Thanks to the support from aelf block producers, we are glad to announce that aelf Mainnet has completed its upgrade to v1.8.0 successfully on March 17, 2024.

Here are the key advancements achieved through this upgrade:

Support decimals in NFTs

aelf enables the creation and trading of non-fungible tokens (NFTs) and semi-fungible tokens (SFTs) in fractions, allowing for fractional ownership and enhanced asset liquidity. Users can create fractional NFTs/SFTs, such as 0.1 units, and freely buy or sell any desired amount of these assets. In scenarios where a specific digital artwork holds significant value, users now have the option to purchase and own a portion of it. Subsequently, they can sell this fractional piece on platforms such as decentralised exchanges (DEXes).

Amidst the prevailing trend towards Hybrid NFTs driven by the ERC404 standard, aelf’s advancing technology is poised to meet the growing demand for more accessible digital assets and improved asset performance. This unlocks new possibilities, as digital assets on aelf can now embrace the uniqueness of NFTs and the high liquidity of fungible tokens simultaneously, offering enhanced versatility and utility to users while setting the stage for innovation. Consequently, it is anticipated to attract a broader spectrum of projects, creators, traders, and investors eager to leverage this advanced asset type, contributing to the prosperity of the aelf ecosystem and ultimately boosting mainstream cryptocurrency adoption.

‍

Support NFT creation on specified blockchain

With this upgrade to v1.8.0, aelf broadens the possibilities of NFT item creation, enabling the creation of such assets on any designated chain, whether it be the MainChain or SideChains. This advancement eliminates the necessity for data synchronisation across chains and reduces the waiting period for having NFTs directly on SideChains.

‍

Support batch token approval

Batch transactions such as batch NFT listing used to require separate approvals from users which can be time-consuming. To elevate user experience in this aspect, aelf has expanded the scope of tokens/NFTs that can be approved within a single transaction, thus enabling batch approval. This enhancement relieves users from the hassle of manually approving each asset, significantly improving transaction efficiency.

We appreciate the support and trust from our communities. aelf promises to constantly upgrade the network and infrastructure and optimise our system contracts so as to provide the best blockchain services to all of our users, developers, and partners.
