v1.2.1 (Bug Fix of v1.2.0) - Mandatory Update

包含如下改变：

1. 修复同步问题

提示：
由于本次硬分叉新增8GiB扇区的支持，所以升级时需要下载对应的零知识证明参数。请按如下方式配置IPFS Gateway并按需进行参数下载的操作：

# 删除IPFS_GATEWAY环境变量，从而使用FileStar程序中默认的源
unset IPFS_GATEWAY
# 或使用FileStar京东云的源
export IPFS_GATEWAY=https://filestar-proofs.s3.cn-east-1.jdcloud-oss.com/ipfs/
# 如果进行8GiB扇区封装，建议提前手动下载完整的封装参数（否则只需要重启的时候自动下载验证参数即可）
lotus-miner fetch-params 8GiB

It includes the following changes:

1. Fix synchronization issues

Tips:
Since this hard fork adds 8GiB sector support, it is necessary to download the corresponding zero-knowledge proof parameters during the upgrade. Please configure the IPFS Gateway and download the parameters according to your needs as follows:

# Delete the IPFS_GATEWAY environment variable to use the default source in the FileStar program
unset IPFS_GATEWAY
# Or use the FileStar source from JDCloud
export IPFS_GATEWAY=https://filestar-proofs.s3.cn-east-1.jdcloud-oss.com/ipfs/
# If you are sealing 8GiB sectors, it is recommended to manually download the parameters in advance

Inflation (v1.2.0) - Hard Fork - Mandatory update

如今，FileStar全网算力已达到36PiB。为了让更多矿工能够加入到网络中，我们发布了v1.2.0版本Inflation（膨胀）。
它包括以下改变：

1. 支持8GiB扇区；
2. 提高block gas limit；
3. 修复了一些bug。

通过这些改变，更多的矿机设备（例如基于Intel CPU的服务器）将获得网络的准入，参与到FileStar的挖矿中来。

该版本是一次强制升级。分叉将会发生在高度184560，即北京时间12月30日下午2点。请在这之前完成升级。分叉之后，8GiB扇区的矿工账户将开放注册，矿工可以通过lotus-miner init --sector-size 8GiB命令来完成注册。8GiB扇区的封装过程对硬件的要求大幅度降低，且封装效率提升了一倍左右。这是一次非常具有创新性的尝试，它将大幅度节省存储和检索的时间。我们坚信这将对更多的矿工和技术爱好者敞开Web 3.0的大门。

Today, the Network Storage Power of FileStar has reached 36 PiB. In order to allow more miners to join the network, we released version v1.2.0 (Inflation).
It includes the following changes:

1. Support 8GiB sector;
2. Increase the block gas limit;
3. Fixed some bugs.

Through these changes, more mining machines (such as Intel CPU-based servers) will gain access to the network and participate in FileStar mining.

This version is a mandatory upgrade. The fork will happen at the height of 184560, which is 2 PM on December 30th, GMT+8. Please complete the upgrade before then. After the fork, miner accounts for the 8GiB sector will be open for registration. Miners can complete the registration by command lotus-miner init --sector-size 8GiB. The sealing process of the 8GiB sector has greatly reduced the hardware requirements, and the sealing efficiency has been doubled. This is a very innovative attempt, which will greatly save storage and retrieval time. We firmly believe that this will open the door of Web 3.0 to more miners and technology enthusiasts.

BigBang (v1.0.0)

这是FileStar主网的第一个版本。它叫做BigBang，代表了所有星星的起源。
它包括以下改变：

1. 去除前置抵押
2. 只需32GiB存力即可出块
3. 去除区块奖励的25%立即解锁

我们坚信这些改变能为矿工和用户构造一个更好的生态环境。

接下来，我们将会进行一系列空投活动，这将标志着主网的正式启动。在此之前，矿工们可以有充足的时间进行准备。

This is the first version of the FileStar mainnet. It's named BigBang which stands for the origin of all stars.
It contains the following changes:

1. Remove the Initial Pledge
2. Blocks can be generated with only 32GiB storage power
3. Remove the 25% immediate unlock of the block reward

We believe these changes can build a better ecosystem for miners and users.

Next, we will conduct a series of airdrop activities, which will represent the launch of the mainnet. Before that, miners can have enough time to make preparations.
