supply is not limited. Ethereum’s developers justify this by not wanting to have a “fixed security budget” for the network. Being able to adjust ETH’s issuance rate via consensus allows the network to maintain the minimum issuance needed for adequate security.
In January 2022, the Ethereum Foundation announced the decision to remove the “Ethereum 2.0” terminology to “save all future users from navigating this confusing mental model.” It went on to explain that the previously-referred-to terms of “Ethereum 1.0” would be branded the “execution layer,” while “Ethereum 2.0” will be called the “consensus layer”. This is ultimately to provide a more accurate version of the Ethereum roadmap.
Ethereum’s own purported goal is to become a global platform for decentralized applications, allowing users from all over the world to write and run software that is resistant to censorship, downtime and fraud.
