Today, with the increasing development of blockchain technology, Opera chain has become a project that has attracted much attention due to its unique database storage and consensus mechanism. This article will delve into the characteristics of the FTM token and its important role in the Opera chain.
Database storage and real-time pruning
Opera chain uses database storage to manage its world state, which includes account information, virtual machine byte code, smart contract storage, etc. A distinctive feature of this database is live pruning, a mechanism that automatically removes historical data and reduces the storage needs of validators as the blockchain grows.
In previous blockchain systems, the pruning process usually required verification nodes to go offline, which could lead to financial and operational risks. However, the Opera chain's real-time pruning function allows validators to prune data without going offline, ensuring continued operations while saving disk space and costs by immediately discarding historical data.
How instant trim works
On-the-fly pruning is achieved by dividing the database into two types: LiveDB and ArchiveDB. LiveDB only contains the world state of the current block, while ArchiveDB saves the world state of all historical blocks. The verifier only needs to use LiveDB, and the archive node has both LiveDB and ArchiveDB to handle historical data requests through the RPC interface.
Opera's database storage adopts an efficient tree or hierarchical structure, which simplifies the process of data retrieval. At the same time, it provides cryptographic signatures for world states and uses an incremental version of the prefix algorithm to implement archiving functions. In addition, Opera uses a native disk format rather than indirectly saving world state through a key-value store like LevelDB or PebbleDB.
FTM Tokens and Proof of Stake Mechanism
The security of Opera chain relies on the Proof-of-Stake (PoS) mechanism. In Opera’s PoS system, validators must lock their FTM (Opera’s native token). If they act maliciously within the network, they will lose their tokens. This mechanism effectively incentivizes validators to act in the best interest of the network because their funds are directly tied to the security of the network.
Compared with the traditional Proof-of-Work mechanism, PoS has significant advantages in energy efficiency because the verifier does not need to perform complex operations. This method not only improves network security, but also reduces the cost of resisting Sybil attacks. Sybil attacks are when malicious actors run large numbers of validators in order to gain insecure influence in the network. The PoS mechanism effectively increases the cost of attacks by increasing the cost of setting up these validators and allowing the network to punish malicious actors.
Validator requirements
In the Opera chain, validator nodes need to lock at least 50,000 FTM to verify transactions and generate blocks. This requirement ensures that a validator’s participation in the network is not just formal, but is actually connected to their economic interests.
Application and future of FTM tokens: In addition to playing an important role in the verification process, FTM tokens can also be used to pay transaction fees, participate in governance, etc. As the Opera chain ecosystem continues to expand, the application scenarios of FTM are also increasing.
In the future, FTM tokens may play a greater role in decentralized finance (DeFi), non-fungible tokens (NFT) and other blockchain applications. As more projects come online, the liquidity and value of FTM will be further enhanced.
Summarize
Opera Chain provides new thinking for the development of blockchain technology with its innovative database storage and equity certification mechanism. As the core asset of Opera chain, FTM tokens not only ensure the security of the network, but also provide users with rich application scenarios. As technology continues to evolve, FTM tokens will surely occupy an increasingly important position in the blockchain ecosystem.
By in-depth understanding of the mechanisms of FTM tokens and Opera chain, we can better grasp the future development trend of blockchain technology. Whether as an investor or a technology enthusiast, paying attention to FTM tokens is undoubtedly a wise choice.
